| Abstract |
Cochliobolus heterostrophus was transformed with a plasmid (pH1S) containing a bacterial gene (hygB), which confers resistance to the antibiotic hygromycin B when under control of an 838-bp fragment of promoter 1 from C. heterostrophus. The plasmid integrated at either homologous (52% single copy, 33% tandemly repeated copies) or ectopic (4% single copy, 11% tandemly repeated copies) sites on different chromosomes, resulting in four distinct configurations of integrated DNA. All four configurations were highly stable during mitotic growth; virtually no loss of integrated DNA was detected after five subcultures on nonselective medium or after seven cycles of pathogenesis on maize, the normal host of this fungus. However, deletion of integrated DNA was detected after eight or more disease cycles. (Copyright (c) Springer-Verlag 1991.) |
