Gummy stem blight (GSB) caused by the ascomycete fungus Didymella bryoniae (Auersw.) Rehm is an important disease of melon. Molecular markers linked to resistance would be useful for melon breeding programs. The amplified fragment length polymorphism (AFLP) technique and bulk segregant analysis were used to identify molecular markers linked to the resistance of melon to Didymella bryoniae. Segregation analysis of F2 progeny from a cross of PI 420145, a resistant line, and PI 136170, a susceptible line, showed that resistance to GSB was controlled by a dominant gene. One AFLP marker, E-TG/M-CTC200, was identified that is tightly linked to GSB resistance gene at a distance of 2.0 cM. To our best knowledge, this is the first report of AFLP markers linked to GSB resistance in melon. The identification of AFLP markers provides a step toward the use of marker-assisted selection and the characterization of the gene encoding resistance to GSB in melon.

Insight Into

Amplified fragment length polymorphism (AFLP) fingerprinting of clinical isolates of Chlamydia trachomatis serovars D, E, and F showed a low percentage of genetic heterogeneity, but clear differences were found. Isolates from index patients and partners had identical AFLP patterns and AFLP markers. Characterization of these AFLP markers could give more insight into the differences in virulence and clinical course of C. trachomatis infections.
