Thus, more studies investigating the safety of V. polyanthes aqueous extract before the use are needed. The purpose of this study was to evaluate the toxicity, cytotoxicity and genotoxicity of V. polyanthes leaves aqueous extract using the Artemia salina and Allium cepa assays. For the A. salina assay, three groups of 10 larvae were exposed to V. polyanthes leaves aqueous extract at the concentrations of 5, 10, 20, 40, and 80 mg/ml. For the A. cepa assay, 5 onion bulbs were exposed to V. polyanthes leaves aqueous extract at 10, 20, and 40 mg/ml, and then submitted to macroscopic and microscopic analysis. As result it was identified a toxicity and cytotoxicity ofV. polyanthes dependent on the extract concentration. -

Phenotypic Landscape Inference Reveals Multiple Evolutionary Paths to C4 Photosynthesis
RESEARCH ARTICLE elife.elifesciences.org Phenotypic landscape inference reveals multiple evolutionary paths to C4 photosynthesis Ben P Williams1†, Iain G Johnston2†, Sarah Covshoff1, Julian M Hibberd1* 1Department of Plant Sciences, University of Cambridge, Cambridge, United Kingdom; 2Department of Mathematics, Imperial College London, London, United Kingdom Abstract C4 photosynthesis has independently evolved from the ancestral C3 pathway in at least 60 plant lineages, but, as with other complex traits, how it evolved is unclear. Here we show that the polyphyletic appearance of C4 photosynthesis is associated with diverse and flexible evolutionary paths that group into four major trajectories. We conducted a meta-analysis of 18 lineages containing species that use C3, C4, or intermediate C3–C4 forms of photosynthesis to parameterise a 16-dimensional phenotypic landscape. We then developed and experimentally verified a novel Bayesian approach based on a hidden Markov model that predicts how the C4 phenotype evolved. The alternative evolutionary histories underlying the appearance of C4 photosynthesis were determined by ancestral lineage and initial phenotypic alterations unrelated to photosynthesis. We conclude that the order of C4 trait acquisition is flexible and driven by non-photosynthetic drivers. This flexibility will have facilitated the convergent evolution of this complex trait. DOI: 10.7554/eLife.00961.001 Introduction *For correspondence: Julian. The convergent evolution of complex traits is surprisingly common, with examples including camera- [email protected] like eyes of cephalopods, vertebrates, and cnidaria (Kozmik et al., 2008), mimicry in invertebrates and †These authors contributed vertebrates (Santos et al., 2003; Wilson et al., 2012) and the different photosynthetic machineries of equally to this work plants (Sage et al., 2011a). -

RESUMEN Introducción: Vernonanthura patens (Kunth) H. Rob., arbusto originario de Sudamérica, crece silvestre en el sur ecuatoriano; los pobladores del cantón Marcabelí, provincia del Oro, la conocen como laritaco y utilizan las cocciones acuosas de las hojas para lavar y cicatrizar las heridas, calmar el dolor de cabeza, como antiinflamatorio, calmar la tos y combatir ciertos tipos de cáncer. Las investigaciones biológicas preliminares realizadas han demostrado una buena actividad antimalárica y antileishmaniasis. No existen, sin embargo, antecedentes de otras investigaciones farmacológicas ni químicas para la especie. Objetivo: determinar los parámetros físico-químicos de calidad de las flores, hojas y ramas de la especie en estado de fructificación, y los metabolitos secundarios presentes en estos órganos vegetales a través del tamizaje fitoquímico. Métodos: la planta se recolectó en estado adulto, en época de floración, los órganos vegetales secados en estufa se molinaron hasta tamaño de partícula 2 mm. Los índices numéricos se determinaron según la norma ramal de salud pública 309 de 1992, y el tamizaje fitoquímico se realizó según metodología analítica de Miranda y Cuéllar. -
Vulnerability and Adaptation to Climate Change in the Semi-Arid Regions of Southern Africa
Vulnerability and Adaptation to Climate Change in the Semi-Arid Regions of Southern Africa 1 About ASSAR Working Papers This series is based on work funded by Canada’s International Development Research Centre (IDRC) and the UK’s Department for International Development (DFID) through the Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA). CARIAA aims to build the resilience of vulnerable populations and their livelihoods in three climate change hot spots in Africa and Asia. The program supports collaborative research to inform adaptation policy and practice. Titles in this series are intended to share initial findings and lessons from research and background studies commissioned by the program. Papers are intended to foster exchange and dialogue within science and policy circles concerned with climate change adaptation in vulnerability hotspots. As an interim output of the CARIAA program, they have not undergone an external review process. Opinions stated are those of the author(s) and do not necessarily reflect the policies or opinions of IDRC, DFID, or partners. Feedback is welcomed as a means to strengthen these works: some may later be revised for peer-reviewed publication.
