Abstract

Sexual and asexual differentiation of are influenced by nitrogen availability and blue light. Nitrogen limitation induces the production of protoperithecia on solid medium and conidia in liquid medium. Both developmental processes are stimulated by blue light. We have analysed changes in mRNA levels for a variety of light-inducible genes ( and ) under conditions of nitrogen limitation. We show that the photoregulated genes and are also regulated by nitrogen limitation. These genes exhibited nitrogen regulation in the nonphotoresponsive mutant strains and . Therefore, the and gene products, although necessary for photoregulation of these and genes, are not required for nitrogen regulation.
