GO Term : GO:0048758 companion cell differentiation GO

Namespace  biological_process Obsolete  false
Description  The process in which a relatively unspecialized cell acquires specialized features of a companion cell. The companion cell is the specialized parenchyma cell associated with a sieve-tube member in angiosperm phloem and arising from the same mother cell as the sieve-tube member.

GO:0009987 cellular process Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
GO:0008150 biological_process A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence.
GO:0032502 developmental process A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition.
GO:0048856 anatomical structure development The biological process whose specific outcome is the progression of an anatomical structure from an initial condition to its mature state. This process begins with the formation of the structure and ends with the mature structure, whatever form that may be including its natural destruction. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome.
GO:0048869 cellular developmental process A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition.
GO:0030154 cell differentiation The cellular developmental process in which a relatively unspecialized cell, e.g. embryonic or regenerative cell, acquires specialized structural and/or functional features that characterize a specific cell. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
GO:0009888 tissue development The process whose specific outcome is the progression of a tissue over time, from its formation to the mature structure.
GO:0010087 phloem or xylem histogenesis The process whose specific outcome is the progression of phloem and/or xylem over time, from formation to the mature structure. An example of this process is found in Arabidopsis thaliana.
GO:0010088 phloem development The formation of the principal food-conducting tissue of a vascular plant.
GO:0048760 plant parenchymal cell differentiation The process in which a relatively unspecialized cell acquires specialized features of a parenchymal cell. Parenchymal cells are the most abundant and versatile cells in plants. They have very few distinguishing characteristics and botanists classify them as any cell type that cannot be assigned to any other structural or functional class. They can redifferentiate and dedifferentiate and are involved in storage, basic metabolism and other processes. The cells are polyhedral, typically with thin, non-lignified cellulose cell walls and nucleate living protoplasm. They vary in size, form, and wall structure.
GO:0048758 companion cell differentiation The process in which a relatively unspecialized cell acquires specialized features of a companion cell. The companion cell is the specialized parenchyma cell associated with a sieve-tube member in angiosperm phloem and arising from the same mother cell as the sieve-tube member.
