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 کاملCharacterization of Infection and Colonization of Strawberry Crowns by Colletotrichum acutatum
Strawberry anthracnose, caused by Colletotrichum acutatum J.H. Simmonds, is one of the most important diseases of this crop in Huelva (southwestern Spain). Lesions can occur on all parts of the plant but anthracnose crown rot is specially severe leading to wilt and death of plants. In this work, the infection and colonization process of C. acutatum on strawberry plants was studied. ‘Camarosa’ s...
متن کاملInheritance of Resistance to Colletotrichum acutatum Simmonds on Runners of Garden Strawberry and its Backcrosses
Two half diallel mating designs were conducted to study the inheritance of resistance to Colletotrichum acutatum Simmonds on runners of strawberry. The main design included six genotypes representing a range of responses to the pathogen: ‘Chandler’ (very susceptible); FL 87-210 (tolerant); MS/US 541 (very resistant); NC 92-01 (Fragaria chiloensis Duch.) (resistant); NCH 87-10 (tolerant-suscepti...
متن کاملPathogenic and Nonpathogenic Lifestyles in Colletotrichum acutatum from Strawberry and Other Plants.
ABSTRACT Anthracnose is one of the major fungal diseases of strawberry occurring worldwide. In Israel, the disease is caused primarily by the species Colletotrichum acutatum. The pathogen causes black spot on fruit, root necrosis, and crown rot resulting in mortality of transplants in the field. The host range and specificity of C. acutatum from strawberry was examined on pepper, eggplant, toma...
متن کاملThe Colletotrichum acutatum species complex
UNLABELLED Colletotrichum acutatum is known as an important anthracnose pathogen of a wide range of host plants worldwide. Numerous studies have reported subgroups within the C. acutatum species complex. Multilocus molecular phylogenetic analysis (ITS, ACT, TUB2, CHS-1, GAPDH, HIS3) of 331 strains previously identified as C. acutatum and other related taxa, including strains from numerous hosts...
