Control of grain size in rice
WebApr 24, 2024 · Grain size is one of the key agronomic traits that proceeded from unconscious selective pressure over the course of rice domestication. Improving grain size as an early adaptive response to rice cultivation is a result of unintentional selection for seeds that could survive even with deeper soil cultivation ( Purugganan and Fuller, 2009 ).

WebMar 10, 2024 · In general, the final size of rice grains is coordinately controlled by cell proliferation and cell expansion in the spikelet hull, which sets the storage capacity of the grain and limits grain filling. Recent studies have identified several quantitative trait loci and a number of genes as key grain size regulators.
Web1 day ago · Under the DA 2024 supply outlook, the country’s total supply is at 16.98 million metric tons (MMT), which is sufficient to cover this year’s demand estimated at 15.29 MMT. “This would leave the country with an ending balance of 1.69 MMT, which is equivalent to 45 days of buffer stock, instead of the 90-day ideal buffer stock to stabilize ... WebNov 10, 2024 · Heterotrimeric GTP binding proteins (G proteins) and cytokinin play important roles in regulating plant growth and development.
