Abstract

MYB44 played key roles in plant responses to abiotic and biotic stress and important roles in plant metabolism and development. At present, the function of MYB44 has not been systemically summarized in plants. In this review, we systemically summarized the structure and function of MYB44 in plants, such as how MYB44 interplays in phytohormone signaling pathways; how MYB44 regulates abiotic and biotic stress, which includes drought tolerance, salt tolerance, cold tolerance, responding to phosphate and nitrogen starvation, and disease resistance; and how MYB44 regulates plant metabolism, which contains MYB44 regulates fruit malate accumulation, starch biosynthesis, sucrose accumulation, flavonoid accumulation, anthocyanin biosynthesis, chlorophyll degradation, and leaf senescence; it also regulates plant development, which includes root growth and development and somatic embryogenesis in plants. Moreover, we constructed the regulatory networks of the MYB44 protein's responses to biotic and abiotic stress and their regulation of plant metabolism and development. Furthermore, we give some suggestions on how to use MYB44 as a positive and negative regulator to create new breeds in the future.

MYB44在调节植物对非生物和生物胁迫、代谢和发育的反应中起关键作用

MYB44在植物对非生物和生物胁迫的响应中起关键作用，在植物代谢和发育中起重要作用。目前，对MYB44在植物中的功能还没有系统的总结。本文对MYB44在植物中的结构和功能进行了系统的综述，包括MYB44在植物激素信号通路中的相互作用;MYB44如何调节非生物和生物胁迫，包括耐旱性、耐盐性、耐寒性、对磷酸盐和氮饥饿的响应以及抗病性;MYB44如何调控植物代谢，其中MYB44调控果实苹果酸积累、淀粉生物合成、蔗糖积累、类黄酮积累、花青素生物合成、叶绿素降解和叶片衰老;它还调节植物的发育，包括植物根的生长发育和体细胞胚胎发生。此外，我们还构建了MYB44蛋白对生物和非生物胁迫的响应及其对植物代谢和发育的调控网络。最后，对今后如何利用MYB44作为正调控因子和负调控因子来培育新品种提出了建议。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
