Stolon length of PHA1-OE plants grown in soil. (A) Stolon length of plants obtained from seed tubers, grown in soil, in a greenhouse, for 4 weeks. The data of four independent experiments (mean ±SE) are displayed in the bar graph; each experiment consisted of 3–4 soil-grown plants per condition, with 3–5 stolons per plant. The asterisks indicate statistical significance [*P<0.05, ****P<0.001, with respect to the wild type (wt)]. (B) Representative image of the underground part of the plants (upper panel) and detached stolons (lower panel).
