is often described as a generalist pathogen, with isolates causing disease in a range of plant species. It is the causative agent of two diseases in the cultivated strawberry, crown rot (CR; causing whole plant collapse) and leather rot (LR; affecting the fruit). In the cultivated apple, causes girdling bark rots on the scion (collar rot) and rootstock (crown rot), as well as necrosis of the fine root system (root rot) and fruit rots.

Identification and Expression of Pathogenicity Genes in f. sp. .

Genetic and phenotypic associations between root architecture, arbuscular mycorrhizal fungi colonisation and low phosphate tolerance in strawberry (Fragaria × ananassa).

Background: Phosphate is an essential plant macronutrient required to achieve maximum crop yield. Roots are able to uptake soil phosphate from the immediate root area, thus creating a nutrient depletion zone. Many plants are able to exploit phosphate from beyond this root nutrient depletion zone through symbiotic association with Arbuscular Mycorrhizal Fungi (AMF).

Draft Genome Sequence of the Strawberry Anthracnose Pathogen .

is a causal agent of strawberry anthracnose and a major economic pathogen of horticultural and ornamental crops worldwide. Here, we present an annotated draft genome sequence for a isolate previously used for transcriptomic analysis. The assembly totals 58.

Genomics Evolutionary History and Diagnostics of the Species Group Including Apple and Asian Pear Pathotypes.

The section ( species group) represents a diverse group of saprotroph, human allergens, and plant pathogens. taxonomy has benefited from recent phylogenetic revision but the basis of differentiation between major phylogenetic clades within the group is not yet understood. Furthermore, genomic resources have been limited for the study of host-specific pathotypes.

Basal Rot of : Understanding Pathogenicity in f. sp. .

is a globally distributed soilborne fungal pathogen causing root rots, bulb rots, crown rots and vascular wilts on a range of horticultural plants. Pathogenic isolates are highly host specific and are classified as . is an important ornamental crop and both the quality and yield of flowers and bulbs can be severely affected by a basal rot caused by f.

Identifying Resistance in Strawberry Through Disease Screening of Multiple Populations and Image Based Phenotyping.

is a highly detrimental pathogen of soil cultivated strawberry (). Breeding of Verticillium wilt resistance into commercially viable strawberry cultivars can help mitigate the impact of the disease. In this study we describe novel sources of resistance identified in multiple strawberry populations, creating a wealth of data for breeders to exploit.

CRISPR/Cas9-mediated mutagenesis of phytoene desaturase in diploid and octoploid strawberry.

Background: Gene editing using CRISPR/Cas9 is a simple and powerful tool for elucidating genetic controls and for crop improvement and its use has been reported in a growing number of important food crops, including recently . In order to inform application of the technology in e targeted the visible endogenous marker gene (phytoene desaturase) in diploid ssp. 'Hawaii 4' and octoploid  ×  'Calypso'.

Vegetative compatibility groups partition variation in the virulence of Verticillium dahliae on strawberry.

Verticillium dahliae infection of strawberry (Fragaria x ananassa) is a major cause of disease-induced wilting in soil-grown strawberries across the world.
