Determination of ploidy level and genome size in Dioscorea rotundata plant TDr96_F1. a TDr96_F1 plant grown in a greenhouse at Iwate Biotechnology Research Center (IBRC), Japan. Bar = 50 cm. b TDr96_F1 tuber. Bar = 10 cm. c Diploid somatic chromosomes at metaphase stage obtained from TDr96_F1 root tips (2n = 2× = 40). d FCM histogram of propidium iodide (PI)-stained nuclei from D. rotundata (TDr96_F1) and rice (Oryza sativa L.). Rice (genome size = 380 Mb) served as an internal reference standard. 1 = G1 (O. sativa), 2 = G1 (D. rotundata), and 3 = G2 (D. rotundata), where G1 and G2 represent the Gap 1 and Gap 2 phases of the cell cycle, respectively
