Genetic analysis showed that the pif4 or pif4pif5 mutant is epistatic to the cry1 mutant, ... WebJan 19, 2001 · Cryptochromes and phytochromes are the major photosensory receptors in plants and often regulate similar photomorphogenic responses. The molecular mechanisms underlying functional interactions of cryptochromes …
In plants, cryptochromes mediate phototropism, or directional growth toward a light source, in response to blue light. This response is now known to have its own set of photoreceptors, the phototropins. Unlike phytochromes and phototropins, cryptochromes are not kinases. Their flavin chromophore is reduced by light and transported into the cell nucleus, … WebDec 1, 2000 · Cryptochrome mediates light input to the clock in Drosophila, exhibiting a light-dependent interaction with one of the molecules making up the clock mechanism …
WebHowever, the role of tomato (Solanum lycopersicum L.) cryptochrome 1a (cry1a) in the blue light fluence-dependent modulation of the water deficit response remains largely elusive. The tomato cry1a mutant and its wild-type counterpart were grown in water (no stress) or PEG6000 (osmotic stress) treatments under white light (60 μmol m-2 s-1) or ... 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.
