“…The stage that results in the characteristic symptoms on aspen leaves is the uredial stage, where uredospores are produced within uredia, yellow or orange pustules usually on the lower side of leaves, in several cycles. The taxonomy of the Melampsora species is complex (Pei and Shang 2005). For the purpose of this study we did not determine the species composition of rusts across the geographic area.…”

According to the geographic mosaic theory of coevolution (GMTC), clines of traits reflecting local co‐adaptation (including resistance genes) should be common between a host and its parasite and should persist across time. To test the GMTC‐assumption of persistent clinal patterns we compared the natural prevalence of two parasites on aspen Populus tremula trees: mining moths of the genus Phyllocnistis and leaf rust Melampsora spp. Damage data were collated from the Swedish National Forest Damage Inventory (2004–2006). In addition, occurrence of the parasites was scored in field conditions in two common gardens in the north and south of Sweden over five growing seasons (2004–2008), then related to biomass (stem height and diameter) and to concentrations of eleven leaf phenolics. Phyllocnistis mainly occurred in the northern garden, a distribution range which was confirmed by the countrywide inventory, although Phyllocnistis was more abundant on southern clones, providing evidence for possible local maladaptation. Melampsora occurred all over the country and in both gardens, but built up more quickly on northern clones, which suggests a centre of local clone maladaptation in the north. Stem growth also followed a clinal pattern as did the concentration of three phenolic compounds: benzoic acid, catechin and cinnamic acid. However, only benzoic acid was related to parasite presence: negatively to Phyllocnistis and positively to Melampsora and it could thus be a potential trait under selection. In conclusion, clines of Phyllocnistis were stronger and more persistent compared to Melampsora, which showed contrasting clines of varying strength. Our data thus support the assumption of the GMTC model that clines exist in the border between hot and cold spots and that they may be less persistent for parasites with an elevated gene flow, and/or for parasites which cover relatively larger hot spots surrounded by fewer cold spots.

Our study evaluated in silico the potential of 14 mitochondrial genes encoding the subunits of the respiratory chain complexes, including cytochrome c oxidase I (CO1), as Basidiomycota DNA barcode. Fifteen complete and partial mitochondrial genomes were recovered and characterized in this study. Mitochondrial genes showed high values of molecular divergence, indicating a potential for the resolution of lower-level relationships. However, numerous introns occurred in CO1 as well as in six other genes, potentially interfering with polymerase chain reaction amplification. Considering these results and given the minimal length of 600-bp that is optimal for a fungal barcode, the genes encoding for the ATPase subunit 6, the cytochrome oxidase subunit 3 and the NADH dehydrogenase subunit 6 have the most promising characteristics for DNA barcoding among the mitochondrial genes studied. However, biological validation on two fungal data sets indicated that no single mitochondrial gene gave a better taxonomic resolution than the ITS, the region already widely used in fungal taxonomy.
