Abstract:
:A method for testing the purity of isolated vacuoles is proposed. Preparations of isolated vacuoles often contain "impure vacuoles," namely, vacuoles contaminated with some cytoplasmic remnants. Such impure vacuoles are stained by the vital fluorescent dye fluorescein-diacetate. Vacuoles enclosed only by the tonoplast, "naked vacuoles," do not stain.

PLANT PHYSIOLOGY文献大全abstract::A theory is presented to explain the phloem mobility of certain systemic xenobiotics that are not weak acids. It is shown that there is a theoretically optimum permeability that permits optimum circulation through the symplasm and apoplast (including the phloem and xylem) of Solanum tuberosum plants. The optimum perme...
