The insect parasitoid Prorops nasuta has been introduced from Africa to many coffee-producing countries in an attempt to control the coffee berry borer. In this paper, we report on the sequencing of the ITS LSU-rDNA and beta-tubulin loci used to identify a fungus isolated from the cuticle of a P. nasuta that emerged from coffee berries infected with the(More)
Postharvest fruit conservation relies on low temperatures and manipulations of hormone metabolism to maintain sensory properties. Peaches are susceptible to chilling injuries, such as ‘woolliness’ that is caused by juice loss leading to a ‘wooly’ fruit texture. Application of gibberellic acid at the initial stages of pit hardening impairs woolliness(More)
The entomopathogenic fungus Beauveria bassiana was re-isolated from surface sterilized pieces of the cocoa pod outer section and peduncle, two and three months after flowers of greenhouse cocoa plants were hand-pollinated and sprayed with a 1x10 7 mL-1 suspension of B. bassiana conidia. The colonization frequency of B. bassiana on cocoa pods was 0.8% and(More)
Aspergillus oryzae NRRL 35191 was isolated as an endophyte from coffee leaves and found to produce kojic acid (KA) in culture. When inoculated into cacao seedlings (Theobroma cacao), A. oryzae grew endophytically and synthesized KA in planta. Cacao seedlings inoculated with A. oryzae produced higher levels of caffeine than non-inoculated ones. Aspergillus(More)
A doença de Whipple é uma doença multissistémica rara cujo agente causal é um bacilo gram-positivo, Tropheryma whippelii, da família das Actinobacterias e grupo Actinomycetes. Por ter formas de apresentação variadas e por se tratar de uma doença rara é muitas vezes diagnosticada tardiamente. WHIPPLE'S DISEASE – A challenging Diagnosis Whipple's Disease is a(More)
