The modification of histone H3 by addition of one or more methyl groups to lysine at position 4 of the histone.

Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

Any process that contributes to the maintenance of proper telomeric length and structure by affecting and monitoring the activity of telomeric proteins, the length of telomeric DNA and the replication and repair of the DNA. These processes includes those that shorten, lengthen, replicate and repair the telomeric DNA sequences.

Repression of transcription of telomeric DNA by altering the structure of chromatin.

Repression of transcription of telomeric DNA by altering the structure of chromatin.

The methylation of peptidyl-lysine to form peptidyl-N6,N6-dimethyl-L-lysine.

The methylation of peptidyl-lysine to form peptidyl-N6,N6-dimethyl-L-lysine.

The process in which cells that are products of meiosis acquire the specialized features of ascospores. Ascospores are generally found in clusters of four or eight spores within a single mother cell, the ascus, and are characteristic of the ascomycete fungi (phylum Ascomycota).

Repression of transcription at silent mating-type loci by alteration of the structure of chromatin.

Any process that activates or increases the frequency, rate or extent of the addition of an acetyl group to a histone protein.

Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter as a result of a stimulus indicating the organism is under stress. The stress is usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation).

Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter as a result of a stimulus indicating the organism is under stress. The stress is usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation).

The modification of histone H3 by addition of two methyl groups to lysine at position 4 of the histone.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

The modification of histone H3 by addition of one or more methyl groups to lysine at position 4 of the histone.

The modification of histone H3 by addition of three methyl groups to lysine at position 4 of the histone.

Any process that modulates the frequency, rate or extent of chromatin organization.

Any process that modulates the frequency, rate or extent of meiotic DNA double-strand break formation.

The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

The modification of histones by addition of methyl groups.

The process in which a multicellular organism, a unicellular organism or a group of unicellular organisms grow in a threadlike, filamentous shape.

The process whose specific outcome is the progression of the aggregate over time, from its formation to the point when a slug is formed. Aggregate development begins in response to starvation and continues by the chemoattractant-mediated movement of cells toward each other. The aggregate is a multicellular structure that gives rise to the slug.

A reversible switch of a cell from one cell type or form to another, at a frequency above the expected frequency for somatic mutations. Phenotypic switching involves changes in cell morphology and altered gene expression patterns. For example, Candida albicans switches from white cells to opaque cells for sexual mating. Phenotypic switching also occurs in multicellular organisms; smooth muscle cells (SMCs) exhibit phenotypic transitions to allow rapid adaption to fluctuating environmental cues.

Any process that modulates the frequency, rate or extent of gene expression; the process is mitotically or meiotically heritable, or is stably self-propagated in the cytoplasm of a resting cell, and does not entail a change in DNA sequence.

The activation by an organism of the defense response of the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition.

The terminal region of a linear chromosome that includes the telomeric DNA repeats and associated proteins.

A conserved protein complex that catalyzes methylation of histone H3. In Saccharomyces the complex contains Shg1p, Sdc1p, Swd1p, Swd2p, Swd3p, Spp1p, Bre2p, and the trithorax-related Set1p; in mammals it contains the catalytic subunit (SETD1A or SETD1B), WDR5, WDR82, RBBP5, ASH2L/ASH2, CXXC1/CFP1, HCFC1 and DPY30.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
