Review of Research Progress of Sophora moorcroftiana in Xizang
摘要
Abstract
Sophora moorcroftiana is a unique legume dwarf shrub on the Qinghai-Xizang Plateau.Its drought resistance,barren resistance,and windbreak and sand fixation characteristics make it a key species for ecological restoration in the Yarlung Zangbo River Basin.It is also rich in quinolizidine alkaloids such as matrine and oxymatrine,and has medicinal development potential such as anti-tumor and anti-parasite.Based on the main line of'environmental adaptation-gene regulation-secondary metabolism-resource utilization',this paper systematically reviewed the bioecological characteristics,secondary metabolite synthesis and function,efficient cultivation technology,genetic diversity and genomic resources,and drought stress response mechanism of Sophora moorcroftiana.The focus is on:(1)the chemical diversity of alkaloids and their potential coupling relationship with drought adaptation;(2)the differentiation law and gene flow pattern of population genetic structure along the altitude gradient;(3)optimized path of hard seed breaking,in vitro propagation and stress-resistant cultivation techniques;(4)the molecular basis of the DREB transcription factor family and sucrose metabolism gene expansion in drought resistance.At present,there are still some bottlenecks in the research,such as unclear key enzymes in the alkaloid biosynthesis pathway,unclear mechanisms of synergistic improvement of drought resistance and quality traits,and immature large-scale breeding technology systems.In future,it is necessary to integrate multi-omics technology to analyze the'stress-defense'coupling mechanism,construct a molecular design breeding system,and establish a high-value utilization model of ecological-medicinal coupling,so as to provide theoretical and technical support for vegetation restoration and Tibetan medicine resource development in plateau arid valleys.关键词
