Abstract

In an effort to clone a rice blast resistance gene, Pi-2(t), a BAC contig consisting of 22 BAC clones covering the whole Pi-2(t) region, was constructed using marker-based chromosome landing and chromosome walking. The genetic span of this physical map is 8 cM, but the physical size is 925 kb. The physical map forms the base of further isolation and cloning of Pi-2(t) gene, it will provide new markers for molecular marker-aided selection of new blast resistance materials in rice.
