摘要：

In the yeast Candida rugosa the lipase isozymes are encoded by a family of genes, five of which have been cloned and sequenced in our laboratory. In this paper we report on the identification and preliminary characterization of two new related sequences, thus extending this multigene family to seven members. The total DNA content of Candida cells was estimated by laser flow-cytometry at about 20 Mb. Eight chromosomes with sizes ranging between 100 kb and 2.1 Mb, as determined by comparison with S. cerevisiae chromosomal bands, were resolved by pulsed-field gel electrophoresis. The lipase-encoding genes were localized on chromosome I, therefore suggesting that they have originated through multiple duplication events of an ancestral gene.
