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:Jasmonate and ethylene are two important plant hormones contributing plant resistance to biotic stresses synergistically. Our experimental results showed that two ethylene activated transcription factors (EIN3/EIL1) integrated both jasmonate and ethylene signaling in multiple developmental and defense events. To understand the importance of EIN3/EIL1 in jasmonate signaling, we utilized microarray analysis to identify how much the jasmonate regulated genes are governed by EIN3/EIL1. Our results indicated that EIN3/EIL1 act sequentially in a cascade of transcriptional regulation initiated by jasmonate.

Project description:Jasmonate (JA) is a plant hormone that controls trade-offs between plant growth and responses to biotic and abiotic stresses. Although recent studies uncover core mechanism for JA-induced responses in Arabidopsis thaliana, it remains elusive how plants attenuate those responses. We report here that a basic-helix-loop-helix type transcription factor named JA-INDUCIBLE MYC2-LIKE1 (JAM1) acts as a transcriptional repressor and negatively regulates JA signaling. Arabidopsis plants expressing the chimeric repressor for JAM1 exhibited a substantial reduction of JA responses, including JA-induced inhibition of root growth, accumulation of anthocyanin, and male fertility. These plants were also compromised in resistance to attack by Spodoptera exigua. Conversely, jam1-4 loss-of-function mutants showed enhanced JA responsiveness, including increased resistance to the insect attack. Competitive binding of JAM1 and MYC2 to the target sequence of MYC2 suggested negative regulation of JA signaling by JAM1 and suppression of MYC2 function. These results indicate that JAM1 plays a pivotal role in fine-tuning of JA-mediated stress responses and plant growth by negatively regulating JA signaling. Transcriptomes of ProJAM1:JAM1-SRDX, ProMYC2:MYC2-SRDX and wild-type Arabidopsis seedlings with or without jasmonic acid were compared.

Project description:Plants are essential for life on Earth converting light into chemical energy in the form of sugars. To adjust for changes in light intensity and quality, and to become as efficient as possible in harnessing light, plants evolved multiple light receptors, signaling, and acclimation mechanisms. In addition to altering plant metabolism, development and growth, light cues sensed by some photoreceptors, such as phytochromes, are also impacting many plant responses to biotic and abiotic stresses. Central for plant responses to different stresses are reactive oxygen species (ROS) that function as key signaling molecules. Recent studies demonstrated that respiratory burst oxidase homolog (RBOH) proteins that reside at the plasma membrane and produce ROS at the apoplast play a key role in plant responses to different biotic and abiotic stresses. Here we reveal that phytochrome B (phyB) and RBOHs function as part of a key regulatory module that controls ROS production, transcript expression, and plant acclimation to excess light stress. We further show that phyB can regulate ROS production during stress even if it is restricted to the cytosol, and that phyB, RBOHD and RBOHF co-regulate thousands of transcripts in response to light stress. Surprisingly, we found that phyB is also required for ROS accumulation in response to heat, wounding, cold, and bacterial infection. Taken together, our findings reveal that phyB plays a canonical role in plant responses to biotic and abiotic stresses, regulating ROS production, and that phyB and RBOHs function in the same regulatory pathway.

Project description:We report about the effects of temperature increase on rice response to Xanthomonas oryzae pv. oryzae using high throughput sequencing (RNA-Seq). The time course transcriptomic analysis revealed that temperature enhanced IRBB67 resistance to combined heat and Xoo. Our findings highlight altered cellular compartment by Xoo and heat stress in both susceptible (IR24) and the resistant (IRBB67). Interestingly, up-regulation of trehalose-6-phosphatase gene and low affinity cation transporter in IRBB67 suggest that IRBB67 maintained a certain homeostasis under high temperature to have its resistance enhanced. The interplay of both heat stress and Xoo responses as determined by up-regulated and down-regulated genes demonstrates how resistant plant cope with combined biotic and abiotic stresses. This study provides an understanding of how IRBB67 mediated resistance to Xoo under temperature get insight to cross talk in abiotic and biotic stress regulatory pathway.
