Characterization of Colletotrichum acutatum causing anthracnose of anemone (Anemone coronaria L.)

Article Abstract:

Researchers used vegetative-compatibility to group 72 isolates of Colletotrichum acutatum into three groups even though they were genotypically homogeneous using molecular assays. One VCG included most of the organisms that caused two epidemics of anthracnose of anemone in Israel whereas another VCG included most of the organisms that caused a third epidemic.

Molecular and phenotypic analyses reveal association of diverse Colletotrichum acutatum groups and a low level of C. gloeosporioides with olive anthracnose

Article Abstract:

Anthranose is an important disease causing major yield losses and poor oil quality in olives. A study was conducted to determine the diversity and distribution pattern of Colletotrichum spp. populations prevalent in olives and their relatedness to anthracnose pathogens in other hosts, assess their pathogenic variability and host preference, and develop diagnostic tools.

Characterization of Colletotrichum gloeosporioides isolates from avocado and almond fruits with molecular and pathogenicity tests

Article Abstract:

A study was conducted to determine the genetic diversity and host specificity between and among various populations of 120 isolates of Colletotrichum gloeosporiodes from avocado and almond fruits. Molecular markers and a pathogenicity assay were used. Avocado isolates produced lesions on avocado and almond fruit while almond isolates infected both avocados and almonds at a lower rate in artificial inoculations.
