真菌光受体及其功能研究进展
dvaces in Fungal Photoreceptor Study
光是环境中的重要信号因子,可以影响真菌的生长发育、生理周期、生殖和繁殖以及各种代谢活动。真菌对光信号感应的核心物质基础是各种发光色团,这是一类低分子量的有机分子,如黄素,视黄醛,线性四吡咯,它们分别与感受蓝、绿和红光有关。蓝光受体White collar 1和White collar 2是真菌中保守存在的一类光感受体,近年来在多种真菌中都对其有深入的研究,二者作为转录因子,它们依赖黄素发光色团感受到光信号的作用之后,能影响真菌下游基因的表达,进而从分子层面调控真菌的各种生命活动。真菌中还存在视蛋白,光敏色素,VIVID和隐花色素等光受体,但它们对真菌的光生物学意义还有待进一步阐明。许多真菌能侵染人类或动、植物,并造成病害,也有许多真菌是人类生产生活不可缺少的有益菌种,因此了解真菌的感光机制,进而对真菌光生物学机理的研究,将会为控制病原真菌的危害及合理开发有益真菌的经济价值提供新的思路。
Light is one of the most important environmental factors for almost all organisms. In fungi, varied physiological and metabolic processes, including vegetative growth and development, biological clocks entrainment, sexual or asexual reproduction, can be affected by light. The basic mechanism for light sensing in fungi derives from the photo receptors they possess, and the core of all receptor types is a chromophore, such as flavin, retinal, or linear tetrapyrrols for blue-, green-, or red-light sensing, respectively. Whereas the blue-light response via the conserved White collar complex (White collar 1 and 2) in fungi is one of the best-studied light responses, all other light-sensing mechanisms, such as opsins, phytochromes, VIVID and cryptochromes, are less well studied. On account of the fact that fungi can either play as pathogens both plant and animals or provide beneficial materials to humans, understanding light-sensing in fungi should be of practical interest in the future.
