Phycomyces blakesleeanus colour mutants of a new class have been isolated. The mutants form red mycelia when grown in the dark and show vegetative segregation. The affected gene, amedcarE, behaves as an extranuclear genetic factor. The red phenotype ofcarE mutants is caused by the accumulation of β-carotene in a form showing spectral shift to longer wavelengths. The spectral shift is abolished in vitro by heat or protease treatment and in vivo by the presence of light or retinol.
已分离到新类别的泡盛曲霉颜色突变体。这些突变体在黑暗中生长时形成红色菌丝体，并表现出营养体分离。受影响的基因 carE 表现为核外遗传因子。carE 突变体的红色表型是由β-胡萝卜素的积累引起的，其形式表现出向较长波长的光谱位移。该光谱位移在体外可被热或蛋白酶处理消除，在体内可被光或视黄醇消除。
