Diverse roles for histone H2A modifications in DNA damage response pathways in yeast.

abstract：:In Arabidopsis thaliana, significant efforts to determine the extent of genomic variation between phenotypically divergent accessions are under way, but virtually nothing is known about variation at the transcription level. We used microarrays to examine variation in transcript abundance among three inbred lines and t...
