Characterization of differential coffee tree hostsfor Hemileia vastatrix Berk. et Br. with RAPD markers

open access: yesCrop Breeding and Applied Biotechnology, 2004
Eighteen clones of differential coffee tree hosts for Hemileia vastatrix Berk. et Br. were characterized with RAPD markers. The genetic distances were estimated and the genealogical origin of the clones compared to data of markerbased clusters.

Effects of shade on growth, production and quality of coffee (Coffea arabica) in Ethiopia [PDF]

open access: yes, 2011
The research work was conducted to evaluate the effect of shade on growth and production of coffee plants. To achieve this, growth and productivity of coffee plants growing under shade trees were compared with those of coffee plants growing under direct ...

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, Volume 16, Issue 5, Page 906-920, May 2026.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

New Dammarane Triterpenoids, Caffruones A–D, from the Cherries of Coffea arabica

open access: yesNatural Products and Bioprospecting, 2018
In present study, four new dammarane-type triterpenoids, namely caffruones A–D (1–4), were isolated from the cherries of Coffea arabica. Their structures were elucidated by extensive spectroscopic analysis including 1D, 2D NMR (HSQC, HMBC, 1H–1H COSY ...

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 ...
