摘　　要：真菌通过光受体感受光信号,光除了调控大型真菌生理周期、形态变化和代谢产物产生外,还是大多数大型真菌原基分化和子实体生长的必要条件。本文对近年来大型真菌的光反应和光受体研究进行了概述。大型真菌中光受体研究目前仅限于WC‐1同源蛋白,WC‐1既有对光信号应答的能力,同时作为转录因子,又能激活下游基因的表达,但是不同物种中可能存在不同的靶基因。wc‐1基因敲除造成裂褶菌、蛹虫草子实体发育阻断。光受体及其作用机制的研究将为大型真菌子实体发育机制研究奠定基础。Light plays important roles in the growth and development of fungi. It can regulate the circadian rhythm, morphology and secondary metabolite of macrofungi and is essential for the formation and development of primordium and fruiting body Fungi sense light signal through photoreceptors. WC-1, the blue light receptor, is the only photoreceptor studied in macrofung so far. WC-1 can response to light signal and stimulate the expressions of downstream genes which may differ in different species as a transcription factor. The deletion of wc-1 in Schizophyllurn commune and Cordyceps rnilitaris results in blocking of fruiting body development. The study on photoreceptors and their mechanisms will improve the understanding the fruiting body development in macrofungi. In this paper, we summarized the research progresses on photo responses and photoreceptors reported in macrofungi in recent years
