The genome sequence and gene predictions of Neofusicoccum parvum were not determined by the JGI, but were downloaded from NCBI and have been published (Barbara Blanco-Ulate et al,, 2013). Please note that this copy of the genome is not maintained by the author and is therefore not automatically updated.

The genome of Neofusicoccum parvum was sequenced by the Department of Viticulture and Enology at University of California Davis (http://cantulab.github.com). 

The ascomycete Neofusicoccum parvum, (Pennycook & Samuels) Crous, Slippers, and Phillips (teleomorph Botryosphaeria parva), a member of the Botryosphaeriaceae family, is a vascular pathogen that causes severe decline and dieback symptoms in grapevines worldwide.

N. parvum penetrates grapevines through pruning and grafting wounds and colonizes the host tissues, causing shoot dieback, cane bleaching, bud necrosis, and graft failure. Wedge-shaped necrosis in the vascular tissues of spurs, cordons, and trunks are typical symptoms of N. parvum infections

The sequenced strain (UCR-NP2) was isolated from the margin of a grapevine (Vitis vinifera cv. “Zinfandel”) wood canker collected in Riverside County (California) in 2011.
