A spheroplast-like "slime" mutant of Neurospora crassa (lacking a rigid cell wall) was found to synthesize an identical spectrum of carotenoids as wild type strains except for beta-carotene. Furthermore strict photoregulation of the biosynthesis of these pigments as well as the characteristics of photoinduced carotenogenesis were also nearly identical in the mutant and in the wild type.
人们发现，粗糙脉孢菌的一种类原生质体“黏液”突变体（缺乏坚硬的细胞壁）除了β-胡萝卜素外，合成的类胡萝卜素光谱与野生型菌株完全相同。此外，这些色素生物合成的严格光调节以及光诱导类胡萝卜素生成的特征在突变体和野生型中也几乎相同。
