Researchers revealed the genome sequence of a devastating tree pathogen. The disease threatens the Scandinavian broadleaf forests and this new knowledge can help stop it!
The new genome resource can be used in future population genomic studies for identification of haplotypes and alleles, and in identifying which effectors may function in infection of woody host plants.
The genome sequence presented provides a resource that can underpin further investigation into the mechanisms of disease caused by P. plurivora, a prevalent but little researched pathogen of important tree species. Our genome sequence of P. plurivora is consistent with the genome architecture of other sequenced Phytophthora species, and we found evidence for elevated ploidy, as can occur in Phytophthora species.
Causes huge economic loss
Plant pathogens belonging to the genus Phytophthora cause disastrous diseases and are responsible for multi-billion dollar losses in agriculture and forestry. Several Phytophthoras such as P. plurivora, P. alni, P. cambivoraand P. cactorum are now endemic problems in Scandinavian forests.
Despite causing diseases of different tree species in forest ecosystems, little is known about the mechanisms by which Phytophthoras invade and colonise trees, or the molecular interactions that take place between tree infecting Phytophthoras and host trees. Significant investment has been targeted to develop solutions for Phytophthora crop diseases, most notably for P. infestans and P. sojae.
Limited knowledge
By contrast, there has been divestment in tree biology, particularly the genomic and molecular skills. Consequently, we have limited knowledge about the infection biology of endemic and recently discovered pathogenic Phytophthoras that are an increasing threat to trees in Sweden and worldwide, and the tree resistance mechanisms that may control them. The overarching objective of our research is to investigate mechanisms of host-pathogen interactions and to identify ways to control diseases caused by tree infecting Phytophthoras.
Here we present a draft genome sequence of P. plurivora, originally isolated from diseased European beech (Fagus sylvatica) in Malmö, Sweden. Compared to other sequenced Phytophthora species, the P. plurivora genome assembly is relatively compact, spanning 41 Mb.

On February 6 last year, the seminar “Digitalization of agriculture – when and how is the big revolution?” was arranged by NKJ together with Partnership Alnarp, SLU. NKJ was also co-organizer of ICT Agris Conference 24 November 2017 in Copenhagen: “ICT-AGRI Conference on ICT and Robotics for a Sustainable Agriculture”. Digitalization is and has been a priority issue, and the emphasis in the latest NKJ call was digitalization. There is a lot going on in this important issue, and NKJ wants to contribute to the development.
April 17th SNS and NKJ gathered people with expertise in the agricultural, forest and digital sectors to learn, discuss and take a step forward in digitalization of the bioeconomy. Experts say we are on the edge to a structural shift paramount to the industrial revolution – digitalization is around the corner.
