Genetic dissection of histone function.

Author information

Department of Microbiology, University of Virginia, Charlottesville, USA.


Mutational analysis is an essential tool for understanding the functions of genes within a living organism. The budding yeast Saccharomyces cerevisiae provides an excellent model system for dissecting the genetics of histone function at the molecular and cellular levels. A simple gene organization, plus a wide variety of genetic strategies, makes it possible to directly manipulate a specific histone gene in vitro and then examine the expression of mutant alleles in vivo. Recent methods for manipulating the yeast histone genes have been designed to facilitate both side-directed analysis of structure/function relationships and unbiased screens targeted at specific functional pathways. The conservation of histone and nucleosome structure throughout evolution means that the principles discovered through genetic studies in yeast will be broadly applicable to the chromatin of more complex eukaryotes.
