Growth-regulating factors (GRFs) are plant-specific transcription factors that perform important functions in plant growth and development. Herein, we identified and characterised 24 genes in peanut (). family genes were divided into six classes with OLQ and WRC domains. Transcriptome expression profile showed that more genes, such as 5a gene, were at higher expression during pod development in than cultivated species, especially at the pod rapid-expansion stage. 5a and 5b genes expressed at higher levels in pods than roots, leaves and stems tissues, existing in the difference between and H8107. Exogenous GA3 application can activate 5a and 5b genes and H8107 line showed more positive response than species. These results imply that these two genes may be active during the peanut pod development.
生长调节因子（GRFs）是植物特异性转录因子，在植物生长发育中发挥重要功能。本研究中，我们从花生中鉴定和分析了 24 个 家族基因。这些家族基因被分为六个类群，具有 OLQ 和 WRC 结构域。转录组表达谱显示，在荚果发育过程中，与栽培种相比，更多的 基因，如 5a 基因，在 中表达更高，尤其是在荚果快速扩张阶段。5a 和 5b 基因在荚果中的表达水平高于根、叶和茎组织，存在于 与 H8107 之间的差异。外源 GA3 处理可以激活 5a 和 5b 基因，而 H8107 系比 种表现出更积极的响应。这些结果表明，这两个 基因可能在花生荚果发育过程中发挥作用。
