The chemical reactions and pathways involving brassinosteroids, any of a group of steroid derivatives that occur at very low concentrations in plant tissues and may have hormone-like effects.

Any process involved in the maintenance of an internal steady state of brassinosteroids within an organism or cell.

The chemical reactions and pathways resulting in the formation of saponins, glycosides of plants in which the aglycan (sapogenin) group is a terpene or steroid and the sugar group is a glucose, a galactose, a pentose, a methylpentose or an oligosaccharide. Saponins are powerful surfactant agents and membrane active; they are, hence, toxic to animals on injection.

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.

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 abscisic acid 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 brassinosteroid stimulus.

Any process involved in the maintenance of an internal steady state of brassinosteroids within an organism or cell.

The chemical reactions and pathways involving brassinosteroids, any of a group of steroid derivatives that occur at very low concentrations in plant tissues and may have hormone-like effects.

The chemical reactions and pathways resulting in the formation of trans-zeatin, (2E)-2-methyl-4-(9H-purin-6-ylamino)but-2-en-1-ol.

The chemical reactions and pathways resulting in the breakdown of 11-oxo-beta-amyrin.

The chemical reactions and pathways resulting in the formation of glycyrrhetinate.

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 a jasmonic acid 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 jasmonic acid stimulus.

The chemical reactions and pathways involving alkaloids, nitrogen containing natural products which are not otherwise classified as peptides, nonprotein amino acids, amines, cyanogenic glycosides, glucosinolates, cofactors, phytohormones or primary metabolites (such as purine or pyrimidine bases).

The chemical reactions and pathways involving an indole alkaloid, an alkaloid containing an indole skeleton.

The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).

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