Red yeast antagonist Rhodotorula rubra strain TG-1 was isolated from the tissue of sample rice plant in Uzbekistan. Strain TG-1 was transferred into plant vascular system by stem inoculation into rice plant. The antimicrobial activity of strain TG-1 against several pathogenic fungal and bacterial plant pathogens, including Fusarium genus strains and Xanthomonas malvacearum strains were determined. The combination of yeast strain TG-1 as a pathogens antagonist and the exfoliated vermiculite is able to increase the growth stimulating property on the cotton seed, and protect the plant from diseases. From the red pigmented TG-1 strain, was isolated non-pigmented stable mutant, which acquired yeast vigor ability. Plant tissue may emerge as a potential source for novel endophytes with a broad spectrum of inhibitory activity against pathogens.
