A cellular process in which two or more cells combine together, their plasma membrane fusing, producing a single cell. In some cases, nuclei fuse, producing a polyploid cell, while in other cases, nuclei remain separate, producing a syncytium.

Catalysis of the reaction: all-trans-violaxanthin = all-trans-neoxanthin.

The modification of histone H4 by the removal of an acetyl group from lysine at position 12 of the histone.

The modification of histone H4 by the removal of one or more acetyl groups.

The formation of a syncytium, a mass of cytoplasm containing several nuclei enclosed within a single plasma membrane, by one or more rounds of nuclear division without cytokinesis.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a silicon dioxide stimulus.

In organisms that undergo pheromone-induced unidirectional conjugation, the process involved in desensitization following exposure to pheromone stimulus that acts to down-regulate further stimulation or block initial conjugation responses.

The negative regulation of a signal transduction pathway in response to a stimulus upon prolonged exposure to that stimulus.

A protein complex that promotes the biogenesis of mitochondrial F1Fo-ATP synthase by facilitating assembly of the peripheral stalk. Loss of INAC function causes dissociation of the F1-domain from the membrane-integral Fo-portion.

OBSOLETE. The change in form (cell shape and size) that occurs during sexual reproduction in order to facilitate direct contact between the compatible mating types.

The asymmetric division of cells to produce two daughter cells with different developmental potentials. It is of fundamental significance for the generation of cell diversity.

The modification of histone H4 by the removal of an acetyl group from lysine at position 16 of the histone.

OBSOLETE. The change in form (cell shape and size) that contributes to sexual reproduction in order to facilitate direct contact between the compatible mating types in organisms that undergo pheromone-induced unidirectional conjugation.

The process in which a cell becomes capable of differentiating autonomously into a neuron in an environment that is neutral with respect to the developmental pathway. Upon specification, the cell fate can be reversed.

The lipid bilayer surrounding any of the thin, flattened compartments that form the medial portion of the Golgi complex.

The lipid bilayer surrounding any of the thin, flattened compartments that form the central portion of the Golgi complex.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a pheromone stimulus that regulates the process of pheromone-induced unidirectional conjugation.

The lipid bilayer surrounding any of the thin, flattened compartments that form the trans portion of the Golgi complex.

Unidirectional transfer of genetic information triggered by to a pheromone signal.

The process in which the developmental fate of a cell becomes restricted such that it will develop into a neuron.
