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.

Identifier Name Description
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:0030154 cell differentiation The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
GO:0044699 single-organism process A biological process that involves only one organism.
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 Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
GO:0044763 single-organism cellular process Any process that is carried out at the cellular level, occurring within a single organism.
GO:0044767 single-organism 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, involving only one organism.
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: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: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.
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.
