Prolactin replacement fails to inhibit reactivation of gonadotropin secretion in rams treated with melatonin under long days. (1/1549)

This study tested the hypothesis that prolactin (PRL) inhibits gonadotropin secretion in rams maintained under long days and that treatment with melatonin (s.c. continuous-release implant; MEL-IMP) reactivates the reproductive axis by suppressing PRL secretion. Adult Soay rams were maintained under long days (16L:8D) and received 1) no further treatment (control, C); 2) MEL-IMP for 16 wk and injections of saline/vehicle for the first 8 wk (M); 3) MEL-IMP for 16 wk and exogenous PRL (s.c. 5 mg ovine PRL 3x daily) for the first 8 wk (M+P). The treatment with melatonin induced a rapid increase in the blood concentrations of FSH and testosterone, rapid growth of the testes, an increase in the frequency of LH pulses, and a decrease in the LH response to N-methyl-D,L-aspartic acid. The concomitant treatment with exogenous PRL had no effect on these reproductive responses but caused a significant delay in the timing of the sexual skin color and growth of the winter pelage. These results do not support the hypothesis and suggest that PRL at physiological long-day concentrations, while being totally ineffective as an inhibitor of gonadotropin secretion, acts in the peripheral tissues and skin to maintain summer characteristics.  (+info)

The localisation of 2-carboxy-D-arabinitol 1-phosphate and inhibition of Rubisco in leaves of Phaseolus vulgaris L. (2/1549)

A recent controversial report suggests that the nocturnal inhibitor of Rubisco, 2-carboxy-D-arabinitol 1-phosphate (CAIP), does not bind to Rubisco in vivo and therefore that CA1P has no physiological relevance to photosynthetic regulation. It is now proved that a direct rapid assay can be used to distinguish between Rubisco-bound and free CA1P, as postulated in the controversial report. Application of this direct assay demonstrates that CA1P is bound to Rubisco in vivo in dark-adapted leaves. Furthermore, CA1P is shown to be in the chloroplasts of mesophyll cells. Thus, CA1P does play a physiological role in the regulation of Rubisco.  (+info)

Intrapreoptic microinjection of GHRH or its antagonist alters sleep in rats. (3/1549)

Previous reports indicate that growth hormone-releasing hormone (GHRH) is involved in sleep regulation. The site of action mediating the nonrapid eye movement sleep (NREMS)-promoting effects of GHRH is not known, but it is independent from the pituitary. GHRH (0.001, 0. 01, and 0.1 nmol/kg) or a competitive antagonist of GHRH (0.003, 0.3, and 14 nmol/kg) was microinjected into the preoptic area, and the sleep-wake activity was recorded for 23 hr after injection in rats. GHRH elicited dose-dependent increases in the duration and in the intensity of NREMS compared with that in control records after intrapreoptic injection of physiological saline. The antagonist decreased the duration and intensity of NREMS and prolonged sleep latency. Consistent alterations in rapid eye movement sleep (REMS) and in brain temperature were not found. The GHRH antagonist also attenuated the enhancements in NREMS elicited by 3 hr of sleep deprivation. Histological verification of the injection sites showed that the majority of the effective injections were in the preoptic area and the diagonal band of Broca. The results indicate that the preoptic area mediates the sleep-promoting activity of GHRH.  (+info)

Hypoglycemia and torpor in Siberian hamsters. (4/1549)

We tested whether reduced blood glucose concentrations are necessary and sufficient for initiation of torpor in Siberian hamsters. During spontaneous torpor bouts, body temperature (Tb) decreases from the euthermic value of 37 to <31 degrees C. Among hamsters that displayed torpor during maintenance in a short-day length (10 h light/day) at an air temperature of 15 degrees C, blood glucose concentrations decreased significantly by 28% as Tb fell from 37 to <31 degrees C and increased during rewarming so that by the time Tb first was >36 degrees C, glucose concentrations had returned to the value preceding torpor. Hamsters did not display torpor when maintained in a long-day length (16 h light/day) and injected with a range of insulin doses (1-50 U/kg body mass), some of which resulted in sustained, pronounced hypoglycemia. We conclude that changes in blood glucose concentrations may be a consequence rather than a cause of the torpid state and question whether induction of torpor by 2-deoxy-D-glucose is due to its general glucoprivic actions.  (+info)

Phenotypic differences in the GnRH neuronal system of deer mice Peromyscus maniculatus under a natural short photoperiod. (5/1549)

The neural mechanisms by which short photoperiod induces gonadal regression among seasonally breeding mammals are not well understood. One hypothesis suggests that the proximate cause of seasonal gonadal regression is a photoperiod-induced modification in GnRH secretion. This hypothesis is indirectly supported by our recent findings using immunocytochemistry which identified specific photoperiod-induced adjustments in the number and morphology of GnRH containing neurones between reproductively competent and reproductively regressed laboratory housed male deer mice. Herein, we report that the GnRH neuronal system is similarly affected in reproductively responsive and nonresponsive wild male deer mice Peromyscus maniculatus exposed to a natural short photoperiod. The distribution of immunoreactive (IR)-GnRH neurones was nearly identical in field caught animals and those housed under artificial photoperiod in the laboratory. Compared with reproductively nonresponsive males, reproductively responsive mice from the field population possessed a greater total number of IR-GnRH neurones, a greater number of IR-GnRH neurones within the lateral hypothalamus, and a greater proportion of bipolar IR-GnRH neurones. Each of these distributional and morphological characters was consistent with our findings in laboratory housed male deer mice exposed to an artificial short photoperiod. Taken together, these data underscore the validity of using an artificial photoperiod to evaluate seasonal adjustments in reproductive function in the laboratory.  (+info)

Annual cycle in LH and testosterone release in response to GnRH challenge in male woodchucks (Marmota monax). (6/1549)

Testosterone and LH concentrations were determined in serum samples obtained before and 15 min after injections of GnRH (1 microgram kg-1) administered at 4-7 week intervals over 20 months to groups of male woodchucks (n = 6-7) born and maintained in Northern Hemisphere (boreal) versus Southern Hemisphere (austral) simulated natural photoperiods, beginning at 18-24 months of age. Nadir and peak unstimulated testosterone (0.1 +/- 0.01 and 7.0 +/- 0.1 ng ml-1, respectively) and LH (0.8 +/- 0.2 and 8.1 +/- 1.1 ng ml-1, respectively) concentrations did not differ in boreal versus austral males. In the five boreal and five austral males that were confirmed to be photoentrained, basal (pre-GnRH) concentrations of LH and testosterone were lowest in summer, increased simultaneously in late autumn or early winter, and declined in the spring. GnRH stimulated some LH release throughout the year except for a 1-4 month period in the summer. The initial annual increase in the LH response to GnRH occurred in early autumn, and in 17 of 20 cycles it occurred 1-2 months before the initial increase in basal LH was detected. In the three free-running males not entrained to the photoperiod, the endocrine patterns were similar but were advanced by several months. The results demonstrate that in woodchucks there is a late autumn increase in LH secretion associated with the onset of testicular recrudescence, and an early autumn increase in pituitary response to GnRH before a detectable increase in serum testosterone.  (+info)

Abnormal photoresponses and light-induced apoptosis in rods lacking rhodopsin kinase. (7/1549)

Phosphorylation is thought to be an essential first step in the prompt deactivation of photoexcited rhodopsin. In vitro, the phosphorylation can be catalyzed either by rhodopsin kinase (RK) or by protein kinase C (PKC). To investigate the specific role of RK, we inactivated both alleles of the RK gene in mice. This eliminated the light-dependent phosphorylation of rhodopsin and caused the single-photon response to become larger and longer lasting than normal. These results demonstrate that RK is required for normal rhodopsin deactivation. When the photon responses of RK-/- rods did finally turn off, they did so abruptly and stochastically, revealing a first-order backup mechanism for rhodopsin deactivation. The rod outer segments of RK-/- mice raised in 12-hr cyclic illumination were 50% shorter than those of normal (RK+/+) rods or rods from RK-/- mice raised in constant darkness. One day of constant light caused the rods in the RK-/- mouse retina to undergo apoptotic degeneration. Mice lacking RK provide a valuable model for the study of Oguchi disease, a human RK deficiency that causes congenital stationary night blindness.  (+info)

Long-day up-regulation of a GAMYB gene during Lolium temulentum inflorescence formation. (8/1549)

Long-day exposure of the grass Lolium temulentum may regulate flowering via changes in gibberellin (GA) levels. Therefore, we have examined both GA levels and expression of a MYB transcription factor that is specific to the GA signal transduction pathway in monocots. This MYB gene from L. temulentum shows over 90% nucleotide identity with the barley and rice GAMYB genes, and, like them, gibberellic acid (GA3) up-regulates its expression in the seed. Furthermore, cDNAs of both the barley and L. temulentum GAMYB show the same simple patterns of hybridization with digests of L. temulentum genomic DNA. Compared with vegetative shoot apices of L. temulentum, the in situ mRNA expression of LtGAMYB does not change during the earliest steps of "floral" initiation at the apex. However, by 100 h (the double-ridge stage of flowering) its expression increased substantially and was highest in the terminal and lateral spikelet sites. Thereafter, expression declined overall but then increased within stamen primordia. Prior to increased LtGAMYB expression, long-day exposure sufficient to induce flowering led to increased (5- to 20-fold) levels of GA1 and GA4 in the leaf. Thus, increases first in GA level in the leaf followed by increased expression of LtGAMYB in the apex suggest important signaling and/or response roles in flowering.  (+info)

This study investigated the effect of different photoperiods on acetaminophen-induced hepatotoxicity in rats. Twenty four adult male rats (average weight = 160±7g) were conditioned to different photoperiod regimens for 6 weeks. At the end of the 6-week period, rats exposed to normal, short and long photoperiods received oral acetaminophen (2g/kg body weight) while in the control group, exposed to normal photoperiod, received oral saline. Rats were sacrificed 24 h after acetaminophen administration by cervical dislocation and blood was collected by cardiac puncture for the estimation of liver enzymes activities. Liver tissues were excised and homogenized for estimation of liver malondialdehyde (MDA) concentration. Elevation of serum levels of alanine and aspartate transaminases and alkaline phosphatase caused by acetaminophen intoxication were not affected in rats subjected to long photoperiod while these parameters were significantly (P,0.05) reduced in rats subjected to short photoperiod. ...

The transition of the apical meristem from vegetative to reproductive growth is a critical event in the life cycle of a plant. In rice, the timing of this transition affects the timing of heading. This timing, or heading date, is one of the critical traits considered for adapting rice to different cultivation areas and cropping seasons. Rice is a short-day (SD) plant; its heading is promoted by short photoperiods. The response of the plant to length of day (referred to as photoperiod sensitivity [PS]) and its basic vegetative growth determine the heading date of rice. Many genetic studies of heading date have been performed, and several genes controlling PS in rice have been genetically identified, including Se1 (Lm), Se3 to Se7, and E1 to E3 (Yokoo et al., 1980; Yamagata et al., 1986; Poonyarit et al., 1989; Sano, 1992; Yokoo and Okuno, 1993; Tsai, 1995; Kinoshita, 1998). However, only one gene involving photoperiod response in rice has been cloned, Se5 (Izawa et al., 2000). Little is known ...

EARLY FLOWERING3 redundancy fine-tunes photoperiod sensitivity - Open Access RepositoryEARLY FLOWERING3 redundancy fine-tunes photoperiod sensitivity - Open Access Repository
Three pea (Pisum sativum) loci controlling photoperiod sensitivity, HIGH RESPONSE (HR), DIE NEUTRALIS (DNE), and STERILE NODES (SN), have recently been shown to correspond to orthologs of Arabidopsis (Arabidopsis thaliana) circadian clock genes EARLY FLOWERING3 (ELF3), ELF4, and LUX ARRHYTHMO, respectively. A fourth pea locus, PHOTOPERIOD (PPD), also contributes to the photoperiod response in a similar manner to SN and DNE, and recessive ppd mutants on a spring-flowering hr mutant background show early, photoperiod-insensitive flowering. However, the molecular identity of PPD has so far remained elusive. Here, we show that the PPD locus also has a role in maintenance of diurnal and circadian gene expression rhythms and identify PPD as an ELF3 co-ortholog, termed ELF3b. Genetic interactions between pea ELF3 genes suggest that loss of PPD function does not affect flowering time in the presence of functional HR, whereas PPD can compensate only partially for the lack of HR. These results provide an ...

In Arabidopsis and other species, light and photoperiod signals are integrated at the level of FT expression. Late-flowering photoperiod pathway mutants in Arabidopsis such as gi, fkf1, and cry2 have reduced FT expression under LD conditions, whereas early-flowering mutants have increased FT expression. In pea, LATE1 is clearly necessary for induction of the FT homolog FTL (Fig. 5B), demonstrating that both the GI-FT regulatory interaction and the association between photoperiod-insensitive late flowering and low expression of FT homologs are conserved in pea. Our preliminary studies of other photoperiod response mutants, such as phyA and SD-grown wild-type plants, suggest that they also show altered FTL expression (V. Hecht and C. Knowles, unpublished data), in support of a role for FTL as a target of the photoperiod pathway.. In Arabidopsis and rice, effects of GI on FT expression are mediated at least in part through changes in the expression of CO genes (Suárez-López et al., 2001; Hayama ...

Cucumbers (Cucumis sativus) are known for their plasticity in sex expression. DNA methylation status determines gene activity but is susceptible to environmental condition changes. Thus, DNA methylation-based epigenetic regulation may at least partially account for the instability of cucumber sex expression. Do temperature and photoperiod that are the two most important environmental factors have equal effect on cucumber sex expression by similar epigenetic regulation mechanism? To answer this question, we did a two-factor experiment of temperature and photoperiod and generated methylome and transcriptome data from cucumber shoot apices. The seasonal change in the femaleness of a cucumber core germplasm collection was investigated over five consecutive years. As a result, 71.3% of the 359 cucumber accessions significantly decreased their femaleness in early autumn when compared with spring. High temperature and long-day photoperiod treatments, which mimic early autumn conditions, are both unfavorable

Many plants are photoperiod sensitive and can measure day length changes to forecast the change in seasons and react accordingly. As a result, photoperiod sensitive plants will synchronize flowering time as a result of changes in day length, and the degree of sensitivity may change at different points in the developmental life cycle of the plant.. Many domesticated plants have lost their photoperiod sensitivity during the domestication process with a focused breeding effort giving farmers predictable plant life cycles they can rely on to ensure multiple harvests and consistent flowering times for a population. During recent domestication, and breeding steps, mutations in the genes that encoded the light sensing mechanism were introduced or incorporated as a result of crossbreeding with natural occurring autoflowering plants within the same species that eliminate the photoperiod sensitivity resulting in photoperiod insensitive plant.. Today, cannabis and hemp are being actively bred for ...

Photoperiodic regulation of pituitary thyroid-stimulating hormone and brain deiodinase in Atlantic salmonPhotoperiodic regulation of pituitary thyroid-stimulating hormone and brain deiodinase in Atlantic salmon
Seasonal timing is important for many critical life history events of vertebrates, and photoperiod is often used as a reliable seasonal cue. In mammals and birds, it has been established that a photoperiod-driven seasonal clock resides in the brain and pituitary, and is driven by increased levels of pituitary thyroid stimulating hormone (TSH) and brain type 2 iodothyronine deiodinase (DIO2), which leads to local increases in triiodothyronine (T3). In order to determine if a similar mechanism occurs in fish, we conducted photoperiod manipulations in anadromous (migratory) Atlantic salmon (Salmo salar) that use photoperiod to time the preparatory development of salinity tolerance which accompanies downstream migration in spring. Changing daylength from short days (light:dark (LD) 10:14) to long days (LD 16:8) for 20 days increased gill Na+/K+-ATPase (NKA) activity, gill NKAα1b abundance and plasma growth hormone (GH) levels that normally accompany increased...

Although there is much theoretical and empirical data about the life history responses of time constrained organisms, little is known about the latitude compensating mechanism that enables northern populations developmental rates to compensate for latitude. To investigate the importance of photoperiod on development and growth, I collected adults and raised the offspring of the obligatory univoltine damselfly Lestes sponsa from two populations at different latitudes (53º N and 63º N). The offspring were raised in a common laboratory environment at 21º C and at the two photoperiods corresponding to the sites of collection. Field data showed that adult and egg sizes decreased towards the higher latitude. This adult size difference was a genetically fixed trait since the same size difference between populations was also found when larvae where reared in the laboratory. All studied individuals expressed shorter development time and faster growth rates under northern photoperiod regimes. Northern ...

Day Neutral Flowering represses Constans to prevent Arabidopsis flowering early in short days - WRAP: Warwick Research Archive...Day Neutral Flowering represses Constans to prevent Arabidopsis flowering early in short days - WRAP: Warwick Research Archive...
The photoperiodic response in Arabidopsis thaliana requires the precise regulation of CONSTANS (CO) expression in relation to the light period during the day. In short days (SDs) levels of CO expression are normally low during the light period, and this results in delayed flowering compared with long days (LDs) when CO expression rises to high levels before the end of the light period. We identified a novel flowering time gene called DAY NEUTRAL FLOWERING (DNF) that acts in the same flowering pathway as CO. DNF is a membrane-bound E3 ligase that represses CO expression and plays an important role in maintaining low levels of CO expression in SDs. The effect of DNF on the rhythm of CO expression is essential for the photoperiodic response of Arabidopsis, enabling it to have a different flowering response in LDs and SDs.. ...

Soybean Planting Decision Tool
For a detailed description of how the model calculates and predicts crop stages as well as the parameter values used in this decision tool see Archontoulis et al. (2014). Briefly, the APSIM-soybean model (Robertson et al., 2002; Keating et al., 2003) divides the soybean crop cycle into seven major phases and uses a thermal time methodology modified by photoperiod to define growth phase targets. Air temperature and photoperiod (length of daylight) are the main drivers of soybean phenology. Calculation of thermal time in the model uses a 3-hour interpolation method and a specified temperature/thermal time relationship. The base temperature for development is 50۶ (10۳), the optimum is 86۶ (30۳) and the maximum is 104۶ (40۳). These parameters are generic for all cultivars. In contrast, the parameters describing photoperiod effects (critical [12.5-14.5 hours] and photoperiod sensitivity [0.15-0.30 hour-1]) are cultivar specific. The longer the maturity group, the more sensitive to photoperiod ...

The plant flowering process represents the transition from vegetative to productive growth, and is controlled by complicated innergenetic regulation and the external environment. Flowering is closely related to the heading date and maturity crops, and has been studied for hundreds of years [1]. Currently, studies on Arabidopsis thaliana have revealed five pathways, the vernalization, photoperiod, gibberellin, autonomous, and endogenous pathways [1]. Initially, it was discovered that day length, namely photoperiod, could be perceived by higher plants and impacted their flowering. Over these years, different models have been put forward to explain the relationship between flowering and photoperiod [2,3]. Recently, a growing number of genes have been characterized as effectors of the natural condition or internal regulatory network, which has enhanced our knowledge of the regulators mediating the flowering pathway and plant circadian clock.. In the study of A. thaliana, a long-day model plant, ...

Red firespike (Odontonema strictum) is a tropical flowering plant that was selected as a potential flowering potted plant for its attractive red floral spikes. The objective of this study was to evaluate how light intensity, photoperiod, and temperature affect the growth and flowering of firespike. In Experiment 1, plants were grown under 0%, 45%, or 65% shade and two photoperiod conditions; long-day (LD = ≥14 h) and short-day (SD = 9 h), for 16 weeks. Plants grown under 45% shade + LD were tallest at 35.9 cm, while plants grown under 65% shade + SD were shortest at 22.8 cm. During the finishing stage, the number of inflorescences increased when plants were grown under 45% shade + SD, 45% shade + LD, and no shade, with 6, 7, and 9 inflorescences, respectively. In addition, the first open flower was observed in the 0% shade group (control) 92 days after starting the experiment. The time to first open flower increased when the plants were grown under 65% shade, either under SD or LD. In Experiment 2,

Reduced height 8 (Rht8) is the main alternative to the GA-insensitive Rht alleles in hot and dry environments where it reduces plant height without yield penalty. The potential of Rht8 in northern-European wheat breeding remains unclear, since the close linkage with the photoperiod-insensitive allele Ppd-D1a is unfavourable in the relatively cool summers. In the present study, two near-isogenic lines (NILs) contrasting for the Rht8/tall allele from Mara in a UK-adapted and photoperiod-sensitive wheat variety were evaluated in trials with varying nitrogen fertiliser (N) treatments and water regimes across sites in the UK and Spain.. The Rht8 introgression was associated with a robust height reduction of 11% regardless of N treatment and water regime and the Rht8 NIL was more resistant to root-lodging at agronomically-relevant N levels than the tall NIL. In the UK with reduced solar radiation over the growing season than the site in Spain, the Rht8 NIL showed a 10% yield penalty at standard ...

Dear Netters, Thank you for the wonderful response (I had over 10). This is a summary and conclusion of the response plus my investigation of most of the references. To start with I must clarify my objectives a little better than I did in my first message. I am a physiologist interested in characterizing growth responses to different environmental stresses. Since Arabidopsis is so small I was looking for conditions that would optimize growth conditions to produce the greatest amount of leaf biomass for analyses. (I think there might be a few people out there who might also be interested in this). I have found that growing plants hydroponically is by far the best way to get big plants (no root restriction, well-watered all the time, ample nutrient supply). We are also interested in delaying flowering to get larger plants. We are using both the Columbia and Ler ecotypes (hence my interest in photoperiod). Shorter days delay flowering in our two ecotypes and produce much larger plants before ...

In humans, changes in day length, shift-work or trans-meridian travel lead to deficits in mood and cognitive functions. Previously, these deficits were thought to arise exclusively from sleep deprivation and/or disruptions in circadian rhythms. Work from Dr. Samer Hattars laboratory has recently shown that light can directly affect mood and learning, even in the context of normal sleep and functional circadian activity. The goal of our project is to determine the retinal and brain circuits that underlie the effects of an aberrant light schedule on mood and cognitive functions, by employing a combination of anatomical, functional, and behavioral approaches. We will evaluate the effects of social and sensory stimulations as possible therapies to prevent the mood and learning deficits induced in mice exposed to aberrant light schedules.

The most dramatic phase change that flowering plants undergo is the transition from vegetative to reproductive growth. For this transition to be successful, plants must integrate a variety of environmental signals with endogenous cues, such as plant age (Bernier, 1988).. In the facultative long-day plant Arabidopsis, the transition to reproductive growth occurs rapidly in long days but much more slowly in short days. Several flowering-time mutants, in which the timing of this transition is changed, have been isolated. Analysis of the responses of different mutants to the environment together with studies of their genetic interactions have resulted in a two-pathway model showing how the transition to flowering is regulated (Martínez-Zapater et al., 1994; Weigel, 1995; Peeters and Koornneef, 1996). According to this model, long days induce flowering via a facultative and fast pathway, whereas under noninductive photoperiods, an autonomous and much slower pathway is rate limiting. The latter ...

VATIS Update Biotechnology . May-Jun 2006 - Techmonitor
The Umea Plant Centre scientists also looked at the genetics that signal fall growth cessation and bud set in trees. They discovered that CO accumulates in response to long days and initiates the formation of FT, and in the short days of fall, the pattern of CO accumulation changes so that FT is not activated. They also observed that the same species of tree at different latitudes would respond to local conditions in order to become dormant before the risk of frost damage. Because the short day-lengths occurring in fall induce bud set, the scientists wondered if FT and CO also controlled this process. When they grew trees originating from different latitudes in Europe in a growth chamber, the Umea Plant Centre team observed that this response was under strong genetic control and was maintained when trees were moved. However, they did observe that levels of CO and FT genes could be made to respond to artificially imposed day-length. Most importantly, they observed that under the same day-length, ...

Neuromuscular synaptic transmission in the ectothermal crab Carcinus maenas was used to assess the extent to which photoperiod affected the attainment of temperature acclimation. A separate series of experiments were carried out to determine thermotolerance to high temperature (CTMax) and its dependence on prior heat shock and heat shock proteins. Dactylopodite closer muscle resting potentials and the characteristics of evoked excitatory junction potentials in response to stimulation of the excitatory tonic axon were recorded with intracellular microelectrodes and the extent of acclimation to temperature under different photoperiodic regimes was measured. Animals were acclimated for at least two week to either 8 C or 25 C with short day (8hr: 16hr, L/D) or long day (16hr: 8hr, L/D) photoperiods. Photoperiod differences had a marked effect on acclimation to temperature as measured by muscle resting potential and excitatory junction potential amplitude and facilitation. In short day photoperiods ...

The capacity to develop tolerance to photoinhibition of photosynthesis was assessed in jack pine seedlings (Pinus banksiana Lamb.). Photoinhibition induced at 5 degrees C in control jack pine seedlings grown at 20 degrees C was saturated above an irradiance of 1000 mu mol . m(-2). s(-1) but was detectable at an irradiance as low as 25 mu mol . m(-2). s(-1). However, 20 degrees C seedlings shifted to 5 degrees C were 2-fold more tolerant to photoinhibition than 20 degrees C unshifted control seedlings, as detected by either the light-dependent decrease in photochemical efficiency or the apparent quantum yield of O-2 evolution. The extent of this tolerance of photoinhibition was dependent upon time, photoperiod, and irradiance during exposure to the low-temperature shift. Furthermore, the tolerance of photoinhibition was correlated with anthocyanin accumulation in 20 degrees C grown seedlings shifted to 5 degrees C. In addition, seedlings shifted to 5 degrees C and an 8-h photoperiod exhibited a ...

Failure to respond to endogenous or exogenous melatonin may cause nonphotoresponsiveness in Harlan Sprague Dawley ratsFailure to respond to endogenous or exogenous melatonin may cause nonphotoresponsiveness in Harlan Sprague Dawley rats
Responsiveness of the reproductive system, metabolic rate, and other traits to changing photoperiods from summer to winter seasons is an important physiological trait in most temperate-zone mammals [1]. Seasonal changes in photoperiod, or day length, modify reproductive timing in many temperate-zone mammals including sheep, hamsters, rodents, horses, and ferrets by acting through the photoperiod pathway [2 - 4]. The photoperiod pathway transduces the photoperiod into a physiological signal beginning with the transduction of light or dark input from specialized photoreceptors and ganglion cells in the eye through the retinohypothalamic tract into two regions of the hypothalamus, the suprachiasmatic nucleus (SCN), and later the paraventricular nucleus. A sympathetic norepinephrine signal from the SCN then passes to the hindbrain, the superior cervical ganglion in the spinal cord, and eventually to the pineal gland, which releases the indoleamine hormone melatonin [5]. Pinealoctyes within the ...

The project has three phases: In the first phase, chickpea genotypes were evaluated in the growth chambers for their flowering response under both long (16 h) and short days (10 h) and 22 0C and 16 0C day and night temperatures. Variability among the genotypes in their flowering response under either long or short days was identified. In the second phase of the study eight selected chickpea genotypes with extreme responses to photoperiod will be evaluated to determine the timing and duration of the photoperiod sensitive phase and the time of floral initiation and to establish whether photoperiod sensitivity ends at floral initiation or if it extends further into the phases of flower development. These same eight genotypes will be further characterized in a factorial combination of two photoperiods: 10 h and 16 h and three temperatures regimes: 16/8 0C, 20/12 0C and 24/16 0C (day/night).

These same eight genotypes will be further characterized in a factorial combination of two photoperiods: 10 h and 16 h and three temperatures regimes: 16/8 0C, 20/12 0C and 24/16 0C (day/night). This study allows us to determine flowering response of chickpea genotypes grown in a range of thermal regimes ...

DIGITAL.CSIC: Identification and phylogenetic analysis of FT genes in common bean (Phaseolus vulgaris L.)DIGITAL.CSIC: Identification and phylogenetic analysis of FT genes in common bean (Phaseolus vulgaris L.)
Flowering in many plant species is controlled by photoperiod, which represents the most reliable seasonal change in nature. The availability of crops with different photoperiod responses made it possible to extend their distribution range. The gene network controlling flowering is well studied in the model plant Arabidopsis thaliana, where the FLOWERING LOCUS T (FT) gene is crucial for the acceleration of flowering. FT is part of a gene family that also includes the TERMINAL FLOWER 1 (TFL1) gene, which inhibits flowering. Constitutive FT expression or loss of TFL1 function causes early flowering and transition of the shoot apex from vegetative to reproductive identity. FT proteins have a conserved role as mobile flowering signals in several different species and promote flowering in long or short days depending on the species. The induction of flowering by FT family members has been investigated in legumes such as pea, soybean and Medicago but the FT family has not yet been characterized in ...

Do Photoperiodic Changes in Melatonin Secretion Detrimentally Affect t by Riki SzlafrokDo Photoperiodic Changes in Melatonin Secretion Detrimentally Affect t by Riki Szlafrok
Melatonin, better known as the hormone of darkness, is secreted by the pineal gland during the night and helps us fall asleep. Because its internal regulation depends on light, melatonin is part of chronobiology, the study of biological mechanisms and their adaptations to lunar and solar related rhythms (Klein et al. 1991). Therefore, photoperiod changes greatly impact melatonin concentration, influencing changes in neuronal and hormonal mechanisms of the photo neuro-endocrine systems, namely reproduction. Research has shown that a disruption in the circadian rhythm of melatonin due to photoperiod changes detrimentally affects the rhythmic function of the female reproductive cycle. Research from journals, articles, and printed books has shown that both exogenous and endogenous features contribute to the reproductive cycle and that the internal mechanisms are entrained by environmental cues. Photoresponsiveness of the reproductive system is mediated by the internal biological clock, transcriptional

337S is a novel bi-pole-photo-thermo-sensitive genic male sterile line in wheat, and sensitive to both long day length/high temperature and short day length/low temperature condition. Although the regulatory function of MicroRNAs (miRNAs) in reproductive development has been increasingly studied, their roles in pre-meiotic and meiotic cells formation of plants have not been clearly explored. Here, we explored the roles of miRNAs in regulating male sterility of 337S at short day length/low temperature condition. Small RNA sequencing and degradome analyses were employed to identify miRNAs and their targets in the 337S whose meiotic cells collapsed rapidly during male meiotic prophase, resulting in failure of meiosis at SL condition. A total of 102 unique miRNAs were detected. Noticeably, the largest miRNA family was MiR1122. The target CCR4-associated factor 1 (CAF1) of miR2275, a subunit of the Carbon Catabolite Repressed 4-Negative on TATA-less (CCR4-NOT) complex, contributes to the process of early

To ensure reproductive success, flowering time is sophisticatedly regulated by developmental processes that integrate various external and internal factors in plant. Recent studies showed that post-transcriptional control also plays important roles in flowering time regulation (Bezerra et al., 2004; Doyle et al., 2005; Kuhn et al., 2007; Liu et al., 2007b). In our study, AtBRNs regulate the flowering time through the post-transcriptional control of SOC1 activity. The atbrn1/atbrn2-3 double mutant flowered early under LD and SD conditions, and under SD conditions after vernalization treatment (Fig. 2a), and the early-flowering phenotype was associated with increased expression of AP1, LFY, and FT. Although these integrators have overlapping functions, SOC1 definitely regulates LFY expression (Lee & Lee, 2010). Consistently, the LFY transcript showed the highest rate of increase in these integrators. SOC1 RNA, which is not regulated by AtBRNs, could activate LFY expression in atbrn1/atbrn2-3. ...

CONSTANS is a photoperiod regulated activator of flowering in sorghum | BMC Plant Biology | Full TextCONSTANS is a photoperiod regulated activator of flowering in sorghum | BMC Plant Biology | Full Text
The results indicate that there has been a significant change in the complement of FT-like genes that function as the main sources of florigen in sorghum (SbCN8, SbCN12) and rice (Hd3a = SbCN15; RFT1, no sorghum ortholog), therefore regulation of flowering time could also differ, even though both grass species are short day plants. SbCO activates expression of SbCN8 and SbCN12, although SbCN12 was induced to a significantly greater extent. SbCO also increased expression of SbEHD1, an activator of Hd3a expression in rice. SbEHD1 expression is repressed by SbPRR37 and SbGhd7 and induced when photoperiod sensitive sorghum grown in LD is transferred to SD [1, 2]. Increases in SbEHD1 expression occur in parallel with increases in SbCN8 and SbCN12 expression, suggesting that SbEhd1 can induce the expression of these genes as shown in Figure 6. However, the extent and specificity of this proposed activity of SbEhd1 will require further analysis in backgrounds where SbCO has minimal influence on the ...

Hormonal control of the gonadal regression and recovery observed in short days in male and female doves. - Balthazart JacquesHormonal control of the gonadal regression and recovery observed in short days in male and female doves. - Balthazart Jacques
en] Sexually mature ring doves (Streptopelia risoria) maintained from hatch on a photoperiod of 14 h light : 10 h darkness (14L : 10D) and kept in isolation were transferred to 8L : 16D. This treatment resulted in a partial regression of the ovaries and testes and a fall in the concentration of plasma LH but not of plasma FSH. After 2--3 months exposure to 8L : 16D, the gonads regrew to their original size: this regrowth was accompanied by a parallel increase in the concentration of plasma LH. The responsiveness of the pituitary gland to LH releasing hormone in both sexes after 5 weeks of exposure to 8L : 16D (when the gonads were partially regressed) was similar to the response observed after 15 weeks exposure to this lighting schedule (when the gonads had regrown). It was concluded that the spontaneous recovery of gonadal size in ring doves exposed to 8L : 16D is controlled by the hypothalamus and does not involve changes in the functional capacity of the pituitary gland or of the gonads ...

Drosophila melanogaster, like most organisms, has an endogenous clock. This clock is mainly synchronized by light. To achieve this, D. melanogaster uses three photoreceptor organs: the compound eyes, the ocelli and the Hofbauer Buchner eyelet. Additionally, the fly has the blue light photoreceptor pigment chryptochrome and an unknown photoreceptor pigment in the dorsal neurons of the endogenous clock. To test the influence of those photoreceptors and pigments on the endogenous clock, the locomotor activity of various fly strains was recorded under long- and short-day conditions. This investigation revealed that cryptochrome is particularly important for the entrainment in short photoperiods. It mediates the after-effects of light on the endogenous clock, and it is responsible for period lengthening in long day scenarios. The compound eyes are important for the entrainment under short- and long-day conditions, yet more so in long days. Furthermore, they are responsible for the adjustment of the ...

Think Fast - Dutch Passion - Freedom SeedsThink Fast - Dutch Passion - Freedom Seeds
Dutch Passion are proud to present the non-autoflowering version of the legendary Think Different. Think Fast was created by crossing Think Different AutoFem with a specially selected cutting of the Dutch Passion classic Power Plant in the search of new AutoFem genetics. The first generation offspring, which is normally used for further breeding, was let flowering and gave surprisingly good results. When crossing an autoflowering variety with a traditional photoperiod variety, none of this offspring will be autoflowering. The Dutch Passion geneticists discovered that these non autoflowering plants, which carry the recessive autoflowering gene are significantly faster than their photoperiod parents. Think Fast still needs a 12/12 light system to start flowering, but grows bigger and taller in a faster way. With this feature it becomes possible to grow big, potent, photoperiod strains with almost the speed of an autoflower. Think Fast can be grown outdoors and indoors and will reach the height of ...

An indoor screening method for reduced fall dormancy in alfalfa - Agriculture and Agri-Food Canada (AAFC)An indoor screening method for reduced fall dormancy in alfalfa - Agriculture and Agri-Food Canada (AAFC)
Fall dormancy is a determinant factor of alfalfa yield in northern climate but selection for that trait is often done to the detriment of freezing tolerance. Selection for low dormancy in the field is a tedious process that depends on unpredictable fall conditions allowing the identification of less dormant genotypes. Here we describe two screening methods entirely performed indoor for the selection for low dormancy in alfalfa without negative impact of freezing tolerance. One method is for semi-dormant cultivars and includes successive freezing stress to simultaneously improve freezing tolerance and the other is for winterhardy dormant cultivars. In both approaches, alfalfa is exposed to a critical photoperiod during four weeks that allows to discriminate between dormant and less-dormant genotypes. These approaches can be used to generate recurrently selected populations that are progressively less dormant.. ...

Metamorphic adult development proceeds over 18 stages, each stage lasting 1-4 d, beginning at the time of pupation and ending with the emergence of the adult moth. Pupae were staged by the criteria described by Tolbert et al.

Thermal relations and molecular measures in salmonidae gene expressionThermal relations and molecular measures in salmonidae gene expression
Arctic, boreal and temperate latitudes are characterised by conspicuous shifts in photoperiod and temperature, which restricts ecosystem productivity and compels resident taxa to anticipate and coordinate physiological processes to the cyclic variability of environmental conditions. The increase in temperature of high latitude habitats due to climate change is likewise complicit in asserting a progressive phenological incongruence between photoperiod and temperature, the repercussions of which on circadian and seasonal rhythms remain veiled in uncertainty. An organisms capacity to physiologically adjust to a changing environment relies upon the induction of gene expression programmes quantifiable through steady-state mRNA level, which has long served as a proxy for transcription and functional inferences in ecophysiological studies, although it is ultimately determined by the integrated processes of nuclear transcription and nucleocytoplasmic degradation. There is consequently an inadequate ...

The distribution of responses to the question Why do you have sex at these times? is shown in Figure 2. Although the subjects were allowed to give multiple answers, most of them gave only one answer, and the few who chose Other actually wrote in one the four offered options. Consequently, the percentages of answers conveniently added up to 100%. Only 28% of the respondents gave an answer that would characterize an endogenous rhythm of sexual appetite (I feel more sexual at these times). In contrast, 33% of the respondents attributed the time selection to restrictions imposed by work/family schedule, and 23% attributed it to partner availability. The distribution of percentages does not differ significantly from a flat distribution (D = 0.090, p , 0.05), which indicates that none of the four responses was consistently chosen more frequently than the others. Thus, the response based on an endogenous rhythm of sexual appetite was chosen by only a quarter of the respondents. Even this ...

Three groups of genes, Vrn, Ppd and Eps, control life-cycle duration in wheat (Triticum aestivum L.). The duration of a developmental phase between two stages is important for freezing resistance, heading time, anthesis and ripening date as well as yield component generation. The aim of the current study was to assess the effect of Vrn-D1 on wheat development. The vernalization genes Vrn-A1, -B1, -D1, -B3, photoperiod gene Ppd-1 and candidate genes Mot1 and FtsH4 for Eps in G883, Pumai 9 and their offspring, a group of sister lines (SLs) derived from an advanced generation, were genotyped using specific molecular markers. All detected loci were the same in the SLs and their parents except the Vrn-D1 locus.
