Hsfa2 cry1
WebCRY1 and CRY2 proteins are highly conserved components of the circadian clock that controls daily physiological rhythms. Disruption of CRY functions are related to many diseases, including circadian sleep phase disorder. Web9 dec. 2015 · HSFA2 was reported to be required for the maintenance of high expression levels of several HS memory-related genes, but not for their induction, suggesting they could be direct targets of HSFA2 (Nishizawa et al, 2006; Charng et al, 2007 ). This idea was confirmed by in vitro binding studies (Schramm et al, 2006 ), but so far not in planta.

Its expression is suppressed in the HSFA1a knockdown tomato …
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. Web29 aug. 2024 · To test this hypothesis, we compared hypocotyl elongation of cry1 and pif mutants in response to 21FR, 30WL, and 30FR. We found that pif7 suppressed the long …

Web6 sep. 2024 · In hsfa2 mutants, the duration of AT was compromised, and the expression of HS-inducible genes was down-regulated. Lämke et al. reported that HSFA2 promotes the sustained activation of several HS-memory genes through methyla-tion of the target genomic region [32]. The transcripts of HSFA2 are undetectable under normal conditions.
