The recessive 'tall rice' phenotype associated with the mutation eui (elongated upper-most internode) is an important agronomic trait that has been introduced into hybrid rice to eliminate panicle enclosure in all types of male-sterile lines and produce good-quality seeds in high yield and at low cost. Based on our previous Eui mapping data, we conducted fine-structure mapping and positional cloning of the gene using an F2 population comprising more than 5000 individuals derived from a cross of the near-isogenic lines 307T (eui/eui) with the recurrent parent Zhenshan 97 (Eui/Eui). In total 45 CAPS (cleaved amplified polymorphic sequences) markers located within an interval of 14.5 cM were analyzed in the subpopulation of 1298 homozygous recessive plants. The resulting high-resolution map defined a 98-kb interval containing the Eui locus flanked by the markers M0387 and M01, and three markers were found to co-segregate with Eui. In order to facilitate the identification of the Eui gene, we used a transformation-competent artificial chromosome (TAC) vector to construct a set of contiguous TAC clones from the Nipponbare BACs (obtained from the Clemson University Genome Institute; CUGI) spanning this region. These clones can be used to streamline complementation testing. The markers tightly linked to the Eui locus can also be used in breeding male-sterile lines with the elongated uppermost internode.
