New Races of Hemileia vastatrix Detected in Peruvian Coffee Fields

Agronomy
Coffee leaf rust (CLR), a fungal disease caused by Hemileia vastatrix, represents Peru’s most significant threat to coffee production. The CLR epidemic (2012–2013) led Peru to implement an emergency plan under which coffee plantations underwent renewal using rust-resistant varieties derived from a Timor hybrid (HDT; Coffea arabica × canephora hybrid ...

Capillary electrophoresis as a tool for genotyping SH3 mediated coffee leaf rust resistance

Scientia Agropecuaria, 2021
Coffee is an important agricultural commodity in the world. However, it is susceptible to Hemileia vastatrix (Hv), an obligatory biotrophic fungus that causes coffee leaf rust (CLR).

Identification of miRNAs as Mediators of Coffea arabica Resistance to Hemileia vastatrix

, 2017
Coffee leaf rust, caused by the biotrophic fungus Hemileia vastatrix is the most widespread disease of Coffea arabica. Resistance of coffee to H. vastatrix is mediated by gene-for-gene interactions that are conditioned by at least nine major dominant genes (SH1 – SH9) singly or associated.

Shade effects on coffee rust (Hemileia vastatrix)

, 2019
To better understand shade effects on coffee rust (Hemileiavastatrix), we studied pathogen dispersal, deposition, germination, penetration, colonization and sporulation under shade and full sun conditions (Figure). Studies were conducted from 2008 in the CATIE agroforestry system long term trial, at Turrialba, Costa Rica, at 600 m of altitude.

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

Crop 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.

Leaf Mineral Composition of Coffee Infected by a Hemileia vastatrix Fungus in Bondowoso, East Java

Coffee and Cocoa Research Journal, 2019
Leaf rust disease caused by Hemileia vastatrix fungus may become an important issue on highland coffee (Coffea arabica) especially related to the progressive increase in terms of global temperature.
