TL;DR: The finding of pathogenic, wood-infecting Diaporthe spp.

TL;DR: The absence of multilocus linkage disequilibrium and the high proportion of unique genotypes suggest that spore dispersal is an important part of the ecology and establishment of A. mellea in this ornamental landscape.

TL;DR: A new infection assay is tested, in which grape rootstocks growing in tissue culture medium are inoculated, and compared to rootstocks previously characterized from the existing infection assay as tolerant (Freedom) or susceptible (3309C); findings of higher percent root colonization than Freedom at all harvests suggests that the quantitative methods of the new assay give similar results to the qualitative method of theexisting infection assay.

TL;DR: Eutypa dieback of grapevine is caused by Eutypa lata in production areas with Mediterranean climates in California, Australasia, Europe, and South Africa and in the colder, eastern North American vineyards where cultivars adapted from native Vitis spp.

TL;DR: This genetic transformation system for the genus Armillaria, in combination with new markers to track chromosomal and cytoplasmic inheritance in A. mellea, will advance research aimed at characterizing the significance of somatic recombination in the ecology of this important fungus.
