FIG 3.

Relative expression across sexual development of genes annotated as functioning in perithecial development. (A) Expression of asd-1 (ascus development) at 72 h, when asci first form. (B) Peaks of expression for the genes asd-3, asd-4, asl-1 (ascospore lethal), and asm-1 (ascospore maturation) during intermediate stages of sexual development. (C) Expression of r (round spore) and acon-3 during perithecial development. (D) Expression of meiosis gene mei-3 and female and male fertility gene fmf-1. (F) Correlated expression of app (abundant perithecial protein), per-1 (perithecial-1), and meiosis-specific gene Spo11 during sexual development.
