A protocol for transposon insertion sequencing in Schizosaccharomyces pombe to identify factors that maintain heterochromatin

摘要

Transposon insertion sequencing (TIS) is a highly effective method used with bacteria to identify genes important for growth in any condition of interest. Previously, we adapted this method to identify essential genes of the yeast Schizosaccharomyces pombe. Here, we describe modifications used to identify genes necessary for the formation of centromeric heterochromatin.
