SHAT1, A new player in seed shattering of rice.
A major event in domestication of crops was the elimination of seed shattering, so that instead of falling to the ground, seeds stayed on the stalk until farmers could harvest them (Doebley, 2006). The SH4 (for grain shattering quantitative trait locus on chromosome4) and qSH1 (for quantitative trait locus of seed shattering on chromosome1) transcription factor genes are known to play key roles...
متن کاملEffect of quantitative trait loci for seed shattering on abscission layer formation in Asian wild rice Oryza rufipogon
Asian cultivated rice Oryza sativa L. was domesticated from its wild ancestor, O. rufipogon. During domestication, the cultivated rice lost its seed-shattering behaviour. Previous studies have shown that two major quantitative trait loci (QTLs; qSH1 and sh4) are responsible for the seed-shattering degree. Here, we produced introgression lines carrying non-functional alleles from O. sativa 'Nipp...
متن کاملGenetic control of seed shattering in rice by the APETALA2 transcription factor shattering abortion1.
Seed shattering is an important agricultural trait in crop domestication. SH4 (for grain shattering quantitative trait locus on chromosome 4) and qSH1 (for quantitative trait locus of seed shattering on chromosome 1) genes have been identified as required for reduced seed shattering during rice (Oryza sativa) domestication. However, the regulatory pathways of seed shattering in rice remain unkn...
متن کاملDetection of SNPs between Tainung 67 and Nipponbare rice cultivars
Single nucleotide polymorphisms (SNPs) are known as the most detectable variations among related genomes. We estimated the SNPs between Tainung 67 (TNG67), an elite cultivar of rice (Oryza sativa) in Taiwan, and Nipponbare, the cultivar used for rice genome sequencing by the international consortium. More than 6,000 expressed sequence tag (EST) sequences from developing panicles of TNG67 were c...
متن کاملAn SNP caused loss of seed shattering during rice domestication.
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. Ha...
