The content of amino acids involved in Lys metabolism in the seeds of different generations. a Total amino acid contents of brown rice in PA110 and wild-type PA64S in T2 generation in Hongkong, 2003. b Total amino acid contents of brown rice in PA110 and wild-type in T8 generation in Hangzhou, 2008. c Total amino acid contents of brown rice in PA110 and wild-type in T14 generation in Hangzhou, 2014. d The total amino acid content of PA110 and wild-type milling rice in the T14 generation. e The total amino acid content of PA110/9311 and PA64S/9311 brown rice in Hangzhou, 2014. f The free amino acid content of PA110 and wild-type brown rice in the T14 generation. Inserts indicate the total amount of all detectable amino acids. Gln and Asn were hydrolyzed to Glu and aspartate Asp under acidic conditions, and the final content of Glx was determined as the sum content of Gln and Glu; the final content of Asx was determined as the sum content of Asp and Asn. DW denotes dry weight. P values were generated by the two-tailed t test, and **P < 0.01 denotes statistical significance
