Recently, it has been suggested that internal transcribed spacer (ITS) sequences are under selective constraints to preserve their secondary structure. Here, we investigate the patterns of the ITS nucleotide and secondary structure conservation across the Passiflora L. genus to evaluate the potential use of secondary structure data as a helpful tool for the alignment in taxonomically complex genera. Considering the frequent use of ITS, this study also presents a perspective on future analyses in other plant groups...

The hepatoprotective effect of P. leschenaultii. (DC) leaves was investigated in rats under paracetamol induced oxidative stress. Leaf acetone extract (200 and 400mg/kg) were administered daily via gavage for 14days before paracetamol (2000mg/kg, p.o.) treatment. After the experiment, the levels of serum biochemical parameters and enzymatic antioxidant levels were determined. Furthermore, liver tissues were analyzed histopathologically. Additionally, the molecular docking studies of the identified compounds against PXR and FXR proteins were also performed...

Skin aging is a complex process that is strongly affected by UV radiation, which stimulates the production of reactive oxygen species (ROS) in the epidermis and dermis and subsequently causes skin damage. Among the major consequences are increased collagen degradation and reduced collagen synthesis. Previous reports have demonstrated the beneficial effects of polyphenols for healthy skin. Passiflora tarminiana Coppens & V.E. Barney, a species of the Passifloraceae family, is widely distributed in South America and is rich in flavonoids...

Peter Giovannini, Melanie-Jayne R Howes
ETHNOPHARMACOLOGICAL RELEVANCE: Every year between 1.2 and 5.5 million people worldwide are victims of snakebites, with about 400,000 left permanently injured. In Central America an estimated 5,500 snakebite cases are reported by health centres, but this is likely to be an underestimate due to unreported cases in rural regions. The aim of this study is to review the medicinal plants used traditionally to treat snakebites in seven Central American countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama...

BACKGROUND: Passiflora (passionflowers) makes an excellent model for studying plant evolutionary development. They are mostly perennial climbers that display axillary tendrils, which are believed to be modifications of the inflorescence. Passionflowers are also recognized by their unique flower features, such as the extra whorls of floral organs composed of corona filaments and membranes enclosing the nectary. Although some work on Passiflora organ ontogeny has been done, the developmental identity of both Passiflora tendrils and the corona is still controversial...

OBJECTIVE: In this study, we have evaluated the skeletal effects of butanolic fraction (BF) from Passiflora foetida in an estrogen deficient mice bone loss model. STUDY DESIGN: Skeletal effect of BF was studied in ovariectomized (OVx) female Balb/c mice. BF (50 and 100mg/kg/day dose orally) was given for 8 weeks. Micro-architecture of long bones, biomechanical strength, formations of mineralized nodule by bone marrow osteoprogenitor cells, osteoid formation and bone turnover markers were studied...

Passiflora mollissima (Kunth) L.H. Bailey is an exotic fruit native to South America, known as taxo in Ecuador. This paper characterizes its flavonoid and carotenoid composition and antioxidant capacity and evaluates the effect of the spray-drying process on its phytochemical composition and antioxidant capacity. A total of 18 flavonoid compounds, nine proanthocyanidins and nine flavan-3-ol monomers, were identified and quantified. Glycosides of (epi)-afzelechin stood out as the most abundant flavonoid. Three carotenoids were identified, with β-carotene having the highest concentration...

A hydroxynitrile lyase from the passion fruit Passiflora edulis (PeHNL) was isolated from the leaves and showed high stability in biphasic co-organic solvent systems for cyanohydrin synthesis. Cyanohydrins are important building blocks for the production of fine chemicals and pharmaceuticals. Thus, to enhance production yields of PeHNL for industrial applications, we cloned and expressed recombinant PeHNL in Escherichia coli BL21(DE3) and Pichia pastoris GS115 cells without a signal peptide sequence. The aim of this study is to determine the effect of N-glycosylation on enzyme stability and catalytic properties in microbial expression systems...

The complete genome sequence of a bipartite begomovirus (genus Begomovirus, family Geminiviridae) infecting yellow passion fruit (Passiflora edulis) in the state of Valle del Cauca (Colombia) has been determined. The complete DNA-A and DNA-B components were determined to be 2600 and 2572 nt in length, respectively. The DNA-A showed the highest nucleotide sequence identity (87.2 %) to bean dwarf mosaic virus (M88179), a begomovirus found in common bean crops in Colombia, and only 77.4 % identity to passion fruit severe leaf distortion virus (FJ972767), a begomovirus identified infecting passion fruit in Brazil...

BACKGROUND: Cancer cells rapidly acquire resistance leading to treatment failures. In the present study, we have evaluated the cytotoxicity of 17 methanol extracts from 11 Cameroonian medicinal plants against the sensitive leukemia CCRF-CEM cells and the best ones were further tested on a panel of 8 other human cancer cell lines, including various MDR phenotypes as well as against the normal AML12 hepatocytes. METHODS: The cytotoxicity of the extracts was determined using a resazurin reduction assay meanwhile flow cytometry was used to measure cell cycle, apoptosis, mitochondrial membrane potential (MMP), and reactive oxygen species...

Piceatannol (3,3',4',5-trans-tetrahydroxystilbene) is a polyphenolic compound abundant in the seeds of passion fruit (Passiflora edulis). Piceatannol is an analogue of resveratrol (3,4',5-trans-trihydroxystilbene) and shares the structural motif and biological activities such as activation of SIRT1. Several studies have shown that piceatannol is more potent than resveratrol. In this study, we examined the effects of piceatannol on neural stem cell differentiation into astrocytes compared with those of resveratrol...

Previous studies have shown that fruits have different effects on alcohol metabolism and alcohol-induced liver injury. The present work selected three fruits and aimed at studying the effects of Syzygium samarangense, Passiflora edulis and Solanum muricatum on alcohol-induced liver injury in mice. The animals were treated daily with alcohol and fruit juices for fifteen days. Chronic treatment with alcohol increased the levels of aspartate transaminase (AST), alanine transaminase (ALT), total bilirubin (TBIL), triglyceride (TG), malondialdehyde (MDA), and decreased total protein (TP)...

Passiflora plants are strategic in the context of biodiversity for food and nutrition. We applied the procedures of a systematic review protocol to study the state of the art on identification of phenolic compounds from Passiflora plants. An automated literature search was conducted using six databases and a combination of seven keywords. All the analytical, chromatographic, and spectroscopic methods were included. The studies were classified according to their method of identification, phenolic classes, and method of extraction...

In the warfare between herbivore and host plant, insects have evolved a variety of defensive mechanisms, including allelochemical transformation and excretion. Several studies have explored the transcriptome responses of insects after host plant shifts to understand these mechanisms. We investigated the plastic responses of Heliconius melpomene larvae feeding on a native host Passiflora menispermifolia and a less strongly defended nonhost species, Passiflora biflora. In total, 326 differentially expressed genes were identified, with a greater number upregulated on the more strongly defended native host...
