Inheritance of coffee leaf rust resistance and identification of AFLP markers linked to the resistance gene. The most important disease of Coffea arabica is coffee leaf rust caused by the fungus Hemileia vastatrix. The purpose of this study was to characterize the inheritance of coffee resistance gene(s) to... ... Repositório: BDPA Ano de publicação: 2010
Manganese phosphite in Coffee defence against Hemileia vastatrix, the coffee rust fungus: biochemical and molecular analyses. Phosphites (Phi) are inorganic salts of phosphorous acid that have been used as resistance elicitors to activate mechanisms underlying plant defence. This study assessed the effectiveness of manganese... ... Repositório: BDPA Ano de publicação: 2016
Effects of UV-B radiation on Lecanicillium spp., biological control agents of the coffee leaf rust pathogen. Coffee leaf rust is the main disease of coffee and its causal agent is naturally hyperparasited by Lecanicillium lecanii, indicating its potential for biocontrol. Ultraviolet-B (UV-B) radiation is an... ... Repositório: BDPA Ano de publicação: 2014
A new chitinase-like xylanase inhibitor protein (XIP) from coffee (Coffea arabica) affects Soybean Asian rust (Phakopsora pachyrhizi) spore germination. Asian rust (Phakopsora pachyrhizi) is a common disease in Brazilian soybean fields and it is difficult to control. In order to find a biochemical candidate to such enterprise, a new chitinase-like xyl... ... Repositório: BDPA Ano de publicação: 2010
On the accuracy of threshold genomic prediction models for leaf miner and leaf rust resistance in arabica coffee. Obtaining resistance cultivars for leaf miner and leaf rust are the main important strategy of Brazil?s national coffee breeding program. The narrow genetic basis, and founder effect consequences, lea... ... Repositório: BDPA Ano de publicação: 2023
Coffee genotypes morphophysiological adaptation under coffee leaf rust biotic stress. The identification of morphophysiological traits responsible for a better plant behavior when infected is useful for cultivar selection, and become crucial for breeding. We investigated the morphophys... ... Repositório: BDPA Ano de publicação: 2021
High-density genetic mapping for coffee leaf rust resistance. Coffee leaf rust caused by the fungus Hemileia vastatrix causes considerable economic losses for coffee producers. Although agrochemical products can provide sufficient disease control, the use of res... ... Repositório: BDPA Ano de publicação: 2011
Effect of sheep manure on coffee leaf rust. The objective of the present work was to evaluate the effect of sheep manure on the development of coffee leaf rust under greenhouse conditions. The seedlings of coffee cv. Mundo Novo were obtained fr... ... Repositório: BDPA Ano de publicação: 2005
New vegetation index for monitoring coffee rust using sentinel-2 multispectral imagery. Coffee Rust (Hemileia vastatrix) is considered the primary coffee disease in the world. The pathogenic fungus can find favorable environmental conditions in different countries, constantly threatening... ... Repositório: BDPA Ano de publicação: 2023
Biphasic haustorial differentiation of coffee rust (Hemileia vastatrix race II) associated with defense responses in resistant and susceptible coffee cultivars. The objective of this study was to assess whether defence responses in coffee (Coffea arabica) were linked to a specific developmental stage of the rust fungus Hemileia vastatrix. Histological observa... ... Repositório: BDPA Ano de publicação: 2009
