Project description:Lettuce is one of most consumed vegetables globally. This crop is susceptible to abiotic stresses. To understand the molecular mechanisms of stress response in lettuce, global transcriptome analysis was conducted. This analysis revealed distinctive temporal expression patterns among the stress-regulated genes in lettuce plants exposed to abiotic stresses

Project description:Potato plants are sensitive to multiple abiotic stresses such as drought, low temperature and high light. We analyzed the transcriptome of WT potato plants as well as that of transgenic potato plants expressing the Arabidopsis stress related transcription factor CBF1 that confers tolerance to multiple stresses.

Project description:Potato plants are sensitive to multiple abiotic stresses such as drought, low temperature and high light. We analyzed the transcriptome of WT potato plants as well as that of transgenic potato plants expressing the Arabidopsis stress related transcription factor CBF1 that confers tolerance to multiple stresses. Wild type and AtCBF1OX transgenic potato plants were exposed to low temperature, high light, drought or kept under control conditions as described below in detail, and transcriptional changes induced by the different stresses were analyzed.

Project description:Biotic and abiotic stresses limit agricultural yields, and plants are often simultaneously exposed to multiple stresses. Combinations of stresses such as heat and drought or cold and high light intensity, have profound effects on crop performance and yeilds To analyze such responses, we initially compared transcriptome changes in ten Arabidopsis thaliana ecotypes using cold, heat, high light, salt and flagellin treatments as single stress factors or their double combinations.

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: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

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.
