The specification of the site where a daughter cell will form, in organisms that reproduce by budding. An example of this process is found in Saccharomyces cerevisiae.

A conjugation process that results in the union of cellular and genetic information from compatible mating types. An example of this process is found in Saccharomyces cerevisiae.

The developmental process in which the size or shape of a cell is generated and organized.

Any process involved in the progression from anaphase/telophase to G1 that is associated with a conversion from high to low mitotic CDK activity.

Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals.

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

The specification and formation of anisotropic intracellular organization or cell growth patterns.

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

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

Control of the formation, spatial distribution, and breakdown of the septin ring.

Any process that increases the rate or frequency of conjugation with cellular fusion.

The series of molecular signals that bring about the relay, amplification or dampening of a signal generated in response to a cue, such as starvation or pheromone exposure, in organisms that undergo conjugation with cellular fusion.

A series of molecular signals within the cell that are mediated by the Cdc42 protein switching to a GTP-bound active state.

Any process that modulates the frequency, rate or extent of the cell cycle process in which the distance is lengthened between poles of the spindle.

Any process that modulates the frequency, rate or extent of barrier septum formation. Barrier septum formation is the assembly and arrangement of a septum that spans the plasma membrane interface between progeny cells following cytokinesis.

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 cell switches from growing as a round budding cell to growing as a filament (elongated cells attached end-to-end). An example of this is the yeast-hyphal transition of Candida albicans.

A process in which a protein is transported to, or maintained in, the cell cortex.

Any process that activates or increases the frequency, rate or extent of filamentous growth of a population of unicellular organisms in response to biotic stimulus.

Any process that modulates the frequency, rate or extent of establishment or maintenance of cell polarity regulating cell shape.

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.

The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth.

The portion of the budding yeast plasma membrane where a daughter cell will emerge. The yeast marks this spot with bud-site selection proteins before bud emergence occurs. Actin is polarized to this spot just prior to and during bud emergence.

The end, or tip, of a fungal hypha, where polarized growth occurs during hyphal elongation.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The end of a cellular bud distal to the site of attachment to the mother cell.

The constriction between the mother cell and daughter cell (bud) in an organism that reproduces by budding.

Any part of a cell where non-isotropic growth takes place.

The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. In Eukaryotes, the cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane, and the mitotic, or meiotic, spindle is aligned perpendicular to the division plane. In bacteria, the cell division site is generally located at mid-cell and is the site at which the cytoskeletal structure, the Z-ring, assembles.

The region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell.

The region at the end of the longest axis of a cylindrical or elongated cell.

A protein complex formed by the association of the small GTPase Cdc42 with additional proteins. In Schizosaccharomyces the complex contains the Cdc42, Ras1, Scd1, Scd2, andShk1 proteins, and functions in the Ras1-Scd GTPase signalling pathway.

A spindle that forms as part of mitosis. Mitotic and meiotic spindles contain distinctive complements of proteins associated with microtubules.

A region of the cell cortex that contains a higher concentration of growth polarity factors than the surrounding cortex and that changes position over time. An example is found in fission yeast cells during early mating, in which the GTPase Cdc42 dynamically to discrete zones within the cortex prior to shmoo formation.

Any cell cortex that is part of a growing cell tip.
