Effects of MrUBI4 deletion on vegetative growth. (A) Colony phenotyping of the WT and mutant strains on PDA, SDAY, and 1/4 SDAY plates after growing for 10 days at 25 °C. Scale: 1 cm. (B) Fungal colony diameters of 3 different strains on PDA, SDAY, and 1/4 SDAY plates after growing for 10 days at 25 °C. (C) Fungal growth of 3 different strains during the 4-14 day cultivation period on PDA plates at 25 °C, and the growth rates of the ∆MrUBI4 strain reduced significantly (Tukey’s test, p < 0.01) after 4 days post-inoculation. **, p < 0.01. WT: wild-type strain, MT: ∆MrUBI4 strain, Comp: complementary strain.
