Plants from the family Passiflora have been used in standard drug by various social orders. Flavonoids, glycosides, alkaloids, phenolic blends and eccentric constituents have been represented as the major phyto- constituents of the Passiflora spe-cies. This overview delineates the morphology, standard and tales uses, phyto- constituents and pharmacological reports of the prominent kinds of the sort Passiflora. Diverse virgin areas of investigation on the kinds of this sort have been highlighted to examine, detach and recognize the therapeutically huge phyto- constituents which could be utilized to help various diseases impacting the mankind. The objective of the current examination was to concentrate all Passiflora species. The sythesis of each specie presented particularities; this legitimizes the essentialness of studies concentrating on the phenolic bit of different Passiflora species.

  • The Zebra Longwing Butterfly
    A Special Visitor to West Central Louisiana and Almost Eden: The Zebra Longwing Butterfly For the first time this past fall we were graced with the presence of Zebra Longwing Butterflies, Heliconius charithonia. These big bold beautiful butterflies are ‘sometimes visitors’ to the warm southern and more tropical regions of Louisiana and are permanent residents of Florida (their state butterfly) and the Lower Rio Grande Valley of south Texas. They migrate north to other portions of the US and have been reported from as far north as Illinois, Colorado, Virginia, and even New York (you think they could have shown up a little sooner, lol). They were here from October until mid-December of 2016. This is one of the easiest butterflies to recognize and of the first a budding butterfly enthusiast like myself to have learned and one I had always yearned to see. Their long delicate wings and seemingly non-stop fluttering give rise to a fairy-like appearance. The long dark wings with broad bold wide buttery yellow stripes are actually warning signs to predators that this butterfly is poisonous due to the fact that the caterpillars consume Passionvines which have poisonous components that the insects take up as a defense against predation in the same way the Monarch butterfly does. The Zebra Longwing is reported to have spatial memory and will return to the same plants each day in search of nectar. And like the Julia, they also have an especially strong affinity for the flowers of Lantana but are not against visiting other similarly nectar rich species such as Porterweed, Mexican Firebush, and Pentas.

  • Reconstructing the Basal Angiosperm Phylogeny: Evaluating Information Content of Mitochondrial Genes
    55 (4) • November 2006: 837–856 Qiu & al. • Basal angiosperm phylogeny Reconstructing the basal angiosperm phylogeny: evaluating information content of mitochondrial genes Yin-Long Qiu1, Libo Li, Tory A. Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships.

    GUIDE TO THE GENERA OF LIANAS AND CLIMBING PLANTS IN THE NEOTROPICS PASSIFLORACEAE By Christian Feuillet & P. Acevedo-Rodríguez (Feb 2020) A predominantly tropical family with few species reaching warm-temperate regions, of about 15-17 genera and 850 species of tendrilled lianas or vines, or sometimes shrubs, small trees, or annuals with a perennial rootstock or a fleshy caudex. Represented in the Neotropics by 4 genera and about 600 species, occupying diverse habitats, from savanna to flooded forests, but most abundant in tropical rain forests on terra firme. Most species occur at low to middle elevations, but some grow above the tree line on Andean slopes. Diagnostics: Distinguished by the flowers with Dilkea sp., photo by L. Marinho an extrastaminal corona and usually a gynophore, and by the common presence of petiolar nectaries. Sterile collections of Passifloraceae may be confused with members of Cucurbitaceae as both families may have simple, alternate leaves, axillary tendrils, and petiolar nectaries. However, Passifloraceae is differentiated by the presence of stipules, unbranched axillary tendrils (trifid in Dilkea) [vs. exstipulate and axillary-lateral tendrils (forming a 90º angle with the petiole) that are commonly branched in Cucurbitaceae]. Also, resembles Vitaceae but tendrils and inflorescence in this family are opposite to the leaves, not axillary. 1 General Characters 1. STEMS. Stems are woody or herbaceous depending on the species. Woody, mature stems are usually 1 to 2 cm in diameter, although in cultivated Passiflora they may reach 8 cm or more in diameter, and up to 25 m in length. Stems are cylindrical (figs. 1a & b), trigonous (fig.

However, few data about the chemical composition and the medicinal potential of in vitro derived materials are available. Therefore, the goal of this work was to compare, for the first time, the phytoconstituents of in vitro derived materials of four Passiflora species, and evaluate the antibacterial potential of their extracts against 20 Gram-positive and negative strains. Chromatographic analysis indicated the presence of saponins in roots extracts from all studied species, whereas leaf extracts presented both saponins and flavonoids.

Foram utilizados três níveis de nitrogênio no solo (tratamentos) para o cultivo de P. suberosa: 0, 150 e 300 mg L-1. Larvas recém-eclodidas foram criadas em laboratório (25 ± 1ºC), individualmente, em ramos das plantas cultivadas em cada tratamento e fêmeas capturadas em campo foram submetidas a testes de escolha para oviposição. A taxa de crescimento, a área foliar e o comprimento dos internódios de P. suberosa aumentaram significativamente com a adição de nitrogênio. A dureza das folhas jovens nas plantas cultivadas sem adição de nitrogênio foi maior, as quais também apresentaram menor conteúdo de água.

HORTICULTURE M.S. CROP SCIENCE ***** The Ohio State University 2008 Dissertation Committee: Dr. Daniel K. Struve, Advisor Approved by: Dr. John Finer, Dr. Mark Bennett, _______________________________ Dr. Landon Rhodes. Advisor Horticulture and Crop Science Graduate Program Copyright by Gesimba Robert Morwani 2008 ABSTRACT Drought and Fusarium wilt are the main constraints in growing purple passion fruit (Passiflora edulis) in Kenya. There is need for drought and Fusarium wilt-resistant rootstock. In an effort to develop a drought and Fusarium wilt resistant Passiflora rootstock, a series of experiments were conducted at The Ohio State University and Egerton University in Kenya, to study vegetative propagation, graft compatibility, drought tolerance, Fusarium wilt resistance in Passiflora species and to identify an integrated control method for Fusarium wilt. In the vegetative propagation, graft compatibility and drought tolerance studies, 20 Passiflora species were screened. Species of the subgenus Passiflora rooted in higher percentages than species of the Decaloba subgenus (81 vs 64%). Cuttings from vines and liana type species rooted in higher percentages than cuttings from annual species when treated with 0.1% indole-3-butyric acid powder (82, 73 vs 44%). Cuttings of Passiflora gerbertii L., Passiflora caerulea L. and Passiflora subpeltata Ortega. could be rooted in high percentages and were compatible rootstocks with the purple passion fruit.
