We have recently shown that acquisition of a 6. 4-kb. double-stranded (ds) RNA (M1) by hyphal anastomosis is associated with enhanced vigor and virulence. whereas its removal by hyphal tipping correlates with diminished virulence in the plant-pathogenic basidiomycete Rhizoctonia solani. https://allfixelectricales.shop/product-category/water-dispenser-lever/
