Data Mining of the Coffee Rust Genome [PDF]

open access: yes, 2012
The genomes of nine isolates of _Hemileia vastatrix_, the causal agent of coffee leaf rust were sequenced by Illumina and 454. Quality control, cleaning and _de novo_ assemblies of data were performed.

Characterization of coffee cultivars leaf rust-resistant subjected to framework pruning [PDF]

open access: yes, 2018
The goal of our work was to evaluate physiological and agronomic traits, as well as the relationship between these traits in coffee cultivars coming from a germplasm supposedly resistant to leaf rust, and their response to framework pruning.

Correlation Between Secondary Metabolites of Leaf and the Resistance to Leaf Rust (Hemileia vastatrix) on Several Arabica Coffee Clones

open access: yesIlmu Pertanian (Agricultural Science), 2019
Indicator of coffee resistance to leaf rust attack (Hemileia vastatrix) is needed to select superior coffee plants resistant to biotic stress. This study aims to find the relationship between the content of secondary metabolites and the intensity of leaf

Genotypic and Phenotypic Correlations between Leaf-Rust Disease and Leaf Morphology and its Ratio in Arabica Coffee

open access: yesJurnal Ilmu Pertanian Indonesia, 2020
Selection parameter in coffee breeding for leaf rust (Hemeleia vastatrix) resistance is very important. Breeders used leaf-rust severity and leaf-rust incidence as parameters of direct selection.

Abnormal germling development by brown rust and powdery mildew on cer barley mutants [PDF]

open access: yes, 2001
The barley leaf rust fungus forms appressoria over host leaf stomata and penetrates via the stomatal pore. High levels of avoidance to leaf rust fungi have been described in some wild accessions of Hordeum species where a prominent wax layer on the ...
