Moso bamboo (Phyllostachys edulis) is well known for its rapid shoot growth. Auxin exerts pleiotropic effects on plant growth. The small auxin-up RNA (SAUR) genes are early auxin-responsive genes involved in plant growth. In total, 38 SAUR genes were identified in P. edulis (PheSAUR). A comprehensive overview of the PheSAUR gene family is presented, including the gene structures, phylogeny, and subcellular location predictions. A transcriptome analysis indicated that 37 (except PheSAUR18) of the PheSAUR genes were expressed during shoot growth process and that the PheSAUR genes were differentially expressed. Furthermore, quantitative real-time PCR analysis indicated that all of the PheSAUR genes could be induced in different tissues of seedlings and that 37 (except PheSAUR41) of the PheSAUR genes were up-regulated after indole-3-acetic acid (IAA) treatment. These results reveal a comprehensive overview of the PheSAUR gene family and may pave the way for deciphering their functions during bamboo development.
毛竹（Phyllostachys edulis）以其笋的快速生长而闻名。生长素对植物生长具有多效性作用。小生长素上调RNA（SAUR）基因是参与植物生长的早期生长素响应基因。在毛竹中总共鉴定出38个SAUR基因（PheSAUR）。本文对PheSAUR基因家族进行了全面概述，包括基因结构、系统发育和亚细胞定位预测。转录组分析表明，37个PheSAUR基因（除PheSAUR18外）在笋生长过程中表达，且PheSAUR基因存在差异表达。此外，定量实时PCR分析表明，所有PheSAUR基因均可在幼苗的不同组织中被诱导，并且37个PheSAUR基因（除PheSAUR41外）在吲哚-3-乙酸（IAA）处理后上调。这些结果揭示了PheSAUR基因家族的全面概况，并可能为解读它们在竹子发育过程中的功能铺平道路。
