TT2 controls rice thermotolerance through SCT1-dependent alteration of wax biosynthesis (Nature Plants)

January 21, 2022 in /by

Global warming severely affects agricultural harvests, risking food security. To deal with heat stress, plants show different strategies. Indeed, heat increases intracellular Ca2+ levels to activate a heat shock response. In addition, GTP-binding proteins, which transduce extracellular signals to intracellular effectors, regulate Ca2+ currents when plants face abiotic stresses through calmodulin-binding proteins (CaM). In this […]

Phosphatidic acid modulates MPK3- and MPK6- mediated hypoxia signaling in Arabidopsis (Plant Cell)

January 7, 2022 in /by

Plants experience changes in gene expression and cellular metabolism to improve their survival to abiotic stresses, such as hypoxia. It has been observed that environmental signals induce phospholipase D (PLD) which generates phosphatidic acid (PA) by cleaving membrane phospholipids. Indeed, submergence induces the accumulation of PA, however, the mechanisms underlying this response have been unknown. […]

Prediction of conserved variable heat and cold stress response in maize using cis-regulatory information (Plant Cell)

December 10, 2021 in /by

Several transcription factors (TFs) have been identified previously as responsive to cold and heat stresses in maize. Variation in TF binding sites (TFBS) determine changes in the expression of target genes in response to the aforementioned stresses. Traditionally, single varieties were used to study TFBS variation rather than different species which are, putatively, a source […]
