Abstract:

Rice (Oryza sativa) is not only the staple food for more than half of the world's population but also a model species for plant developmental and genetic studies. To meet the challenge of feeding an increasing population, breeding for high-yield varieties has always been an ultimate goal for rice breeders. Before the era of molecular biology, breeders identified a semi-dwarf mutation (sd1) in the 1950s, and its application contributed to the first “green revolution”, which helped to alleviate food shortage in 19 developing countries.
