First Report of Grapevine Cankers Caused by Lasiodiplodia crassispora and Neofusicoccum mediterraneum in California

First Report of Dieback Caused by Lasiodiplodia theobromae in Strawberry Plants in Korea

Dieback in strawberry (Seolhyang cultivar) was first observed during the nursery season (June to September) in the Nonsan area of Korea in the years 2012 and 2013. Initial disease symptoms included dieback on runners, as well as black rot on roots, followed by wilting and eventually blackened, necrotic discoloration in the crowns of daughter plants. A fungus isolated from the diseased roots, ru...

Draft Genome Sequence of Neofusicoccum parvum Isolate UCR-NP2, a Fungal Vascular Pathogen Associated with Grapevine Cankers

Neofusicoccum parvum, a member of the Botryosphaeriaceae family, is a vascular pathogen that causes severe decline and dieback symptoms in grapevines worldwide. The draft genome of the grapevine isolate N. parvum UCR-NP2 provides a first glimpse into the complex set of putative virulence factors that this pathogen may use to rapidly colonize plants.

Grapevine Production in California

By the time of the Gold Rush, the vineyard area had reached a few hundred acres and grapes were sold to high prices in Los Angeles and San Francisco [3, 10] . As a consequence of the lucrative prices, many vineyards were planted and the area reached 56,000 acres in 1880 [10] . However, due to Pierce’s Disease in the 1880s, areas in the south became unsuitable to vines and the industry was force...

Genes Expressed in Grapevine Leaves Reveal Latent Wood Infection by the Fungal Pathogen Neofusicoccum parvum

Some pathogenic species of the Botryosphaeriaceae have a latent phase, colonizing woody tissues while perennial hosts show no apparent symptoms until conditions for disease development become favorable. Detection of these pathogens is often limited to the later pathogenic phase. The latent phase is poorly characterized, despite the need for non-destructive detection tools and effective quaranti...
