Extended Data Fig. 2. Roots of tomato wild relative Solanum pennellii (LA0716) contain significantly more suberin than Solanum lycopersicum (cv. M82).

(a) Mean monomer abundance and (b) total suberin expressed as μg mg⁻¹ of total dry weight. n = 5, error bars: SD. Asterisks indicate significance with one-way ANOVA followed by a Tukey-Kramer post hoc test: P: ‘***’ <0.001 ‘**’ <0.01, n.s.: ‘not significant’. Acid: fatty acids; Alcohols: primary alcohols; ω-OH: ω-hydroxy fatty acids; DCA: dicarboxylic fatty acid; Aromatics: ferulate and coumarate derivatives.
