Abstract/OtherAbstract:
|
The aim of this study was to reveal the pyridine metabolism in leaves of two mangrove legumes, Derris indica (= Millettia pinnata or Pongamia pinnata) and Caesalpinia crista. Radioactivity from [carbonyl-14C]nicotinamide supplied exogenously to young leaf disks was recovered in nicotinic acid, nicotinic acid mononucleotide, NAD, NADP, nicotinamide mononucleotide and trigonelline. These mangrove species, especially D. indica, have strong ability to convert nicotinamide to trigonelline, but not to nicotinic acid glucoside. The endogenous trigonelline content in leaves of D. indica was more than 830 microg/g dry weight. This value is 5-12 times greater than that in leaves of Glycine max. There was little short-term effect of 250 and 500 mM NaCl (equivalent to ca. 50% and 100% sea water) on nicotinamide metabolism. |
