Supercoiling of an excised genomic island represses effector gene expression to prevent activation of host resistance (2018)
Journal Article
Neale, H., Jackson, R., Preston, G., & Arnold, D. (2018). Supercoiling of an excised genomic island represses effector gene expression to prevent activation of host resistance. Molecular Microbiology, 110(3), 444-454. https://doi.org/10.1111/mmi.14111

© 2018 The Authors Molecular Microbiology Published by John Wiley & Sons Ltd. The plant pathogen Pseudomonas syringae pv. phaseolicola, which causes halo blight disease of beans, contains a 106kb genomic island PPHGI-1. PPHGI-1 carries a gene, avrP...

Hydrogen sulfide causes excision of a genomic island in Pseudomonas syringae pv. phaseolicola (2017)
Journal Article
Neale, H., Deshappriya, N., Arnold, D. L., Wood, M. E., Whiteman, M., & Hancock, J. T. (2017). Hydrogen sulfide causes excision of a genomic island in Pseudomonas syringae pv. phaseolicola. European Journal of Plant Pathology, 149(4), 911-921. https://doi.org/10.1007/s10658-017-1240-7

© 2017, The Author(s). Hydrogen sulfide (H2S) is known to be an important signalling molecule in both animals and plants, despite its toxic nature. In plants it has been seen to control stomatal apertures, so altering the ability of bacteria to invad...

A low frequency persistent reservoir of a genomic island in a pathogen population ensures island survival and improves pathogen fitness in a susceptible host (2016)
Journal Article
Neale, H., Laister, R., Payne, J., Preston, G., Jackson, R., & Arnold, D. L. (2016). A low frequency persistent reservoir of a genomic island in a pathogen population ensures island survival and improves pathogen fitness in a susceptible host. Environmental Microbiology, 18(11), 4144-4152. https://doi.org/10.1111/1462-2920.13482

The co-evolution of bacterial plant pathogens and their hosts is a complex and dynamic process. Host resistance imposes stress on invading pathogens that can lead to changes in the bacterial genome enabling the pathogen to escape host resistance. We...

© 2015 Manoharan et al. The bacterial plant pathogen Pseudomonas syringae pv. phaseolicola (Pph) colonises the surface of common bean plants before moving into the interior of plant tissue, via wounds and stomata. In the intercellular spaces the path...
