YABBY基因（蟹爪、LAMENTOUS FLOWER、YABBY2和YABBY3）在侧部器官（如叶）的远轴侧表达，并且参与真双子叶植物拟南芥（Arabidopsis thaliana）远轴组织身份的建立。在这里，我们报告的表达模式的YABBY2同源物在侧器官的Amborella spicipoda，一个早期发散被子植物。我们发现该同源物在心皮和叶的近轴组织中表达，而在A.这表明YABBY2表达的不同模式在被子植物中进化。
YABBY genes (CRABS CLAW, LAMENTOUS FLOWER, YABBY2, and YABBY3) are expressed on the abaxial side of lateral organs, such as leaves, and are involved in the establishment of abaxial tissue identity in the eudicot Arabidopsis thaliana. Here we report the expression patterns of a YABBY2 homologue in the lateral organs of Amborella trichopoda, an early‐diverging angiosperm. We found that the homologue is expressed in the adaxial tissues of the carpel and leaf, in contrast to abaxial expression in A. thaliana, which indicates that different patterns of YABBY2 expression evolved within the angiosperms.
