Meiotic behavior of a supernumerary chromosome in Magnaporthe oryzae.

Abstract

A 1.2-Mb DNA band from an isolate of Magnaporthe oryzae was detected in a pulsed-field gel. A chromosomal entity corresponding to this band was observed at the mitotic metaphase stage. This minichromosome, carrying many transposable elements and two telomeres, was transmitted to ascosporic F(1) cultures in a non-Mendelian manner with frequent changes in its size and number. Segregation analysis with RFLP markers indicated that the minichromosome underwent structural rearrangements, such as deletion and duplication, not only during meiosis but also after meiosis. An ectopic sister chromatid recombination may cause the size variation of the minichromosomes.
