Background The YABBY gene family is a family of small zinc finger transcription factors associated with plant morphogenesis, growth, and development. In particular, it is closely related to the development of polarity in the lateral organs of plants. Despite being studied extensively in many plant species, there is little information on genome-wide characterization of this gene family in Moso bamboo. Methods In the present study, we identified 16 PeYABBY genes, which were unequally distributed on 11 chromosomes, through genome-wide analysis of high-quality genome sequences of M oso bamboo by bioinformatics tools and biotechnological tools. Gene expression under hormone stress conditions was verified by quantitative real-time PCR (qRT-PCR) experiments. Results Based on peptide sequences and similarity of exon-intron structures, we classified the PeYABBY genes into four subfamilies. Analysis of putative cis-acting elements in promoters of these genes revealed that PeYABBYs contained a large number of hormone-responsive and stress-responsive elements. Expression analysis showed that they were expressed at a high level in Moso bamboo panicles, rhizomes, and leaves. Expression patterns of putative PeYABBY genes in different organs and hormone-treated were analyzed using RNA-seq data, results showed that some PeYABBY genes were responsive to gibberellin (GA) and abscisic acid (ABA), indicating that they may play an important role in plant hormone responses. Gene Ontology (GO) analyses of YABBY proteins indicated that they may be involved in many developmental processes, particularly high level of enrichment seen in plant leaf development. In summary, our results provide a comprehensive genome-wide study of the YABBY gene family in bamboos, which could be useful for further detailed studies of the function and evolution of the YABBY genes, and to provide a fundamental basis for the study of YABBY in Gramineae for resistance to stress and hormonal stress.

Moso Bamboo (Phyllostachys edulis (Carrière) J. Houz) 中 YABBY 基因家族的全基因组鉴定和分析

背景 YABBY 基因家族是一个与植物形态发生、生长和发育相关的小锌指转录因子家族。特别是与植物侧生器官极性的发育密切相关。尽管在许多植物物种中进行了广泛的研究，但关于毛竹中该基因家族的全基因组特征的信息很少。方法在本研究中，我们通过生物信息学工具和生物技术工具对毛竹高质量基因组序列进行全基因组分析，鉴定出16个PeYABBY基因，这些基因在11条染色体上分布不均。通过定量实时 PCR (qRT-PCR) 实验验证激素应激条件下的基因表达。结果 基于肽序列和外显子-内含子结构的相似性，我们将 PeYABBY 基因分为四个亚家族。对这些基因启动子中推定的顺式作用元件的分析表明，PeYABBYs含有大量的激素反应和应激反应元件。表达分析表明，它们在毛竹的圆锥花序、根茎和叶片中均有高表达。使用 RNA-seq 数据分析推定的 PeYABBY 基因在不同器官和激素处理的表达模式，结果显示部分 PeYABBY 基因对赤霉素（GA）和脱落酸（ABA）有反应，表明它们可能在植物激素反应。YABBY 蛋白的基因本体论 (GO) 分析表明它们可能参与许多发育过程，特别是在植物叶片发育中看到的高水平富集。总之，
