Interspecies Hybrids

Plant essential oils of six aromatic herb species and interspecies hybrids of the family Lamiaceae – chocolate mint (Mentha piperita × ‘Chocolate’), pineapple mint (Mentha suaveolens ‘Variegata’), apple mint (Mentha × rotundifolia), spearmint (Mentha spicata), orange mint (Mentha × piperita ‘Granada’) and strawberry mint (Mentha × villosa ‘Strawberry’) – were investigated for antimicrobial effects against plant pathogenic bacteria: Agrobacterium tumefaciens, Pseudomonas syringae pv. syringae and Xanthomonas arboricola pv. corylina. The screening was carried out in vitro on agar plates filled with the target organism. All essential oils screened exhibited a higher level of antibacterial activity against A. tumefaciens and X. arboricola pv. corylina than streptomycin used as a standard in all tests. The antimicrobial effect of streptomycin and five mint oils was at the same level for P. syringae pv. syringae. There were no significant differences in the influence of the chocolate mint oil on the growth inhibition of all bacteria tested. Plant essential oils from pineapple mint, apple mint, spearmint and strawberry mint showed the weakest antimicrobial activity against P. syringae pv. syringae and the strongest towards A. tumefaciens and X. arboricola pv. corylina. The essential oils from strawberry mint, pineapple mint, spearmint and apple mint had the strongest effect on A. tumefaciens, and the lowest inhibitory activity was exhibited by the chocolate mint and orange mint essential oils. X. arboricola pv. corylina was the most sensitive to the strawberry mint, pineapple mint and spearmint oils. The chocolate mint oil showed the greatest activity against P. syringae pv. syringae.

Plant Pathogenic Bacteria

Essential oils are volatile substances from plants and many of them have antimicrobial activity. For that reason, they have become known as a useful alternative to chemical preservatives and pesticides. In this study, we tested essential oils of four aromatic plants. Cinnamon (Cinnamomum zeylanicum), thyme (Thymus vulgaris), oregano (Origanum vulgare) and clove (Syzygium aromaticum) essential oils were investigated for their composition and antimicrobial effect against plant pathogenic bacteria (Pectobacterium spp. and Pseudomonas spp.). Both are commonly associated with diseased fruit trees in orchards and gardens. The chemical composition of the tested essential oils was identified by gas chromatography coupled with mass spectrometry. The cinnamon essential oil was most effective form tested oil. The experimental results indicated that the wild strains of tested bacteria are more resistant to essential oils than commonly used laboratory strains. In conclusion, certain essential oils could be used for the control of postharvest bacterial pathogens. The findings of the present study suggest that the essential oils have a potential to be used as antimicrobial agents.

Abstract Background Gene transfer agents (GTAs) are phage-like mediators of gene transfer in bacterial species. Typically, strains of a bacteria species which have GTA shows more recombination than strains without GTAs. GTA-mediated gene transfer activity has been shown for few bacteria, with Rhodobacter capsulatus being the prototypical GTA. GTA have not been previously studied in plant pathogenic bacteria. A recent study inferring recombination in strains of the bacterial spot xanthomonads identified a Nigerian lineage which showed unusual recombination background. We initially set out to understand genomic drivers of recombination in this genome by focusing on mobile genetic elements. Results We identified a unique cluster which was present in the Nigerian strain but absent in other sequenced strains of bacterial spot xanthomonads. The protein sequence of a gene within this cluster contained the GTA_TIM domain that is present in bacteria with GTA. We identified GTA clusters in other Xanthomonas species as well as species of Agrobacterium and Pantoea. Recombination analyses showed that generally, strains of Xanthomonas with GTA have more inferred recombination events than strains without GTA, which could lead to genome divergence.Conclusion This study identified GTA clusters in species of the plant pathogen genera Xanthomonas, Agrobacterium and Pantoea which we have named XpGTA, AgGTA and PaGTA respectively. Our recombination analyses suggest that Xanthomonas strains with GTA generally have more inferred recombination events than strains without GTA. The study is important in understanding the drivers of evolution of bacterial plant pathogens.
