Genome-wide identification of NBS resistance genes in Populus trichocarpa Inra
Kohler, A.; Rinaldi, C.; Duplessis, S.; Baucher, M.; Geelen, D.; Duchaussoy, F.; Meyers, BC; Boerjan, W.; Martin, F..
As the largest class of disease resistance R genes, the genes encoding nucleotide binding site and leucine-rich repeat proteins (“NBS-LRR genes”) play a critical role in defending plants from a multitude of pathogens and pests. The diversity of NBS-LRR genes was examined in the Populus trichocarpa draft genome sequence. The NBS class of genes in this perennial tree is large and diverse, comprised of ∼400 genes, at least twice the complement of Arabidopsis. The NBS family can be divided into multiple subfamilies with distinct domain organizations. It includes 119 Coiled-Coil-NBS-LRR genes, 64 TIR-NBS-LRR genes, 34 BED-finger-NBS-LRR, and both truncated and unusual NBS- and NBS-LRR-containing genes. The transcripts of only 34 NBS-LRR genes were detected in...

Transcript Profiling of Poplar Leaves upon Infection with Compatible and Incompatible Strains of the Foliar Rust Melampsora larici-populina Inra
Rinaldi, C.; Kohler, A.; Frey, P.; Duchaussoy, F; Ningre, F; Couloux, A.; Wincker, P; Le Thiec, D.; Fluch, S.; Martin, F.; Duplessis, S..
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 'Beaupre' leaves by compatible and incompatible fungal strains. Striking differences in host-tissue infection were observed after 48-h postinoculation (hpi) between compatible and incompatible interactions. No reactive oxygen species production could be detected at infection sites, while a strong accumulation of monolignols occurred in the incompatible interaction after 48 hpi, indicating a late plant response once the fungus already penetrated host cells to form haustorial infection...
