PCR-Based Detection for the Quarantine Fungus , a Biosecurity Threat to the Coffee () Industry Worldwide.

Coffee berry disease is caused by , a quarantine fungus still absent from most coffee-producing countries. Given the potential adverse effects on coffee berry production, it is a severe worldwide threat to farmers and industry. Current biosecurity management focuses on exclusion by applying quarantine measures, including the certification of coffee plants and their products.

Taxonomic and Functional Diversity of Flower-Visiting Insects in Coffee Crops.

Despite the important role that flower-visiting insects play in agricultural production, none of the previous studies of coffee pollinators in Colombia have incorporated functional diversity into their analysis. Therefore, this study aimed to quantify the abundance, richness, and functional diversity of insects that visit flowers in coffee crops. Twenty-eight plots were selected among five sites in the north, center, and south of Colombia.

Genome sequence of Berk. and Br. (Race I), the causal agent of coffee leaf rust, isolate from Risaralda, Colombia.

Coffee leaf rust, caused by the fungus (Basidiomycota; Pucciniomycota) is a devastating disease spread worldwide. To improve the available genomes, we use PacBio HiFi sequencing enhanced by Dovetail Omni-C chromatin conformation capture to assemble a highly contiguous 747.98 Mb genome of an isolate collected from .

Identification of sources of male sterility in the Colombian Coffee Collection for the genetic improvement of Coffea arabica L.

In coffee (Coffea arabica L.), male sterility is a prerequisite for the exploitation of heterosis since it provides an efficient and reliable method for the production of hybrid seeds. Given its relevance, the objective of this study was to identify male-sterile genotypes within the Colombian Coffee Collection that can be used in genetic improvement.

A coffee berry borer (Hypothenemus hampei) genome assembly reveals a reduced chemosensory receptor gene repertoire and male-specific genome sequences.

Coffee berry borer-CBB (Hypothenemus hampei) is a globally important economic pest of coffee (Coffea spp.). Despite current insect control methods for managing CBB, development of future control strategies requires a better understanding of its biology and interaction with its host plant.

Tracing the Lineage of Two Traits Associated with the Coat Protein of the : Silencing Suppression and HR Elicitation in Species.

In this paper we have characterized the lineage of two traits associated with the coat proteins (CPs) of the tombusvirids: Silencing suppression and HR elicitation in species. We considered that the tombusvirid CPs might collectively be considered an effector, with the CP of each CP-encoding species comprising a structural variant within the family. Thus, a phylogenetic analysis of the CP could provide insight into the evolution of a pathogen effector.

Biology, Thermal Requirements, and Estimation of the Number of Generations of Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae) in the State of São Paulo, Brazil.

Coffee culture, one of the main agricultural activities in Brazil, has undergone recent negative impacts due to unfavorable climate conditions, with a subnormal rainy period and increased temperatures during the second half of 2015. The coffee berry borer Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae) is one of the main insect pests of coffee crops worldwide. The present research aimed to determine the climate zones for coffee berry borer in the state of São Paulo, based on its thermal requirements.

Effects of the aspartic protease inhibitor from Lupinus bogotensis seeds on the growth and development of Hypothenemus hampei: an inhibitor showing high homology with storage proteins.

The coffee berry borer Hypothenemus hampei is a pest that causes great economic damage to coffee grains worldwide. Because the proteins consumed are digested by aspartic proteases in the insect's midgut, the inhibition of these proteases by transferring a gene encoding an aspartic protease inhibitor from Lupinus bogotensis Benth. to coffee plants could provide a promising strategy to control this pest.

An inhibitor from Lupinus bogotensis seeds effective against aspartic proteases from Hypothenemus hampei.

The coffee berry borer, Hypothenemus hampei (Ferrari), is one of the most devastating coffee pests (Coffea arabica L.) worldwide. Digestion in the midgut of H.

Detection and Identification of a Group 16SrIII-Related Phytoplasma Associated with Coffee Crispiness Disease in Colombia.

Coffee crispiness ("crespera"), a disease of uncertain etiology, has been endemic in coffee (Coffea arabica L.) plantations in Colombia for at least 60 years. Symptoms typically consist of bud proliferation, abundant short and narrow leaves, phyllody, floral abortion, monospermic fruit, and dwarfing of plants.
