The chemical reactions and pathways resulting in the breakdown of pectin, a polymer containing a backbone of alpha-1,4-linked D-galacturonic acid residues.

The chemical reactions and pathways resulting in the breakdown of pectin, a polymer containing a backbone of alpha-1,4-linked D-galacturonic acid residues.

A cellular process that results in the breakdown of the cell wall that contributes to the process of abscission.

The dehiscence of an anther to release the pollen grains contained within it.

The process leading to the spontaneous opening of the fruit permitting the escape of seeds.

The chemical reactions and pathways resulting in the breakdown of pectin, a polymer containing a backbone of alpha-1,4-linked D-galacturonic acid residues.

A pattern of cell growth that occurs in conditions of nitrogen limitation and abundant fermentable carbon source. Cells become elongated, switch to a unipolar budding pattern, remain physically attached to each other, and invade the growth substrate.

The process whose specific outcome is the progression of the embryo over time, from zygote formation to the end of seed dormancy. An example of this process is found in Arabidopsis thaliana.

The process in which a cell irreversibly increases in size in one

A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of inextensible cellulose- and pectin-containing cell walls that are formed between the plasma membrane and primary cell wall after cell expansion is complete. An example of this is found in Arabidopsis thaliana.

The process whose specific outcome is the progression of the suspensor over time, from its formation to the mature structure. The suspensor is the extension at the base of the embryo that anchors the embryo in the embryo sac and pushes it into the endosperm.

The controlled shedding of floral organs.

The chemical reactions and pathways resulting in the breakdown of carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y.

The chemical reactions and pathways involving galacturonate, the anion of galacturonic acid, the uronic acid formally derived from galactose by oxidation of the hydroxymethylene group at C-6 to a carboxyl group.

The process in which a relatively unspecialized cell acquires specialized features of a haploid sperm cell within the plant gametophyte.

The process whose specific outcome is the progression of the root cap over time, from its formation to the mature structure. The root cap protects the root meristem from friction as the root grows through the soil. The cap is made up of a group of parenchyma cells which secrete a glycoprotein mucilage as a lubricant.

The chemical reactions and pathways involving pectin, a polymer containing a backbone of alpha-1,4-linked D-galacturonic acid residues, as part of the organization and biogenesis of the cell wall.

The radial pattern formation process that results in the formation of floral organ primordia around a central axis in a flower primordium.

The process in which the zygote irreversibly increases in size in one dimension after fertilization. An example of such a process is found in Arabidopsis thaliana.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

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.

The cell membranes and intracellular regions in a plant are connected through plasmodesmata, and plants may be described as having two major compartments: the living symplast and the non-living apoplast. The apoplast is external to the plasma membrane and includes cell walls, intercellular spaces and the lumen of dead structures such as xylem vessels. Water and solutes pass freely through it.

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; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins.

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

The component of a membrane consisting of the gene products that are tethered to the membrane only by a covalently attached anchor, such as a lipid group that is embedded in the membrane. Gene products with peptide sequences that are embedded in the membrane are excluded from this grouping.
