WebApr 11, 2024 · Expression of mutant human amyloid protein in animals results in deposits of Aβ plaques that induce abnormal increases in neuronal activity and impair the normal function of neuronal circuits. ... The failure of cryb mutants to synchronize to light dark cycles indicates that cryptochrome’s normal function involves circadian photoreception. WebSep 30, 2024 · In brief, the embryos were injected with Cas9 mRNA and gRNA targeting the first exon of the cryptochrome gene. The mutant founder animal was identified in the F1 generation by PCR and the mutation verified by sequencing.
The Arabidopsis cryptochrome 2 I404F mutant is hypersensitive …
WebJan 31, 2013 · The mutant mice and fruit flies show distinct signs of early aging and have a reduced lifespan compared to the normal counterparts. The tissues of Bmal1 −/− mice and brains of per 01 fruit flies also show a high accumulation of ROS, which is consistent with the idea that Bmal1 or per (in case of fruit flies) participates in oxidative stress ... WebNov 20, 2007 · Cryptochrome blue-light receptors mediate many aspects of plant photomorphogenesis, such as suppression of hypocotyl elongation and promotion of cotyledon expansion and root growth. The cryptochrome 1 (cry1) protein of Arabidopsis is present in the nucleus and cytoplasm of cells, but how the functions of one pool differ … the process of erection
SUB1, an Arabidopsis Ca2+-Binding Protein Involved in Cryptochrome …
WebWe investigated this hypothesis by analyzing the photochemical and physiological activities of Arabidopsis cryptochrome 2 (CRY2) mutations altered in each of the three trp-triad residues. We found that all trp-triad mutations of CRY2 tested lost photoreduction activity in vitro but retained the physiological and biochemical activities in vivo. WebSep 21, 2024 · Similar maxima were also observed for mutant cry1cry2 irrespective whether or not the seedlings were raised in darkness or blue light (Fig. 6b). Even though the stimulus–response curves of cry1cry2 were somewhat irregular, it became apparent that the cryptochrome mutant had still retained responsiveness to MFs. WebWe have identified an Arabidopsis photomorphogenic mutant, sub1 , which exhibits hypersensitive responses to blue light and far-red light. Genetic analyses indicate that SUB1 functions as a component of a cryptochrome signaling pathway and as a modulator of a phytochrome signaling pathway. The SUB1 gene encodes a Ca 2+ -binding protein that ... signalled agreement
