Visual cues are important for insects to find flowers and host plants. It has been proposed that the diversity of leaf shape in Passiflora vines could be a result of negative frequency dependent selection driven by visual searching behavior among their butterfly herbivores. Here we tested the hypothesis thatHeliconius butterflies use leaf shape as a cue to initiate approach toward a host plant....

Diabetes mellitus is the most common endocrine disorder that impairs glucose homeostasis resulting in severe diabetic complications including retinopathy, angiopathy, nephropathy, and neuropathy causing neurological disorders due to perturbation in utilization of glucose. Hypoglycemic activity was detected in aqueous extract of Passiflora ligularis, a traditionally used medicinal plant, using s...

In Present work, the main objective is to develop less time consuming protocol for genomic DNA isolation from leaves of Passiflora foetida. Optimized protocol is cost effective, as it avoided use of expensive liquid nitrogen. The important parameters of CTAB buffer composition such as Polyvinylpyrrolidone PVP40000 (without PVP, 1%, 2%, 3.5%, 4.0%, 4.5%, 5.0%), CTAB (w, 1%, 2%, 3%, 4%, 5%), wate...

Tendrils can be found in different plant species. In legumes such as pea, tendrils are modified leaves produced by the vegetative meristem but in the grape vine, a same meristem is used to either form a tendril or an inflorescence. Passiflora species originated in ecosystems in which there is dense vegetation and competition for light. Thus climbing on other plants in order to reach regions wit...

Mechanical site preparation methods that used tools mounted on lightweight excavators and provided localised intensive were tested in eight experimental sites across France where the vegetation was dominated either by (L.) Moench or Kuhn. Two (Deep Scarifier: DS; Deep Scarifier followed Multifunction Subsoiler: DS+MS) pine ( L., var. (Loudon) Hyl. Aiton) oak (Matt.) Liebl. L.) plantations...

Plants used in traditional medicine are rich sources of hemolysins and cytolysins, which are potential bactericidal and anticancer drugs. The present study demonstrates for the first time the presence of a hemolysin in the leaves of Passiflora quadrangularis L. This hemolysin is heat stable, resistant to trypsin treatment, has the capacity to froth, and acts very rapidly. The hemolysin activity...

Background Leaf shape among Passiflora species is spectacularly diverse. Underlying this diversity in leaf shape are profound changes in the patterning of the primary vasculature and laminar outgrowth. Each of these aspects of leaf morphology-vasculature and blade-provides different insights into leaf patterning. Results Here, we morphometrically analyze >3300 leaves from 40 different Passifl...

DNA barcoding is a technique for discriminating and identifying species using short, variable, and standardized DNA regions. Here, we tested for the first time the performance of plastid and nuclear regions as DNA barcodes in Passiflora. This genus is a largely variable, with more than 900 species of high ecological, commercial, and ornamental importance. We analyzed 1034 accessions of 222 spec...

BACKGROUND Many patients have preoperative anxiety; therefore, the development of a strong anxiolytic with minimal psychomotor impairment for premedication may be desirable. METHODS In this study, 60 patients were randomized into two groups to receive either oral Passiflora incarnata (500 mg, Passipy IranDarouk) (n = 30) or placebo (n = 30) as premedication, 90 min before surgery. A numerical...
