Abstract

A minisatellite was identified in the intron of the ATP synthase of the filamentous fungus Botrytis cinerea, and it was named MSB1. This isthe second fungal minisatellite described to date. Its 37-bp repeat unit is AT-rich, and it is found at only one locus in the genome. The introns of 47 isolates of Botrytis species were sequenced. The number of tandem repeats varied only from 5 to 11, but there were many repeat variants. The structure of MSB1 is peculiar: the variants are in the same physical order in all individuals, and this order follows the mostparsimonious tree. These original characteristics, together with a total lack of recombination between alleles of the flanking regions, suggest that MSB1 probably mutates by slippage. MSB1 was found in the intron of the ATP synthase of all of the Botrytis species analyzed, but the repeat unit was not found in any other genus examined, including Sclerotinia, which is the genus closest to Botrytis.
