植物物种在叶子形态上表现出显着的差异。我们分离出了一种隐性突变基因，称为小心形叶 1 (scl1)，它会导致黄瓜叶子大小和形状的改变。与野生型叶片相比，scl1突变体的表皮铺装细胞数量较少。单核苷酸多态性与该叶表型相关，其发生在假定的核苷二磷酸磷酸酶中。对野生型和 scl1 突变体叶子的 RNA-seq 分析表明，SCL1 调节可能不涉及已知的激素途径。我们的工作确定了 SCL1 的候选基因，该基因可能在叶子发育中发挥作用。
Plant species exhibit substantial variation in leaf morphology. We isolated a recessive mutant gene termed small and cordate leaf 1 (scl1) that causes alteration in both leaf size and shape of cucumber. Compared to wild type leaves, the scl1 mutant had fewer numbers of epidermal pavement cells. A single nucleotide polymorphism was associated with this leaf phenotype, which occurred in a putative nucleoside bisphosphate phosphatase. RNA-seq analysis of the wild type and scl1 mutant leaves suggested that SCL1 regulation may not involve known hormonal pathways. Our work identified a candidate gene for SCL1 that may play a role in leaf development.
