GRAS transcription factors play multifunctional roles in plant growth, development, and resistance to various biotic and abiotic stresses. The structural and functional features of GRAS TFs have been unveiled in the last two decades. A typical GRAS protein contained a C-terminal GRAS domain with a highly variable N-terminal region. Studies on these TFs increase in numbers and are reported to be involved in various important developmental processes such as flowering, root formation, and stress responses. The GRAS TFs and hormone signaling crosstalk can be implicated in plant development and to stress responses. There are relatively few reports about GRAS TFs roles in plants, and no related reviews have been published. In this review, we summarized the features of GRAS TFs, their targets, and the roles these GRAS TFs playing in plant development and multiple stresses.
GRAS 转录因子在植物的生长、发育和对各种生物及非生物胁迫的抗性中发挥着多种功能。在过去的二十年中，GRAS TF 的结构和功能特征已经被揭示。一个典型的 GRAS 蛋白包含一个具有高度可变的 N 端区域的 C 端 GRAS 结构域。对这些 TF 的研究数量不断增加，并被报道参与各种重要的发育过程，如开花、根形成和应激反应。GRAS TF 和激素信号转导的相互作用可能与植物的发育和应激反应有关。关于 GRAS TF 在植物中的作用的报道相对较少，也没有相关的综述发表。在这篇综述中，我们总结了 GRAS TF 的特征、它们的靶标以及这些 GRAS TF 在植物发育和多种胁迫中的作用。
