Project description:MicroRNAs (miRNAs) play an important role as regulators of gene expression. In plants they affect a wide variety of biological process like growth, development and response to biotic and abiotic stress. Glycine max is one of the most important crop worldwide due to its rich protein and oil content. Drought and salt stress are the main abiotic stresses that affect soybean. Salt stress impacts the fisiology of the plants due to the damage in the photosynthetic rate, growth and development. This work aim to identify salt-stress responsive miRNAs and their respective targets in Glycine max using high-throughput RNA sequencing technology.

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: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. Arabidopsis thaliana plants of ecotypes (Col, Ler, C24, Cvi, Kas1, An1, Sha, Kyo2, Eri and Kond) were subjected to the following stress treatments: Salt, Cold, Heat, High Light (HL), Salt+Heat, Salt+HL, Cold+HL, Heat+HL, as well as FLG (Flagellin, flg22 peptide), Cold+FLG, Heat+FLG

Project description:Environmental stresses influence the growth of plants and the productivity of crops. Salinity is one of the most important abiotic stresses for agricultural crops. PCD is induced by various biotic and abiotic stresses in algae and higher plants, including high salinity treatment. OsPDCD5, an ortholog to mammalian-programmed cell death 5, is up-regulated under low temperature and NaCl treatments. We found that the transgenic rice which constitutively expressed anti-OsPDCD5 increased salt stress tolerance in unique ways. By using the Rice Genome Microarray, we identified target genes that were regulated in transgenic rice plants by anti-OsPDCD5.

Project description:Studies investigating crop resistance to biotic and abiotic stress have largely focused on plant responses to singular forms of stress and individual biochemical pathways that only partially represent stress responses. Thus, combined biotic and abiotic stress treatments and the global assessment of their elicited metabolic expression remains largely unexplored. In this study, we employed targeted and untargeted metabolomics to investigate the metabolic responses of maize (Zea mays) to both individual and combinatorial stress treatments using heat (abiotic) and Cochliobolus heterostrophus infection (biotic) experiments. Ultra-high-performance liquid chromatography-high-resolution mass spectrometry revealed significant metabolic responses to C. heterostrophus infection and heat stress, and comparative analyses between these individual forms of stress demonstrated differential elicitation between the two global metabolomes. In combinatorial experiments, treatment with heat stress prior to fungal inoculation negatively impacted maize disease resistance against C. heterostrophus, and distinct metabolome separation between combinatorial stressed plants and the non-heat stressed infected controls was observed. Targeted analysis revealed inducible primary and secondary metabolite responses to biotic/abiotic stress, and combinatorial experiments indicated that deficiency in the hydroxycinnamic acid, p-coumaric acid, may lead to the heat-induced susceptibility of maize to C. heterostrophus. Collectively, these findings demonstrate that abiotic stress can predispose crops to more severe disease symptoms, underlining the increasing need to investigate defense chemistry in plants under combinatorial stress.

Project description:Mannitol is a sugar alcohol that serves as a compatible solute contributing to exceptional salt tolerance in several plant species. Arabidopsis plants transformed with the mannose-6-phosphate reductase (M6PR) gene from celery were dramatically more salt tolerant. Following treatment with 100mM NaCl, transgenic plants, relative to wild type (WT), were more successful in bolting, flowering, and production of viable seed, were less chlorotic/necrotic, and with less inhibition of growth (leaf number, rosette diameter, plant height, stalk number, and dry weight). When irrigated with 200 mM NaCl, both transformants and WT plants died without producing seeds, but M6PR transformants bolted and showed significantly less chlorosis and necrosis and had higher survival rates and dry weights than those of WT. Under normal growth conditions there were no negative effects of the M6PR transgene on overall growth (leaf number, rosette diameter, plant height, stalk number, and dry weight), or time to bolting/flowering or seed production compared to wild type (WT). Despite the lack of effects on phenotype in the absence of salt stress, genome wide expression analyses indicated that expression levels of more than 2000 genes were altered by presence of the M6PR transgene: however, there were many fewer differences observed between the M6PR and non-transgenic plants in the presence of salt stress (459), suggesting that M6PR pre-conditioned the plants for exposure to salinity. Gene categories most affected in the M6PR transgenic plants were involved in DNA binding, signal transduction, metabolism/energy, cell structure, membrane transport, defense response, and transcription. Notably, a large number of known stress genes were induced, including those related to cell walls, biotic stress, and ABA- and ethylene-responses. Our work and that in other labs has suggested that mannitol acts as an osmoprotectant, but mannitol levels are invariably quite low, and perhaps inadequate to explain its effects as an osmoprotectant. The gene expression data here indicate that stress tolerance of mannitol-producing Arabidopsis is also due, at least in part, to enhanced expression of a number of stress inducible genes related to both biotic and abiotic stress tolerance. Both M6PR transgenic and Col WT plants were grown in the growth chamber in the absence and presence of salt stress. Plants from 20 days after sowing (6 days after salt treatment) were used for RNA extraction and hybridization on Affymetrix microarrays. There were two biological replicates for each genotype and salt treatment combination.
