Abstract: | UV-A* irradiation caused increases in total protein in Fusariumsolani, while its effect on Alternaria alternata was variable,and not as clear-cut as in F. solani. On the other hand, UV-Birradiation stimulated protein production in both fungi. UV-Airradiation showed an inhibitory effect on total DNA in bothfungi, while the effect on RNA was stimulatory in F. solanibut had no effect on A. alternata. Short fluences of UV-B inhibitedDNA production to some extent in both fungi, however longerfluences increased DNA content especially in F. solani. Theeffect of UV-B on RNA production was inhibitory in F. solanibut not in A. alternata. A. alternata is much more resistantto UV-irradiation than is F. solani, and increases in proteinin the former after UV-irradiation suggests that protein mayplay a part in protection against the harmful effect of UV-irradiation.
