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
