Taxonomy and multi-locus phylogeny of cylindrocarpon-like species associated with diseased roots of grapevine and other fruit and nut crops in California.

ABSTRACT: Black foot disease is a common and destructive root disease of grapevine caused by a multitude of cylindrocarpon-like fungi in many viticultural areas of the world. This study identified 12 cylindrocarpon-like fungal species across five genera associated with black foot disease of grapevine and other diverse root diseases of fruit and nut crops in the Central Valley Region of California. Morphological observations paired with multi-locus sequence typing of four loci, internal transcribed spacer region of nuclear rDNA ITS1-5.8S-ITS2 (ITS), beta-tubulin (TUB2), translation elongation factor 1-alpha (TEF1), and histone (HIS), revealed 10 previously described species; Campylocarpon fasciculare, Dactylonectria alcacerensis, D. ecuadoriensis, D. macrodidyma, D. novozelandica, D. torresensis, D.
