Project description:Understanding the molecular differences in plant genotypes contrasting for heat sensitivity can provide useful insights into the mechanisms that confer heat tolerance in plants. This study is focused on comparative physiological and proteomic analyses of heat sensitive (ICC16374) and tolerant (JG14) genotypes of chickpea (Cicer arietinum L.) when subjected to heat stress at anthesis.Comparative gel-free proteome profiles indicated differences in the expression levels and regulation of common proteins that are associated with heat tolerance in contrasting genotypes under heat stress. The differentially regulated proteins were grouped into three categories based on their involvement in the molecular functions, cellular location and biological processes. Besides the identification of heat shock proteins, other proteins such as acetyl-CoA carboxylase, pyrroline-5-carboxylate synthase (P5CS), ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCo), phenylalanine ammonia-lyase (PAL) 2, ATP synthase, glycosyltransferase, sucrose synthase and late embryogenesis abundant (LEA) proteins were strongly associated with heat tolerance in chickpea. Several crucial proteins such as cystathionine gamma-synthase, glucose-1-phosphate adenyltransferas, malate dehydrogenase, threonine synthase, and non-cyanogenic ß-glucosidase were induced by heat only in the heat tolerant genotype. Based on pathway analysis, we propose that proteins which are essentially related to the electron transport chain in photosynthesis, aminoacid biosynthesis, ribosome synthesis and secondary metabolite synthesis may play key roles in inducing tolerance to heat stress.

Project description:BACKGROUND: Climate change will lead in the future to an occurrence of heat waves with a higher frequency and duration than observed today, which has the potential to cause severe damage to seedlings of temperate maize genotypes. In this study, we aimed to (I) assess phenotypic variation for heat tolerance of temperate European Flint and Dent maize inbred lines, (II) investigate the transcriptomic response of temperate maize to linearly increasing heat levels and, (III) identify genes associated with heat tolerance in a set of genotypes with contrasting heat tolerance behaviour. RESULTS: Strong phenotypic differences with respect to heat tolerance were observed between the examined maize inbred lines on a multi-trait level. We identified 607 heat responsive genes as well as 39 heat tolerance genes. CONCLUSION: Our findings indicate that individual inbred lines developed different genetic mechanisms in response to heat stress. We applied a novel statistical approach enabling the integration of multiple genotypes and stress levels in the analysis of abiotic stress expression studies.

Project description:A comparative study ware made to know the abiotic stress tolerance machanism between tolerant and susceptible plants at flowering stage. The tolerance in response to abiotic stresses are sum of expression of thousands of genes at a particular stage. Tomato plants were exposed to drought and heat stress for RNA extraction and hybridization on Affymetrix microarrays. To study the molecular mechanism of abiotic stress tolerance to increase the tolerance in tomato plants, transcripts of tolerant and susceptible plants at flowering stage were compared in response to heat and water stress.

Project description:This study was aimed to deal with a comparative proteome analysis of the two chickpea genotypes with contrasting response to drought stress, ICC 4958 (drought-tolerant, DT) and ICC 1882 (drought-sensitive, DS). Proteins were extracted from the root tissues collected from the control and drought stressed plants of both the genotypes. NanoLC-MS/MS analysis of the protein sample was performed using EASY-nLC 1000 system for the separation and identification of peptides/proteins. This study provided a mechanistic insight of drought stress tolerance in chickpea.

Project description:Drought avoidance mechanism is one of the component mechanisms contributing for drought tolerance in which roots serves as the master keys, but poorly understood. Comparative analysis of drought stress responsive root transcriptome between drought-tolerant Nootripathu and drought-susceptible IR20 In this study, we used microarrays to dissect out drought responsive changes in roots of two contrasting rice genotypes viz., IR 20 (a shallow rooted lowland indica genotype) and Nootripathu (a deep rooted upland indica genotype) at molecular level.
