Chromosome reorganization in Candida albicans 1001 strain.

The karotype of Candida albicans 1001, a pathogenic isolate, presents two additional chromosome bands when compared with C. albicans 1006 strain. These two bands were a 2600 kb chromosome located between chromosome group 1-R and chromosome 2 (named chromosome 2*) and a 710 kb small chromosome, called snc due to its similarity in size to the supernumerary chromosome in strain WO-1. A comparison of karyotypes of strains 1001, 1006 and WO-1 has enabled us to conclude that chromosomes 2 and 7 are involved in such a reorganization giving rise to the new chromosome bands of strain 1001. We describe a tentative physical map of C. albicans 1001 based on the previously outlined map of C. albicans strain 1006.
