Genetic diversity of Actinidia spp. shapes the oomycete pattern associated with Kiwifruit Vine Decline Syndrome (KVDS)

| description | Abstract Kiwifruit Vine Decline Syndrome (KVDS) is an important soil-borne disease for the Italian kiwifruit industry, causing €300,000 in economic losses in 2020 alone. So far, the organisms recognized as involved in the aetiology of KVDS mainly belong to the Oomycota. As no effective management strategies exist, a promising approach to overcoming KVDS is the use of resistant species as rootstocks or for inclusion in breeding programs. Several Actinidia genotypes showing different level of resistance to KVDS were grown in disease-promoting soils. A metabarcoding approach was set up to identify KVDS-associated oomycetes and investigate whether the main species involved may vary according to plant genotype. Our results clearly showed significant differences between the genotypes in terms of oomycetes present in both plant rhizosphere and endosphere, which were strongly correlated with the symptoms displayed. We found out that the resistance of Actinidia macrosperma to KVDS is related to its ability to shape the pathobiome, particularly as far as the endosphere is concerned. In our conditions, Phytophthora sp. was predominantly found in sensitive genotypes, whilst Globisporangium intermedium was mainly detected in asymptomatic plants, suggesting that the latter species could compete with the recruitment of Phytophthora sp. in plants with different levels of resistance, consequently, explaining the onset of symptoms and the resistance condition. |
