Anthracnose caused by Colletotrichum is one of the most severe diseases that can afflict Camellia sinensis. However, research on the diversity and geographical distribution of Colletotrichum in China remain limited. In this study, 106 Colletotrichum isolates were collected from diseased leaves of Ca. sinensis cultivated in the 15 main tea production provinces in China. Multi-locus phylogenetic ...

Avocado (Persea americana) is one of the most important crops in Mexico as it is the main producer, consumer, and exporter of avocado fruit in the world. However, successful avocado commercialization is often reduced by large postharvest losses due to Colletotrichum sp., the causal agent of anthracnose. Chitosan is known to have a direct antifungal effect and acts also as an elicitor capable of...

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...

Paclitaxel (taxol) has long been used as a potent anticancer agent for the treatment of many cancers. Ever since the fungal species Taxomyces andreanae was first shown to produce taxol in 1993, many endophytic fungal species have been recognized as taxol accumulators. In this study, we analyzed the taxol-producing capacity of different Colletotrichum spp. to determine the distribution of a taxo...

Colletotrichum gloeosporioides is an important pathogen for a great number of economically important crops. During the necrotrophic phase of infection by Colletotrichum spp, the degradative enzymes of plant cell walls, such as pectate lyase, clearly increase. A gene pelB that expresses a pectate lyase was identified in isolates of C. gloeosporioides in avocado pathogens. Various molecular studi...

Phylogenetic analysis of Rhizopus strains based on the D1/D2 region of LSU rDNA sequences yielded a phylogram with four well-supported clades. The R. microsporus clade concurs with classification obtained by traditional methods. The R. oryzae group was found to include species of the genus Amylomyces. The traditional R. stolonifer group was divided into two well-supported clades in the phylogra...

Infection structures were observed at the penetration sites on the leaves of cucumber plants inoculated with Colletotrichum orbiculare using a fluorescence microscope. The cucumber plants were previously drenched with suspension of bacterial strains Pseudomonas putida or Micrococcus luteus. The plants pre-inoculated with both bacterial strains were resistant against anthracnose after inoculatio...

CASE REPORT A 23 years old male with an unremarkable past medical history suffered an injury with a branch of a lemon tree in the right eye two days prior to presentation. The slit-lamp examination showed a central corneal erosion with a white tree-shaped stromal infiltrate and Tyndall +/++ in anterior chamber. Cultivation of corneal scraping was positive for Colletotrichum spp. The patient res...

Anthracnose is a general term for sunken lesions and blights on stems, leaves and fruits which causes economic damage to agricultural products. This study, conducted to identify Colletotrichum species associated with anthracnose symptoms on some plants in Khuzestan province (Iran) using morphological and molecular methods. During 2016–17, 40 leaf and fruit samples showing anthracnose symptoms (...
