| Abstract | ||||
| False smut disease of rice, incited by Ustilaginoidea virens (Cooke) Takah. is regarded as new and important disease in the recent years in Egypt. Investigations were carried finely to find out its impact on grains components, as well as ustiloxin production, by the fungus. Reduction of both tested amino and fatty acids contents has been observed in the infected grains. Certain fatty acides i.e., myristic, stearic, arachidic, behenic, and linolenic were decreased by 9.06%, while palmitic, palmitoleic and oleic were increased by 8.21%. The most dramatic observation was the increase of four amino acids namely, glycine, alanine, valine and isoleucine contents by 15.38% in molded smutted grains compared with healthy ones, which showed its corelation with fungal ustiloxins formation. | ||||
