摘要:

发根农杆菌(Agrobacterium rhizogenes)是一种革兰氏阴性土壤杆菌,通过其携带的Ri质粒中的rol基因可以诱导植物形成毛状根。由于毛状根培养具有成本低、生长速度快、遗传稳定等优点,发根农杆菌介导的植物遗传转化已成为基因功能研究的理想转化体系。本文中系统总结了发根农杆菌介导的毛状根诱导及遗传转化方法,包括非组织培养法和组织培养法,并深入讨论了不同条件下影响转化效率的因素。在非组织培养条件下植物种类、侵染材料、侵染方式、发根农杆菌类型、侵染液浓度以及侵染后处理条件等显著影响转化效率,而在组织培养条件下,共培养基类型、化学诱导剂则为关键调控因素。发根农杆菌介导的植物基因编辑效率同样受各方面因素的影响,包括菌株的选择、转化类型、基因编辑工具的设计等。文章中还综述了发根农杆菌介导的CRISPR/Cas9系统在植物基因功能研究和分子育种中的具体应用。

Abstract:

Agrobacterium rhizogenes is a Gram-negative soil bacterium that induces the formation of hairy roots in plants through the rol genes located on its Ri plasmid. Due to the advantages of hairy root cultures,such as low cost,rapid growth rate,and genetic stability,A.rhizogenes-mediated plant genetic transformation has become an ideal system for gene function research. This article systematically summarizes the methods for hairy root induction and genetic transformation mediated by A. rhizogenes,including non-tissue culture and tissue culture approaches. It further delves into the factors influencing transformation efficiency under different conditions:Under non-tissue culture conditions,plant species,explant type,infection method,A. rhizogenes strain,bacterial concentration,and post-infection treatment conditions significantly impact transformation efficiency. Conversely,the type of co-culture medium and chemical inducers are key regulatory factors under tissue culture conditions. Various aspects,including strain selection,transformation methods,and genome editing tool design,similarly influence the efficiency of A. rhizogenes-mediated plant genome editing. The review also summarizes the specific applications of A. rhizogenes-mediated CRISPR/Cas9 systems in plant gene functional studies and molecular breeding.

Key words: Agrobacterium rhizogenes, genetic transformation, CRISPR/Cas9, genome editing
