Shown values are the means and standard errors of 10 replicate pots (shoot material was pooled from each pot). WT, wild-type Indian mustard; APS, adenosine triphosphate sulfurylase–overexpressing Indian mustard; GS, glutathione synthetase–overexpressing Indian mustard; -ECS, -glutamylcysteine synthetase–overexpressing Indian mustard. The letters above the bars indicate statistically significant groups (t test, compairing each pair, = 0.05).
