CC

extracellular region

A location, relative to cellular compartments and structures, occupied by a macromolecular machine when it carries out a molecular function. There are two ways in which the gene ontology describes locations of gene products: (1) relative to cellular struc

CC

cell wall

The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; i

BP

defense response

Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.

BP

signal transduction

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or f

CC

plant-type cell wall

A more or less rigid stucture lying outside the cell membrane of a cell and composed of cellulose and pectin and other organic and inorganic substances.

GO:0009506

CC

plasmodesma

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

GO:0016020

CC

membrane

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

GO:0090353

MF

polygalacturonase inhibitor activity

Stops, prevents or reduces the activity of a polygalacturonase. Polygalacturonases catalyze the random hydrolysis of 1,4-alpha-D-galactosiduronic linkages in pectate and other galacturonans.
