Research Abstract

cDNA sequences are generated by an efficient analysis system and aligned with full length cDNA sequences of Haruna Nijo to develop genome wide SNP detection system. The array system is used to genotype recombinant inbred lines and recombinant chromosome substitution lines for genetic map development and estimation of substitution segments. Salt tolerance of these lines are evaluated to map tolerance QTLs and their responsible substitution segments. On the other hand, a previously isolated tolerance gene by subtraction method is used to make transgenic plant to evaluate its salt tolerance. Markers are also developed to narrow down tolerance genes. The recombinant chromosome substitution liens carrying tolerance gene segments are developed to be used as isogenic lines for salt tolerance.
