Abstract:
Mitogen-Activated Protein Kinases (MAPKs) cascade plays an important role in regulating plant growth and development, generating cellular responses to the extracellular stimuli. MAPKs cascade mainly consist of three sub-families i.e. mitogen-activated protein kinase kinase kinase (MAPKKK), mitogen-activated protein kinase kinase (MAPKK) and mitogen activated protein kinase (MAPK), several cascades of which are activated by various abiotic and biotic stresses. In this work we have modeled the holistic molecular mechanisms essential to MAPKs activation in response to several abiotic and biotic stresses through a system biology approach and performed its simulation studies. As extent of abiotic and biotic stresses goes on increasing, the process of cell division, cell growth and cell differentiation slow down in time dependent manner. The models developed depict the combinatorial and multicomponent signaling triggered in response to several abiotic and biotic factors. These models can be used to predict behavior of cells in event of various stresses depending on their time and exposure through activation of complex signaling cascades.

Project description:The effect of the abiotic stresses, heat, cold and salt on gene expression in Arabidopsis thaliana
2006-03-21 | E-TIGR-2 | biostudies-arrayexpress
Project description:Following pathogen infection, plants have developed diverse mechanisms of defense that enhance their immune system for more robust induction of defense responses against recurrent environmental stresses. This induced resistance can be heritable to the progeny, rendering them more tolerant to stressful events. Although within-generational induction of tolerance to abiotic stress is a well-documented phenomenon in virus-infected plants, the transgenerational inheritance of tolerance to abiotic stresses in their progenies has not been explored. Here, we show that infection of Nicotiana benthamiana plants by Potato virus X (PVX) and by a chimeric Plum pox virus (PPV) expressing the P25 protein of PVX (PPV-P25), but not by PPV, conferred tolerance to both salt and osmotic stresses to the progeny, which correlated with the level of virulence of the pathogen. This transgenerational tolerance to abiotic stresses in the progeny was partially sustained even if the plants experience a virus-free generation. Moreover, progenies from a Dicer-like3 mutant, irrespective whether their parents were infected or not, mimicked the enhanced tolerance to abiotic stress observed in progenies of PVX-infected wild-type plants, suggesting the involvement of 24-nt small interfering RNAs in the transgenerational tolerance to abiotic stress induced by virus infection. RNAseq analysis supported the upregulation of genes related to protein folding and response to stress in the progeny of PVX-infected plants. From an environmental point of view, the significance of virus-induced transgenerational tolerance to abiotic stress could be questionable, as its induction was offset by major reproductive costs arising from a detrimental effect on seed production

Project description:Environmental stresses such as drought, heat and salinity limit plant development and agricultural productivity. While individual stresses have been studied extensively, much less is known about the molecular interaction of responses to multiple stresses. To address this problem, we investigated molecular responses of Arabidopsis thaliana to single, double, and triple combinations of salt, osmotic, and heat stresses. A metabolite profiling analysis indicated the production of specific compatible solutes depending on the nature of the stress applied. We found that in combination with other stresses, heat has a dominant effect on global gene expression and metabolites level patterns. Treatments that include heat stress lead to strongly reduced transcription of genes coding for abundant photosynthetic proteins and proteins regulating the cell life cycle, while genes involved in protein degradation are upregulated. Under combined stress conditions, the plants shifted their metabolism to a survival state characterized by low productivity. Our work provides molecular evidence for the dangers for plant productivity and future world food security posed by heat waves resulting from global warming. We highlight candidate genes, many of which are functionally uncharacterized, for engineering plant abiotic stress tolerance.

Project description:We report the role of LSM2-8 complex in the Arabidopsis tolerance to abiotic stresses. LSM2-8 controls gene expression reprogramming at the post-transcriptional level by promoting the splicing of pre-mRNA. This function is selectively achieved over selected transcripts depending on stress nature.

Project description:Here, we investigated the function of the plant-specific SR protein RS33 in pre-mRNA splicing regulation and abiotic stress responses in rice. The loss-of-function mutant, rs33, showed increased sensitivity to salt and low-temperature stress. Genome-wide analyses of gene expression and splicing in seedlings subjected to these stresses identified multiple splice isoforms from stress-responsive genes dependent on RS33. The number of RS33-regulated genes is much higher under low-temperature stress as compared to salt stress. Our results suggest that this plant-specific splicing factor plays crucial and distinct roles during plant adaptation to abiotic stresses.

Project description:Chromatin modifications play important roles in plant adaptation to abiotic stresses, but the precise function of histone H3 lysine 36 (H3K36) methylation in drought tolerance remains poorly evaluated. Here, we report that SDG708, a specific H3K36 methyltransferase, functions as a positive regulator of drought tolerance in rice.

Project description:Sunflower is an important source of vegetable oil worlwide. A differential organ-specific sunflower ESTs was previously generated by a subtractive hybridization method, including a considerable number of abiotic stress associated sequences. The objective of this work is to analyze the sunflower gene expression of previously identified candidate genes under a comprehensive microarray analysis of the leaf transcriptoma under cold and salinity stresses, considering the impacts of these abiotic stresses on sunflower yield in many productive areas. The aimed of this work is to perform genome analysis of sunflower based on its functional regions and the characterization of the sunflower transcriptoma profiles for different organ-specific genes. Abiotic-related expressed genes were the target of this characterization through a gene expression analysis of the local EST bank (annotated according to Gene Ontology Annotation) using a cDNA organ-specific microarray chip approach. We analyzed 287 differentially expressed genes derived from leaf, stem, R1 and R4 flower developmental stages. Transcriptional analysis allowed the detection of three different groups of genes according to their expression patterns. Group 1 contained 112 up-regulated genes under abiotic stress conditions (cold or salinity), whereas Group 2 (126 genes) did not show changes in their expression levels. On the other hand, 49 genes were classified as Group 3 included were down-regulated genes under both stresses. Eighty genes exhibited a significative fold change under abiotic stress conditions, being six of them validated by qRT-PCR. Microrarray profiling of cold and NaCl-treated sunflower leaves revealed dynamic changes in transcript abundance, including transcription factors, defense/stress related proteins, and effectors of homeostasis, all of which highlight the complexity of both stress responses. This finding provides identification of many transcriptional processes occurring under abiotic stress in sunflower for genes isolated from organ-specific cDNA libraries Keywords: gene expression profile of organ-specific sunflower transcriptoma in response to NaCl and cold
