Chromosome-length polymorphism in fungi
Article Abstract:
Gel electrophoresis reveals the presence of chromosome-length polymorphism (CLP) in sexual and asexual fungi, probably arising from both mitotic and meiotic processes. The origin and content of most CLPs are uncharacterized, but long tandem repeats such as tracts of rDNA often possess variable lengths. The wide difference in the chromosome length indicates that many karyotypic changes are neutral in fungi. In addition, the new linkage combination of genes is probably helpful for fungi adapting to new environments.

Sub-specific differentiation of intestinal spirochaete isolates by macrorestriction fragment profiling
Article Abstract:
The genotypes of several Serpulina pilosicoli and perpulina hydodysenteriae isolates were analyzed by macrorestriction fragment profiling to investigate sub-species variation and cross-species transmission. A pulsed-field gel electrophoresis (PFGE) was used in macrorestriction fragment profile analysis. Results have shown the potential of PFGE for sub-specific identification of intestinal spirochaetes and the feasibility of cross-transmission among several kinds of genotypes.
