Changes in trigonelline (N-methylnicotinic acid) content and nicotinic acid metabolism during germination of mungbean (Phaseolus aureus) seeds.
Changes in trigonelline content and in biosynthetic activity were determined in the cotyledons and embryonic axes of etiolated mungbean (Phaseolus aureus) seedlings during germination. Accumulation of trigonelline (c. 240 nmol per pair of cotyledons) was observed in the cotyledons of dry seeds; trigonelline content decreased 2 d after imbibition. Trigonelline content in the embryonic axes incre...
متن کاملChanges of Trigonelline, Nicotinic Acid and Proline Content in Early Growth Stages of Trigonella foenum-graecum L. under Saline Condition
Background: Some health-protecting secondary metabolites can be found at a higher concentration in the sprouts compared to other stages of plant growth. In addition, environmental stresses such as salt stress may be resulting in the increase or decrease of specific secondary metabolites in sprouts and plants. Objective: Evaluation the changes of trigonelline, nicotinic acid, and proline cont...
متن کاملHomarine (N-methylpicolinic acid) and trigonelline (N-methylnicotinic acid) appear to be involved in pattern control in a marine hydroid.
A morphogenetically active compound has been isolated from tissue extract of Hydractinia echinata and identified to be N-methylpicolinic acid (homarine). When applied to whole animals, homarine prevents metamorphosis from larval to adult stage and alters the pattern of adult structures. The concentration of homarine in oocytes is about 25 mM. During embryogenesis, metamorphosis and early colony...
متن کاملMetabolism of trigonelline.
During the germination of seeds and the early growth of plants, trigonelline (N-methylnicotinic acid) disappears and pyridine nucleotides appear in the plant tissue (1, 2). Hence, it has been surmised, albeit without direct evidence, that the trigonelline of the seeds is a precursor of pyridine nucleotides in seedling plants. In an earlier study from this laboratory (3), it was shown that prepa...
