Abstract: The phylogenetic relationships of sugarcane grassy shoot phytoplasma strains to each other and to closely related phytoplasmas infecting mainly gramineous plant worldwide, at both 16S rRNA gene and 16S/23S rDNA spacer region sequence level were examined. Most of the rDNA sequences used were retrieved from GenBanks whereas additional sequences of two Indian strains were determined in this work. The sugarcane grassy shoot phytoplasma, which is known to be a member of the rice yellow dwarf (RYD) phytoplasma group or 16SrXI group, proved to be very closely related to the sugarcane white leaf agent. More distantly related to it, are sorghum grassy shoot phytoplasma, `Candidatus Phytoplasma oryzae' and `Candidatus Phytoplasma cynodontis'.
