Aims: Crown gall, a phytobacteriosis characterized by the formation of tumours on plant roots was observed in recently planted vineyards of the Meknes region (Morocco). The objective of this research was to analyse the diversity of pathogenic agrobacteria isolated from grapevine in Morocco.
Methods And Results: Eighty-two isolates from 11 affected vineyards were characterized by recA sequencing and were found to belong to Agrobacterium tumefaciens genomospecies G1, G4 or G7, Rhizobium rhizogenes, and to Allorhizobium vitis.
Article Synopsis
- Allorhizobium (Agrobacterium) vitis is a pathogenic bacterium that causes crown gall disease in grapevines, negatively impacting growth and production globally.
- Essential oils from Origanum compactum and Thymus vulgaris displayed strong antibacterial effects against A. vitis, with minimal inhibitory concentrations (MIC) of 0.156 mg/mL and 0.312 mg/mL, respectively.
- A combined application of these essential oils not only exhibited a synergistic antibacterial effect but also significantly reduced gall symptoms and tumor size in tomato and grapevine plants when tested in vivo.
