| dc.description.abstract | The electrophoretic karyotype of the filamentous fungus Penicillium purpurogenum has been resolved. Using contour-clamped homogeneous electric field gel electrophoresis, five chromosomal bands were separated, with estimated sizes of 7.1, 5.2, 3.7, 2.9 and 2.3 Mbp, giving a total genome size of 21.2 Mbp. To our knowledge, this is the smallest Penicillium genome determined so far. By Southern blots and using homologous probes, the chromosomal location of five xylanolytic genes from P. purpurogenum was determined: axel (acetyl xylan esterase I), xynB (endoxylanase B) and abf1 (arabinofuranosidase 1) in chromosome I, xynA (endoxylanase A) in chromosome II, and axeII (acetyl xylan esterase II) in chromosome Ill. This is the first study where the location of xylanase genes in a Penicillium genome has been established. (C) 2001 Federation of European Microbiological Societies.
