Extended Data Fig. 8: Quantitative analysis of LM19 labeling suggest that there is no polar distribution of de-esterified HG in the stomata of fern and fava bean.

a, Quantitative analysis of LM19 labeling in fern GCs. n = 120 from 6 fern GCs, P < 1.00E-15. b, Quantitative analysis of LM19 labeling in fava bean. n = 100 from 5 fava beans, P < 1.00E-15. Statistical differences were determined by ANOVA with a post hoc Tukey test and indicated by different letters. The experiment was repeated twice independently.
