| Title: Molecular cloning of Sdr4 , a regulator involved in seed dormancy and domestication of rice .
| | Author: Sugimoto K Takeuchi Y Ebana K Miyao A Hirochika H Hara N Ishiyama K Kobayashi M Ban Y Hattori T Yano M | | Journal: Proc Natl Acad Sci U S A Citation: V : 107 P : 5792-7 Year: 2010 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub20220098 Accession (PMID): 20220098 | | Abstract: Seed dormancy provides a strategy for flowering plants to survive adverse natural conditions .
It is also an important agronomic trait affecting grain yield , quality , and processing performance .
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 .
Srd4-k also is found in the wild ancestor Oryza rufipogon , whereas Sdr4-n appears to have been produced through at least two mutation events from the closest O rufipogon allele among the accessions examined .
These results are discussed with respect to possible selection of the allele during the domestication process .
