Inoculation and Evaluation of Hemileia vastatrix Under Laboratory Conditions

, 2023
AbstractThe coffee leaf rust, a disease caused by the biotrophic fungusHemileia vastatrix, is one of the main limitations in coffee production today as it causes significant economic losses to the coffee production sector. Genetic improvement is an option to solve these problems.

Climate requirements for cultivated Liberica coffee (Coffea liberica) and consequences for its use and development as a crop species

PLANTS, PEOPLE, PLANET, EarlyView.
The global coffee industry, supporting 25 million smallholder farmers, is vulnerable to climate change. Diversifying the coffee species portfolio beyond Arabica and robusta is a promising intervention. Liberica coffee could provide adaptive capacity, although its climate parameters for cultivation are poorly known.

Phylogenetic relationship of coffee leaf rust in the central jungle of Peru

Acta Agronómica, 2022
Coffee leaf rust is the main disease that causes significant losses in Coffea arabica. In Peru, this disease caused epidemics between 2008 and 2013 with production losses of 35 %. The objective was to identify H.

Secondary Metabolites of Calonectria hemileiae Inhibit Hemileia vastatrix Urediniospore Germination: Evidence for Chemical Mediation in a Mycoparasitic Interaction

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Calonectria hemileiae, an antagonist of the coffee leaf rust pathogen Hemileia vastatrix, produces low‐molecular weight secondary metabolites that inhibit urediniospore germination. These metabolites likely mediate interfungal interactions and show potential for the development of biofungicides against coffee leaf rust.

Leaf Fungal Microbiome Is Modulated by Interspecific Hybridization Events Between Coffea Species

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Increasing attention has been given to the host phylogeny and domestication roles in shaping plant‐associated microbiomes. However, the interspecific effects of hybridization on microbial communities remain poorly understood. We investigated the effects of interspecific hybridization on the composition, diversity, ecological organization, and ...

Association of Agro‐Morphological Traits With Cup Quality in Accessions of Coffea arabica L. From the INIA Germplasm Bank, Peru

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT In recent years, Peruvian coffee production has increasingly focused on specialty coffees, with cup quality (CQ) as a key criterion. While previous studies have characterized the Coffee Germplasm Collection of the National Institute of Agrarian Innovation (CGC‐INIA), few studies have analyzed coffee cup quality.

Thermal sensitivity and yield of Arabica coffee under climatic variability

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield is influenced by climatic factors, with temperature and water availability being key determinants. This study aimed to evaluate the effects of climate variability on the yield of Arabica coffee (Coffea arabica L.) cultivars across phenological phases and to validate an agrometeorological model at local and regional scales using ...
