title: Isoelectric focusing of cassava protoplasts.
abstract: Cassava (Manihot esculenta Crantz) protoplast was analyzed by using isoelectric focusing techniques. Two populations, representing 68 and 32% of the total sample, with mean isoelectric points of 4.48 and 4.60, were obtained using mesophyll protoplasts. The use of this technique allows demonstration of a discontinuous distribution of protoplast isoelectric point from one species according to their surface potential.
