The Multiprotein Bridging Factor 1 (MBF1) proteins are transcription co-factors whose molecular function is to form a bridge between transcription factors and the basal machinery of transcription. MBF1s are present in most archaea and all eukaryotes, and numerous reports show that they are involved in developmental processes and in stress responses. In this review we summarize almost three decades of research on the plant MBF1 family, which has mainly focused on their role in abiotic stress responses, in particular the heat stress response. However, despite the amount of information available, there are still many questions that remain about how plant MBF1 genes, transcripts, and proteins respond to stress, and how they in turn modulate stress response transcriptional pathways.

植物 MBF1 蛋白家族：压力和转录之间的桥梁。

多蛋白桥接因子 1 (MBF1) 蛋白是转录辅助因子，其分子功能是在转录因子和转录的基础机制之间形成一座桥梁。MBF1 存在于大多数古细菌和所有真核生物中，许多报告表明它们参与发育过程和应激反应。在这篇综述中，我们总结了近三年来对植物 MBF1 家族的研究，主要集中在它们在非生物胁迫反应中的作用，特别是热胁迫反应。然而，尽管可用的信息量很大，但关于植物 MBF1 基因、转录物和蛋白质如何应对压力，以及它们如何反过来调节压力反应转录途径，仍然存在许多问题。
