WebJun 19, 2007 · FHY1 and FHL play crucial roles in phyA nuclear translocation and signaling. Thus the double-mutant fhl/fhy1 allows nuclear and cytoplasmic phyA functions to be separated, leading to the novel identification of cytoplasmic phyA responses. Publication types Research Support, Non-U.S. Gov't MeSH terms WebFHY1 transports the photoactivated phytochrome A into the nucleus. Here, we reveal that far-red light (FR)-induced SUMOylation of FHY1 promotes its degradation to desensitize …

WebMay 11, 2012 · FHY1 Phosphorylation Promotes Cytoplasmic Localization. (A) FHY1 localizes in the nucleus (top) or stays ubiquitously distributed (bottom). Onion epidermal cells expressing GFP-FHY1 by bombardment were incubated in the dark for 36 h followed by a 2-min white light pulse. The 4′,6-diamidino-2-phenylindole (DAPI)-stained nucleus is … WebNuclear accumulation of light-activated phyA requires FAR-RED ELONGATED HYPOCOTYL1 (FHY1) and FHY1-LIKE (FHL) (Liu and Wang, 2024). In addition, the first known positive regulator of light, the basic leucine zipper (bZIP) transcription factor, HY5, plays a role in transcriptional regulation downstream of RL and FRL, as well as in BL and … mouth air freshener
Reversible SUMOylation of FHY1 Regulates Phytochrome A
WebFHY1 encodes a product (FHY1) that specifically transduces signals downstream of the far-red (FR) light-responsive phytochrome A (PHYA) photoreceptor. We show that FHY1 is a … WebJul 12, 2014 · To determine which of the FHY1-associated genes are transcriptionally regulated by FHY1 (thereafter defined as FHY1 direct target genes), we performed an … WebAug 1, 2006 · fhy1-1 seedlings complemented with P 35S:FHY1-GFP, phyA-201 seedlings expressing the same construct, as well as L er and phyA-201 seedlings transformed with P 35S:YFP-FHL were grown for 3 d in the dark and analyzed directly (D) or irradiated for 6 h with far-red light followed by a 2 min white light pulse (6 h FR + W) prior to microscopy. … heartway venus mobility scooter
