Nuclear localization of the Arabidopsis blue light receptor cryptochrome 2.
The cryptochrome blue light photoreceptor family of Arabidopsis thaliana consists of two members, CRY1 and CRY2 (PHH1). CRY2 contains a putative nuclear localization signal (NLS) within its C-terminal region. We examined whether CRY2 is localized in the nucleus and whether the C-terminal region of CRY2 is involved in nuclear targeting. Total cellular and nuclear protein extracts from Arabidopsi...
متن کاملCryptochrome 1, cryptochrome 2, and phytochrome a co-activate the chloroplast psbD blue light-responsive promoter.
The reaction center core of photosystem II is composed of two chlorophyll binding proteins, D1 and D2, that are encoded by the chloroplast genes psbA and psbD. These chlorophyll binding proteins are damaged during photochemistry, especially under high irradiance. Photosystem II function is maintained under these conditions through turnover and resynthesis of D1 and D2. Blue light-activated tran...
متن کاملPlant blue-light receptors.
Plants have several blue-light receptors, which regulate different aspects of growth and development. Recent studies have identified three such receptors: cryptochrome 1, cryptochrome 2 and phototropin. Cryptochromes 1 and 2 are photolyase-like receptors that regulate hypocotyl growth and flowering time; phototropin mediates phototropism in response to blue light. In addition, phytochrome A has...
متن کاملEnhancement of blue-light sensitivity of Arabidopsis seedlings by a blue light receptor cryptochrome 2.
Cryptochrome is a group of flavin-type blue light receptors that regulate plant growth and development. The function of Arabidopsis cryptochrome 2 in the early photomorphogenesis of seedlings was studied by using transgenic plants overexpressing CRY2 protein, and cry2 mutant plants accumulating no CRY2 protein. It is found that cryptochrome 2 mediates blue light-dependent inhibition of hypocoty...
متن کاملCryptochrome 1 contributes to blue-light sensing in pea.
Cryptochromes are widespread in higher plants but their physiological roles as blue-light photoreceptors have been examined in relatively few species. Screening in a phyA null mutant background has identified several blue-light response mutants in pea (Pisum sativum), including one that carries a substitution of a highly conserved glycine residue in the N-terminal photolyase-homologous domain o...
