Transcript accumulation of genes potentially involved in ethylene and β-cyanoalanine biosynthesis in Populus trichocarpa. a Proposed biosynthetic pathway for β-cyanoalanine formation in poplar. ACS, 1-aminocyclopropane-1-carboxylic acid synthase; ACO, 1-aminocyclopropane-1-carboxylic acid oxidase; BCAS, β-cyanoalanine synthase. Gene expression of putative PtACS genes (b), PtACO genes (c), and PtBCAS genes (d) were measured using qRT-PCR in caterpillar-damaged (herb) and undamaged control (ctr) leaves of Populus trichocarpa. Transcript accumulation is shown as relative expression in comparison to ubiquitin. Asterisks indicate statistical significance in Student’s t-tests (p < 0.05). Means and SE are shown (n = 6 biological replicates). n.d., not detected
