In plants, the () gene family is unique and responds to ubiquitous stress and hormones, playing important regulatory roles in the growth and development of plants, as well as in the resistance mechanisms to biotic and abiotic stress. In this study, a total of 23 s were characterized in using a genome-wide approach, and their phylogenetic relationships, gene structures, conserved motifs, chromosomal locations, gene duplications, and promoter regions were systematically analyzed. Expression profile analysis derived from transcriptome data showed that s are expressed at higher levels in the flowers or fruit than in the leaves, vines, and roots. The expression of s also showed habitat- and environmental-stress-regulated patterns in analyzed by transcriptome and quantitative reverse transcription PCR (qRT-PCR). The heterologous induced expression of some s in yeast enhanced the tolerance to HO, and some s showed elevated heat tolerance and heavy metal (HM) Cd/Cu tolerance. These findings will provide an important foundation to elucidate the biological functions of genes, especially their role in the ecological adaptation of specific plant species to tropical islands and reefs in .
在植物中，（）基因家族是独特的，它响应普遍存在的应激和激素，在植物的生长和发育以及生物和非生物胁迫的抗性机制中发挥重要的调节作用。在这项研究中，采用全基因组方法在 中鉴定了 23 个 ，并系统分析了它们的系统发育关系、基因结构、保守基序、染色体定位、基因复制和启动子区。来自转录组数据的表达谱分析表明，与叶片、藤和根相比，在花或果实中表达水平更高。通过转录组和定量逆转录 PCR（qRT-PCR）分析， 中的 也表现出对生境和环境胁迫的表达调控模式。一些 在酵母中的异源诱导表达增强了对 HO 的耐受性，一些 表现出提高的耐热性和重金属（HM）Cd/Cu 耐受性。这些发现将为阐明 基因的生物学功能提供重要基础，特别是它们在特定植物物种对 和珊瑚礁等热带岛屿的生态适应中的作用。
