A.  aIsoeletric focusing of cassava protoplasts  c1991  aCassava (Manihot  esculenta Crantz) protoplast was analyzed by using isoleletric focusing technique. Two populations, representing 68 and 32% of the total sample, with means isoeletric points of 4.48 and 4.60, were obtained using mesophyl protoplast. The use  of this technique allows demonstration of a discontinuos distribuition of protoplast isoeletric point from one species according to their surface potential.1 aVILLEGAS, L.  tPlant Physiol.gv.95, p.335-336, 1991.
