Signatures of recombination in clonal lineages of the citrus brown spot pathogen, Alternaria alternata sensu lato.

Most Alternaria spp. are considered asexual but recent molecular evolution analyses of Alternaria mating-type genes show that the mating locus is under strong purifying selection, indicating a possible role in sexual reproduction. The objective of this study was to determine the mode of reproduction of an Alternaria alternata sensu lato population causing citrus brown spot in central Florida.

Development, characterization and linkage analysis of microsatellite loci for the Ascochyta blight pathogen of faba bean, Didymella fabae.

Eighteen microsatellite markers were developed for Didymella fabae, seventeen of which were highly polymorphic among a sample of D. fabae isolates from Syria. Genetic linkage analysis assigned the markers to eight linkage groups.
