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.
植物结构是作物产量的一个重要决定因素。最近的研究表明，SPL 家族基因调控着水稻植株的结构。SPL 通常抑制分蘖，但在最佳表达水平下促进穗分枝，从而增加籽粒数。精细调控 SPL 基因的表达可能为作物改良提供有用的策略。
