highly significantP = 0.0002
A pairwise combined microCT and gas exchange analysis of the four Arabidopsis lines revealed a highly significant positive correlation of g s and palisade porosity (Pearson correlation, r 2 = 0.471, P = 0.0002; Fig. 5l ), with the focl-1 mutant data grouping below those for the Col-0 control and on a par with the EPF2OE samples.
