Venturia comparative genomics consortium
The Venturia comparative genomics consortium is made up of laboratories from Plant & Food Research, Auckland, New Zealand; La Trobe University, Melbourne, Australia; ZTH, Zurich, Switzerland and INRA, Angers, France.
The goal of the consortium is to share whole genome sequence data and associated expression analyses to facilitate the identification of effector proteins involved in causing disease and the molecular basis for specificity of different Venturia species and formae speciales.
The genus Venturia is a member of the Dothideomycetes. Many Venturia species are plant pathogens, the most important is V. inaequalis which infects members of the Maloideae. It is the most significant pathogen of apple worldwide. Its subcuticular pathogenic lifestyle is unique and the genes controlling this and nutrient acquisition are unknown. Control is currently mediated through a managed regime of fungicide treatments but the continual evolution of resistance to these fungicides is making the disease harder to control. Many single dominant resistance (R) genes are present in the extensive Malus germplasm but individually all have been broken. Research into the effector complement of Venturia is required to identify the combination of R-genes that will give durable resistance, the ultimate goal for breeders and growers.
Four isolates of Venturia inaequalis (including one isolated from Loquat)have been sequenced in addition to the pear pathogen Venturia pirina. If you would like to access the Venturia genomes contact Dr Joanna Bowen. Consult the User's Guide for information on using the wiki software.
