Grapevine crown gall (GCG) is a major disease caused by the Allorhizobium vitis that causes significant losses in grape industry. In this study, strain of Agrobacterium tumefaciens (Ag-8) from soil was found to have effect on grapevine gall. The present study conducted investigate potential impact AraC family transcription factor ata (Agrobacterium AraC) biocontrol capacity Ag-8 and elucidate mechanisms its action. To end, an deletion mutant (Δata) constructed. It biofilm, motility, colonization were significantly lower than those wild Ag-8. By analyzing Δata transcriptome data, we focused our attention ABC transporter protein araH, RT-qPCR showed it down-regulated strain. follow-up candidate gene araH (ΔaraH) biofilm formation, ability wild-type Therefore, may be implicated as pivotal target modulating capability This supports developing strategies targeting ata-regulated enhance sustainable management
