Description
Xanthomonas arboricola pv. pruni (Xap) causes bacterial spot and
canker on a wide range of Prunus spp. (e.g., apricot, peach, plum,
al-mond, cherry). Outbreaks on stone fruits can result in severe
economic losses to fruit quality and yield, branch/tree dieback,
and orchard devastation. Xap is endemic in the USA, NZ and is a
quarantine regulated pathogen in Europe and elsewhere. Control
options for this pathogen are actually quite limited and there is
an increasing invasion risk with 1) climate change and 2) wide host
range of this pathogen.
Despite the regulatory and economic significance of Xap,
surprisingly little is known about its genetics. Genetic studies
have for the most part been limited to biodiversity analysis.
We apply genomics in order to identify this invasive pathogen
Achilles’ heel (e.g., virulence or fitness determinants) that can
be exploited for development of improved control compounds and
phytosanitary strategies. We have sequenced the complete genome of
a genotypic-representative Xap strain from Europe, use our
assembled genome as a template for assembly of sequences of other
pathovars and are pursuing comparative genomics with other
Xanthomonas species that have been sequenced.
