Abstract

Myelocytomatosis (MYC) transcription factors (TFs) belong to the basic helix-loop-helix (bHLH) family in plants and play a central role in governing a wide range of physiological processes. These processes encompass plant growth, development, adaptation to biotic and abiotic stresses, as well as secondary metabolism. In recent decades, significant strides have been made in comprehending the multifaceted regulatory functions of MYCs. This advancement has been achieved through the cloning of MYCs and the characterization of plants with MYC deficiencies or overexpression, employing comprehensive genome-wide 'omics' and protein-protein interaction technologies. MYCs act as pivotal components in integrating signals from various phytohormones' transcriptional regulators to orchestrate genome-wide transcriptional reprogramming. In this review, we have compiled current research on the role of MYCs as molecular switches that modulate signal transduction pathways mediated by phytohormones and phytochromes. This comprehensive overview allows us to address lingering questions regarding the interplay of signals in response to environmental cues and developmental shift. It also sheds light on the potential implications for enhancing plant resistance to diverse biotic and abiotic stresses through genetic improvements achieved by plant breeding and synthetic biology efforts.

植物 MYC 转录因子功能研究的进展。
髓细胞瘤(MYC)转录因子(TFs)属于植物中的基本螺旋-环-螺旋(bHLH)家族,在调控一系列生理过程中发挥着核心作用。这些过程包括植物的生长、发育、对生物和非生物胁迫的适应以及次生代谢。近几十年来,人们在理解 MYCs 的多方面调控功能方面取得了长足进步。这一进展是通过克隆 MYCs 以及利用全面的全基因组 "组学 "和蛋白质-蛋白质相互作用技术分析 MYC 缺失或过表达植物的特征实现的。MYCs 是整合各种植物激素转录调控因子信号的关键元件,可协调全基因组转录重编程。在这篇综述中,我们汇编了目前有关 MYCs 作为分子开关调节由植物激素和植物色素介导的信号转导通路的作用的研究。这一全面综述使我们能够解决有关信号在响应环境线索和发育转变时的相互作用的未决问题。它还揭示了通过植物育种和合成生物学努力实现的遗传改良来增强植物对各种生物和非生物胁迫的抵抗力的潜在意义。

期刊介绍: Theoretical and Applied Genetics publishes original research and review articles in all key areas of modern plant genetics, plant genomics and plant biotechnology. All work needs to have a clear genetic component and significant impact on plant breeding. Theoretical considerations are only accepted in combination with new experimental data and/or if they indicate a relevant application in plant genetics or breeding. Emphasizing the practical, the journal focuses on research into leading crop plants and articles presenting innovative approaches.
