In vitro and ex vitro grown patatin hpRNAi lines display normal growth phenotype. (A) Wild-type and patatin hpRNAi lines grown in vitro. In vitro grown potato plants were cultivated at 24 ± 2°C for 4 weeks and then tuberization was induced at 20 ± 2°C for 4 weeks. WT and patatin hpRNAi lines produced round pink micro-tubers in various sizes in vitro. (B) Potato tubers of patatin hpRNAi lines and WT plants grown in a greenhouse for 14 weeks. (C) The number of potato tubers per plant and average tuber weight in WT and patatin hpRNAi lines grown in greenhouse. Lanes 1 to 10 are patatin hpRNAi potato lines. Mean and SD were derived by measurement of five plants per line. The error bars indicate mean ± SD. There were no significant difference in the mean values between WT and patatin hpRNAi lines, when assessed with Anova's t-test at P < 0.01, respectively. (D) Patatin hpRNAi lines and WT plants grown in greenhouse for 8 weeks. There were no phenotypic differences between WT and patatin hpRNAi lines.
