Brasília, DF: Sociedade Brasileira de Fitopatologiac2023  ap. 680.  aPolymyxa graminis, a protozoan classified in the family Plasmodiophoraceae, is a widely distributed microorganism and obligate parasite that primarily infects the roots of various cereal and wild grass species. While not considered a typical plant pathogen, it serves as an efficient vector for over 14 soil-borne viruses classified in the families Benyviridae, Potyviridae and Virgaviridae. The objective of this study was to molecularly characterize P. graminis isolates associated with wheat and rice in southern Brazil.  aArroz  aDoença de Planta  aOryza Sativa  aPolymyxa Graminis  aTrigo  aTriticum Aestivum  aDiversidade genética  aGenetic diversity1 aNASCIMENTO, S.
