Growth of fruits which form an important part of human diet has been jeopardized by the many fungal diseases that are present today. This study was conceived to isolate the most common fungal pathogens in passion fruits. Fungi were isolated using potato dextrose agar in addition to characterization using morphological, cultural, and biochemical means. Extraction of essential oils from rosemary ...

The fungal diversity associated with leaves, flowers and fruits of olive (Olea europaea) was investigated in different phenological stages (May, June, October and December) using an implemented metabarcoding approach. It consisted of the 454 pyrosequencing of the fungal ITS2 region and the subsequent phylogenetic analysis of relevant genera along with validated reference sequences. Most sequenc...

In tropical fruit crops, anthracnose is mainly caused by species belonging to the fungal genus, Colletotrichum. These phytopathogens can infect several parts of crops; however, infection during postharvest or ripening stages responsible for major economic losses. Due formation black dark brown sunken lesions on surface, reduces quality and marketability. Among most common crops susceptible are ...

Species of Colletotrichum cause diseases on a wide range of hosts, frequently infecting plants in the Agavaceae (monocotyledons: Liliales). Three species of Colletotrichum restricted to the Agavaceae were detected through morphological studies of specimens and molecular sequence analyses of the LSU of the nu-rDNA and the ITS region of the nu-rDNA from cultures. Colletotrichum agaves on Agave is...

Pepper (Capsicum spp.) is an important vegetable crop worldwide with high economic and nutritional value. The Capsicum genus comprises more than 30 species, of which C. annuum, chinense, baccatum, frutescens, pubescens are the five domesticated ones. Anthracnose fruit rot, caused by Colletotrichum spp., one most destructive fungal diseases pepper. In this review, we compiled up-to-date informat...

Common bean (Phaseolus vulgaris L.) is an important legume with high nutritional value. In Nicaragua, certified healthy seeds of local bean varieties are not available, and seedborne fungi have gained little attention. Here, were surveyed seedborne pathogenic fungi in an important local bean cultivar, 'INTA Rojo'. Beans grown in the four main production areas in Nicaragua (Boaco, Carazo, Estelí...

Euonymus spp. (L.) are some of the most important ornamental plants. Fungal plant pathogens of ornamental plants are the most important factors causing damage. In this research two pathogenic fungal species were isolated from naturally infected Euonymus species and identified. In order to isolation of fungi from disease tissues, the obtained samples were cultured on potato dextrose agar medium....

ABSTRACT Ninety-five isolates of Colletotrichum including 81 isolates of C. acutatum (62 from strawberry) and 14 isolates of C. gloeosporioides (13 from strawberry) were characterized by various molecular methods and pathogenicity tests. Results based on random amplified polymorphic DNA (RAPD) polymorphism and internal transcribed spacer (ITS) 2 sequence data provided clear genetic evidence of ...
