KNOTTEDI 样同源框 (KNOXI) 基因调节茎尖分生组织 (SAM) 的叶子发育，并可能调节叶子形状。我们检查了各种维管植物 SAM 中的 KNOXI 表达，发现 KNOXI 表达与复杂的叶原基相关。然而，复杂的原基可能成熟为简单的叶子。因此，并非所有简单的叶子都发育相似，并且最终的叶子形态可能不足以预测同源性。
KNOTTEDI-like homeobox (KNOXI) genes regulate development of the leaf from the shoot apical meristem (SAM) and may regulate leaf form. We examined KNOXI expression in SAMs of various vascular plants and found that KNOXI expression correlated with complex leaf primordia. However, complex primordia may mature into simple leaves. Therefore, not all simple leaves develop similarly, and final leaf morphology may not be an adequate predictor of homology.
