DOI: 10.1104/pp.17.00222
Abstract: The immune regulator pipecolic acid is synthesized by ALD1-mediated conversion of l-Lys to 2,3-dehydropipecolic acid and consecutive reduction, to which Arabidopsis SARD4/ORNCD1 largely contributes. The nonprotein amino acid pipecolic acid (Pip) regulates plant systemic acquired… read more here.
