- Publication
- Molecular cloning of Sdr4, a regulator involved in seed dormancy and domestication of rice, 2010, Proc Natl Acad Sci U S A.
- Sdr4 dominates pre-harvest sprouting and facilitates adaptation to local climatic condition in Asia cultivated rice., 2022, J Integr Plant Biol.
- Genbank accession number
- Key message
- We cloned a rice quantitative trait locus, Sdr4, which contributes substantially to differences in seed dormancy between japonica (Nipponbare) and indica (Kasalath) cultivars
- Sdr4 expression is positively regulated by OsVP1, a global regulator of seed maturation, and in turn positively regulates potential regulators of seed dormancy and represses the expression of postgerminative genes, suggesting that Sdr4 acts as an intermediate regulator of dormancy in the seed maturation program
- Japonica cultivars have only the Nipponbare allele (Sdr4-n), which endows reduced dormancy, whereas both the Kasalath allele (Srd4-k) and Sdr4-n are widely distributed in the indica group, indicating prevalent introgression
- Molecular cloning of Sdr4, a regulator involved in seed dormancy and domestication of rice
- Furthermore, like the semi-dwarf 1 (SD1) and Rc loci, Sdr4 underwent selection during the domestication and improvement of Asian cultivated rice
- Moreover, these findings provide guidance for utilizing the favorable alleles of Sdr4 and Rc to synergistically boost PHS resistance, yield, and quality in modern rice varieties
