适度卷叶有助于提高光合效率和籽粒产量。受体样细胞质激酶（Receptor-like cytoplasmic kinase, RLCKs）在植物生长发育过程中起着重要作用。然而，它们在水稻叶片形态发生中的作用却知之甚少。在这里，我们报道了flrrk1（叶片滚动受体样细胞质激酶1）的分离和表征，这是一个参与叶片滚动调控的RLCK基因。LRRK1主要定位于质膜，在体内被磷酸化。水稻中flrrk1的过表达减少了近轴细胞层的球状细胞的大小，从而导致叶片正向卷曲。然而，在rrk1突变体中缺乏flrrk1并没有导致可检测的视觉表型。LRRK1可上调球状细胞发育中负调控因子的表达，下调正调控因子的表达。这些结果表明LRRK1是参与球状细胞发育的负调节因子。在合理的密植条件下，过表达lrrk1的植株穗数显著高于野生型植株。综上所述，这些发现表明LRRK1在调节叶片卷曲中发挥重要作用，是培育具有理想植株结构和提高籽粒产量的候选基因。
Moderate leaf rolling is useful in improving photosynthetic efficiency and grain yields. Receptor-like cytoplasmic kinases (RLCKs) play important roles in plant growth and development. However, little is known about their functions in rice leaf morphogenesis. Here, we report the isolation and characterization ofLRRK1(leaf rolling receptor-like cytoplasmic kinase 1), an RLCK gene involved in the regulation of leaf rolling. LRRK1 was mainly localized at the plasma membrane and was phosphorylated in vivo. Overexpression ofLRRK1in rice reduced the size of bulliform cells at the adaxial cell layers, which caused in turn adaxially rolled leaves. However, deficiency ofLRRK1in thelrrk1mutant did not result in a detectable visual phenotype. LRRK1 could upregulate the expression of negative regulators but downregulate the expression of positive regulators of bulliform cell development. These results indicate that LRRK1 is a negative regulator involved in the bulliform cell development. Furthermore, the panicle numbers inLRRK1-overexpressing plants increased significantly compared with the wild-type plants under a rational close planting condition. Taken together, these findings suggest that LRRK1 plays an important role in regulating leaf rolling and is a promising candidate gene for breeding rice with ideal plant architecture and improved grain yield.
