Selection for Pathogenicity to Strawberry in Populations of Colletotrichum gloeosporioides from Native Plants.
ABSTRACT Colletotrichum gloeosporioides causes a serious crown rot of strawberry and some isolates from native plants are pathogenic to strawberry. C. gloeosporioides from lesions on wild grape and oak were sampled at two sites adjacent to commercial strawberry fields in Florida and two distant sites. Random amplified polymorphic DNA (RAPD) marker data and restriction enzyme digests of amplifie...
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 کاملCOMPARISON OF PATHOGENICITY OF Fusarium equiseti AND Colletotrichum graminicola ON Echinochloa spp
Echinochloa spp. are the most important weeds in rice fields. In this research Fusarium equiseti and Colletotrichum graminicola were isolated from these weeds and then their pathogenicity effects were compared on these weeds and five rice cultivars in a completely random design with three replications in greenhouse conditions. Fungi were inoculated on weeds and rice cultivars using a spore susp...
متن کاملIsolation of Chlamydia spp. from Ewes and Does in Iran
Enzootic ovine abortion is caused by Chlamydia abortus and may result in abortion among small ruminants during the last 2-3 weeks of pregnancy. Enzootic abortion is diagnosed by isolation of the agent or detection of its nucleic acid in the products of abortion or vaginal excretions of freshly aborted females. Isolation of chlamydial agents in cell culture is the gold standard, so in the presen...
متن کاملStrawberry 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...
