Regulation of 2-carboxy-D-arabinitol 1-phosphate phosphatase: activation by glutathione and interaction with thiol reagents. (1/9955)

2-Carboxy-D-arabinitol 1-phosphate (CA1P) phosphatase de- grades CA1P, an inhibitor associated with the regulation of ribulose bisphosphate carboxylase/oxygenase in numerous plant species. CA1P phosphatase purified from Phaseolus vulgaris was partially inactivated by oxidizing conditions during dialysis in air-equilibrated buffer. Phosphatase activity could then be stimulated 1.3-fold by dithiothreitol and also by addition of reduced thioredoxin from Escherichia coli. These effects were enhanced synergistically by the positive effector, fructose 1, 6-bisphosphate (FBP). Most notably, CA1P phosphatase activity was stimulated up to 35-fold by glutathione, and was sensitive to the ratio of reduced (GSH) to oxidized (GSSG) forms. At concentrations of glutathione approximating measured levels in chloroplasts of P. vulgaris (5 mM total S), CA1P phosphatase exhibited >20-fold stimulation by a change in the redox status of glutathione from 60 to 100% GSH. This stimulation was augmented further by reduced E. coli thioredoxin. In contrast, FBP, which activates CA1P phosphatase under reducing conditions, was strongly inhibitory in the presence of GSSG. We propose that glutathione may have an appreciable role in the light/dark regulation of CA1P phosphatase in vivo. A model for the reversible activation of CA1P phosphatase by GSH was derived based upon the various responses of the enzyme's activity to a range of thiol reagents including N-ethylmaleimide, 5, 5'-dithiobis-(2-nitrobenzoic acid) and arsenite. These data indicate that the bean enzyme contains two physically distinct sets of thiol groups that are critical to its redox regulation.  (+info)

The localisation of 2-carboxy-D-arabinitol 1-phosphate and inhibition of Rubisco in leaves of Phaseolus vulgaris L. (2/9955)

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)

The internal Cys-207 of sorghum leaf NADP-malate dehydrogenase can form mixed disulphides with thioredoxin. (3/9955)

The role of the internal Cys-207 of sorghum NADP-malate dehydrogenase (NADP-MDH) in the activation of the enzyme has been investigated through the examination of the ability of this residue to form mixed disulphides with thioredoxin mutated at either of its two active-site cysteines. The h-type Chlamydomonas thioredoxin was used, because it has no additional cysteines in the primary sequence besides the active-site cysteines. Both thioredoxin mutants proved equally efficient in forming mixed disulphides with an NADP-MDH devoid of its N-terminal bridge either by truncation, or by mutation of its N-terminal cysteines. They were poorly efficient with the more compact WT oxidised NADP-MDH. Upon mutation of Cys-207, no mixed disulphide could be formed, showing that this cysteine is the only one, among the four internal cysteines, which can form mixed disulphides with thioredoxin. These experiments confirm that the opening of the N-terminal disulphide loosens the interaction between subunits, making Cys-207, located at the dimer contact area, more accessible.  (+info)

Thiol-dependent degradation of protoporphyrin IX by plant peroxidases. (4/9955)

Protoporphyrin IX (PP) is the last porphyrin intermediate in common between heme and chlorophyll biosynthesis. This pigment normally does not accumulate in plants because its highly photodynamic nature makes it toxic. While the steps leading to heme and chlorophylls are well characterized, relatively little is known of the metabolic fate of excess PP in plants. We have discovered that plant peroxidases can rapidly degrade this pigment in the presence of thiol-containing substrates such as glutathione and cysteine. This thiol-dependent degradation of PP by horseradish peroxidase consumes oxygen and is inhibited by ascorbic acid.  (+info)

Expression of alfalfa mosaic virus coat protein in tobacco mosaic virus (TMV) deficient in the production of its native coat protein supports long-distance movement of a chimeric TMV. (5/9955)

Alfalfa mosaic virus (AlMV) coat protein is involved in systemic infection of host plants, and a specific mutation in this gene prevents the virus from moving into the upper uninoculated leaves. The coat protein also is required for different viral functions during early and late infection. To study the role of the coat protein in long-distance movement of AlMV independent of other vital functions during virus infection, we cloned the gene encoding the coat protein of AlMV into a tobacco mosaic virus (TMV)-based vector Av. This vector is deficient in long-distance movement and is limited to locally inoculated leaves because of the lack of native TMV coat protein. Expression of AlMV coat protein, directed by the subgenomic promoter of TMV coat protein in Av, supported systemic infection with the chimeric virus in Nicotiana benthamiana, Nicotiana tabacum MD609, and Spinacia oleracea. The host range of TMV was extended to include spinach as a permissive host. Here we report the alteration of a host range by incorporating genetic determinants from another virus.  (+info)

Cytokinin activation of Arabidopsis cell division through a D-type cyclin. (6/9955)

Cytokinins are plant hormones that regulate plant cell division. The D-type cyclin CycD3 was found to be elevated in a mutant of Arabidopsis with a high level of cytokinin and to be rapidly induced by cytokinin application in both cell cultures and whole plants. Constitutive expression of CycD3 in transgenic plants allowed induction and maintenance of cell division in the absence of exogenous cytokinin. Results suggest that cytokinin activates Arabidopsis cell division through induction of CycD3 at the G1-S cell cycle phase transition.  (+info)

Cloning and expression of a wheat (Triticum aestivum L.) phosphatidylserine synthase cDNA. Overexpression in plants alters the composition of phospholipids. (7/9955)

We describe the cloning of a wheat cDNA (TaPSS1) that encodes a phosphatidylserine synthase (PSS) and provides the first strong evidence for the existence of this enzyme in a higher eukaryotic cell. The cDNA was isolated on its ability to confer increased resistance to aluminum toxicity when expressed in yeast. The sequence of the predicted protein encoded by TaPSS1 shows homology to PSS from both yeast and bacteria but is distinct from the animal PSS enzymes that catalyze base-exchange reactions. In wheat, Southern blot analysis identified the presence of a small family of genes that cross-hybridized to TaPSS1, and Northern blots showed that aluminum induced TaPSS1 expression in root apices. Expression of TaPSS1 complemented the yeast cho1 mutant that lacks PSS activity and altered the phospholipid composition of wild type yeast, with the most marked effect being increased abundance of phosphatidylserine (PS). Arabidopsis thaliana leaves overexpressing TaPSS1 showed a marked enhancement in PSS activity, which was associated with increased biosynthesis of PS at the expense of both phosphatidylinositol and phosphatidylglycerol. Unlike mammalian cells where PS accumulation is tightly regulated even when the capacity for PS biosynthesis is increased, plant cells accumulated large amounts of PS when TaPSS1 was overexpressed. High levels of TaPSS1 expression in Arabidopsis and tobacco (Nicotiana tabacum) led to the appearance of necrotic lesions on leaves, which may have resulted from the excessive accumulation of PS. The cloning of TaPSS1 now provides evidence that the yeast pathway for PS synthesis exists in some plant tissues and provides a tool for understanding the pathways of phospholipid biosynthesis and their regulation in plants.  (+info)

Antisense expression of the CK2 alpha-subunit gene in Arabidopsis. Effects on light-regulated gene expression and plant growth. (8/9955)

The protein kinase CK2 (formerly casein kinase II) is thought to be involved in light-regulated gene expression in plants because of its ability to phosphorylate transcription factors that bind to the promoter regions of light-regulated genes in vitro. To address this possibility in vivo and to learn more about the potential physiological roles of CK2 in plants, we transformed Arabidopsis with an antisense construct of the CK2 alpha-subunit gene and investigated both morphological and molecular phenotypes. Antisense transformants had a smaller adult leaf size and showed increased expression of chs in darkness and of cab and rbcS after red-light treatment. The latter molecular phenotype implied that CK2 might serve as one of several negative and quantitative effectors in light-regulated gene expression. The possible mechanism of CK2 action and its involvement in the phytochrome signal transduction pathway are discussed.  (+info)

The dominant character of leaf size varies with different genetic models and leaf positions. In Model 1, the dominant characters of top and lower leaves are small size, but for the middle leaves it is large size. In Model 2, large size is dominant for three types of leaves. In Model 3, small size is dominant for the top and middle leaves, but recessive for lower leaves. In Model 4, small size is dominant in the top and lower leaves, but recessive in the middle leaves (Table 6). Therefore, we can not conclude and illustrate the inheritance of leaf size for tobacco leaves. Leaf size was determined by genetics and environment (Gurevitch, 1992); hence it may be suitable to illustrate the genetic mechanism for leaf size in a fixed position of single leaf, or increase the number of planted locations to increase the generational mean. This would allow us to estimate the effect of genetic-environmental interaction and understand the inheritance of leaf size.. Genetic Models and Inheritance of Leaf ...
Leaf abscission and foliation responses to water stress were studied in potted plants of five Populus clones grown in a greenhouse. As predawn leaf water potential (Ψ1) fell to -3 MPa, drought-induced leaf abscission increased progressively to 30% for data pooled across clones. As predawn Ψ1 fell below -3 MPa, drought-related abscission was about 50%. When combined with abscission rates in well-watered phenological control plants, abscission exceeded 80-90% in the most severely water-stressed plants. Clonal variation in water stress-induced abscission was statistically significant, but appeared to be confounded with clonal differences in leaf loss in control plants. Production of new leaf area ranged from 0 to 1,389 cm². Pooled across clones, maximum production of leaf area occurred in plants previously subjected to moderate water stress (-0.5 to -0.75 MPa). This stimulation of leaf development was associated with greater areas of individual leaves. At predawn Ψ1 < -2 MPa leaf area ...
The degree of photoinhibition of photosynthesis was compared between vertical (leaf angle 80° from the horizontal) and horizontal (leaf angle 0°) winter wheat ( Triticum aestivum ) leaves subjected to midday strong light stress under field conditions.This was done by measuring the PSⅡ photochemical efficiency (Fv/Fm) and the apparent quantum yield (AQY).On a clear day with maximum light level above 1600 μmol·m -2 ·s -1 and maximum leaf temperature 37.6℃,the Fv/Fm and AQY of the horizontal leaves were much lower than those of the vertical leaves after exposure to midday strong light for 4 hours,showing a more severe photoinhibition developed in horizontal leaves.Since the differences in leaf water potential and leaf temperature were negligible between horizontal and vertical leaves,the light intensity was the only factor causing difference in the degree of photoinhibition.On clear days with maximum leaf temperature 34.5℃,no difference in the extent of photoinhibition was observed
The fitness of the rape leaf is closely related to its biomass and photosynthesis. The study of leaf traits is significant for improving rape leaf production and optimizing crop management. Canopy structure and individual leaf traits are the major indicators of quality during the rape seedling stage. Differences in canopy structure reflect the influence of environmental factors such as water, sunlight and nutrient supply. The traits of individual rape leaves traits indicate the growth period of the rape as well as its canopy shape. We established a high-throughput stereo-imaging system for the reconstruction of the three-dimensional canopy structure of rape seedlings from which leaf area and plant height can be extracted. To evaluate the measurement accuracy of leaf area and plant height, 66 rape seedlings were randomly selected for automatic and destructive measurements. Compared with the manual measurements, the mean absolute percentage error of automatic leaf area and plant height measurements was 3

Automatic segmentation of plant leaves is vital for the detection of plant leaf diseases. In this research, we propose a novel framework for segmentation of plant leaf images using Improved Fast Fuzzy C Means Clustering and Adaptive Otsu threshold (IFFCM-AO) algorithm. In the proposed framework, initially, the plant leaf images are preprocessed using filtering and enhancement techniques. Image filtering is done for the removal of noise. In our work, we have proposed 2D Adaptive Anisotropic Diffusion Filter (2D AADF) for noise removal. Using these de-noised images, enhancement is done using Adaptive Mean Adjustment (AMA) technique. This step helps to intensify the region of interest in the image. Using the enhanced image, segmentation is performed by means of clustering and threshold. Clustering is done using the proposed Improved Fast Fuzzy C Means Clustering (IFFCMC) Algorithm and image threshold is performed using the proposed Adaptive Otsu (AO) threshold algorithm. The materials are collected in real
Plant leaves and their vascular patterns not only provide some of the most impressive examples of complexity in the nature that surrounds us, but they are also a wonderful system for studying developmental dynamics. In my talk I will focus on the development of leaf primary vein in the growing leaf primordia of Arabadopsis Thaliana, a plant model system. Leaf primary vein is the first in a successive order of branched veins, to emerge in a growing leaf primordia. The development of leaf primary vein starts with very few cells which also synthesize auxin, a growth hormone that regulates both plant and leaf vascular development. The final morphology of primary vein, consists of only a thin strand of distinctively elongated primary vein cells. I will present a cell based model, that describes the formation and morphology of leaf primary vein in early stages of growing leaf primordia. The model captures the interplay between biochemistry and cell mechanics by simulating the tissue growth driven by ...

This article aims at finding efficient hyperspectral indices for the estimation of forest sun leaf chlorophyll content (CHL, µg cmleaf− 2), sun leaf mass per area (LMA, gdry matter mleaf− 2), canopy leaf area index (LAI, m2leaf msoil− 2) and leaf canopy biomass (Bleaf, gdry matter msoil− 2). These parameters are useful inputs for forest ecosystem simulations at landscape scale. The method is based on the determination of the best vegetation indices (index form and wavelengths) using the radiative transfer model PROSAIL (formed by the newly-calibrated leaf reflectance model PROSPECT coupled with the multi-layer version of the canopy radiative transfer model SAIL). The results are tested on experimental measurements at both leaf and canopy scales. At the leaf scale, it is possible to estimate CHL with high precision using a two wavelength vegetation index after a simulation based calibration. At the leaf scale, the LMA is more difficult to estimate with indices. At the canopy scale, efficient
Chlorophyll fluorescence is a well established technique to rapidly and non-invasively determine photosynthesis parameters in plant leaves. It can be used in both laboratory and field settings, and frequently dark-adaptation of a leaf sample is called for. In the field, this can be accomplished on flat leaves using standard leaf clips supplied by instrument manufacturers. However, not all plant leaves are flat, many are cylindrical or otherwise three-dimensional in shape. The standard leaf clip does not close fully on three-dimensional leaves, therefore, does not allow the sample to be properly dark adapted in the field. A new leaf
Leaves are composed of a leaf blade, a broad flat structure that is specialized for photosynthesis, and a petiole, a stem-like structure that attaches the blade to the stem. A prominent feature of the leaf blade is its thick central midrib, which extends from the petiole and contains vascular tissues as well as enlarged supporting cells on the abaxial surface of the leaf. Surrounding the midrib is the lamina, which consists of patterned arrays of specialized cell types. Efforts in many labs to identify the molecules that are essential for normal leaf development are beginning to elucidate the pathways that are required for formation of a normal leaf, however, much information is still lacking.. Leaf primordia arise as radial pegs on the flank of the shoot apical meristem (SAM), and become flattened early in development, indicating acquisition of abaxial/adaxial polarity. These steps are rapidly followed by the outgrowth of the leaf blade and differentiation of specialized cell types (Pyke et ...

It will also act as a privacy screen when grown in a window box or on your window sill. ...
Abnormal yellowing of leaf tissue is called chlorosis. Leaves lack the essential green pigment chlorophyll. Possible causes include poor drainage, damaged roots, compacted roots, high soil pH, and nutrient deficiencies in the plant according to James Schuster University of Illinois Extension horticulture educator.. Nutrient deficiencies may occur due to insufficient amount in the soil or because the nutrients are unavailable due to high pH soil. Or nutrients may not be absorbed due to injured roots or poor root growth. Plant requirements also vary in the amount of 17 essential nutrients needed.. Herbaceous and woody plants are susceptible to chlorosis. It usually starts as lighter green tissue between darker green leaf veins.

When the autumn time comes, the most beautiful things in nature are the leaves! When leaves fall from the trees, everything around is painted with the gorgeous natural colors; yellow, red, orange, brown, crimson. Have you ever wondered if leaves are edible for some animals? Or maybe which tree leaves? In this article we will discuss whether guinea pigs can eat leaves, so please keep on reading.. Can guinea pigs eat leaves? Yes, guinea pigs can eat leaves but only certain types. This means they can eat leaves only from certain trees and branches. If you cannot identify the tree, it is best to avoid feeding the guinea pig an unidentified leaf. There are safe trees which can give the cavy some leaves to munch on. The most common leaves they can chew on are from the fruit trees. They can have apple, pear, willow, citrus tree, banana leaves, sunflower leaves pumpkin, mango, raspberry, grape, outer leaves of corn, cauliflower leaves, and mulberry too. Also, they can even have certain branches, such as ...
The organelles which contain chlorophyll, called plastids, need light in order to complete the synthesis and activation of chlorophyll, which together with other pigments then absorb most wavelengths of light excepting those in the green wave bands - this results in the light reflected from leaves being relatively enriched in green wavelengths and therefore appear to be green to us. In the absence of chlorophyll or another pigment light reflected off the surface of a leaf is not enriched in any particular wavelengths and thus appears to be white Or nearly so (often cream or pale yellow). Leaves can appear white when they lack a gene to synthesise the chlorophyll pigment, which may be apparent only in part of a so-called variegated leaf. Leaf miners which eat the chlorophyll-containing tissues inside a leaf may also leave white trails across the surface of a leaf. Lack of critical nutrients may prevent a leaf from making chlorophyll, which can result in a leaf with yellow or white blotches on it, ...

With so many leaves on a single tree it is inevitable that some will shade others. If a leaf is constantly shaded it will be discarded by the tree. If there is some sunlight however, even a little diffuse light (see below), then a tree makes the most of it by producing shade leaves lower down in its canopy. Shade leaves are larger and thinner than normal sun leaves, and often appear a darker green (they contain more chlorophyll). They also have half as many stomata than sun leaves, or even fewer, and so have a lower respiration rate. They can react quickly to brief bursts of sunlight and dappled shade.. Shade leaves can turn into sun leaves and visa versa; providing that the change is gradual. This is something that a gardener moving a plant outside that has been grown indoors or in the greenhouse, must be aware of. When a plant is taken outdoors, place it first under shade and gradually over several days increase its exposure to bright sunlight.. Trees are efficient in their architecture. Look ...
Leaves of seed plants can be described as simple, where the leaf blade is entire, or dissected, where the blade is divided into distinct leaflets. Both simple and dissected leaves are initiated at the flanks of a pluripotent structure termed the shoot apical meristem (SAM). In simple-leafed species, expression of class I KNOTTED1-like homeobox (KNOX) proteins is confined to the meristem while in many dissected leaf plants, including tomato, KNOX expression persists in leaf primordia. Elevation of KNOX expression in tomato leaves can result in increased leaflet number, indicating that tight regulation of KNOX expression may help define the degree of leaf dissection in this species. To test this hypothesis and understand the mechanisms controlling leaf dissection in tomato, we studied the clausa (clau) and tripinnate (tp) mutants both of which condition increased leaflet number phenotypes. We show that TRIPINNATE and CLAUSA act together, to restrict the expression level and domain of the KNOX genes Tkn1
Too much or too little water? The ruffled leaves, the birds nest shape, the interesting flowers, and its easy care, make it a must have for your next Instagram post. It is often said to be saprophytic on leaf litter so you can find it under trees often in the dark shade where nothing else will grow. Since it doesnt bear flowers, taking care of the foliage is of utmost importance. When overcrowded or stressed it often sends out a stalk of small, inconspicuous but very fragrant greenish/white, tan or yellow flowers. I did report it when I got it (didnt know that wasnt recommended…) A month has gone by, and the leaf opened up but now the very tip of the new leaf is turning black. Snake plant leaves turning yellow is usually an indication of a poor watering schedule, normally caused by overwatering but also just bad watering practises in general. Maybe you never knew there are many more anthuriums other than the ones you usually see with the red patent leather like spathes that are often ...
When choosing a hybrid and population for narrow rows, consider leaf architecture and ear type. There are essentially three types of leaves--upright, pendulum and semi-upright. · Upright-leaf hybrids grow straight up like a pineapple; in high populations an upright leaf structure lets sunlight reach deeper into the canopy, to increase photosynthesis. Upright leaves maximize photosynthesis when high populations are planted in narrow rows.. · Pendulum hybrid leaves are suited for lower populations, to decrease water loss by evaporation while maintaining photosynthetic activity. Pendulum-leaf hybrids flop out and intercept sunlight like solar panels, capturing light before it gets down low in the canopy. · Semi-upright hybrids have upper leaves that are more upright in structure and the lower leaves more pendulum.. Along with deciding which leaf architecture you need, look at ear type. Determinate-ear hybrids change their ear size very little, so you have to plant them at the higher end of the ...
Leaf morphology varies extensively among plant species and is under strong genetic control. Mutagenic screens in model systems have identified genes and established molecular mechanisms regulating leaf initiation, development, and shape. However, it is not known whether this diversity across plant species is related to naturally occurring variation at these genes. Quantitative trait locus (QTL) analysis has revealed a polygenic control for leaf shape variation in different species suggesting that loci discovered by mutagenesis may only explain part of the naturally occurring variation in leaf shape. Here we undertook a genetical genomics study in a poplar intersectional pseudo-backcross pedigree to identify genetic factors controlling leaf shape. The approach combined QTL discovery in a genetic linkage map anchored to the Populus trichocarpa reference genome sequence and transcriptome analysis. A major QTL for leaf lamina width and length:width ratio was identified in multiple experiments that confirmed
I love seeing leaf buds as they are about to burst from branches. Often they emerge in colors that identify a plant, like the yellow-gold of willows. For me buds symbolize the promise of life and timeless renewal, and the introduction of a new gardening season.. We all enjoy the shade of leaves above streets in summer, and the sound of wind rustling through a canopy of leaves, but you might not find leaves an exciting topic for many reasons. For the most part, they are green, although they come in different shades and tints. Many leaves shapes come in an uninspired oval, varying only in size. Leaves seem to be more concerned with function than aesthetics; a plain green leaf produces more food than a fancy-shaped variegated one. Leaves can cause work, too. Some leaves, as in lawns, need labor to make them attractive. Others need raking every autumn.. Yet to me, leaves are so much more.. Every leaf is a complicated chemical laboratory and manufacturing site, and the only one known to be capable ...
This BBC video clip introduces the role of stomata, with the surface structure of a leaf observed using increasingly larger magnifications.This can be used as an introduction to leaf structure and then developed into a discussion of the other features of a leaf and how it is adapted for efficient photosynthesis.
Although the leaves of different plants vary in their overall shape, most leaves are rather similar in their internal anatomy. Leaves generally consist of epidermal tissue on the upper and lower surfaces and mesophyll tissue throughout the body. Epidermal cells have two features that prevent the plant from losing water: they are packed densely together and they are covered by a cuticle (a waxy layer secreted by the cells). The epidermis usually consists of a single layer of cells, although the specialized leaves of some desert plants have epidermal layers that are several cells thick. The epidermis contains small pores called stomata, which are mostly found on the lower leaf surface. Each individual stoma (pore) is surrounded by a pair of specialized guard cells. In most species, the guard cells close their stomata during the night (and during times of drought) to prevent water loss. During the day, the guard cells open their stomata so they can take in carbon dioxide for photosynthesis and give ...
Most plant leaf damage caused by the recent frost is observed in fields with lighter soils, that were no-till, that had cover crops, and/or were along edges of waterways. Most plants are recovering with new leaves emerging, although the recovery process has been slower than I anticipated. With temperature forecasts in the 90s, new leaves should emerge. If new leaves do not appear, then the plant has died. This does not mean that the field must be replanted. Use decision guidelines from the UW publication, Corn replant/late-plant decisions in Wisconsin.. Although last weeks frost killed emerged corn leaves, the effect on yield will be negligible. By now, nearly a week after the frost, corn plants should be showing newly emerging leaves. There may be some tie-up of the leaves with the killed leaves, but eventually these newly emerged leaves will unfurl, and development will continue normally. Through the years we have done numerous leaf clipping studies where we have removed 100% of the leaves ...
IN THE GARDEN. Many gardeners like to leave a layer of fall leaves in their garden beds through winter because the leaves can act as a natural mulch. Like the mulch you would buy at a store, a layer of leaves can provide protection from harsh winter temperatures, with the added bonus of being full of beneficial compounds. However, you dont want to let the leaves pile on too thickly unless you plan on removing them in the spring, as they may end up smothering plants. A thick layer of leaves in the garden can also encourage pests to take up residence.. Tip: Raking in a garden bed can be a delicate operation-you dont want to pull up any of your precious bulbs! A leaf blower can help to get any leaves that are annoyingly ensnared in the stems and branches of your plants and shrubs out of the way.. AROUND THE HOME. Leaves that are allowed to collect on the creases of your roof or in your gutters can cause big issues later on, when rain and snow really start to come down. Stuck leaves and branches ...
This article was originally written as a guest post for The Paleo Mom: FROM NEW LEAF: This is a fantastically written article about T Helper 1 & 2 cells and how Auto-Immune is linked, which disorders are considered T Helper 1 or 2 dominant. All of which we treat at New Leaf Natural Therapies. Those that suffer from autoimmune disease commonly experience symptoms that stem from imbalances within the functioning of their immune system. There are many factors that can influence this balance - stress, nutrition, vitamin and mineral deficiencies, gut flora, and allergies, among others. This way of looking at autoimmune disease is a growing trend in the alternative field, highlighted through the work of Datis Kharrazian.. What are Th1 and Th2?. T-helper cells (abbreviated as Th) are a vital part of the immune system. They are lymphocytes (types of white blood cells) that recognize foreign pathogens, or in the case of autoimmune disease, normal tissue. In response to this recognition, they produce ...

In the fading twilight on the rainforest floor, a plants leaves glimmer iridescent blue. And now scientists know why. These exotic blue leaves pull more energy out of dim light than ordinary leaves because of an odd trick of quantum mechanics.. A team of plant scientists led by Heather Whitney of the University of Bristol in the U.K. has just discovered the remarkable origin and purpose of the shiny cobalt leaves on the Malaysian tropical plant Begonia pavonina. The plant owes its glimmer to its peculiar machinery for photosynthesis, the process plants use to turn light into chemical energy. Strangely enough, these blue leaves can squeeze more energy out of the red-green light that reaches the eternally dim rainforest floor. Whitney and her colleagues describe the blue leaves today in the journal Nature Plants.. ...
Recent work using sensitive techniques to measure leaf shape has suggested that directionalized asymmetry along the left and right side of the leaf may be more prevalent than once believed. Although superficially bilaterally symmetric, elliptical Fourier descriptor (EFD) analysis in Arabidopsis thaliana, in addition to simple measurements in the shifts between leaflet placement along the left and right sides of Solanum lycopersicum (tomato) leaves, reveals that plants in these species produce leaves biased to be left- or right-handed [5]. The asymmetry of leaves is dependent on the handedness of the plant from which they originate. Handedness in plants arises when the phyllotaxy (the angular arrangement of initiated leaves and other lateral organs on a plant) is spiral (i.e. the angle between initiating leaves is approximately the golden angle, approximately 137.5°). In reference to a bottom-up view of leaf initiation events, the spiral can form in two directions, either clockwise (C) or ...
As an important agronomic trait, rice (Oryza sativa L.) leaf rolling has attracted much attention from plant biologists and breeders. Moderate leaf rolling increases the photosynthesis of cultivars and hence raises grain yield. However, the relevant molecular mechanism remains unclear. Here, we show the isolation and functional characterization of SHALLOT-LIKE1 (SLL1), a key gene controlling rice leaf rolling. sll1 mutant plants have extremely incurved leaves due to the defective development of sclerenchymatous cells on the abaxial side. Defective development can be functionally rescued by expression of SLL1. SLL1 is transcribed in various tissues and accumulates in the abaxial epidermis throughout leaf development. SLL1 encodes a SHAQKYF class MYB family transcription factor belonging to the KANADI family. SLL1 deficiency leads to defective programmed cell death of abaxial mesophyll cells and suppresses the development of abaxial features. By contrast, enhanced SLL1 expression stimulates phloem ...
vii) A leaf has three main parts - Leaf base, petiole and leaf lamina. leaf which lifts the lamina above the level of the stem. The leaf is attached to the stem by the leaf base (hypo-podium) and may bear two lateral small leaf-like structures called stipules. When the veins run parallel to each other within a lamina, the venation is termed as parallel venation. In a whorled arrangement, three or more leaves connect at a node. Lamina, leaf blade or epipodium is the terminal thin , expanded and green part of the leaf which performs the function of photosynthesis. Simple Leaf- the lamina or the leaf blade is undivided. 0 votes.

Variation in morphological traits in evolution can be achieved by different routes, which include, but are not limited to, changes in a transcription factors expression pattern, biochemical properties (DNA binding properties or the ability to interact with other protein partners), and/or array of targets, either by recruitment of new targets, or loss of old targets. Currently, there is some debate surrounding the relative significance of cis-regulatory mutations versus mutations in coding regions of genes to drive morphological evolution (Hoekstra and Coyne, 2007; Wray, 2007). The data presented here hint that both mechanisms likely have been employed in the evolution of the KNOX1 and FLO/LFY pathways governing compound leaf development in the legumes.. We compared KNOX1 downregulation at the leaf initiation site in both early-diverging and more recently diverged clades in the Fabaceae and found that in all cases, including members of the IRLC, KNOX1 proteins are downregulated at P0. This ...
There are several species of bacteria that attack houseplants. Some of these bacterial infections become systemic throughout the plant while others will remain as localized lesions. Bacterial disease symptoms range from black to brown, often watery leaf spots or lesions to total collapse of the tissue. Collapsed tissues usually are soft and mushy with a rotten smell to them. Leaf symptoms will often be observed between the veins and may be contained between leaf veins and appear angular or V-shaped. Some plants will characteristically develop lesions along the leaf margins where the bacteria enter through hydathodes (small openings along the leaf margins). Often these infections will cause leaf drop. Other symptoms may include yellow margins around leaf lesions, small blister like spots that run together, or spots where the center falls out. ...

Changes in the patterns of ethylene production, chlorophyll content, and respiration were studied in relation to the senescence of intact leaves and leaf discs. The primary leaves of pinto bean, which abscise readily during natural senescence, and tobacco and sugar beet leaves, which do not abscise, were used. A decrease in the rate of ethylene production and respiration, during the slow phase of chlorophyll degradation, was observed in leaf-blade discs cut from mature leaves and aged in the dark. During rapid chlorophyll loss both ethylene production and respiration increased and then decreased. These climacteric-like patterns were shown by leaf discs of all three species. Discs taken from leaves that had been senescing on the plant also showed a climacteric-like rise in ethylene production but not in respiration, which decreased continuously with leaf age. Climacteric-like patterns in the rise of ethylene and respiration for leaf discs were also shown by the petioles of both bean and tobacco ...
Maize leaves skip neighbor plants by orientating their growth away from low R/FR signals. Under low R to FR ratios, eudicots tend to place their leaves in a more erect position in a movement articulated at the base of the petioles (Satter and Whetherell, 1968), and forage grasses place the entire shoot in a more erect position (Casal et al., 1990). We did not observe obvious changes in the angle of maize leaves on a vertical plane in response to R/FR signals simulating neighbor plants. In contrast, maize leaves showed a distinctive displacement of the lamina on the horizontal plane.. The shade avoidance syndrome (Smith, 2000) involves a series of changes in plant architecture in response to the low R to FR ratio of vegetation canopies, which improve the exposure of the foliage to photosynthetic light. Phytochrome-mediated changes include enhanced axis growth, reduced branching, organ reorientation, and accelerated flowering. The relative importance of these responses depends on the species. In ...
Yellowing leaves can indicate natural leaf drop (if it is just affected the oldest leaves), water stress, or disease such as black spot. Black spot is caused by Diplocarpon rosae, a fungus that overwinters on old diseased leaves and infected canes. Leaves are most susceptible while expanding. After fungal spores land on leaves, it takes at least 9 hours of leaf wetness for the spore to infect. Fungal fruiting bodies form in 11-30 days. A new crop of spores is produced and spreads to healthy portions of the plant by splashing rain or irrigation water. Spores do not survive in soil but do survive on all infected plant debris. The natural genetic variability of the fungus means roses found resistant in one location may be susceptible in another location due to the presence of different fungal strains. Also, resistant roses may become susceptible after a few years due to changes in the local fungal population. The symptoms of black spot begin with circular black spots, frequently with fringed ...

For a typical leaf, we use that of the umbrella tree, which is commonly sold as a foliage plant throughout North America and Europe. It is actually a tree native to tropical rainforests of northern Australia; it is a good example because we can examine it at any time of the year.. The structure of the umbrella tree leaf is typical of leaves in general (Above left photo). It has an outer layer, the epidermis, which produces a waxy waterproof coating. The epidermis of the undersurface produces guard cells, which swell and shrink to close and open the pores (stomata) which control the loss of water vapor (transpiration) and the entry of carbon dioxide. The internal tissues consist of the mesophyll, the photosynthetic cells of the leaf. These are typically the long columnar cells nearer the surface (palisade parenchyma) and the looser irregular cells beneath (the spongy mesophyll parenchyma). These cells are loaded with chloroplasts in the cytoplasm. Each of these cells has a large vacuole, bound by ...
