Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain.

The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.

The control of plant growth, development, and differentiation by the duration and nature of light, independent of photosynthesis.

A series of molecular signals mediated by the detection of a hormone.

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.

Any process that stops, reduces or prevents photomorphogenesis.

The process whose specific outcome is the progression of the fruit over time, from its formation to the mature structure. The fruit is a reproductive body of a seed plant.

The process in which a change in the level of a mono- or disaccharide such as glucose, fructose or sucrose triggers the expression of genes controlling metabolic and developmental processes.

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

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

A change from vegetative to reproductive phase as a result of detection of, or exposure to, a period of light that falls short of the critical day length. The critical day length varies between species. Although the term is short-day is used, most species actually respond to the duration of the night, so that the response will occur when a period of darkness exceeds the number of hours defined by 24 minus the critical day length.

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.

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.

A protein complex that includes a ubiquitin-protein ligase and enables ubiquitin protein ligase activity. The complex also contains other proteins that may confer substrate specificity on the complex.

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

A ubiquitin ligase complex in which a cullin from the Cul4 family and a RING domain protein form the catalytic core; substrate specificity is conferred by an adaptor protein.
