The genome of Phaeomoniella chlamydospora was sequenced by the Department of Viticulture and Enology at University of California Davis (http://cantulab.github.com). The genome sequence and gene predictions were downloaded from NCBI on Sept 24, 2015. Please note that this copy of the genome is not maintained by NCBI and is therefore not automatically updated. JGI tools were used to add functional annotation to the gene models.

The ascomycete P. chlamydospora (W. Gams, Crous, M.J. Wingf. & Mugnai) is part of a group of pathogens that cause the Esca disease complex in grapevines. External symptoms of Esca diseased plants include a typical “tiger-stripes” pattern on chlorotic leaves, delayed bud break, and formation of necrotic spots or “measles” on berries. Internal symptoms include brown to black spots or streaks in xylem vessels and white necrosis characterized by a dried spongy consistency due to the colonization by secondary Esca pathogens. The sequenced isolate (UCR-PC4) was recovered from diseased grapevine wood (V. vinifera cv. Flame) in Coachella Valley, Riverside Co., California, in November 2011.
