Description:
Loss of seed shattering was a key event in the domestication of major cereals. We revealed that the qSH1 gene, a major quantitative trait locus of seed shattering in rice, encodes a BEL1-type homeobox gene and demonstrated that a single-nucleotide polymorphism (SNP) in the 5' regulatory region of the qSH1 gene caused loss of seed shattering owing to the absence of abscission layer formation. Haplotype analysis and association analysis in various rice collections revealed that the SNP was highly associated with shattering among japonica subspecies of rice, implying that it was a target of artificial selection during rice domestication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Konishi, Saeko -- Izawa, Takeshi -- Lin, Shao Yang -- Ebana, Kaworu -- Fukuta, Yoshimichi -- Sasaki, Takuji -- Yano, Masahiro -- New York, N.Y. -- Science. 2006 Jun 2;312(5778):1392-6.
