Current genetic differentiation of Coffea canephora Pierre ex A. Froehn in the Guineo-Congolian African zone : cumulative impact of ancient climatic changes and recent human activities [PDF]

, 2009
Background: Among Coffea species, C. canephora has the widest natural distribution area in tropical African forests. It represents a good model for analyzing the geographical distribution of diversity in relation to locations proposed as part of the ...

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

Plant 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 ...

Autotetraploid Coffea canephora and Auto-Alloctaploid Coffea arabica From In Vitro Chromosome Set Doubling: New Germplasms for Coffea

Frontiers in Plant Science, 2020
Polyploidy is more than two chromosomal sets per nucleus, as the allotetraploid Coffea arabica. Due to allotetraploidy, C. arabica shows different phenotypes compare to diploid Coffea species, highlighting by beverage quality produced from its grains ...

Genomic Offset Analyses: Mind Your Climate Variables

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Recent methods based on genomic offset (GO) statistics aim to quantify the risk of non‐adaptation of populations to future climates. This study assesses how well genomic offset values correspond to population variation in fitness, depending on the methods and climate data used.

Analysis of DREB1D gene sequence in different Coffea genotypes : S03P07 [PDF]

, 2013
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

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

Pest Management Science, Volume 82, Issue 6, Page 5757-5766, June 2026.
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.
