Plants are often exposed not only to short-term (S) heat stress but also long-term (L) over several consecutive days. A few Arabidopsis mutants defective in L-heat tolerance have been identified, the molecular mechanisms involved less well understood than those S-heat tolerance. To elucidate mechanisms, we isolated new sensitive heat5 (sloh5) mutant from EMS-mutagenized seeds of L-heat-tolerant Col-0. The sloh5 was hypersensitive S-heat, osmo-shock, salt-shock or oxidative stress. causal...
Initial exposure of plants to osmotic stress caused by drought, cold, or salinity leads acclimation, termed acquired tolerance, subsequent severe stresses. Acquired osmotolerance induced salt is widespread across Arabidopsis (Arabidopsis thaliana) accessions and conferred disruption a nucleotide-binding leucine-rich repeat gene, designated ACQUIRED OSMOTOLERANCE. De-repression this gene under causes detrimental autoimmunity via ENHANCED DISEASE SUSCEPTIBILITY1 PHYTOALEXIN DEFICIENT4 (PAD4)....
Acquired osmotolerance induced after salt stress is widespread across Arabidopsis thaliana (Arabidopsis) accessions (e.g., Bu-5). However, it remains unclear how this established. Here, we isolated a mutant showing an acquired osmotolerance-defective phenotype (aod2) from ion-beam-mutagenized M2 population of Bu-5. aod2 was impaired not only in but also osmo-shock, salt-shock, and long-term heat tolerances compared with Bu-5, displayed abnormal morphology, including small, wrinkled leaves,...
Adaptation and tolerance to changes in heat cold temperature are essential for survival proliferation plants animals. However, there is no clear information regarding the common molecules between animals plants. In this study, we found that heat, of nematode
Land plants have evolved a hydrophobic cuticle on the surface of aerial organs as an adaptation to ensure survival in terrestrial environments. Cuticle is mainly composed lipids, namely cutin and intracuticular wax, with epicuticular wax deposited plant surface. The composition permeability large influence its ability protect against drought stress. However, regulatory mechanisms underlying cuticular biosynthesis response stress not been fully elucidated. Here, we identified three AP2/ERF...

Abstract Calcium (Ca2+) is a major ion in living organisms, where it acts as second messenger for various biological phenomena. The Golgi apparatus retains higher Ca2+ concentration than the cytosol and returns cytosolic to basal levels after transient elevation response environmental stimuli such osmotic stress. However, transporters localized of plants have not been clarified. We previously found that wild-type (WT) salt-tolerant Arabidopsis (Arabidopsis thaliana) accession, Bu-5, showed...
