In this paper we describe the light-regulated expression of albino-3 (al-3), a carotenoid biosynthetic gene of Neurospora crassa, in the wild-type strain. Our results suggest that the al-3 gene expression is regulated by the transcriptional activation of the gene and the low stability of its mRNA. The activation of the al-3 gene does not require protein synthesis to occur. The kinetic analysis of the al-3 mRNA reveals that the gene is transiently expressed even in continuous light, suggesting the presence of an adaptative process.
在本文中，我们描述了野生型菌株中粗糙脉孢菌类胡萝卜素生物合成基因白化病-3（al-3）的光调节表达。我们的结果表明，al-3基因表达受该基因的转录激活及其mRNA的低稳定性调控。al-3基因的激活不需要蛋白质合成的发生。对al-3 mRNA的动力学分析表明，即使在持续光照下该基因也会短暂表达，这表明存在一个适应性过程。
