Indispensable roles of Mr-abaA in blastospore separation. (A) Blastospore yields were quantified from 4-day-old submerged cultures of WT and ΔMr-abaA strains in SDB medium and PPD medium, respectively. No detectable (N) blastospores were observed for the ΔMr-abaA strain. **, P < 0.01, Tukey’s HSD tests. (B) In submerged broth in vitro, the WT strain formed blastospores (B), while the ΔMr-abaA strain generated abnormal blastospores (AB). Error bars in panel A indicate standard deviations of the means from three independent replicates.
