Superscript ‘a’ indicates significant difference from wild-type at P ≤ 0.05. Superscript ‘b’ indicates significant difference between the two transgenic lines at P ≤ 0.05. Values are ± standard deviation. CyA, cysteic acid (hydrolysis product of cysteine); Asp, Asp+Asn (due to hydrolysis of Asn to Asp); Glu, Glu+Gln (due to hydrolysis of Gln to Glu).
