Abstract

We have cloned the al-2 gene of Neurospora crassa and have analyzed its structure and regulation. The gene encodes a 603-residue polypeptide with a segment homologous to prokaryotic and other eukaryotic phytoene synthases. RNA measurements showed that the level of al-2 mRNA increased over 30-fold in photoinduced mycelia compared with dark-grown mycelia. This observation is consistent with the fact that carotenoid biosynthesis is induced by blue light during growth of N. crassa mycelia. The photoinduced increase in al-2 mRNA levels was not observed in two Neurospora mutants, wc-1 and wc-2, that are defective in all physiological photoresponses.
