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 stimulus from a virus.

The process in which the structures of a hair cell (trichome) cell are generated and organized. This process occurs while the initially relatively unspecialized epidermal cell is acquiring the specialized features of a hair cell. An example of this process is found in Arabidopsis thaliana.

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

Any process that modulates the frequency, rate or extent of cyclin-dependent protein serine/threonine kinase activity.

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

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 stimulus indicating an increase or decrease in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment.

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 modulates the rate or extent of the viral life cycle, the set of processes by which a virus reproduces and spreads among hosts.

Any process that modulates the rate or extent of progression through the cell cycle.

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.

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

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

Any protein complex that interacts with RNA polymerase II to increase (positive transcription elongation factor) or reduce (negative transcription elongation factor) the rate of transcription elongation.

A fine cytoplasmic channel, found in all higher plants, that connects the cytoplasm of one cell to that of an adjacent cell.

A discrete extra-nucleolar subnuclear domain, 20-50 in number, in which splicing factors are seen to be localized by immunofluorescence microscopy.

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.
