BIO353H5 Study Guide - Final Guide: Pericycle, Primordium, Cytokinin
Document Summary
Most probable way this will be presented on the exam: you"ll be given a list of genes and asked which is a receptor etc. Ck receptors are proteins that take the signal to the nucleus ahk. Response regulators then change what genes are doing and transfer the signal arr. It is a mass of semi-organised parenchyma cells derived from plant tissue (explants) for use in biological research and biotechnology. In plant biology, callus cells are those cells that cover a plant wound. Callus formation is induced from plant tissues after surface sterilization and plating onto in vitro tissue culture medium. Originates from cell layers in root and shoot expressing j0121. So it appears to come from the xylem-pole pericycle. It resembles lateral root primordia (lrp) regardless of where the explant"s origin is. If the plant can"t make lrp, it won"t make callus.
