3RAD‐Guided SNP Discovery for Species Identification and Conservation of the Medicinal Southern African Tree Genus Greyia Hook. & Harv.

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
A two‐phase SNP discovery and assay‐development strategy was used to resolve species boundaries within the tree genus Greyia, as overlapping phenotypes and distributions limit accurate identification. From 47,726 genome‐wide SNPs generated by 3RAD sequencing, a diagnostic 23‐SNP Type panel was developed and validated, successfully distinguishing G ...

SSR cross-amplification and variation within coffee trees (Coffeaspp.)

open access: yesGenome, 2004
Primer sets were developed from 85 Coffea arabica sequences in addition to 25 already published primer sets. They were subsequently used for amplification in six African Coffea species: Coffea canephora (CAN), Coffea eugenioides (EUG), Coffea heterocalyx (HET), Coffea liberica (LIB), Coffea sp. Moloundou (MOL) and Coffea pseudozanguebariae (PSE).

Methane Emissions From Flame Curtain Pyrolysis (Kon‐Tiki)

open access: yesGCB Bioenergy, Volume 18, Issue 4, April 2026.
Flame curtain pyrolysis enables decentralized biochar production, but its net climate benefit depends on the magnitude of methane emissions caused during production. Methane emissions were below 5 g CH4 kg−1 biochar for dry feedstocks but increased for moist feedstocks. Pyrolysis emitted less methane than open burning of wheat straw. ABSTRACT Pyrogenic

Soil organic matter and F1 hybrid cultivar influence Coffea arabica yields in south‐central Guatemala

open access: yesAgronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Smallholders produce 60% of global coffee (Coffea arabica) supply but lack recommendations on nutrient management. We tested hypothesized N‐ and K‐driven yield gaps using on‐farm omission trials established across 21 fields in Guatemala. The effects of a single and combined application of N (285 kg ha−1) and K (350 kg ha−1) were evaluated for ...

The polyphenolic and hydroxycinnamate contents of whole coffee fruits from China, India and Mexico [PDF]

open access: yes, 2013
Air dried whole coffee fruits, beans and husks from China, India and Mexico were analysed for their chlorogenic acids (CGA), caffeine, and polyphenolic content. Analysis was by HPLC and Orbitrap exact mass spectrometry.
