Genetic 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 کاملOsGRF4 controls grain shape, panicle length and seed shattering in rice
Traits such as grain shape, panicle length and seed shattering, play important roles in grain yield and harvest. In this study, the cloning and functional analysis of PANICLE TRAITS 2 (PT2), a novel gene from the Indica rice Chuandali (CDL), is reported. PT2 is synonymous with Growth-Regulating Factor 4 (OsGRF4), which encodes a growth-regulating factor that positively regulates grain shape and...

such as rice to weedy or red rice (Oryza spp.) (Oard et al., 2000; Gealy et al., 2003; Zhang et al., 2003). SystemSeed dormancy, a major adaptive trait in plants, facilitates the atic research is required to understand how seed dorsurvival of weeds and provides for resistance to preharvest sprouting (PHS) in cereal crops. Seventeen weedy strains and 24 cultivars of mancy and other characteristi...
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...
متن کاملSHAT1, 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...
