Trama (mycology) trama tends to be soft tissue, and in weaving, the woof yarn is not tightly stretched; it therefore need not as a rule be as strong as the warp yarn. 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
Mathematical and theoretical biology is concerned with the study of general, relational models of complex biological systems, usually abstracting out specific morphological, or anatomical, structures. Some of the simplest models in ARB are the Metabolic-Replication, or (M,R)--systems introduced by Robert Rosen in 1957-1958 as abstract, relational models of cellular and organismal organization. Other approaches include the notion of autopoiesis developed by Maturana and Varela, Kauffman's Work-Constraints cycles, and more recently the notion of closure of constraints. Algebraic biology (also known as symbolic systems biology) applies the algebraic methods of symbolic computation to the study of biological problems, especially in genomics, proteomics, analysis of molecular
