Research Project: Genomic Approaches for Improving Plant Health in Nursery Production

Location: Horticultural Crops Research

Project Number: 2072-22000-041-21-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 15, 2018
End Date: Sep 14, 2019

Objective:
Characterization of plant pathogen diversity and communities in commercial nursery production systems.

Approach:
This project will identify genetic diversity of Phytophthora pathogens including P. ramorum and other important Phytophthora species. Briefly, we will use population genomic approaches to profile genetic diversity in populations of select Phytophthora species. Variation among isolates within species will be assessed using genotyping methods including genotyping by sequencing (GBS) as well as plant pathology assays to determine phenotypic diversity. Metabarcoding approaches will be used to determine community diversity in Phytophthora species in nurseries and other environments.
