WebCRY1 has been shown to work additively to the phototropins in a COP1-dependent way to regulate stomatal opening in response to blue light (Mao, Zhang, Sang, Li, & Yang, 2005) (Figure 8). In response to red light, phyB mediates stomatal opening in a COP1- or PIF3/PIF4-dependent way (Wang, Lian, Kang, & Yang, 2010). track flight qr1370WebMar 29, 2024 · The circadian clock and the hypoxia-signaling pathway are regulated by an integrated interplay of positive and negative feedback limbs that incorporate energy … track flight qr004We wish to understand different mechanisms governing the activities of COP1 and LRBs with respect to CRY2 ubiquitination.
