“…SOME RHIZOSPHERE MICROORGANISMS secrete exoenzymes that can induce pathological conditions in plant roots (Jones, 1909;Ulrich and McLaren, 1971 ) . Not all proteins taken up by roots are enzymes, and nonenzymatic proteins can influence root growth and cell function.…”

“…Not all proteins taken up by roots are enzymes, and nonenzymatic proteins can influence root growth and cell function. Lysozyme (as a protein; there is no known substrate for this enzyme in roots) has been found to inhibit root growth and has minimal nutritional value as a nitrogen source (Ulrich, Luse, and McLaren, 1964) . Uptake of basic proteins by plant roots has been studied with barley, onion, tomato, and vetch (Seear, Bradfute, and McLaren, 1968).…”

A basic protein, lysozyme, labeled with fluorescein isothiocyanate, is readily taken up by roots of lasione montana. Most of the protein taken up is tightly bound to cell walls of the roots. Fluorescent protein is diluted in the growing region of a root as cells elongate and divide. Fluorescence remains in mature nongrowing regions and root cap cells for one to two weeks. Redistribution and translocation of the protein within the root is minimal or nil. A layer of chloroform‐soluble material that prevents lysozyme from interacting with stem cell walls exposed to fluorescent lysozyme was found on stems of germinating Iasione montana.
