GATA proteins are transcription factors of zinc finger proteins, which play an important role in plant growth development and abiotic stress. However, there have been no identification or systematic studies of the gene family in eggplant. In this study, 28 genes were identified in the genome database of eggplant, which could be divided into four subgroups. Plant development, hormones, and stress-related -acting elements were identified in promoter regions of the gene family. RT-qPCR indicated that 4 genes displayed upregulated expressions during fruit developmental stage, whereas 2 genes were down-regulated expression patterns. It was also demonstrated that genes may be involved in light signals to regulate fruit anthocyanin biosynthesis. Furthermore, the expression patterns of genes under ABA, GA and MeJA treatments showed that the s were involved in the process of fruit ripening. Notably, and were highly correlated with the expression of anthocyanin biosynthesis genes, light-responsive genes, and genes that function in multiple hormone signaling pathways and the proteins they encoded were localized in the nucleus. All these results showed genes likely play a major role in regulating fruit anthocyanin biosynthesis by integrating the light, ABA, GA and MeJA signaling pathways and provided references for further research on fruit quality in eggplant.
GATA蛋白是锌指蛋白转录因子，在植物生长发育和非生物胁迫中发挥重要作用。然而，茄子中尚未对该基因家族进行鉴定或系统研究。本研究在茄子基因组数据库中鉴定出28个基因，可分为四个亚组。在该基因家族的启动子区域鉴定出与植物发育、激素和胁迫相关的作用元件。RT-qPCR表明，4个基因在果实发育阶段表达上调，而2个基因呈下调表达模式。还证明这些基因可能参与光信号以调节果实花青素生物合成。此外，这些基因在ABA、GA和MeJA处理下的表达模式表明它们参与果实成熟过程。值得注意的是，某些基因与花青素生物合成基因、光响应基因以及在多种激素信号通路中起作用的基因的表达高度相关，并且它们编码的蛋白质定位于细胞核。所有这些结果表明，这些基因可能通过整合光、ABA、GA和MeJA信号通路在调节果实花青素生物合成中起主要作用，并为茄子果实品质的进一步研究提供了参考。
