FIG 2 .

Wild-type and phytochrome knockout strains all respond dynamically to light, but respond differently, especially for genes involved in sexual reproduction. Disruption of phytochromes affected expression of early sexual development genes in response to light but did not markedly affect expression of conidiation genes. (A) The conidiation genes con-6, con-8, and con-10, showed similar expression profiles among wild-type and mutant strains. (B) Highly correlated upregulation of expression of sexual development-related genes occurred immediately following light stimulation in the Δphy-2 KO strain. The log₂ ratio of expression level was estimated based on analysis of microarray data (7). Expression is depicted under conditions of constant darkness (D) and following light exposure (5 to 240 min [LL5 to LL240]).
