The present invention discloses an endophytic fungus FO-R20 and applications thereof, and belongs to the technical filed of microbial applications. The deposit number of the endophytic fungus FO-R20 is CCTCC M 2021505, and the scientific name thereof is. The present invention provides a novel endophytic fungal strain in the genus. Colonization of the endophytic fungus FO-R20 in the root tissues of rice can significantly improve the quality of rice seedlings and enhance the rice yields. The remarkable effect of symbiosis and interactions of the endophytic fungus FO-R20 on rice has huge value in the agricultural field by application and popularization thereof.

Endophytic falciphora oryzae FO-R20 and its application

The present invention discloses a method for improving cadmium tolerance in rice and reducing cadmium content in rice grains, and belongs to the technical field of microbial applications. In the present invention, an endophytic fungiFO-R20 with a deposit number of CCTCC M 2021505 is subjected to seedling co-raising with rice in a fungal fertilizer form, the endophytic fungiFO-R20 is colonized in the root tissue of rice, and then the rice seedlings are transplanted to a field until harvest. Therefore, the tolerance of rice to cadmium is improved, the content of heavy metal cadmium in the grains of rice is reduced by 12.61%. The FO-R20 has great value by popularization and application in guaranteeing plant health and improving crop quality.

Method for improving cadmium tolerance in rice and reducing cadmium content in rice grains

The present invention discloses an endophytic fungal strainsp. P-B313 and an application thereof, and belongs to the technical filed of microbial applications. The deposit number of the endophytic fungal strain P-B313 is CCTCC M 2021504, and the scientific name thereof issp. The endophytic fungal strain P-B313 can enhance the resistance of rice against seedling leaf blast with a control efficiency of 87.56% and a disease index reduced by 62.59. The biological control efficiency of the endophytic fungus P-B313 against seedling leaf blast in rice has great value by promotion and applications thereof in the field of agriculture.

Endophytic fungusP-B313 and its application

The present invention discloses an application of an endophytic fungi FO-R20 in prevention and treatment of rice neck or panicle blast, and belongs to the technical filed of microbial applications. TheFO-R20 with a deposit number of CCTCC M 2021505 is prepared into a seed coating agent or solid fungal fertilizer and applied to rice seeds; and in the culture process, the strain is colonized at the roots of rice, thus the disease resistance of rice to neck or panicle blast is remarkably enhanced, the prevention and treatment efficiency reaches 86.91%-90.85%, and the disease index is reduced by 64.92-72.07. The biological prevention and treatment effect of the endophytic fungiFO-R20 against rice neck or panicle blast has great value by promotion and applications thereof in the field of agriculture.
