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 a light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the chloroplast.

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 a cytokinin stimulus.

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 a gibberellin stimulus.

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

Any biological process in an organism that recurs with a regularity of approximately 24 hours.

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 absence of light stimuli.

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.

A series of molecular signals generated by the binding of a cytokinin to a receptor, and ending with regulation of a downstream cellular process, e.g. transcription.

A series of molecular signals mediated by the detection of gibberellic acid.

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

Any process that stops, prevents, or reduces the frequency, rate or extent of flower development.

Any process that stops, prevents, or reduces the frequency, rate or extent of gibberellic acid mediated signaling activity.

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

Expansion of the chloroplast that usually precedes division.

Any process that stops, prevents, or reduces the frequency, rate or extent of seed germination.

The process in which a change in the level of mono- and disaccharide glucose trigger the expression of genes controlling metabolic and developmental processes.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of chlorophyll, any compound of magnesium complexed in a porphyrin (tetrapyrrole) ring and which functions as a photosynthetic pigment, from less complex precursors.

Any process that modulates the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

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

The process whose specific outcome is the progression of the lateral root over time, from its formation to the mature structure. A lateral root is one formed from pericycle cells located on the xylem radius of the root, as opposed to the initiation of the main root from the embryo proper.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving nitrogen or nitrogenous compounds.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving nitrogen or nitrogenous compounds.

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

The process that occurs in a plant organ near the end of its active life that is associated with the dismantling of cell components and membranes, and an overall decline in metabolism.

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

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 a nitrogen compound stimulus.

Any process that activates or increases the frequency, rate or extent of chlorophyll biosynthetic process.

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

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.
