Relative Levels of Free Asp, Glu, Asn, and Gln in Wild-Type and Different Transgenic Arabidopsis Plants.
Relative levels of free Asp (A), Glu (B), Asn (C), and Gln (D) are given as mol % of total amino acids. DHPS/Ht and DHPS/Hm, transgenic plants expressing the phaseolin-DHPS construct in heterozygous and homozygous states, respectively; K/O, LKR/SDH knockout mutants; K/O × DHPS, LKR/SDH knockout × phaseolin-DHPS plants. Error bars represent standard errors.
