Web17 mrt. 2024 · Tango between Ethylene and HSFA2 Settles Heat Tolerance The phytohormone ethylene has roles in senescence, fruit ripening, and biotic and abiotic stress responses. However, the detailed mechanism (s) by which ethylene affects the plant heat stress response (HSR) is not well understood. Web6 apr. 2024 · CBF genes are rapidly and highly induced by low temperatures, and their encoded proteins activate the expression of COR ( COLD REGULATED) genes, leading to the accumulation of protective substances such as osmolytes and cryoprotective proteins that facilitate cold acclimation and freezing tolerance ( Thomashow, 1999, Shi et al., 2024 ).

Different studies have indicated that AS of these key HSFs is important for acclimation of plants to adverse high-temperature environments.
Webthat HSFA2 is the most highly heat-induced HSF and hsfa2 KO mutants are the only simple mutants which are completely unable to acquire thermotolerance. This is partly explained by the fact that HSFA2 is able to induce its own expression. However, the mechanism is not specific to HSFA2 as other HSFs can also exert positive feedback on other HSFs.
Web22 okt. 1999 · We conclude that CRY1 and CRY2 are circadian clock components that negatively regulate Per1 transcription independently of light. Our work indicates that they inhibit CLOCK-BMAL1 transactivation activity, very likely by means of direct contacts between CRY1 and BMAL1 and between CRY2 and CLOCK. knust acceptance formsWebof expression constructs in combinations of HsfA1 and HsfA2 by titration of either HsfA1 expression against a constant amount of HsfA2 or vice versa.
