Abstract:

The distribution and structure characteristics of blast resistance (R) genes on the rice physical and genetic maps have been gradually elucidated, as many blast R genes have been identified and cloned in recent years. These R genes are distributed on all of the rice genome except on chromosome 3.Among them, at least 24 R genes are located on chromosome 11. In this paper, we review the recent research progress on mapping and cloning of blast resistance genes in rice. In particularly, we focus on the distribution and structure characteristics of blast R genes and resistance gene analogues located on chromosome 11. Exploitation and application of new R genes on rice blast resistance breeding by marker aided selection is also discussed.
