Identification of conjugated IAA in carrot crown gall as indole-3-acetylaspartic acid (IAAsp) by LC/MS






Journal of Plant Growth Regulation 13(4): 183-186

Identification of conjugated IAA in carrot crown gall as indole-3-acetylaspartic acid (IAAsp) by LC/MS

In carrot crown gall cells transformed with Ti plasmids, Ti-derived IAA biosynthetic genes are transcribed and translated, followed by overproduction of IAA. However, the newly synthesized IAA is immediately metabolized to IAA-amino acid conjugate, and the content of endogenous free IAA is maintained at a low level. In this study, IAA-amino acid conjugate in carrot tissues transformed with Ti plasmids was identified as indole-3-acetylaspartic acid (IAAsp) by using frit-fast atom bombardment liquid chromatography/mass spectrometry (LC/MS).
