Abstract:

Asian cultivated rice has been domesticated from ancestors of the wild rice species Oryza rufipogon. During this process, important changes have occurred in many agronomic traits, such as plant height, grain shattering, and panicle shape, and the yield has also greatly increased. However, many favored traits (e.g., stress resistance) have been lost. The genome of O. longistaminata is of the same AA type as O. sativa, harboring many genes conferring resistance to biotic and abiotic stresses, and it is considered as a potential gene pool for genetic improvement of O. sativa. In this review, we summarize the basic research on O. longistaminata, including its resistance to biotic and abiotic stresses, its rhizome traits, and other traits that are of potential application value, such as bacterial blight resistance, drought resistance, heat tolerance, self-incompatibility, nitrogen efficiency, and high yield. Furthermore, we present the current applied research progress on perennial rice breeding based on the rhizome trait of O. longistaminata. Lastly, the possibility of de novo domestication of O. longistaminata is discussed. We expect this article to provide information to enhance the basic research of O. longistaminata and accelerate the genetic improvement of cultivated rice.

Key words: Oryza longistaminata, favorable genes, perennial rice, genome editing, de novo domestication
