Common foliar fungi of Populus trichocarpa modify Melampsora rust disease severity

Effect of mulching on severity of mulberry rust disease

Evolutionary Quantitative Genomics of Populus trichocarpa.

Forest trees generally show high levels of local adaptation and efforts focusing on understanding adaptation to climate will be crucial for species survival and management. Here, we address fundamental questions regarding the molecular basis of adaptation in undomesticated forest tree populations to past climatic environments by employing an integrative quantitative genetics and landscape genom...

Transcript 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...

Genetic and physical mapping of Melampsora rust resistance genes in Populus and characterization of linkage disequilibrium and flanking genomic sequence

• In an attempt to elucidate the molecular mechanisms of Melampsora rust resistance in Populus trichocarpa , we have mapped two resistance loci, MXC3 and MER , and intensively characterized the flanking genomic sequence for the MXC3 locus and the level of linkage disequilibrium (LD) in natural populations. • We used an interspecific backcross pedigree and a genetic map that was highly saturated...

Identification 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...
