Cryptochrome signaling
WebMar 31, 2024 · Cryptochromes (CRY) are flavoproteins that share an exciting evolutionary history with DNA repair enzymes, DNA photolyases. The first published cryptochrome sequences were from plants and have subsequently been found in many other groups of organisms including mammals. WebApr 10, 2024 · Temperature affects many aspects of plant growth and development through a complex network of transcriptional responses. Although temperature sensing is a crucial primary step in initiating transcriptional responses via Ca 2+ and/or reactive oxygen species signaling, an understanding of how plants perceive temperature has remained elusive ...
