Fig. 2From: Protoplast isolation prior to flow cytometry reveals clear patterns of endoreduplication in potato tubers, related species, and some starchy root cropsExample of flow cytometry histogram obtained from protoplast preparation of Solanum tuberosum cv. Superior tuber cortex (a) and pith (b) showing relative abundance of nuclei with differing DNA contents. Note the separation between peaks allowing for reliable frequency estimationsBack to article page
