WebSep 10, 2015 · Rice grain filling is a highly complicated process, and the accumulation of starch and storage proteins is regulated starting at the mRNA level . The RNA-Seq technique provided a powerful tool on … WebApr 26, 2024 · Intriguingly, we have found that the sum of grain filling rates around 15 and 38 days after flowering largely determines grain yield, and have further developed a novel in situ approach quantifying grain filling rates and grain yield precisely with the measurements of ear respiratory rates (r>0.93).

Synergistic interaction between ABA and IAA due to moderate

WebConventional thinking to explain the poor grain-filling is the consequence of carbon limitation. Recent studies, however, have shown that carbohydrate supply should not be … WebAbstract Poor grain filling of inferior spikelets is becoming a severe problem in some super rice varieties with large panicles. Moderate soil drying (MD) after pollination has been proven to be a practical strategy to promote grain filling. However, the molecular mechanisms underlying this phenomenon remain largely unexplored. inbound e outbound tradução

WebDec 1, 2024 · At the individual panicle level, reduction in grain filling was evidenced by decreased fully filled spikelet percentage, fertilized spikelet weight, and grain plumpness, and increased partially filled spikelet percentage in the bottom part of the panicle as total N rates increased. WebMay 30, 2024 · Rice quality is directly determined by grain filling of rice spikelets, which is largely regulated by changing environments, like temperature, light and water. Adverse reproductive stage environments remarkably decrease rice quality by affecting starch biosynthesis process. WebNov 2, 2005 · These results indicate that increased grain filling rate is mainly attributable to enhanced sink activity through regulation of key enzymes involved in sucrose-to-starch … in and out in wa
