The reproductive cells of plants.
Symbiotic combination (dual organism) of the MYCELIUM of FUNGI with the roots of plants (PLANT ROOTS). The roots of almost all higher plants exhibit this mutually beneficial relationship, whereby the fungus supplies water and mineral salts to the plant, and the plant supplies CARBOHYDRATES to the fungus. There are two major types of mycorrhizae: ectomycorrhizae and endomycorrhizae.

Sexual dimorphism in white campion: complex control of carpel number is revealed by y chromosome deletions. (1/1066)

Sexual dimorphism in the dioecious plant white campion (Silene latifolia = Melandrium album) is under the control of two main regions on the Y chromosome. One such region, encoding the gynoecium-suppressing function (GSF), is responsible for the arrest of carpel initiation in male flowers. To generate chromosomal deletions, we used pollen irradiation in male plants to produce hermaphroditic mutants (bsx mutants) in which carpel development was restored. The mutants resulted from alterations in at least two GSF chromosomal regions, one autosomal and one located on the distal half of the (p)-arm of the Y chromosome. The two mutations affected carpel development independently, each mutation showing incomplete penetrance and variegation, albeit at significantly different levels. During successive meiotic generations, a progressive increase in penetrance and a reduction in variegation levels were observed and quantified at the level of the Y-linked GSF (GSF-Y). Possible mechanisms are proposed to explain the behavior of the bsx mutations: epigenetic regulation or/and second-site mutation of modifier genes. In addition, studies on the inheritance of the hermaphroditic trait showed that, unlike wild-type Y chromosomes, deleted Y chromosomes can be transmitted through both the male and the female lines. Altogether, these findings bring experimental support, on the one hand, to the existence on the Y chromosome of genic meiotic drive function(s) and, on the other hand, to models that consider that dioecy evolved through multiple mutation events. As such, the GSF is actually a system containing more than one locus and whose primary component is located on the Y chromosome.  (+info)

Sexual dimorphism in white campion: deletion on the Y chromosome results in a floral asexual phenotype. (2/1066)

White campion is a dioecious plant with heteromorphic X and Y sex chromosomes. In male plants, a filamentous structure replaces the pistil, while in female plants the stamens degenerate early in flower development. Asexual (asx) mutants, cumulating the two developmental defects that characterize the sexual dimorphism in this species, were produced by gamma ray irradiation of pollen and screening in the M1 generation. The mutants harbor a novel type of mutation affecting an early function in sporogenous/parietal cell differentiation within the anther. The function is called stamen-promoting function (SPF). The mutants are shown to result from interstitial deletions on the Y chromosome. We present evidence that such deletions tentatively cover the central domain on the (p)-arm of the Y chromosome (Y2 region). By comparing stamen development in wild-type female and asx mutant flowers we show that they share the same block in anther development, which results in the production of vestigial anthers. The data suggest that the SPF, a key function(s) controlling the sporogenous/parietal specialization in premeiotic anthers, is genuinely missing in females (XX constitution). We argue that this is the earliest function in the male program that is Y-linked and is likely responsible for "male dimorphism" (sexual dimorphism in the third floral whorl) in white campion. More generally, the reported results improve our knowledge of the structural and functional organization of the Y chromosome and favor the view that sex determination in this species results primarily from a trigger signal on the Y chromosome (Y1 region) that suppresses female development. The default state is therefore the ancestral hermaphroditic state.  (+info)

Male gametic cell-specific gene expression in flowering plants. (3/1066)

The role of the male gamete-the sperm cell-in the process of fertilization is to recognize, adhere to, and fuse with the female gamete. These highly specialized functions are expected to be controlled by activation of a unique set of genes. However, male gametic cells traditionally have been regarded as transcriptionally quiescent because of highly condensed chromatin and a very reduced amount of cytoplasm. Here, we provide evidence for male gamete-specific gene expression in flowering plants. We identified and characterized a gene, LGC1, which was shown to be expressed exclusively in the male gametic cells. The gene product of LGC1 was localized at the surface of male gametic cells, suggesting a possible role in sperm-egg interactions. These findings represent an important step toward defining the molecular mechanisms of male gamete development and the cellular processes involved in fertilization of flowering plants.  (+info)

The auxin-insensitive bodenlos mutation affects primary root formation and apical-basal patterning in the Arabidopsis embryo. (4/1066)

In Arabidopsis embryogenesis, the primary root meristem originates from descendants of both the apical and the basal daughter cell of the zygote. We have isolated a mutant of a new gene named BODENLOS (BDL) in which the primary root meristem is not formed whereas post-embryonic roots develop and bdl seedlings give rise to fertile adult plants. Some bdl seedlings lacked not only the root but also the hypocotyl, thus resembling monopteros (mp) seedlings. In addition, bdl seedlings were insensitive to the auxin analogue 2,4-D, as determined by comparison with auxin resistant1 (axr1) seedlings. bdl embryos deviated from normal development as early as the two-cell stage at which the apical daughter cell of the zygote had divided horizontally instead of vertically. Subsequently, the uppermost derivative of the basal daughter cell, which is normally destined to become the hypophysis, divided abnormally and failed to generate the quiescent centre of the root meristem and the central root cap. We also analysed double mutants. bdl mp embryos closely resembled the two single mutants, bdl and mp, at early stages, while bdl mp seedlings essentially consisted of hypocotyl but did form primary leaves. bdl axr1 embryos approached the mp phenotype at later stages, and bdl axr1 seedlings resembled mp seedlings. Our results suggest that BDL is involved in auxin-mediated processes of apical-basal patterning in the Arabidopsis embryo.  (+info)

The maize rough sheath2 gene and leaf development programs in monocot and dicot plants. (5/1066)

Leaves of higher plants develop in a sequential manner from the shoot apical meristem. Previously it was determined that perturbed leaf development in maize rough sheath2 (rs2) mutant plants results from ectopic expression of knotted1-like (knox) homeobox genes. Here, the rs2 gene sequence was found to be similar to the Antirrhinum PHANTASTICA (PHAN) gene sequence, which encodes a Myb-like transcription factor. RS2 and PHAN are both required to prevent the accumulation of knox gene products in maize and Antirrhinum leaves, respectively. However, rs2 and phan mutant phenotypes differ, highlighting fundamental differences in monocot and dicot leaf development programs.  (+info)

Evidence suggesting protein tyrosine phosphorylation in plants depends on the developmental conditions. (6/1066)

Protein tyrosine phosphorylation plays a central role in a variety of signal transduction pathways regulating animal cell growth and differentiation, but its relevance and role in plants are controversial and still largely unknown. We report here that a large number of proteins from all plant subcellular fractions are recognized by recombinant, highly specific, anti-phosphotyrosine antibodies. Protein tyrosine phosphorylation patterns vary among different adult plant tissues or somatic embryo stages and somatic embryogenesis is blocked in vivo by a cell-permeable tyrosyl-phosphorylation inhibitor, demonstrating the involvement of protein tyrosine phosphorylation in control of specific steps in plant development.  (+info)

RESPONSIVE-TO-ANTAGONIST1, a Menkes/Wilson disease-related copper transporter, is required for ethylene signaling in Arabidopsis. (7/1066)

Ethylene is an important regulator of plant growth. We identified an Arabidopsis mutant, responsive-to-antagonist1 (ran1), that shows ethylene phenotypes in response to treatment with trans-cyclooctene, a potent receptor antagonist. Genetic epistasis studies revealed an early requirement for RAN1 in the ethylene pathway. RAN1 was cloned and found to encode a protein with similarity to copper-transporting P-type ATPases, including the human Menkes/Wilson proteins and yeast Ccc2p. Expression of RAN1 complemented the defects of a ccc2delta mutant, demonstrating its function as a copper transporter. Transgenic CaMV 35S::RAN1 plants showed constitutive expression of ethylene responses, due to cosuppression of RAN1. These results provide an in planta demonstration that ethylene signaling requires copper and reveal that RAN1 acts by delivering copper to create functional hormone receptors.  (+info)

Characterization of homeodomain-leucine zipper genes in the fern Ceratopteris richardii and the evolution of the homeodomain-leucine zipper gene family in vascular plants. (8/1066)

The homeodomain-leucine zipper (HD-Zip) genes encode transcription factors that are characterized by the presence of both a homeodomain and a leucine zipper motif. They belong to the homeobox gene superfamily and have been reported only from flowering plants. This article is the first report on the ferm HD-Zip genes (named Crhb1-Crhb11) isolated from the homosporous ferm Ceratopteris richardii. Phylogenetic analyses of the II Crhb genes with previously reported angiosperm HD-Zip genes show that the Crhb genes belong to three of the four different angiosperm HD-Zip subfamilies (HD-Zip I, II, and IV), indicating that these subfamilies of HD-Zip genes originated before the diversification of the ferm and seed plant lineages. The Crhb4-Crhb8 and Crhb11 genes belong to the HD-Zip I subfamily but differ from angiosperm HD-Zip I genes by the presence of a seven-amino-acid indel in the leucine zipper motif. By the northern analyses, Crhb1 and Crhb3 were expressed only in gametophyte tissue. Expression of Crhb2 and Crhb11 genes could not be detected in any tissue examined, while all other Crhb genes were expressed in most sporophytic and gametophytic tissues. Although the functions of the Crhb genes in Ceratopteris are unknown, their patterns of expression suggest that they regulate developmental or physiological processes common to both the gametophyte and the sporophyte generations of the fern. Differences in the expression of Crhb1 between male gametophytes and male-hermaphrodite mixed populations of gametophytes suggests that the Crhb1 gene is involved in gametophytic sex determination.  (+info)

Phytostabilization has been advocated as a promising approach to reduce mine tailings adverse effects to surrounding environment. With many years of efforts in both laboratory and field trials, organic amendments are found to be essential in tailing revegetation. Yet, the associate geochemical dynamics caused by different amendments has rarely been examined. As reactive minerals are usually rich in tailings, geochemical changes induced by amendments would influence seepage management and revegetation strategies. The present study aimed to investigate geochemical dynamics in Cu-Au tailing leachate, in response to amendments with biochar produced from hardwood timber at high charring temperature or woodchips of mixed native tree species in a column leaching experiment under laboratory conditions. Results showed that the Cu-Au tailings tested in this study were relatively stable after natural weathering, with little resilience of peak salinity, stable pH and low levels of metals in leachate against the

To ensure evolutionary resilience under climate change, successful revegetation relies on capturing high levels of genetic diversity and thus adaptive potential. As the traditional use of exclusively local material is challenged, understanding species adaptation to climate will be critical for determining seed sources for robust revegetation into the future. In Australia, Eucalypts are a dominant species across many landscapes and are extensively used in revegetation. However, knowledge of genomics underlying adaptation is limited, with current genomic climate adaptation research in trees focusing predominantly on northern hemisphere species. Utilising the power of genomics, we employ DArTseq, a reducedrepresentation genomics approach, to investigate genomic diversity and adaptation in Eucalyptus microcarpa, an important revegetation species used extensively across agricultural south-eastern Australia. In particular we compare the genomics of natural stands to revegetated sites and fragmented ...

In both managed and natural ecosystems, beneficial plant-associated bacteria play a key role in supporting and/or increasing plant health and growth. Plant growth-promoting bacteria (PGPB) can be applied in agricultural production or for the phytoremediation of pollutants. However, because of their capacity to confer plant beneficial effects, efficient colonization of the plant environment is of utmost importance. The majority of plant-associated bacteria derives from the soil environment. They may migrate to the rhizosphere and subsequently the rhizoplane of their hosts before they are able to show beneficial effects. Some rhizoplane colonizing bacteria can also penetrate plant roots, and some strains may move to aerial plant parts, with a decreasing bacterial density in comparison to rhizosphere or ...
Our results suggest that extreme floods reduce riparian plant species richness in tranquil (slow-flowing) reaches but that a subsequent period of less extreme flood events facilitates recovery. Tranquil river reaches were also more prone to invasion by ruderal species following major floods. Species richness in turbulent reaches (rapids and runs) remained constant during all surveys. One possible explanation for this pattern is that tranquil reaches become more anoxic during floods because they have more fine-grade soils with lower hydraulic conductivity than turbulent reaches. Anoxic conditions may cause stress and plant death, opening up space for colonization. Turbulent reaches maintain a better oxygenation in the root zone of plants through high groundwater turnover, reducing negative effects of prolonged floods ...

Plant cover on landfills contributes to its landscape and assists in the reduction of leachate discharge through evapotranspiration. The latter function is particularly important if the landfill is not capped with an impermeable layer to control infiltration. Other benefits provided by the vegetation cover include visual improvement of the site, creation of wildlife habitat, and the sequestration of greenhouse gases. The species chosen for revegetation purpose depends on the afteruse of the site, climatic conditions, nursery stock availability, and hardiness of the species.. Despite the tremendous efforts and investment devoted to site engineering, the inclusion of a soil cover does not guarantee the successful establishment of vegetation. The depth and quality of the soil layer affect revegetation as a thicker soil cover is required for woody species which have deeper root systems.. Poor vegetation performance is a common feature of many old landfills. In the US, a nationwide survey conducted ...
Practitioners undertaking conservation activities, such as community groups, staff from government and non-government agencies and private landholders play a vital role in undertaking land management actions such as habitat restoration, including revegetating agricultural landscapes. Practitioners can also play an important role in learning how revegetated areas change over time by carrying out monitoring. Monitoring allows us to learn what actions are most effective in restoring vegetation to individual properties and whole landscapes, how well plant species survive and grow, and the quality of habitat it provides for faunal species. In the state of Victoria, Australia, practitioners worked alongside researchers to assess how effective revegetation outcomes are after the first year of planting. The monitoring aims were to assess the outcomes of revegetation, in terms of the survival of planted trees, shrubs and understory plants, and determine the factors that affect variation in survival among ...

In fact, they process information, sleep, remember, and signal to one another -- showing that, far from passive machines, plants are intelligent and aware. Through a survey of plant capabilities from sight and touch to communication, Mancuso challenges our notion of intelligence, presenting a vision of plant life that is more sophisticated than most imagine ...
We received a grant from the World Wide Fund for Nature in 2004 for a project Abating Threats to Spectacled Flying Foxes and their Mabi Habitat. Our partners included the Atherton Shire Council, TREAT, Mareeba Environmental College, Eacham Revegetation Unit, and BRICMA. The aim of the project was to plant 2 areas on the eastern side of the Tolga Scrub to limit edge effects and improve the integrity of this small fragment of forest. Providing a bushy edge to the Scrub and closing the canopy limits the effect of weeds and other invasive elements. Eacham Revegetation Unit dug the holes and students from the Mareeba Environmental College planted the trees.

The ever-increasing human population is a major concern for food security. Maize is the third largest most important food crop. The major problems of cultivation arise from urbanization and land pollution. This reduces the amount of land available for agriculture. The use of chemicals in agriculture is not environmentally friendly. Thus, plant growth-promoting bacteria (PGPB) have been proposed as alternatives. This study aims to test the growth-promoting effect of maize inoculated with six indigenous PGPB isolates. These isolates were assayed for various biochemical and plant growth-promoting activities. They were also assayed for biocontrol activities. Based on the results, six isolates viz A1, A18, A29, NWU4, NWU14, and NWU198 were used to inoculate maize seeds. The inoculated seeds were tried out on the field. A randomized block design was used. PGPB used were in single, consortia of two, and three organisms. The length of the leaves, roots, and stem, plant height, numbers of leaves, and weight of
The loss of coastal marshes is a topic of great concern, because these habitats provide tangible ecosystem services and are at risk from sea-level rise and human activities. In recent years, significant effort has gone into understanding and modeling the relationships between the biological and physical factors that contribute to marsh stability. Simulation-based process models suggest that marsh stability is the product of a complex feedback between sediment supply, flooding regime and vegetation response, resulting in elevation gains sufficient to match the combination of relative sea-level rise and losses from erosion. However, there have been few direct, empirical tests of these models, because long-term datasets that have captured sufficient numbers of marsh loss events in the context of a rigorous monitoring program are rare. We use a multi-year data set collected by the Coastwide Reference Monitoring System (CRMS) that includes transitions of monitored vegetation plots to open water to build...

The research teams studied mutants of the Arabidopsi leaf trichome, a specialized epidermal cell that forms a small hair-like outgrowth on plants. Unlike earlier studies, the teams focused on later stages in the trichome developmental process, which are accompanied by rapid cell growth and branching.. In their experiments, the researchers discovered that by disrupting the gene encoding a novel protein, GTL1, trichome cells could be induced to grow to twice their normal size, indicating that GTL1 represses cell growth. By measuring the amount of nuclear DNA in young trichomes, they further determined that GTL1, unlike previously-identified growth regulators, functions to suppress DNA reduplication and cell growth entirely at the very last stage of development.. ...

The winter grazing areas covered more than 800 ha in the lower altitudes (3 400 to 4 100 m) on southern (sunny) aspect slopes. Vegetation was dominated by a wide range of forbs and underwent a very marked cycle of growth and accumulation of biomass during the summer, and defoliation to ground level during the winter. Annual DM production was estimated to be between 1 500 and 3 500 kg/ha. Although the growing season extended from April/May to October, significant herbage production only began after the onset of the rains. Forage quality was estimated to be moderate at best, and often low. The presence of grass, forbs, and trees and shrubs during October were 38%, 56% and 6%, respectively, with 75% of the vegetation below 20 cm. Most grasses and forbs were recorded below 15 cm, with the forbs showing almost twice the presence below 5 cm as grasses. Shrubs were more evenly distributed throughout the profile to 125 cm. The flux in biomass and physiognomic structure is illustrated by the comparison ...

The scientists found two small peptides from widely cultivated crop species (one from broad beans and one from cowpea) that were especially effective.. Further work then confirmed that when these peptides were used together, and with a human peptide that is also an antimicrobial, their protective effects were beefed-up in a one-two antimicrobial punch.. Associate Professor and Head of Microbiology at Trinity College Dublin, Ursula Bond, led the team that has just published its research in the journal Applied and Environmental Microbiology.. She said: There are two major advantages to these small peptides in that no resistance mechanisms have emerged yet, and in that they can be inexpensively synthesised in the lab. Initially, our aim was to ...

  • Comparative analyses of WOX4 transcription and function are presented in Arabidopsis ( Arabidopsis thaliana ), a simple-leafed plant with collateral vasculature, and in tomato ( Solanum lycopersicum ), a dissected-leafed species with bicollateral venation. (
  • RNA interference-induced down-regulation of WOX4 in Arabidopsis generated small plants whose vascular bundles accumulated undifferentiated ground tissue and exhibited severe reductions in differentiated xylem and phloem. (
  • That first year at university was, academically, "a total disaster," she says, but she found her groove the following year, doing research on Arabidopsis thaliana in a plant pathology lab headed by Robin Cameron, now at McMaster University. (
  • Brady remained at U of T for graduate school, joining the lab of Peter McCourt and initially looking for Arabidopsis genes encoding proteins that interact with the plant hormone abscisic acid. (
  • In Benfey's lab, Brady's research involved analyzing the mRNAs present in individual cell types in Arabidopsis roots during different stages of development to reveal the patterns of gene expression that enabled their growth and maturation. (
  • To study the regulation of plant meristem activity and cell proliferation, we have examined the tissue-specific accumulation of cdc2 transcripts in Arabidopsis thaliana and the related crucifer radish (Raphanus sativus) by in situ hybridization using A. thaliana cdc2 cDNA sequences as a probe. (
  • Imprinted genes have been identified in maize and Arabidopsis thaliana , but crosses in a variety of species suggest that the effect of imprinting on seed development is widespread throughout the angiosperms. (
  • To see whether this gene is also essential for syncytium development, the role of ENOD40 was investigated in the non-legumes tomato and Arabidopsis upon cyst nematode infection. (
  • In addition to growth by cell division, a plant may grow through cell elongation. (

  • However, according to a new study in the open access journal PLOS ONE , very low doses of the pungent compound spur plant growth. (
  • According to Dooley´s advisor Peter Ward, a UW professor of biology, the rapid plant growth brought on by small concentrations of hydrogen sulfide could be the result of a genetic mechanism that allowed plants to survive these mass extinction events. (
  • Ward said larger plants would have had a better chance at survival, so it makes sense that small dose of the deadly compound would spur growth. (
  • Why is Soil Water Important to Plant Growth? (
  • Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance. (
  • When air temperatures are favorable for plant growth, soil water is the limiting factor for photosynthesis. (
  • Rapid growth does not occur in all plant parts simultaneously. (
  • Growth of plant parts is reduced or delayed when green leaf area is removed. (
  • We normally accept natural plant growth habits and design a growing system to accommodate their growth. (
  • If the plant growth habit was altered in such a manner so that the growing density increases without sacrificing productivity, greater efficiency can be achieved. (
  • Presently, new modifications are being made to double the growing density by dividing the existing growth chamber to two separate chambers so that two plants can be grown. (
  • But the growth guide and light distribution system had to be developed first to determine the (Pinch Roller) plant spacing. (
  • Monocot plants usually have higher efficiency in photosynthesis mainly due to its growth characteristics allowing better light penetration without shading other foliage. (
  • Takashima, Y., "Development of Plant Growth Guide and Light Distribution System," SAE Technical Paper 2003-01-2458, 2003, . (
  • During their early growth, the embryos of all vascular plants exist as virtual parasites depending for nutrition on either the gametophyte or the previous sporophyte generation through the agency of the gametophyte or, in the special case of the angiosperms, upon an initially triploid tissue, the endosperm, which is itself nourished by the parent sporophyte. (
  • Tobacco is preferred as the host plant because of its rapid growth and high volume of production. (
  • This is allowed to proliferate and the plant expresses the recombinant protein, being stimulated to grow rapidly using controlled plant growth stimulators. (
  • We have recently shown that beyond its role in respiration, this protein complex is also involved in defence signalling in plants by helping plants to respond to invading organisms like pathogenic fungi and it also alter the growth of roots. (
  • Scientists are getting to the root of plant growth in space. (
  • Auxin is a plant growth hormone that helps guide the direction of root growth. (
  • However, space-grown plants show differences in root-tip distribution of cytokinin, a plant hormone that often works in concert with auxin to regulate cell division and tissue growth. (
  • Spaceflight also causes changes in the expression of many genes that are regulated by auxin and other plant hormones, as well as genes that regulate the size and shapes of cells that influence root growth patterns. (
  • These findings suggest that it may be possible to eliminate certain unnecessary environmental responses by genetic modification to produce plant varieties better adapted for growth in microgravity (Paul, 2017). (
  • Plants experiencing space flight are quite normal in appearance but can exhibit growth habits distinctly different from plants on earth. (
  • Scientists at UC Riverside have identified the molecular mechanism by which photoreceptors called phytochromes control plant growth and development. (
  • Phytochromes control plant growth and development by changing the amount or stability of another group of proteins called transcription factors whose job is to turn genes on and off. (
  • Now that we understand how light is causing changes in growth and development, we can engineer plants to be blind to their neighbors, so we can plant them more densely without seeing a decrease in yield," Chen said. (
  • This book focuses on stress caused by the inanimate components of the environment associated with climatic, edaphic and physiographic factors that substantially limit plant growth and survival. (

  • The phytohormone cytokinin plays diverse roles in plant development, influencing many agriculturally important processes, including growth, nutrient responses and the response to biotic and abiotic stresses. (
  • 1955 ), and subsequent studies identified the cytokinin zeatin as an endogenous plant growth regulator ( Letham, 1973 ). (
  • Early hypotheses about auxin transport posited that the hormone was produced in young leaves and shoot tips and worked its way "down" the plant into stems and roots to promote plant development and growth. (
  • For example, specific recognition responses in plants trigger formation of the hypersensitive response and activation of host defense mechanisms, resulting in restriction of pathogen growth and disease development. (
  • Current knowledge of the spatiotemporal control of brassinosteroid function in plants, focusing on primary root development and growth, stem cell self-renewal and death, and adaptation to environmental stress, is summarized in this Review from Ana Caño-Delgado and team. (
  • The idea of the conference 'Physiology, Growth and Development of Plants and Cells in Culture' (Lancaster, 1992) was to introduce specialists in different areas of plant physiology to micropropagators, with the express aims of disseminating as wide a range of information to as large a number of participants as possible, and beginning new discussions on the constraints and potentials affecting the development of in vitro plant production methods.

  • In New York, Cornell researchers have shown multiple benefits to plant growth and nutrition when they investigated the effect of soy flour, a plant-derived biostimulant, on coated broccoli seed . (
  • Results showed enhanced plant growth and development through measurements of biomass, plant height, leaf area, leaf development, and chlorophyll content. (
  • Soy flour-coated seeds had greater seedling root and shoot growth compared with the noncoated control, and soy flour applied at 30%, 40%, and 50% in the coating formulation increased the total nitrogen per plant compared with the noncoated control. (

  • However, isotopic labeling with deuterium ((2)H) in higher plants at the level of 40% and higher is complicated by both physiological responses, particularly water exchange through transpiration, and inhibitory effects of D2O on germination, rooting, and growth. (
  • Growth in individual chambers under continuous air perfusion with dried sterile-filtered air enables long-term cultivation of multiple plants at different D2O concentrations. (
  • Economic development creates opportunities to grow state, local and metro areas, which are essential for economic growth, improved quality of life and community development. (
  • The scientists at the University of Delhi have shown that inserting a bacterial gene that makes a protein named Cry1Ac into genomes of plants appears to cause developmental defects, growth retardation and sterility in the plants. (
  • This simple and fully automated non-invasive screening methodology allows to simultaneously monitoring stress-induced changes in photosynthetic yield and plant growth. (
  • In this sense, for each selected line we could determine the specificity of the response that means, the type of stress to which the auxin-related line show improved or suboptimal effect on root or shoot growth and photosynthesis in comparison to wild type plants. (
  • Our results contribute to the understanding of stress-induced root growth and root development retardation effect. (
  • The real biological potential of the selected genes was tested through the selection of mutants or overexpressing lines and further functional assessments via a screening methodology in which root and shoot growth and changes in photosystem II photochemical efficiency (Fv/Fm), non-photochemical quenching (NPQ) and photochemical quenching are used to determine the plant stress response.

  • Umeå University, Faculty of Science and Technology, Department of Plant Physiology. (
  • Two experiments on the International Space Station found normal distribution of auxin in the roots of space-grown plants, suggesting weightlessness does not affect this system. (
  • At later stages of the gynoecium development, auxin biosynthesis at the apex may be critical to formation of the style and stigma. (
  • Their analysis of these genes suggests that the NGA proteins regulate gynoecial development via the control of auxin homeostasis. (
  • Cytokinins were discovered in a search for factors that promote cell proliferation in cultured plant cells in concert with a second phytohormone, auxin. (
  • Thus, specification of vascular fate in leaf primordia is dependent upon appropriate auxin transport, localization, and signaling, implicating auxin as a predominant patterning factor during early vascular development. (
  • A study in Developmental Cell shows the importance of the interplay between local production and transport of the key hormone auxin to plant development. (
  • The study sheds light on the importance of when and where the plant hormone auxin is produced and explores the interplay between auxin synthesis and transport that moves auxin throughout the plant. (
  • Specifically, the research shows that local auxin production is required to keep plants healthy. (
  • That is, roots will degenerate if auxin is not produced in the root, or flowers will be sterile if auxin is not made at the right place and the right time in the flower, despite the fact that the hormone can be transported throughout the plant. (
  • We knew how auxin was transported within the plant and how plants respond to auxin, but surprisingly we didn't know until recently how and where auxin is produced by the plant," said Javier Brumos, an NC State post-doctoral researcher and first author of a paper describing the research. (
  • That led to the question of how important local production of auxin in the root - that is, auxin that moves from root cell to root cell rather than being transported from the shoot - is to plant development," Brumos said. (
  • Using a variety of elegant experiments on Arabadopsis, or mustard weed, the NC State researchers showed the importance of local auxin production in plant roots. (
  • First, the researchers created hybrid plants by grafting healthy, auxin-producing shoots onto roots that didn't produce auxin to see whether auxin could be transported from shoot to root to keep roots healthy. (
  • It turns out that plants may choose to make auxin in the place where they want it to accumulate rather than always bring auxin from other parts of the plant," said Anna Stepanova, an assistant professor in the Department of Plant and Microbial Biology at NC State and corresponding author of the paper. (
  • If there is no local auxin in the root, the plant loses its root meristematic activity and the root degenerates. (
  • Again, plants with root-made auxin had viable roots, while plants reliant on auxin transport from shoots had faulty roots. (
  • The researchers also examined the role of local auxin in flowers and leaves and again saw that the sites of the biosynthesis of this hormone are critical, in this case, for full fertility and normal leaf development. (
  • The take-home message of this study is that local auxin production and transport work together to keep plants healthy. (
  • In lower plants like mosses, auxin and cytokinin regulate the creation and the stability of the differentiated state of various cell types. (
  • In fact, most of the major plant hormones, such as auxin, cytokinins, abscisic acid, and strigolactones, control both lateral root formation and nodule organogenesis, but often in an opposite manner. (
  • Through this method, we deciphered some components of the ROS-auxin regulatory network involved in plant stress adaptation. (
  • By using cell biology tools, the effect of ROS accumulation upon oxidative stress on the underlying mechanisms controlling auxin-dependent root apical meristem activity and lateral root development and on the subcellular trafficking mechanisms controlling PIN polarity and degradation was inferred. (
  • Altered auxin homeostasis in pin6-2 and 35S:PIN6 plants is associated to altered rosette shape, and results in significantly improved water retention under salt stress treatments. (
  • A local accumulation of auxin is crucial for syncytium development.Analysis of cellulase expression patterns in tomato revealed that two auxin-inducible members (LECel7 and LE-Cel8) were speci¿ cally up-regulated during the onset of syncytium development. (
