Fig. 2.

Shoot and root growth in grafts of wild-type and the patrol1 mutant. a Reciprocal micrografting using wild-type (WT) and patrol1 knockout mutant (KO) was performed. Images of grafted plants at 14 days after grafting are shown. Scale bar indicates 2 cm. b,c Shoot fresh weight was measured for intact WT and KO (b) and each graft combination (c) (n = 10–18). An asterisk indicates statistical significance (Student’s t-test, P < 0.05). Differences between the sample groups were tested using two-way ANOVA followed by a Tukey–Kramer HSD (between b and c, P < 0.05; other combinations, P < 0.01)
