AVOCADO FRUIT RESPONSES TO Colletotrichum gloeosporioides (Penz) SACC
Anthracnose caused by the fungal pathogen Colletotrichum gloeosporioides causes serious post harvest losses of avocado fruit worldwide. Typically, infections are initiated in the field on unripe fruit, but remain quiescent as germinated appressoria until fruit ripening. Over the past two decades pepper spot, a pre-harvest disease also caused by C. gloeosporioides, has been reported on 'Hass' av...
متن کاملpelB gene in isolates of Colletotrichum gloeosporioides from several hosts.
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...
متن کاملLocal modulation of host pH by Colletotrichum species as a mechanism to increase virulence.
The phytopathogenic fungus Colletotrichum gloeosporioides produces one pectate lyase (PL) that is a key virulence factor in disease development. During growth of C. gloeosporioides, Colletotrichum acutatum, and Colletotrichum coccodes in acidified yeast extract medium, the fungus secreted ammonia and increased the medium pH. Ammonia accumulation and the consequent pH change increased as a funct...
متن کاملComparison of Colletotrichum gloeosporioides Isolates from Various Avocado Producing Areas
Eighty six isolates of C. gloeosporioides isolated from avocados from various production areas were compared using fruit inoculation studies. Differences were observed, and isolates could be grouped into three groups based on lesion size. These results are preliminary and further investigation must be carried out to confirm these findings.
متن کاملTranscriptomic Analysis of Avocado Hass (Persea americana Mill) in the Interaction System Fruit-Chitosan-Colletotrichum
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...
