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:Plants in nature are exposed to combinations of abiotic and biotic stresses. Climate change driven increase in frequency of abiotic stress combinations is being detrimental to the plant survival and growth. Previously we found that Arabidopsis plants when exposed to combination of abiotic stresses termed as multifactorial stress combination (MFSC), the accumulation of multiple mild abiotic stresses becomes damaging to plants causing severe reduction in plant survival which otherwise not detrimental when exposed as single stresses. Here in this study, we investigated the role of a transcription factors Basic helix loop helix (bHLH35) in MFSC tolerance in Arabidopsis seedlings.
Project description:The plant hormone jasmonic acid (JA) has been known as a signal molecule that is induced by various stresses and mediates plant defense responses. Rice O. sativa inductively produces variety of defensive compounds upon abiotic and biotic stress conditions, such as wounding and insect attack. We identified wound-inducible genes by comparison with transcriptomes between wounded and untreated wild-type rice leaves.
Project description:We describe the transcriptional profiles upon 1 mM linolenic acid (Ln) treatment in Arabidopsis cell suspension cultures. Ln is an important fatty acid in plant. We found that Ln treatment induced the expression of 533 genes and repressed the expression of 2501 gene. GO analysis indicated that most of those genes related to Reactive Oxygen Species signaling, abiotic and biotic stress responses, and/or Jasmonic Acid biosynthesis and signaling. This study provides basic information on how Ln regulates the gene expression and fulfils its role in abiotic and biotic stresses.
Project description:HvPap-1 is a C1A cysteine protease from barley that has been associated to endogenous processes and responds to abiotic and biotic stresses. Overexpressing and silencing lines were constructed to test the response of plants with variations in the levels of HvPap-1 to different stresses. RNA-seq analyses were done to know how changes in HvPap-1 expression levels affect the expression of other genes and the effect of these changes in the response of the plant.
Project description:Iodine treatments specifically regulated the expression of several genes in shoot and root tissues, mostly involved in the plant defence response, suggesting the protective role of iodine against both biotic and abiotic stresses.
Project description:After treatment with peptids, SA, JA and Et plants are primed due to the induction of plant immune system allowing to fight against plant pathogens. We used microarray analysis to study the expression pattern of the diferents genes involved in plant defense mechanisms related to biotic and abiotic stresses
