Plant architecture is an important determinant of crop yield. Recent studies showed that SPL family genes regulate the architecture of rice plants. SPLs inhibit tillering in general, but promote panicle branching at optimal expression levels to increase grain number. Fine-tuning the expression of SPL genes may provide useful strategies for crop improvement.

通过微调SPL基因表达提高水稻产量

植物结构是作物产量的重要决定因素。最近的研究表明，SPL家族基因调节水稻植株的结构。SPL通常抑制分till，但以最佳表达水平促进穗分枝以增加籽粒数。微调SPL基因的表达可能为作物改良提供有用的策略。
