The process that gives rise to a lateral root. This process pertains to the initial formation of a structure from unspecified parts. A lateral root primordium represents an organized group of cells derived from the root pericycle that will differentiate into a new root, as opposed to the initiation of the main root from the embryo proper.

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 an auxin stimulus.

The process whose specific outcome is the progression of the flower over time, from its formation to the mature structure. The flower is the reproductive structure in a plant, and its development begins with the transition of the vegetative or inflorescence meristem into a floral meristem.

The establishment, maintenance and elaboration of the adaxial / abaxial axis. Adaxial refers to being situated toward an axis of an anatomical structure. Abaxial refers to being situated away from an axis of an anatomical structure.

The establishment, maintenance and elaboration of the centrolateral axis. In plants, this axis is duplicated and runs from the midrib to the margin of the leaf.

The process in which an organism retains a population of root meristem cells, preventing the commitment of all stem cell progeny to a differentiated cell fate.

Any process that modulates the frequency, rate or extent of the physical partitioning and separation of an epidermal cell into daughter cells. An epidermal cell is any of the cells that make up the epidermis.

The process whose specific outcome is the progression of the stipule over time, from its formation to the mature structure. A stipule is one of (usually) a pair of appendages at the bases of leaves in many broad-leaved angiosperms.

A developmental process that results in the initiation of an axillary shoot meristem. An axillary shoot meristem is a shoot meristem formed in the axil of a leaf.

Development of a plant organ, a multi-tissue plant structure that forms a functional unit.

Any process that activates or increases the frequency, rate or extent of stem cell population maintenance.

Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.

The process whose specific outcome is the progression of the embryo over time, from zygote formation to the end of seed dormancy. An example of this process is found in Arabidopsis thaliana.

The process by which an organism or tissue maintains a population of stem cells of a single type. This can be achieved by a number of mechanisms: stem cell asymmetric division maintains stem cell numbers; stem cell symmetric division increases them; maintenance of a stem cell niche maintains the conditions for commitment to the stem cell fate for some types of stem cell; stem cells may arise de novo from other cell types.

The process whose specific outcome is the progression of the anther over time, from its formation to the mature structure.

The process whose specific outcome is the progression of adventitious root over time, from its formation to the mature structure. Adventitious roots are post-embryonic roots that develop from the plant shoot.

The process whose specific outcome is the progression of the stomium over time, from its formation to the mature structure. A stomium is a fissure or pore in the anther lobe through which the pollen is released.

Any process that activates or increases the rate or extent of cell proliferation.

Any process that activates or increases the rate or extent of cell proliferation.

A series of molecular signals generated by the binding of the plant hormone auxin to a receptor, and ending with modulation of a downstream cellular process, e.g. transcription.

The process whose specific outcome is the progression of the embryo over time, from zygote formation to the end of seed dormancy. An example of this process is found in Arabidopsis thaliana.

The specification of the meristem which will give rise to all post-embryonic above-ground structures of the plant as well as the non-root below-ground structures, such as rhizomes and tubers.

Any process involved in maintaining the size and shape of a meristem.

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.

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

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

The process whose specific outcome is the progression of the cotyledon over time, from its formation to the mature structure. The cotyledon is the modified leaf (seed leaf), found as part of the embryo in plant seeds. It is involved in either storage or absorption of food reserves. Dicotyledonous seeds contain two cotyledons, while monocotyledonous seeds contain only one. The cotyledons may appear above ground and show photosynthetic activity in the seedling.

The process whose specific outcome is the progression of adventitious root over time, from its formation to the mature structure. Adventitious roots are post-embryonic roots that develop from the plant shoot.

The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.

The process in which boundaries between a cotyledon and the surrounding tissue are established and maintained.

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.

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