The chemical reactions and pathways involving the molybdopterin cofactor (Moco), essential for the catalytic activity of some enzymes, e.g. sulfite oxidase, xanthine dehydrogenase, and aldehyde oxidase. The cofactor consists of a mononuclear molybdenum (Mo-molybdopterin) or tungsten ion (W-molybdopterin) coordinated by one or two molybdopterin ligands.

The chemical reactions and pathways resulting in the formation of ommochromes, any of a large group of natural polycyclic pigments commonly found in the Arthropoda, particularly in the ommatidia of the compound eye.

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 solutes outside the organism or cell.

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 heat stimulus, a temperature stimulus above the optimal temperature for that organism.

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 cold stimulus, a temperature stimulus below the optimal temperature for that organism.

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 chemical reactions and pathways resulting in the formation of abscisic acid, 5-(1-hydroxy-2,6,6,trimethyl-4-oxocyclohex-2-en-1-y1)-3-methylpenta-2,4-dienoic acid.

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 of opening or closing of stomata, which is directly related to the stomatal conductance (measuring rate of passage of either water vapor or carbon dioxide (CO2) through stomata).

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 incorporation of molybdenum into a molybdenum-molybdopterin complex.

Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.

The targeting and import of proteins into the chloroplast stroma. Import depends on ATP hydrolysis catalyzed by stromal chaperones. Chloroplast stromal proteins, such as the S subunit of rubisco, have a N-terminal stromal-import sequence of about 44 amino acids which is cleaved from the protein precursor after import.
