Description Rymv1 locus, controlling the high recessive resistance to rice yellow mottle virus (RYMV), was mapped to a 160-kb interval containing a gene from the elF(iso)4G family. Transformation of a resistant line with a elF(iso)4G cDNA, isolated from a susceptile variety, resulted in the loss of resistance in stable transgenic plants. Analysis of Rymv1 allelic variability from susceptible and resistant varieties show amino acid change in the MIF4G domain of elf(iso)4G translation initiation factor confers high resistance to RYMV, this suggests that this domain may be involved in the interaction with the virus.
Curator Comment The cDNA of the candidate genes was sequenced in the O. sativa varieties IR64 (AM156957), Gigante (AM156958) and in O.glaberrima varieties Tog5681 (AM156959), Tog5672 (AM156961), Tog5673 (AM156960). IR64 and Tog5673 are susceptible, the rest are resistant to rice yellow mottle virus.
In rice there is another gene RYMV (GR:0061133), present on chr-12 that also confers resistance to rice yellow mottle virus.
