The chemical reactions and pathways involving biological pigments e.g. melanin, occurring as part of the development of an organ or organism.

The process whose specific outcome is the progression of the conidiophore over time, from its formation to the mature structure. The conidiophore is a specialized hypha that extends aerially from the growth substrate and bears conidia, or asexual spores.

The chemical reactions and pathways resulting in the breakdown of polyketides, any of a diverse group of natural products synthesized via linear poly-beta-ketones, which are themselves formed by repetitive head-to-tail addition of acetyl (or substituted acetyl) units indirectly derived from acetate (or a substituted acetate) by a mechanism similar to that for fatty acid biosynthesis but without the intermediate reductive steps.

The chemical reactions and pathways resulting in the formation of melanins, pigments largely of animal origin. High molecular weight polymers of indole quinone, they are irregular polymeric structures and are divided into three groups: allomelanins in the plant kingdom and eumelanins and phaeomelanins in the animal kingdom.

The chemical reactions and pathways resulting in the formation of a pigment, any general or particular coloring matter in living organisms, e.g. melanin.
