YABBY家族基因在叶、花和果实的发育中起着重要作用。本研究的目的是整合所有YABBY基因，并分析基因表达与番茄果实形状的相关性。对24个已测序物种的基因组扫描结果表明，除无核植物外，YABBY基因在有花植物中均表现正常且稳定。番茄中的9个YABBY基因的计算和实验特征。基于整个蛋白质或YABBY结构域构建了进化树，并观察到5个不同的进化枝，如在其他被子植物中所描述的。通过比较果实形状和/或大小差异较大的番茄中YABBY基因的表达模式，表明在果实发育过程中，YABBY基因既有负功能也有正功能。这些信息有助于我们更深入地了解YABBY基因的进化过程，并为番茄产量和形态育种提供参考。
YABBY family genes play important roles in the development of leaf, flower, and fruit. The purpose of this research was to integrate all the YABBY genes and analyze the correlation between gene expression and fruit shape in tomato. Scanning of 24 genomes of sequenced species demonstrated that YABBY genes were very normal and stable in flowering plants except the seedless plants. Nine YABBY genes in tomato were computationally and experimentally characterized. The phylogeny was constructed based on whole proteins or the YABBY domain, and five distinct clades were observed as described in other angiosperms. A comparison of the expression patterns in tomatoes with large differences in fruit shape and/or size suggested that during the fruit development, YABBY genes had both negative and positive functions. The obtained information could provide a deeper understanding of the evolution of YABBY genes and can also be useful for tomato yield and shape breeding.
