Role of CAMTA1 gene under drought stress

ABSTRACT: The CAMTA1 mutant and Col-0 were studied under water and drought condition. The camta1 showed stunted primary root growth under osmotic stress. The expression analysis revealed drought recovery as major indicative pathway along with membrane and chloroplast related protein in camta1 under drought stress. Large number of positively regulated genes were related to osmotic balance, transporters, AP2 and ABA. We used Affymetrix expression analysis to validate the role of CAMTA1 under drought stress. The RNA of Col-0 and camta1 mutant were isolated in water and drought condition.The ATH1 gene chip was used for expression analysis.

Genome-wide analysis of stress-responsive genes and alternative splice variants in Arabidopsis roots under osmotic stresses

Project description:The shoots and roots of a plant respond differently to osmotic stress, as they have distinct functions and anatomical structures. Under conditions of high solute concentration, such as in saline soils or drought, water uptake by the roots is reduced, resulting in cellular dehydration. In this study, we performed transcriptional profiling of roots of Arabidopsis under osmotic stress conditions such as high salinity and drought using mRNA-Seq for the assessment of gene expression changes in roots of Arabidopsis. mRNA-Seq analysis showed that many differentially expressed genes showed differential expressions under both salt stress and drought stress conditions in roots and were distinct from aerial parts. We confirmed 68 transcription factor genes which is involved in osmotic stress signal transduction in roots and are connected tightly. Interestingly, well-known ABA-dependent and/or -independent osmotic stress-responsive genes were less increased in roots, indicating that osmotic stress response in roots might be regulated by stress pathways other than well-known pathways. We identified 26 osmotic stress-responsive genes, which have alternative splicing variant isoforms, showed distinct expression in roots under osmotic stress conditions from the mRNA-Seq analysis. Quantitative RT-PCR confirmed that alternative splicing variants, such as ANNAT4, MAGL6, TRM19, and CAD9, have differential expressions in roots under osmotic stress conditions, indicating that alternative splicing is an important regulatory mechanism in osmotic stress response in roots. Taken together, our study suggest that many transcription factor families are involved in osmotic stress response in roots and tightly connected each other. In addition, alternative splicing and function of alternative splicing variant isoforms are also important in osmotic stress response in roots. To understand the alternative splicing mechanism in roots, further study is necessary.

ß-amylase1 mutant Arabidopsis plants show improved drought tolerance due to reduced starch breakdown in guard cells

Project description:In plants, drought stress is a major growth limiting factor causing cell water loss through open stomata. In this study, guard cell-specific transcripts from drought-stressed Arabidopsis plants were analyzed and a down-regulation of β-amylase 1 (BAM1) was found. In previous studies, BAM1 was shown to be involved in stomatal starch degradation under ambient conditions. Impaired starch breakdown of bam1 mutant plants was accompanied by decreased stomatal opening. Here, we show that drought tolerance of bam1 mutant plants is improved as compared to wild type controls. Microarray-analysis of stomata-specific transcripts from bam1 mutant plants revealed a significant down-regulation of genes encoding aquaporins, auxin- and ethylene-responsive factors and cell-wall modifying enzymes. This expression pattern suggests that reduced water-uptake and limited cell wall extension are associated with the closed state of stomata of bam1 mutant plants. Together these data suggest that regulation of stomata-specific starch turnover is important for adapting stomata opening to environmental needs and its breeding manipulation may result in drought tolerant crop plants. Stress induced gene expression in Arabidopsis leaves and Stomata was measured after exposure to single drought stress. Drought stress conditions were analysed for both, Col-0 plants and a T-DNA insertion line for β-amylase 1. Six week old plants were treated with drought stress (5 days) according to Prasch and Sonnewald, 2013. Two to three biological replicates have been hybridized for each treatment.

Early drought-responsive changes in pepper leaves and roots

Project description:Drought is one of the major factor that limits crop production and reduces yield. To understand the early response of plants under nearly natural conditions, pepper plants were grown in a greenhouse and drought stressed by withholding water for one week. Plants adapted to the decreasing water content of the substrate by adjustment of their osmotic potential in roots by accumulation of raffinose, glucose, galactinol and proline. In contrast in leaves levels of fructose, sucrose and also galactinol increased. Due to the water deficit cadaverine, putrescine, spermidine and spermine accumulated in leaves whereas the concentration of polyamines was reduced in roots. These polyamines are suggested to rather act as stress protectants than for osmotic adjustment. To understand the molecular basis of the response to this early drought stress better, four suppression subtractive hybridisation libraries from leaves and roots were constructed. Microarray technique was used to identify differentially expressed genes. A total of 109 unique ESTs were detected. The diversity of the putative functions of all identified genes confirms the complexity of the plant response to drought stress. Keywords: Transcription profiling

Overexpression of the plastidial pseudo-protease AtFtsHi3 enhances drought tolerance while sustaining plant growth

Project description:With climate change, droughts are expected to be more frequent and severe, severely impacting plant biomass and quality. Here, we show that overexpressing the Arabidopsis gene AtFtsHi3 (FtsHi3OE) enhances drought-tolerant phenotypes without compromising plant growth. AtFtsHi3 encodes a chloroplast envelope pseudo-protease; knock-down mutants (ftshi3-1) are found to be drought tolerant but exhibit stunted growth. Altered AtFtsHi3 expression therefore leads to drought tolerance, while only diminished expression of this gene leads to growth retardation. To understand the underlying mechanisms of the enhanced drought tolerance, we compared the proteomes of ftshi3-1 and pFtsHi3-FtsHi3OE (pFtsHi3-OE) to wild-type plants under well-watered and drought conditions. Drought-related processes like osmotic stress, water transport, and abscisic acid response were enriched in pFtsHi3-OE and ftshi3-1 mutants following their enhanced drought response compared to wild-type. The knock-down mutant ftshi3-1 showed an increased abundance of HSP90, HSP93, and TIC110 proteins, hinting at a potential downstream role of AtFtsHi3 in chloroplast pre-protein import. Mathematical modeling was performed to understand how variation in the transcript abundance of AtFtsHi3 can, on the one hand, lead to drought tolerance in both overexpression and knock-down lines, yet, on the other hand, affect plant growth so differently. The results led us to hypothesize that AtFtsHi3 may form complexes with at least two other protease subunits, either as homo- or heteromeric structures. Enriched amounts of AtFtsH7/9, AtFtsH11, AtFtsH12, and AtFtsHi4 in ftshi3-1 suggest a possible compensation mechanism for these proteases in the hexamer.

Responses of Arabidopsis leaves to prolonged osmotic stress are mediated by their developmental stage

Project description:Drought is an important environmental factor affecting plant growth and biomass production. Despite this importance, little is known on the molecular mechanisms regulating plant growth under water limiting conditions. The main goal of this work was to investigate, using a combination of growth and molecular profiling techniques, how Arabidopsis thaliana leaves adapt their growth to prolonged mild osmotic stress. Fully proliferating, expanding and mature leaves were harvested from plants grown on plates without (control) or with 25mM mannitol (osmotic stress) and compared to seedlings at stage 1.03. Total RNAs were extracted using Trizol method from vegetative part of seedlings at stage 1.03 and leaves that are fully proliferating, expanding or mature. All plants were grown in vitro on medium without (0mM) or with mannitol (25mM) in three independent biological experiments. Each sample was pooled from multiple plants and multiple plates in one experiment. RNA samples were submitted to ATH1 array hybridization.
