在水稻的驯化和改良过程中，增加粮食产量以满足人类的需求是首要目标。水稻籽粒产量是由多基因决定的数量性状，但其增产的分子基础尚不清楚。在这里，我们表明，谷物1（NOG 1），编码烯酰辅酶A水合酶/异构酶，增加水稻的籽粒产量，通过提高每穗粒数，而不会对每株穗数或粒重产生负面影响。NOG 1基因的导入使缺失NOG 1的水稻品种中花17的产量提高了25.8%，而在含有NOG 1基因的特青中，NOG 1基因的过量表达使产量进一步提高了19.5%。NOG 1基因在增加穗粒数方面起着显著作用，但不影响抽穗期和结实率。我们的研究结果表明，NOG 1可以用来增加水稻产量。水稻产量是由多基因控制的数量性状。在此，作者发现编码脂肪酸β-氧化途径中的烯酰辅酶A水合酶/异构酶的NOG 1可以通过增加每穗粒数来增加籽粒产量，而不影响其他产量构成性状。
During rice domestication and improvement, increasing grain yield to meet human needs was the primary objective. Rice grain yield is a quantitative trait determined by multiple genes, but the molecular basis for increased grain yield is still unclear. Here, we show that NUMBER OF GRAINS 1 (NOG1), which encodes an enoyl-CoA hydratase/isomerase, increases the grain yield of rice by enhancing grain number per panicle without a negative effect on the number of panicles per plant or grain weight. NOG1 can significantly increase the grain yield of commercial high-yield varieties: introduction of NOG1 increases the grain yield by 25.8% in the NOG1-deficient rice cultivar Zhonghua 17, and overexpression of NOG1 can further increase the grain yield by 19.5% in the NOG1-containing variety Teqing. Interestingly, NOG1 plays a prominent role in increasing grain number, but does not change heading date or seed-setting rate. Our findings suggest that NOG1 could be used to increase rice production. Rice grain yield is a quantitative trait determined by multiple genes. Here, the authors find NOG1, which encodes an enoyl-CoA hydratase/isomerase in fatty acid β-oxidation pathway, can increase grain yield by enhancing grain number per panicle without affecting the other yield component traits.
