Resumen: DASH (Drosophila, Arabidopsis, Synechocystis, human) cryptochromes (cry-DASHs) constitute a subgroup of the photolyase cryptochrome family with diverse light-sensing roles, found in most taxonomical groups. The genome of Fusarium fujikuroi,a phytopathogenic fungus with a rich secondary metabolism, contains a gene encoding a putative cry-DASH, named CryD. The expression of the cryD gene is induced by light in the wild type, but not in mutants of the “white collar” gene wcoA. Targeted acryD mutants show light-dependent phenotypic alterations, including changes in morphology and pigmentation, which disap- pear upon reintroduction of a wild-type cryD allele. In addition to microconidia, the colonies of the acryD mutants produced under illumination and nitrogen starvation large septated spores called macroconidia, absent in wild-type colonies. The acryD mutants accumulated similar amounts of carotenoids to the control strain under constant illumination, but produced much larger amounts of ...
