Project description:au08-06_mpk6_heat_stressed - au08-06_mpk6_heat_stressed - Mitogen Activated Protein Kinase (MAPK) signaling pathways are key regulators of cell proliferation, differentiation and stress effectors. The core of the MAP kinase signal transduction cascade is composed of a three-kinase module consisting of a MAP kinase kinase kinase (MAPKKK), a MAP kinase kinase (MAPKK), and a MAP kinase (MAPK). The signaling pathway is activated upon stimulation by a phosphorylation cascade. In previous studies, it was shown that the mpk6 KO mutant plants are significantly more tolerant to heat stress in comparison to wt and that after 3h treatment at 37°C, an activation of heat-shock proteins occures in the mpk6 mutant. To better understand the changes occuring in the mpk6 mutant upon heat stress at the gene expression level, we would like to perform a microarray transcriptomic analysis. - Mitogen Activated Protein Kinase (MAPK) signaling pathways are key regulators of cell proliferation, differentiation and stress effectors.

Project description:HSFA1s are a gene family of HSFA1 with four members, HSFA1a, HSFA1b, HSFA1d, and HSFA1e. HSFA1s are the master regulators of heat shock response. As a part of the heat shock response, HSFA2 can prolong the heat shock response and amplify the heat shock response in response to repeat heat shock. To identify the heat-shock-responsive genes differentially regulated by HSFA1s and HSFA2, we compared the transcriptomic differences of plants containing only constitutively expressed HSFA1s or HSFA2 after heat stress. hsfa2 (the KO mutant of HSFA2, Col-0 background) and A2QK-10 (CaMV 35S:HSFA2 in QK mutant; QK is HSFA1a/b/d/e quadruple KO mutant) were used to compare the difference of heat shock response when plants lack HSFA1s or HSFA2. The aim is to find the HSFA1s- and HSFA2-preferred regulating genes after heat stress. As the control samples, wild type is the plant with normal heat shock response, and QK (HSFA1s KO mutant, Col-0 and Ws mixed background) is the plant that lost the heat shock response controlled by HSFA1s.

Project description:Translation initiation factors of the eIF4E family play a crucial role in regulating translation and the cellular metabolism of mRNAs. In this study, we show that loss of the class II eIF4E known as 4EHP (nCBP) confers enhanced basal and acquired thermotolerance and causes a mild flowering delay without major root defects. Under heat stress, 4EHP-GFP re-localizes from a diffuse cytosolic pattern to cytoplasmatic foci, where it co-localizes with canonical stress granule (SG) markers. Transcriptomic analysis under control, acclimation and heat stress conditions reveals that 4EHP limits the accumulation of a specific subset of heat-responsive mRNAs, especially those encoding several heat shock proteins (HSPs), which remain constitutively expressed in 4ehp-1 mutant under control conditions and during heat stress. Our results indicate that 4EHP regulates chaperone production, via heat-responsive SG regulatory pathway for the corresponding mRNAs.
