The maintenance of chromatin in a transciptionally silent state such as heterochromatin at silent mating-type loci. Repression of transcription by altering the structure of chromatin, e.g. by conversion of large regions of DNA into an inaccessible state often called heterochromatin. The initial formation of a transcriptionally silent chromatin structure such as heterochromatin at silent mating-type loci. Any epigenetic process that stops, prevents or reduces the rate of gene expression. Any transcriptional or post-transcriptional process carried out at the cellular level that results in long-term gene inactivation. Repression of transcription at silent mating-type loci by alteration of the structure of chromatin. Any process that increases the frequency, rate, or extent of chromatin silencing at silent mating-type cassette. Chromatin silencing at silent mating-type cassette is the repression of transcription at silent mating-type loci by altering the structure of chromatin. Any process that modulates the frequency, rate, or extent of chromatin silencing at silent mating-type cassette. Chromatin silencing at silent mating-type cassette is the repression of transcription at silent mating-type loci by altering the structure of chromatin. Any process that stops, prevents or reduces the frequency, rate or extent of cellular DNA-dependent transcription.
