Previous study reported a novel type of self-discrimination in the tendrils of the vine Cayratia japonica (Vitaceae). However, whether self-discrimination in tendrils is common in vine plant species has not been elucidated. Here, we investigated whether tendrils of Momordica charantia var. pavel (Cucurbitaceae), Cucumis sativus (Cucurbitaceae) and Passiflora caerulea (Passifloraceae) can discriminate self and non-self plants. We also investigated whether the tendrils of M. charantia and C. sativus can discriminate differences in cultivars to determine the discrimination ability for genetic similarity...

Chronic progressive diseases of the central nervous system such as granulomatous amoebic encephalitis, amoebic keratitis, amoebic pneumonitis and also skin infections caused by free-living amoebae (Acanhamoeba spp.) are a significant challenge for pharmacotherapy. This is due to the lack of effective treatment because of encystation, which makes the amoebae highly resistant to anti-amoebic drugs. A very inter- esting and promising source of future drugs in this area are plant materials obtained not only from the habitat but also from plant in vitro culture as an alternative source of biomaterials...

Passiflora incarnata is marketed in many countries as anxiolytic herbal supplement. Herbal medicines are natural products, but it doesn't mean they are always safe, especially during pregnancy. Passiflora incarnata extract was not teratogenic in experimental studies. However, there are no data available on possible effects on human pregnancy. Here we report five pregnant women with depression and/or anxiety who used passiflora incarnata in pregnancy. We observed one pregnancy resulting in neonatal death, two pregnancies with premature rupture of membranes, two infants with meconium aspiration syndrome and one infant with persistent pulmonary hypertension...

The aim of this study was to investigate the sedative activity of the aqueous leaf extract of Passiflora quadrangularis, a species that is widely cultivated and consumed in South America, and to identify its main constituents and elucidate the involvement of the GABAergic pathway in its mechanism of action. The bioguided fractionation of the crude extract showed a positive relationship between the sedative activity of the extract and its flavonoids. The methods employed to identify and isolate its main flavonoids resulted in the identification of vitexin-2''-O-xyloside, vitexin-2''-O-glucoside, orientin-2''-O-xyloside and orientin-2''-O-glucoside...

Intercellular CO2 concentration of leaves (ci) is a critical parameter in photosynthesis. Nevertheless, uncertainties in calculating ci (ci(c)) arise as stomata close. Here, applying a system for directly measuring ci (ci(m)) to a commercial gas-exchange equipment, we demonstrate overestimation of ci(c) without stimulating stomatal closure. Gas-exchange was measured on one leaf side while ci(m) was acquired simultaneously on the other side in hypostomatous passionfruit (Passiflora edulis Sims), and amphistomatous sunflower (Helianthus annuus L...

Rapid biosynthesis of abscisic acid (ABA) in the leaf, triggered by a decrease in cell volume, is essential for a functional stomatal response to vapour pressure deficit (VPD) in angiosperms. However, it is not known whether rapid biosynthesis of ABA is triggered in other plant tissues as well. Through the application of external pressure to flower, root and leaf tissues, we test whether a reduction in cell volume can trigger rapid increases in ABA levels across plant body in two species Solanum lycopersicum and Passiflora tarminiana...
