The directed movement of cytosine, 4-amino-2-hydroxypyrimidine, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The process in which a purine-containing compound is transported across a membrane. A purine-containing compound is any compound that contains purine or a formal derivative thereof.

The directed movement of purine bases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of cytosine, 4-amino-2-hydroxypyrimidine, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

A process that reduces or removes the toxicity of a xenobiotic by exporting it outside the cell.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of nourishment.

The directed movement of cytidine, cytosine riboside, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of cytidine, cytosine riboside, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

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

The process in which a group of unicellular organisms grow in a threadlike, filamentous shape in response to deprivation of nourishment.

The process in which a group of unicellular organisms grow in a threadlike, filamentous shape in response to a biotic (living) stimulus.

The process in which a purine-containing compound is transported across a membrane. A purine-containing compound is any compound that contains purine or a formal derivative thereof.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures.

A vacuole that has both lytic and storage functions. The fungal vacuole is a large, membrane-bounded organelle that functions as a reservoir for the storage of small molecules (including polyphosphate, amino acids, several divalent cations (e.g. calcium), other ions, and other small molecules) as well as being the primary compartment for degradation. It is an acidic compartment, containing an ensemble of acid hydrolases. At least in S. cerevisiae, there are indications that the morphology of the vacuole is variable and correlated with the cell cycle, with logarithmically growing cells having a multilobed, reticulated vacuole, while stationary phase cells contain a single large structure.

The lipid bilayer surrounding a vacuole, the shape of which correlates with cell cycle phase. The membrane separates its contents from the cytoplasm of the cell. An example of this structure is found in Saccharomyces cerevisiae.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
