摘要

The semidwarf phenotype has been extensively selected during modern crop breeding as an agronomically important trait In troduction of the semidwarf gene, semi-dwarf1 (sd1). which encodes a gibberellin biosynthesis enzyme, made significant contributions to the "green revolution" in rice (Oryza sativa L). Here we report that SD1 was involved not only in modern breeding including the green revolution, but also in early steps of rice domestication. We identi fied two SNPs in O. sativa subspecies (ssp.) japonica SD1 as functional nucleotide polymorphisms (FNPs) responsible for shorter culm length and low gibberellin biosynthetic activity. Genetic diversity analysis among O. sativa ssp. japonica and indica. along with their wild ancestor O. rufipogon Griff, revealed that these FNPs clearly differentiate the japonica landrace and O. rufipogon. We also found a dramatic reduction in nucleotide diversity around SD1 only in the japonica landrace, not in the indica landrace or p. rufipogon. These findings indicate that SD1 has been subjected to artificial selection in rice evolution and that the FNPs participated in japonica domesti cation, suggesting that ancient humans already used the green revolution gene.
