RESUMO

A chromosome rearrangement has been isolated and characterized in Sordaria brevicollis. Crosses to spore color mutants on each of the seven linkage groups have enabled the breakpoints to be mapped. The simplest hypothesis to account for the results is that a piece of linkage group VI has been translocated to linkage group V and inserted 2.7 map units from its centromere. Previous reports of markers on this linkage group with centromere distances greater than 2.7 units make it unlikely that the translocation is quasiterminal.
