  • The recessive gene rymv-1, responsible for the high resistance of Oryza sativa 'Gigante' to Rice yellow mottle virus (genus Sobemovirus), was overcome by the variant CI4*, which emerged after serial inoculations of the non-resistance-breaking (nRB) isolate CI4. By comparison of the full-length sequences of CI4 and CI4*, a non-synonymous mutation was identified at position 1729, localized in the putative VPg domain, and an assay was developed based on this single-nucleotide polymorphism. The… CONTINUE READING
