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. A total of 515 expressed sequence tags (ESTs) with high quality were obtained and clustered into 66 contigs and 75 singletons to give a set of 141 uniESTs.
