Evaluation of beverage quality and green bean physical characteristics of selected Arabica coffee genotypes in Kenya [PDF]

open access: yes, 2009
Physical characteristics of green coffee bean have been reported to affect beverage quality to some extent. The objective of this study was to assess the beverage quality and green bean physical characteristics of forty two arabica coffee genotypes and ...

A national crop wild relative checklist for Zimbabwe reveals edible crop wild relative diversity of regional and global importance

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Crop wild relatives (CWR) in Zimbabwe are reservoirs of beneficial agronomic traits, yet they remain under‐documented and poorly conserved. This study developed Zimbabwe's first national CWR checklist based on a conceptual framework combining floristic, ecological and ethnobotanical data, revealing over 2700 taxa, with nearly 1000 edible species ...

RNA-Seq analysis and de novo transcriptome assembly of Coffea arabica and Coffea eugenioides : P0068 [PDF]

open access: yes, 2013
Coffee is one of the most important agricultural commodites in the world. Coffea arabica, an allotetraploid from a recent hybridization of two diploid species (C.canephora and C.eugenioides) is responsible for 70% of world commercial production.

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Structure and Distribution of Centromeric Retrotransposons at Diploid and Allotetraploid Coffea Centromeric and Pericentromeric Regions

open access: yesFrontiers in Plant Science, 2018
Centromeric regions of plants are generally composed of large array of satellites from a specific lineage of Gypsy LTR-retrotransposons, called Centromeric Retrotransposons.

AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,

Molecular Genetic Diversity Study of Forest Coffee Tree (Coffea arabica L.) Populations in Ethiopia: Implications for Conservation and Breeding [PDF]

open access: yes, 2005
Coffee provides one of the most widely drunk beverages in the world, and is a very important source of foreign exchange income for many countries. Coffea arabica, which contributes over 70 percent of the world's coffee productions, is characterized by a ...

Leaf Extracts of Coffea racemosa Inhibit Trypsin Activity and Affect Larval Development in Spodoptera frugiperda and Diatraea saccharalis

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Leaf extracts of Coffea racemosa inhibit digestive trypsins and impair the development of two major lepidopteran pests, Spodoptera frugiperda and Diatraea saccharalis. While both species showed significant enzymatic inhibition, biological responses differed markedly. D. saccharalis exhibited high mortality, whereas S.

Analysis of CcDREB1D promoter region from drought-tolerant and susceptible clones of Coffea canephora by homologous genetic transformation of Coffea arabica [PDF]

open access: yes, 2014
In several plant species, the DREB genes play a key role in responses to abiotic stress. Since the development of molecular markers is one of the major goals for accelerating breeding programs, a study was done to evaluate the sequence variability of the

Cross‐Species Reprogramming of Developmental Plasticity and Metabolic Rewiring via Banana‐Derived WUS2 Developmental Regulator

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant regeneration is governed by intrinsic gene regulation and phytohormonal cues. WUSCHEL (WUS) gene promotes regeneration, but its broader functional role remains unexplored. Here, we demonstrate that the constitutive and inducible expression of banana‐derived WUS2 (GN‐WUS2) enhances regeneration in Nicotiana tabacum (tobacco) and Musa ...
