植物向陆地的过渡需要几种调节适应机制。对这些机制知之甚少，但它们无疑涉及转录因子（TF）家族的进化。乙烯不敏感3（EIN 3）/类EIN 3（EIL 3-Like）转录因子（TF）是乙烯信号转导途径的核心组分，通过调控许多基因的转录，在植物发育和环境响应的几乎各个方面发挥重要作用。然而，EIN 3/EIL TF的进化历史，这是目前在广泛的链霉菌，仍然不清楚。为了探讨EIN 3/EIL转录因子的进化和功能，我们对这些转录因子进行了系统发育分析，并研究了它们的基因和蛋白质结构以及序列特征。我们的研究结果表明，EIN 3/EIL TF家族已经存在于链藻的祖先。系统发育分析将EIN 3/EIL转录因子分为三组（A组-C组）。基因和蛋白质结构的分析表明，这些TF的大部分结构特征已经在古代谱系中形成。进一步的研究表明，所有群体都经历了与植物全基因组复制有关的几次复制事件，产生了多个功能多样的基因拷贝。因此，随着植物在陆地栖息地定居并进化出关键性状，EIN 3/EIL TF家族通过多次重复事件广泛扩展，这可能促进了其基本的新功能和亚功能化，以帮助植物适应陆地生活。我们的研究结果阐明了EIN 3/EIL TF家族在链霉菌中的功能进化。
The transition of plants to land required several regulatory adaptive mechanisms. Little is known about these mechanisms, but they no doubt involved the evolution of transcription factor (TF) families. ETHYLENE-INSENSITIVE 3 (EIN3)/EIN3-LIKE (EIL) transcription factors (TFs) are core components of the ethylene signaling pathway that play important roles in almost every aspect of plant development and environmental responses by regulating the transcription of numerous genes. However, the evolutionary history of EIN3/EIL TFs, which are present in a wide range of streptophytes, is still not clear. Here, to explore the evolution and functions of EIN3/EIL TFs, we performed phylogenetic analysis of these TFs and investigated their gene and protein structures as well as sequence features. Our results suggest that the EIN3/EIL TF family was already was already present in the ancestor of streptophyte algae. Phylogenetic analysis divided the EIN3/EIL TFs into three groups (Group A–C). Analysis of gene and protein structure revealed that most of the structural features of these TFs had already formed in ancient lineages. Further investigation suggested that all groups have undergone several duplication events related to whole-genome duplications in plants, generating multiple, functionally diverse gene copies. Therefore, as plants colonized terrestrial habitats and evolved key traits, the EIN3/EIL TF family expanded broadly via multiple duplication events, which could have promoted their fundamental neo- and sub-functionalization to help plants adapt to terrestrial life. Our findings shed light on the functional evolution of the EIN3/EIL TF family in the streptophytes.
