Pharbinilic acid, an allogibberic acid from morning glory (Pharbitis nil).
Pharbinilic acid (1), the first naturally occurring allogibberic acid, was isolated from ethanol extracts of morning glory (Pharbitis nil) seeds. Its absolute configuration was determined by NOESY NMR and ECD experiments. Compound 1 showed weak cytotoxicity against A549, SK-OV-3, SK-MEL-2, and HCT-15 cells and weakly inhibited nitric oxide production in lipopolysaccharide-activated BV-2 microgl...
متن کاملDistribution of Three Auxin Protector Substances in Seeds and Shoots of the Japanese Morning Glory (Pharbitis nil).
The existence of substances which inhibit the enzymatic destruction of auxin in shoots of the Japanese morning glory (Pharbitis nil Choisy) has been confirmed, as has the fact that these substances are distributed in a gradient diminishing from apex to base in a manner indicating a regulatory role in internode elongation and tissue maturation. In addition to the 2 auxin protector substances rep...
متن کاملGenome sequence and analysis of the Japanese morning glory Ipomoea nil
Ipomoea is the largest genus in the family Convolvulaceae. Ipomoea nil (Japanese morning glory) has been utilized as a model plant to study the genetic basis of floricultural traits, with over 1,500 mutant lines. In the present study, we have utilized second- and third-generation-sequencing platforms, and have reported a draft genome of I. nil with a scaffold N50 of 2.88 Mb (contig N50 of 1.87 ...
متن کاملGibberellins in Relation to Growth and Flowering in Pharbitis nil Chois.
Flowering can be modified by gibberellins (GAs) in Pharbitis nil Chois. in a complex fashion depending on GA type, dosage, and the timing of treatment relative to a single inductive dark period. Promotion of flowering occurs when GAs are applied 11 to 17 hours before a single inductive dark period. When applied 24 hours later the same GA dosage is inhibitory. Thus, depending on their activity a...
