Both rewards and signals are important in mutualisms. In myrmecochory, or seed dispersal by ants, the benefits to plants are relatively well studied, but less is known about why ants pick up and move seeds. We examined seed dispersal by the ant Aphaenogaster rudis of four co-occurring species of plants, and tested whether morphology, chemical signaling, or the nutritional quality of fatty seed ...

Viburnum grandiflorum Wall. ex DC., is a plant of Himalaya and Hazara region of Pakistan which was screened for bioactive secondary metabolite and screen for biological activity. Preliminary phytochemical profiling indicated the presence of different classes of secondary plant metabolites such as alkaloids, terpenoids, saponins, anthraquinone. These secondary metabolites vary in types in differ...

Abstract Low temperature plasma (LTP) exerted beneficial effects on seed germination and crop growth. With application of LTP Platycodon grandiflorum , indexes physiological parameters transcriptome profile were investigated in this experiment. The results showed the rate germinating potential increased by 24.7% 30.7% comparing to CK respectively ( p < 0.05). SOD CAT activity sprouts 26.78% ...

Micropropagation is an effective way to preserve the gene pool of threatened plants. This study devoted mathematical modeling nutrient media and effect mT (meta-topoline) on multiplication shoots Hedysarum grandiflorum, Hyssopus cretaceus, Matthiola fragrans in vitro comparison with benzylaminopurine (BAP) kinetin (KT). Initiation was performed MS medium 0.5 mg/L BAP. For multiplication, MS, B5...

A genuine triterpenoid saponin, platyconic acid A (1) was isolated from the roots extract of Platycodon grandiflorum, together with five known saponins: deapioplatycoside E (2), platycoside E (3), platycodin D(3) (4), platycodin D(2) (5) and platycodin D (6). The structure of 1 was determined on the basis of spectral analysis and chemical evidence.
