Etiology 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...
متن کاملMeristem culture for the elimination of the strawberry crown rot pathogen Phytophthora cactorum
Two methods to induce a symptomless infection of crown rot (Phytophthora cactorum) in stolons of three strawberry (Fragaria×ananassa) cultivars were evaluated. Spraying a 10−4 ml zoospore suspension was the most effective method, producing a mean infection rate of 12%. Meristem cultures were subsequently established from all of the inoculated stolons and tested eight weeks later for the presenc...
متن کاملGenetic and Pathogenic Analyses of Colletotrichum gloeosporioides Isolates from Strawberry and Noncultivated Hosts.
ABSTRACT Colletotrichum crown rot of strawberry in Florida is caused primarily by Colletotrichum gloeosporioides. To determine potential inoculum sources, isolates of Colletotrichum spp. from strawberry and various noncultivated plants growing in the areas adjacent to strawberry fields were collected from different sites. Species-specific internal transcribed spacer primers for C. gloeosporioid...
متن کاملRelative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile
G. Guzmán, B.A. Latorre, R. Torres, and W.F. Wilcox. 2007. Relative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile. Cien. Inv. Agr. 34(1):31-40. Crown gall (Agrobacterium tumefaciens) and Phytophthora root and crown rot (PRCR), caused by P. cryptogea, are two major limiting factors affecting peach (Prunus persica) production in Chile. At present, N...
