Effector-Mining in the Poplar Rust Fungus Melampsora larici-populina Secretome
The poplar leaf rust fungus, Melampsora larici-populina has been established as a tree-microbe interaction model. Understanding the molecular mechanisms controlling infection by pathogens appears essential for durable management of tree plantations. In biotrophic plant-parasites, effectors are known to condition host cell colonization. Thus, investigation of candidate secreted effector proteins...
متن کاملPatterns of genomic variation in the poplar rust fungus Melampsora larici-populina identify pathogenesis-related factors
Melampsora larici-populina is a fungal pathogen responsible for foliar rust disease on poplar trees, which causes damage to forest plantations worldwide, particularly in Northern Europe. The reference genome of the isolate 98AG31 was previously sequenced using a whole genome shotgun strategy, revealing a large genome of 101 megabases containing 16,399 predicted genes, which included secreted pr...
متن کاملCharacterization of Two Major Genetic Factors Controlling Quantitative Resistance to Melampsora larici-populina Leaf Rust in Hybrid Poplars: Strain Specificity, Field Expression, Combined Effects, and Relationship with a Defeated Qualitative Resistance Gene.
ABSTRACT Two genetic factors explain a significant proportion of the variability for quantitative resistance to Melampsora larici-populina leaf rust in a Populus deltoides x P. trichocarpa F(1) progeny. One is inherited from P. deltoides and is associated with a defeated qualitative resistance gene R(1), and the other, R(US), is inherited from P. trichocarpa. To assess the potential contributio...
متن کاملTranscript profiling of poplar leaves upon infection with compatible and incompatible strains of the foliar rust Melampsora larici-populina.
To understand key processes governing defense mechanisms in poplar (Populus spp.) upon infection with the rust fungus Melampsora larici-populina, we used combined histological and molecular techniques to describe the infection of Populus trichocarpa x Populus deltoides 'Beaupré' leaves by compatible and incompatible fungal strains. Striking differences in host-tissue infection were observed aft...
متن کاملIdentification and characterization of differentially expressed genes during incompatible interaction between the foliar rust Melampsora larici-populina and poplar.
Poplars are extensively cultivated worldwide, and their susceptibility to the foliar rust fungus leads to considerable damages in plantations. To better understand the molecular basis of poplar responses to the foliar rust, suppression subtractive hybridization was used to identify the potential important or novel genes involved in the Populus szechuanica infection by Melampsora larici-populina...
