Genetic control of inflorescence architecture during rice domestication.


ABSTRACT: Inflorescence architecture is a key agronomical factor determining grain yield, and thus has been a major target of cereal crop domestication. Transition from a spread panicle typical of ancestral wild rice (Oryza rufipogon Griff.) to the compact panicle of present cultivars (O. sativa L.) was a crucial event in rice domestication. Here we show that the spread panicle architecture of wild rice is controlled by a dominant gene, OsLG1, a previously reported SBP-domain transcription factor that controls rice ligule development. Association analysis indicates that a single-nucleotide polymorphism-6 in the OsLG1 regulatory region led to a compact panicle architecture in cultivars during rice domestication. We speculate that the cis-regulatory mutation can fine-tune the spatial expression of the target gene, and that selection of cis-regulatory mutations might be an efficient strategy for crop domestication.
