Stable expression of PITG_15718.2 inhibits the vegetative growth of S. tuberosum. (a) Images of transgenic lines and controls. Each transgenic line was planted in one tissue-cultural container with Désirée. Three seedlings on each side, forming a confrontation. Images were photographed two weeks after planting; (b) the plant height was significantly dwarfed for each transgenic potato line compared to Désirée. The plant height was measured in at least 30 plantlets. ** indicates extremely significant differences determined using the Student’s t-test (p < 0.01); (c) the transgenic lines show stunted phenotype after planting in soil. Image was photographed three weeks after planting into soil. The plant height was measured in at least 20 plantlets. ** indicates extremely significant differences determined using the Student’s t-test (p < 0.01).
