Abstract
Recently we reported the identification of the auxin-biosynthesis inhibitor, L-aminooxyphenylpropionic acid (AOPP), which blocks L-Tryptophan aminotransferase (PCP (2010) 51 (4): 524-536). We designed and synthesized novel AOPP analogues by modifying functional groups of AOPP and finally identified KOK1169 as more selectivity inhibitor than AOPP by several screening. Thus we examined the effect of KOK1169 treatment on auxin biosynthesis in Arabidopsis and Rice in vivo. The profile of endogenous auxin-biosynthesis related compounds will be reported. This work was supported by the Program for Promotion of Basic and Applied Researches for Innovations in Bio-oriented Industry (BRAIN).
