| Abstract: Rice tungro disease ( RTD ) is a serious constraint to rice production in South and Southeast Asia .
RTD is caused by Rice tungro spherical virus ( RTSV ) and Rice tungro bacilliform virus .
Rice cv .
Utri Merah is resistant to RTSV .
To identify the gene or genes involved in RTSV resistance , the association of genotypic and phenotypic variations for RTSV resistance was examined in backcross populations derived from Utri Merah and rice germplasm with known RTSV resistance .
Genetic analysis revealed that resistance to RTSV in Utri Merah was controlled by a single recessive gene ( tsv1 ) mapped within an approximately 200-kb region between 22 . 05 and 22 . 25 Mb of chromosome 7 .
A gene for putative translation initiation factor 4G ( eIF4G ( tsv1 ) ) was found in the tsv1 region .
Comparison of eIF4G ( tsv1 ) gene sequences among susceptible and resistant plants suggested the association of RTSV resistance with one of the single nucleotide polymorphism ( SNP ) sites found in exon 9 of the gene .
Examination of the SNP site in the eIF4G ( tsv1 ) gene among various rice plants resistant and susceptible to RTSV corroborated the association of SNP or deletions in codons for Val ( 1060-1061 ) of the predicted eIF4G ( tsv1 ) with RTSV resistance in rice .
