Cell death resulting from activation of endogenous cellular processes, by a mechanism other than apoptosis.

The chemical reactions involving D-ribose (ribo-pentose). As beta-D-ribofuranose, D-ribose forms the glycose moiety of all ribonucleosides, ribonucleotides and ribonucleic acids, and also of ribose phosphates, various glycosides, some coenzymes and some forms of vitamin B12.

Interacting selectively with adenyl nucleotides, any compound consisting of adenosine esterified with (ortho)phosphate.

Any process that modulates the frequency, rate or extent of cellular defense response.

The directed movement of an antibiotic, a substance produced by or derived from certain fungi, bacteria, and other organisms, that can destroy or inhibit the growth of other microorganisms, into, out of, within or between cells.

Any process that activates or increases the rate of meiosis.

The process by which double-stranded RNAs silence cognate genes. Involves posttranscriptional gene inactivation ('silencing') both of transgenes or dsRNA introduced into a germline, and of the host gene(s) homologous to the transgenes or dsRNA. This silencing is triggered by the introduction of transgenes or double-stranded RNA (dsRNA), and occurs through a specific decrease in the level of mRNA of both host genes and transgenes.

Any process that activates or increases the rate or extent of color pattern formation in an organ or organism.

Any process that stops, prevents or reduces the rate of mitosis.

Any process that modulates the frequency, rate or extent of color pattern formation in an organ or organism.

The chemical reactions involving any amino sugar, sugars containing an amino group in place of a hydroxyl group.

Catalysis of the transfer of a methyl group from S-adenosylmethionine during the synthesis of quinone cofactors such as ubiquinone (coenzyme Q), menaquinone (vitamin K2), plastoquinone and phylloquinone (vitamin K1).

The chemical reactions involving a polyol, any polyhydric alcohol.

The chemical reactions involving glucosamine (2-amino-2-deoxyglucopyranose), an aminodeoxysugar that occurs in combined form in chitin.
