Abstract | This study sought a better understanding of the mechanism of the near-ultraviolet inhibition of microsclerotia and pigment formation in the fungus Verticillium albo-atrum Reinke & Berth. by observing changes which occur in certain major biochemical components: lipids, chitin, RNA, DNA, protein carbohydrates, and pigment. The most important finding was that dark-reared, microsclerotia-producing cultures generally produced about twice as much total lipid as did UV-reared cultures which produced no microsclerotia. At least part of the time, the carbohydrate content of the dark-reared cultures exceeded the carbohydrate content of the UV-reared culture s. The percent apparent protein (measured by the Lowry technique) in the dark-reared cultures declined with age from 25% to 8% by the eleventh day. The apparent protein content of the UV-reared cultures remained between 17-25%. No substantial differences in percent chitin and percent DNA of dark-reared and UV-reared cultures were observed. |
