The process of introducing a phosphate group on to a protein.

The process of introducing a phosphate group on to a protein.

An aging process that has as participant a cell after a cell has stopped dividing. Cell aging may occur when a cell has temporarily stopped dividing through cell cycle arrest (GO:0007050) or when a cell has permanently stopped dividing, in which case it is undergoing cellular senescence (GO:0090398). May precede cell death (GO:0008219) and succeed cell maturation (GO:0048469).

The process whose specific outcome is the progression of the embryo sac over time, from its formation to the mature structure. The process begins with the meiosis of the megasporocyte to form four haploid megaspores. Three of the megaspores disintegrate, and the fourth undergoes mitosis giving rise to a binucleate syncytial embryo sac. The two haploid nuclei migrate to the opposite poles of the embryo sac and then undergo two rounds of mitosis generating four haploid nuclei at each pole. One nucleus from each set of four migrates to the center of the cell. Cellularization occurs, resulting in an eight-nucleate seven-celled structure. This structure contains two synergid cells and an egg cell at the micropylar end, and three antipodal cells at the other end. A binucleate endosperm mother cell is formed at the center. The two polar nuclei fuse resulting in a mononucleate diploid endosperm mother cell. The three antipodal cells degenerate.

The process whose specific outcome is the progression of the pollen grain over time, from its formation to the mature structure. The process begins with the meiosis of the microsporocyte to form four haploid microspores. The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell. The pollen grain is surrounded by an elaborate cell wall. In some species, the generative cell immediately divides again to give a pair of sperm cells. In most flowering plants, however this division takes place later, in the tube that develops when a pollen grain germinates.

The process whose specific outcome is the progression of the organism over time, from the completion of embryonic development to the mature structure. See embryonic development.

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

The process that gives rise to secondary (or auxiliary or axillary) shoots in plants. This process pertains to the initial formation of a structure from unspecified parts. These secondary shoots originate from secondary meristems initiated in the axils of leaf primordia. Axillary meristems function like the shoot apical meristem of the primary shoot initating the development of lateral organs.

Any endogenous process that modulates the frequency, rate or extent of the plant hypersensitive response.

The modification of histone H3 by addition of one or more methyl groups to lysine at position 36 of the histone.

The chemical reactions and pathways involving carotenoids, tetraterpenoid compounds in which two units of 4 isoprenoid residues joined head-to-tail are themselves joined tail-to-tail.

The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.

The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.

Any process that activates or increases the frequency, rate or extent of the covalent addition of methyl groups to histones.

Any process that modulates the frequency, rate or extent of gene expression; the process is mitotically or meiotically heritable, or is stably self-propagated in the cytoplasm of a resting cell, and does not entail a change in DNA sequence.

Any process that modulates the frequency, rate or extent of programmed cell death, cell death resulting from activation of endogenous cellular processes.

Any process that stops, prevents, or reduces the frequency, rate or extent of multiplication or reproduction of fibroblast cells.

Any process that stops, prevents, or reduces the frequency, rate or extent of multiplication or reproduction of fibroblast cells.

The process whose specific outcome is the progression of the ovule over time, from its formation to the mature structure. The ovule is the structure in seed plants enclosing the female gametophyte, and is composed of the nucellus, one or two integuments, and the funiculus; it develops into the seed.

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

Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation.

Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation.

Any process in which a protein is maintained in the nucleus and prevented from moving elsewhere. These include sequestration within the nucleus, protein stabilization to prevent transport elsewhere and the active retrieval of proteins that escape the nucleus.

That part of the nuclear content other than the chromosomes or the nucleolus.

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.

That part of the nuclear content other than the chromosomes or the nucleolus.

A class of nuclear body; they react against SP100 auto-antibodies (PML, promyelocytic leukemia); cells typically contain 10-30 PML bodies per nucleus; alterations in the localization of PML bodies occurs after viral infection.
