摘要:

丁烯基多杀菌素(butenyl-spinosyn)是一种由须糖多孢菌(Saccharopolyspora pogona)产生的杀虫剂,兼具生物农药的安全性和化学农药的速效性。当前,野生型须糖多孢菌合成丁烯基多杀菌素效率低,达不到工业生产要求,获得高产菌株是亟待解决的问题。目前关于丁烯基多杀菌素的相关研究较少,由刺糖多孢菌(Saccharopolyspora spinosa)产生的多杀菌素是丁烯基多杀菌素的结构类似物,具有相似的生物合成途径,本文介绍了两者的基本特性,借鉴多杀菌素的研究经验总结了丁烯基多杀菌素高产菌株已有及可用的选育和改造策略,包括传统的理化诱变方法以及代谢流调控、途径基因调控、转录调控、异源表达等更加精准的基因工程方法,以期为后续丁烯基多杀菌素的深入研究提供思路。

Abstract:

Butenyl-spinosyn is an insecticide produced by Saccharopolyspora pogona, which has both the safety of biological pesticides and the quick-acting properties of chemical pesticides. However, the low synthesis efficiency of butenyl-spinosyn by wild-type strains cannot meet the need of industrial production, obtaining high-yield strains is an urgent problem. At present, there are few related studies on butenyl-spinosyn. The spinosyn produced by Saccharopolyspora spinosa has a similar structural and biosynthetic pathway. This article describes the basic characteristics of them, draws on the research experience of spinosyn, summarizes the available strategies for breeding and modifying high-yield butenyl-spinosyn strains, including mutagenesis methods and precise genetic engineering methods such as metabolic flux regulation, pathway genes regulation, transcriptional regulation, heterologous expression, which may provide ideas for further research of butenyl-spinosyn.
