Melampsora larici-populina genome sequenced

From Francis Martin

The DNA sequence of Melampsora larici-populina has been determined by the U.S. Department of Energy DOE Joint Genome Institute (DOE JGI). Annotations of the v1.0 assembly of Melampsora laricis-populina are publicly available at http://www.jgi.doe.gov/Melampsora.
Genome analyses have been carried out by an international consortium comprised of DOE JGI, France’s National Institute for Agricultural Research (F Martin et al., INRA-Nancy), Canadian Forest Service (R Hamelin et al., Laurentian Forestry Centre), and the Bioinformatics & Evolutionary Genomics Division (Rouzé et al., Gent University) in Belgium.

The poplar leaf rust fungus Melampsora is the most devastating and widespread pathogen of poplars, and has limited the use of poplars for environmental and wood production goals in many parts of the world. All known poplar cultivars are susceptible to Melampsora species, and new virulent strains are continuously developing. This disease therefore has a strong potential impact on current and future poplar plantations used for production of forest products (principally pulp and consolidated wood products), carbon sequestration, biofuels production, and bioremediation.
