摘要
苦荞
Fagopyrum tataricum
被誉为“五谷之王”，是集营养、保健于一体的药食同源植物，其富含大量黄酮类化合物芦丁等，氨基酸组成均衡，具有降血糖、降血脂、降血压及抗氧化、抗衰老、抗癌防癌、改善血管微循环等多重功效。转录因子是调控植物基因表达的重要因子，在植物生长发育中发挥着重要的作用。MYB家族转录因子是指含有MYB结构域的一类转录因子，是植物最大的转录因子家族之一，根据其结构不同主要分为1R-MYB，R2R3-MYB，3R-MYB，4R-MYB四个家族，在植物生长发育与类黄酮次生代谢调控中发挥着重要的作用。该研究对苦荞中已报道的MYB家族转录因子进行总结和系统聚类分析，梳理了他们所属的亚家族以及相互关系，为进一步挖掘和克隆苦荞MYB家族转录因子提供参考。在此基础上，该文进一步综述了以上MYB家族转录因子在苦荞类黄酮生物合成途径、植物激素以及逆境等非生物胁迫过程中的调控作用，并对苦荞MYB家族转录因子的功能挖掘与调控机制研究进行展望，为苦荞MYB家族转录因子的功能研究和苦荞优质品种选育提供科学参考。
Abstract
Known as "the king of the five grains"
tartary buckwheat (
Fagopyrum tataricum
) is a medicinal and edible plant with both nutritional and healthcare functions. It contains rich flavonoids
such as rutin
with balanced amino acid composition and multiple effects
like blood fat-lowering
blood giucose-lowering
blood pressure-lowering
anti-oxidation
anti-aging
anti-cancer
anti-cancer
and microcirculation-improving. Transcription factors play important roles in plant growth and development by regulating gene expressions. MYB family is one of the largest transcription factor families in plant
contains the MYB domain
and can be divided into four subfamilies: 1R-MYB
R2R3-MYB
3R-MYB
4R-MYB. This family plays various roles in plant growth
plant development and flavonoid biosynthesis of secondary metabolism. In this study
the reported MYB transcription factors in
F
.
tataricum
were summarized and systemically clustered
and their interrelationships were defined to provide references for further exploring and cloning MYB transcription factors in
F
.
tataricum
. In addition
this study reviewed their regulatory functions of MYB transcription factors in flavonoid biosynthesis pathway
plant hormones pathways and other abiotic stress pathways
and made a conclusion and advances about the future research in
F
.
tataricum
. Therefore
this study will provide valuable scientific references for the functional studies of MYB family transcription factors in
F
.
tataricum
and its molecular breeding for high-quality varieties.
