Growth-regulating factor (GRF) is a multi-gene family that plays an important role in plant growth and development and is widely present in plants. Currently, gene members have been reported in many plants, but the gene family has not been found in sweet potato. In this study, ten genes were identified in sweet potato (), twelve and twelve were identified in its two diploid relatives () and (), which were unevenly distributed on nine different chromosomes. Subcellular localization analysis showed that genes of sweet potato, , and were all located in the nucleus. The expression analysis showed that the expression of was diverse in different sweet potato parts, and most of the genes were upregulated and even had the highest expression in the vigorous growth buds. These findings provide molecular characterization of sweet potato and its two diploid relatives, the families, further supporting functional characterization.
生长调节因子（GRF）是一个多基因家族，在植物的生长发育中起着重要作用，广泛存在于植物中。目前，在许多植物中已经报道了基因成员，但在甘薯中尚未发现基因家族。本研究在甘薯中鉴定出 10 个基因（），在其两个二倍体近亲（）和（）中分别鉴定出 12 个和 12 个，它们不均匀地分布在 9 条不同的染色体上。亚细胞定位分析表明，甘薯的、和基因均位于细胞核中。表达分析表明，在不同的甘薯部位中，的表达是多样化的，大多数基因上调，甚至在生长旺盛的芽中表达最高。这些发现为甘薯及其两个二倍体近亲提供了分子特征，进一步支持了功能特征。
