Genetic diversity of coffee germplasm in Sierra Leone: implications for conservation and breeding programs

Beverage Plant Research, 2023
Global coffee production is dominated by Coffea arabica (Arabica coffee) and C. canephora (Robusta coffee) due to their relatively high-yielding and quality attributes as opposed to other coffee species.

The genome and population genomics of allopolyploid Coffea arabica reveal the diversification history of modern coffee cultivars

bioRxiv, 2023
Coffea arabica, an allotetraploid hybrid of C. eugenioides and C. canephora, is the source of approximately 60% of coffee products worldwide, and its cultivated accessions have undergone several population bottlenecks.

Microbiomes associated with Coffea arabica and Coffea canephora in four different floristic domains of Brazil

Scientific Reports, 2023
Brazilian coffee production relies on the cultivation of Coffea arabica and Coffea canephora . Climate change has been responsible for the decreasing yield of the crops in the country yet the associated microbial community can mitigate these effects by ...

Embryonic abnormalities and genotoxicity induced by 2,4-dichlorophenoxyacetic acid during indirect somatic embryogenesis in Coffea

Scientific Reports, 2023
Indirect somatic embryogenesis (ISE) is a morphogenetic pathway in which somatic cells form callus and, later, somatic embryos (SE). 2,4-dichlorophenoxyacetic acid (2,4-D) is a synthetic auxin that promotes the proliferation and dedifferentiation of ...

Impact of different roasting conditions on the chemical composition, antioxidant activities, and color of Coffea canephora and Coffea arabica L. samples

Heliyon, 2023
This work aimed to evaluate the physicochemical changes during the roasting process of Robusta and Arabica coffee. The highest content of total phenolics was detected in roasted coffee at temperatures of 135 °C/20.20 min, 210 °C/9.02 min, 210 °C/11.01 ...

Targeted and Untargeted Mass Spectrometry-Based Metabolomics for Chemical Profiling of Three Coffee Species

Molecules, 2022
While coffee beans have been studied for many years, researchers are showing a growing interest in coffee leaves and by-products, but little information is currently available on coffee species other than Coffea arabica and Coffea canephora.

Overexpression of Water-Responsive Genes Promoted by Elevated CO2 Reduces ROS and Enhances Drought Tolerance in Coffea Species

International Journal of Molecular Sciences, 2023
Drought is a major constraint to plant growth and productivity worldwide and will aggravate as water availability becomes scarcer. Although elevated air [CO2] might mitigate some of these effects in plants, the mechanisms underlying the involved ...
