摘要: Tillering is one of the most important agronomic traits of rice. In order to explore the molecular mechanism of rice tillering, a high-tillering dwarf 1-2 (htd1-2) mutant was isolated from the offspring of the indica rice (Oryza sativa L. ssp. indica) variety 9311 treated with 350Gy 60Co gamma-radiation. Genetic analysis showed that both high tillering and dwarf phenotypes of htd1-2 were controlled by a single recessive nuclear gene. By means of molecular marker technique, the HIGH-TILLERING DWARF1-2 (HTD1-2) gene was mapped …
