Figure 6: Leaf growth is promoted in PATROL1-overexpressing plants.

(a–c) Plants grown under continuous light for 20 (a,b), and 34 days (c). (d–f) Plants grown under short-day conditions for 7 weeks (d,e) and further grown under continuous light for 2 weeks (f). (b,e) Fresh weight of aerial parts of the plants. Data are means±s.e.m.; n=21 (b) or n=10 (e). Statistical significance was analysed by ANOVA tests (20 days P=1.7 × 10⁻¹¹; 7 weeks P=1.17 × 10⁻⁴) followed by a post hoc Tukey test. Asterisks (*P<0.05, **P<0.005, ***P<0.001) indicate statistical significance. Scale bars=1 cm in (a) and (d), and 5 cm in (c) and (f).
