| Research Abstract |
Whole rice genome, which transposon content is 35 %, was sequenced with high accuracy and informative for transposon research. An active rice transposon nDart1-0 element was identified as a causative element for the mutable virescent line that shows green sectors in the virescent yellow leaves. The transposition of nonautonomous nDart1-0 element requires transposase supplied from an autonomous aDart1-27 element. An introduced aDart1-27 element from other variety by crossing has kept the active state. However, a hybrid line obtained by interspecific cross between an African wild rice species, Oryza longistaminata, and a mutable virescent line showed the only green leaf phenotype even though it carried both the nDart1-0 and aDart1-27 elements. Genetic analysis indicated the inhibition of nDart1-0 transposition was caused by a factor derived from Oryza longistaminata. It was revealed that the inhibitory factor regulated transposase mRNA in a posttranscriptional manner
