prootsesside
Prootsesside is a neologism used in theoretical discussions of plant root biology to denote a hypothetical class of signaling compounds associated with root processing and resource uptake. The term combines "roots" with a suffix implying a chemical or molecular role, and it is not an established chemical or biological entity in real-world science. In didactic and fictional contexts, prootsesside is described as a membrane-permeable or apoplastic signaling molecule produced in the root cap or epidermal tissues, transported toward the elongation zone, where it modulates cell division and differentiation of root tissues. Proponents use the concept to illustrate how signaling molecules could coordinate root growth, hormonal responses such as auxin or cytokinin signaling, and interactions with soil microbes.
Because prootsesside is not part of established plant physiology, there is no confirmed structure, biosynthetic pathway,
Overall, prootsesside functions as a conceptual tool rather than an empirically defined substance, helping to frame
