摘要
植物受到生物或非生物胁迫时,病程相关蛋白(pathogenesis-related proteins,PRs)PR-5家族(又称类甜蛋白,thaumatin-like proteins,TLPs)在植物组织内迅速表达并积累,从而快速提高植物抗性。研究发现许多植物的TLPs具有抗真菌活性,而且转TLPs基因的植物能够抑制病害发展进程。介绍了TLPs基因的分布起源和进化特征、结构特征、生理功能;分析了TLPs基因在不同植物中的差异表达特征、TLPs的抗真菌机制以及TLPs基因在植物抗病遗传改良中的应用;提出了植物TLPs未来研究的主要问题以及TLPs基因在林木病理学和林木抗病遗传育种中的应用前景。
Thaumatin-like proteins（TLPs） are a pathogenesis-related protein associated with many biotic or abiotic stresses that can be expressed in plants,animals,and even fungi.This study reviewed phylogenetic origin,three-dimensional structure,physiological function,as well as expression and evolution patterns of plant TLPs.The prospect of trans-TLP genes for antifungal genetic engineering of plants was also discussed.Finally,selected future research issues and perspectives related to plant TLPs were mentioned.
