The chemical reactions and pathways resulting in the formation of beta-glucans, compounds composed of glucose residues linked by beta-D-glucosidic bonds, found in the walls of cells.

The chemical reactions and pathways involving beta-glucans, compounds composed of glucose residues linked by beta-D-glucosidic bonds, found in the walls of cells.

The asymmetric cell division by which a meristemoid mother cells (MMC) give rise to a meristemoid and another cell. The other cell may itself become a MMC or may generate an epidermal cell. Any cell that undergoes this type of division is a MMC.

The process of dividing the cytoplasm of a parent cell where a structure forms in the cytoplasm and grows until reaching the plasma membrane, thereby completely separating the cytoplasms of adjacent progeny cells. An example of this is found in Arabidopsis thaliana.

The directed movement of a motile cell or organism in response to environmental oxygen.

The covalent alteration of one or more nucleotides within an RNA molecule to produce an RNA molecule with a sequence that differs from that coded genetically.

The covalent alteration of one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule, resulting in a change in its properties.

The process in which a meristemoid acquires the specialized features of a guard mother cell.

The process in which a relatively unspecialized cell acquires specialized features of a plant epidermal cell.

A small round nuclear body, measuring 0.2-0.8 microns in diameter that is diffusely distributed throughout the nucleoplasm. Several proteins known to be involved in miRNA processing have been localized to these structures. D-bodies are thought to be involved in primary-miRNA processing and/or storage/assembly of miRNA processing complexes.

The sequence of enzymatic reactions by which the 5' cap structure, an inverted 7-methylguanosine linked via a 5'-5' triphosphate bridge (m7G(5')ppp(5')X) to the first transcribed residue, is added to a nascent transcript.

The chemical reactions and pathways resulting in the formation of (1->3)-beta-D-glucans, compounds composed of glucose residues linked by (1->3)-beta-D-glucosidic bonds, found in the walls of ascospores.

The chemical reactions and pathways resulting in the formation of (1->3)-beta-D-glucans, compounds composed of glucose residues linked by (1->3)-beta-D-glucosidic bonds, found in fungal cell walls.

OBSOLETE. A group of small electron carriers, characteristic of anaerobic bacteria, photosynthetic bacteria, cyanobacteria and eukaryotic algae. Contain flavin mononucleotide.

Endonucleolytic cleavage of the 3'-end of the pre-tRNA as part of the process of generating the mature 3'-end of the tRNA.

Cleavage of the 3'-end of the pre-tRNA as part of the process of generating the mature 3'-end of the tRNA; may involve endonucleolytic or exonucleolytic cleavage, or both.

Any endonucleolytic RNA phosphodiester bond hydrolysis that is involved in tRNA processing.

OBSOLETE. A hemeprotein whose characteristic mode of action involves transfer of reducing equivalents associated with a reversible change in oxidation state of the prosthetic group. This redox change involves a single electron, reversible equilibrium between the Fe(II) and Fe(III) states of the central iron atom.
