title: A simple technique for obtaining functionally isolated guard cells in epidermal strips of Vicia faba.
abstract: Ultrasonic irradiation of Vicia faba L. epidermal strips for 2 min preferentially disrupts the epidermal cells but does not impair guard cell movements. Maximal opening induced by fusicoccin requires that K(+) be provided to the guard cells from external sources. A mobile organic anion is not required.
