Mar author 2016 In many plant species, an exposure to a sublethal temperature triggers an adaptative response called acclimation. This response involves an extensive molecular reprogramming that allows the plant to further survive to an otherwise lethal increase of temperature. A related response is also launched under an abrupt and lethal heat stress that, in this case, is unable to successfully promote thermotolerance and therefore ends up in plant death. Although these molecular programmes are expected to have common players, the overlapping degree and the specific regulators of each process are currently unknown. We have carried out a high-throughput comparative proteomics analysis during acclimation and during the early stages of the plant response to a severe heat stress that lead Arabidopsis seedlings either to survival or death. This analysis dissects these responses, unravels the common players and identifies the specific proteins associated with these different fates. Thermotolerance assays of mutants in genes with an uncharacterized role in heat stress demonstrate the relevance of this study to uncover both positive and negative heat regulators and pinpoint a pivotal role of JR1 and BAG6 in heat tolerance. 10.1111/pce.12664 1365-3040 0140-7791 Plant Cell and Environment Plant Cell Environ. 2016; 39(6):1264-78 26580143 http://hdl.handle.net/20.500.12105/5224 Acclimation Heat stress response iTRAQ Proteomics Plants HIGH-TEMPERATURE STRESS GENOME-WIDE ANALYSES RIBOSOMAL-PROTEINS QUANTITATIVE PROTEOMICS ELEVATED-TEMPERATURE MOLECULAR CHAPERONES GENETIC-EVIDENCE THALIANA THERMOTOLERANCE TOLERANCE Dissecting the proteome dynamics of the early heat stress response leading to plant survival or death in Arabidopsis
