Trama (mycology) Trama (mycology) In mycology, trama is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium. In essence, the trama is the tissue we call the "flesh" of mushrooms and similar fungi. Literally, "trama" is the Latin word for the "weft" or "woof" yarns in the weaving of cloth. This probably is related to the basidiocarp trama being "filler" tissue and that analogously the woof yarn in weaving is sometimes called "fill". Furthermore, the
Structural biology Structural biology Structural biology is a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules (especially proteins, made up of amino acids, and RNA or DNA, made up of nucleotides), how they acquire the structures they have, and how alterations in their structures affect their function. This subject is of great interest to biologists because macromolecules carry out most of the functions of cells, and it is only by coiling into specific three-dimensional shapes that they are able to perform these functions. This architecture, the "tertiary structure" of molecules, depends in a complicated way
