Abstract
Strawberry anthracnose fruit rot and root necrosis, caused by Colletotrichum acutatum, are primary limiting factors in fruit production fields in the U.S. Recent research focusing on the phenotypic and genetic diversity of this species has shed light on the complexity of C. acutatum species. In this study, we performed multilocus sequence analysis of four genetic loci to characterize 217 C. acutatum isolates collected over a 23-yr period from symptomatic plant tissues of strawberry from six different states. The results revealed two Colletotrichum species with 97.7% of the isolate collection (212/217) belonging to a dominant clonal linage, regardless of the isolation source. No correlation between species groups and geographical origins of the isolates was observed, either. Further sequence comparison between historical and contemporary isolates showed the same populations being widely spread throughout the strawberry nurseries and production fields in the U.S. and Canada. Afterward, a subset of 12 isolates representing different quinone-outside inhibitor fungicide resistance profiles from root or fruit tissue of strawberry was selected for comparison of pathogenicity on strawberry. Of these isolates tested, isolates of different resistance groups or different isolation sources exhibited a similar degree of aggressiveness and caused indistinguishable symptoms on strawberry crowns and fruit, though a significant difference among individual isolates was observed in detached fruit assays (P = 0.0123). Separate pathogenicity tests using isolates of the two species revealed C. nymphaeae being more aggressive than C. fioriniae in infecting strawberry roots and crowns. Therefore, given the occurrence and pathogenicity of C. nymphaeae, this species is likely the sole culprit responsible for strawberry anthracnose in the U.S.
