Strawberry Anthracnose: Histopathology of Colletotrichum acutatum and C. fragariae.
ABSTRACT Ontogeny of the invasion process by Colletotrichum acutatum and C. fragariae was studied on petioles and stolons of the strawberry cultivar Chandler using light and electron microscopy. The invasion of host tissue by each fungal species was similar; however, each invasion event occurred more rapidly with C. fragariae than with C. acutatum. Following cuticular penetration via an appress...
متن کاملEtiology and Population Genetics of Colletotrichum spp. Causing Crown and Fruit Rot of Strawberry.
ABSTRACT Isolates of Colletotrichum spp. from diseased strawberry fruit and crowns were evaluated to determine their genetic diversity and the etiology of the diseases. Isolates were identified to species using polymerase chain reaction primers for a ribosomal internal transcribed spacer region and their pathogenicity was evaluated in bioassays. Isolates were scored for variation at 40 putative...
متن کاملResistance of Strawberry Cultivars to Crown Rot Caused by Colletotrichum gloeosporioides Isolates from Florida Is Nonspecific
Colletotrichum crown rot of strawberry (Fragaria × ananassa Duchesne) can be caused by any of three fungi, Colletotrichum gloeosporioides (teleomorph Glomerella cingulata), C. fragariae, or C. acutatum (17,27). The closely related species C. fragariae and C. gloeosporioides produce a reddish-brown necrosis of crown tissue following infection that causes plants to wilt and collapse (27). Under g...
