HY5-COP1 interaction mediates cross-talk among multiple pathways, thereby, enhancing the phenotypic plasticity of plants. This interaction regulates not only the upstream components of light signaling pathway like photoreceptors but also regulates a number of downstream effectors and early signaling ...

摘要 植物光形态建成调控因子COP1黑暗中积累在细胞核内,直接与碱性亮氨酸拉链(bZIP)类转录因子HY5相互作用,并被蛋白酶降解,负调控下游基因的表达;而在光下COP1从细胞核内转移到细胞核外,HY5得以在细胞核内积累,可特...展开更多 COP1 (constitutively photomorphogenic 1) accumulates in the nucleus in the dark...
Moreover, ABI4 and HY5 antagonistically regulate the expression of CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) and the subsequent greening process. In turn, ABI4 and HY5 are targeted for degradation by COP1 in the light and dark, respectively, to ensure a proper interplay of ABI4 and HY5 actions...
Molecular interaction between COP1 and HY5 defines a regulatory switch for light control of Arabidopsis development. Arabidopsis COP1 acts as a light-inactivable repressor of photomorphogenic development, but its molecular mode of action remains unclear. Here, we show that COP1 negatively regulates ...
[福建十一校2024联考]SPA1和COP1是参与拟南芥光反应调控的蛋白质,HY5是转录因子。 在黑暗中生长的拟南芥幼苗通常表现为黄叶,称为黄化苗。 光照影响拟南芥幼苗叶色的分子机制如图所示。 下列分析正确的是()黑暗环境下光照环境下细胞质基质细胞质基质光敏色素光敏色素细胞核细胞核SPAD COPD作用SPAD COPD HY5→降解HYS幼...
The UV-B-inducible expression pattern and its suppression of HY5 activity suggest that BBX24 could be a new component of the feedback regulatory module of UV-B signaling in plants. Keywords: UV-B; photomorphogenesis; STO/BBX24; COP1; HY5; Arabidopsis thaliana Cell Research (2012) 22:1046...
在黑暗中生长的植物幼苗的叶片表现为黄色,称为黄化苗。SPA1和COP1是植物光信号转导调控过程中的重要物质,HY5是细胞核内的一类转录因子。光照影响幼苗叶色的分子机制如图所示。下列叙述错误的是( ) A.在黑暗环境下培养的黄化苗,再转入光照环境下培养,可以恢复原本的颜色 ...
