Therefore, the present study was to evaluate the antioxidant potential of ethanolic extract of Mollugo cerviana(L.)Ser.(EEMC) using porcine liver slices. The porcine liver slices were induced for oxidative stress using Hydrogen peroxide and treated with EEMC was evaluated for its antioxidant activity using standard procedures. Results obtained in the present study shows the significant difference in the levels of antioxidants among all the groups were used. It is suggested that the EEMC serve as a free radical scavenger and acting as antioxidants in preventing many ailments. KEY WORDS Mollugo cerviana(L.)Ser., Porcine liver slices, Free radicals, Oxidative stress, Antioxidants INTRODUCTION might not have the ability to protect cells from oxidative Excessive generation of free radicals and reactive stress and thereby, necessitate the supplement from oxygen species (ROS) are due to the exposure to exogenous antioxidants. Due to this requirement, many external oxidant substances or the biological system synthetic antioxidants developed to mitigate oxidative loss its defense mechanisms against these oxidants damage but it’s one of the disadvantages is these causes oxidative stress. Further, it leads to various substances are of high cost, less availability and also has deteriorating diseases such as aging, cancer, health risk. To overcome this complication, synthetic cardiovascular disease, cataracts and also decline in the antioxidants were replaced by natural antioxidants and immune system and dysfunction of brain [1,2]. plays an effective role in protection from ROS and curing [6] Lipids present in the membrane are more prone to the diseases . These natural antioxidants derived from attack of free radicals and subsequently breakdown the plant sources contains bioactive compounds like chain reaction and causes lipid peroxidation.

  • 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.

E-mail: [email protected] Received 30 November 2010; Revised 1 February 2011; Accepted 2 February 2011 Abstract Using isotopic screens, phylogenetic assessments, and 45 years of physiological data, it is now possible to identify most of the evolutionary lineages expressing the C4 photosynthetic pathway. Here, 62 recognizable lineages of C4 photosynthesis are listed. Thirty-six lineages (60%) occur in the eudicots. Monocots account for 26 lineages, with a Downloaded from minimum of 18 lineages being present in the grass family and six in the sedge family. Species exhibiting the C3–C4 intermediate type of photosynthesis correspond to 21 lineages. Of these, 9 are not immediately associated with any C4 lineage, indicating that they did not share common C3–C4 ancestors with C4 species and are instead an independent line. The geographic centre of origin for 47 of the lineages could be estimated. These centres tend to jxb.oxfordjournals.org cluster in areas corresponding to what are now arid to semi-arid regions of southwestern North America, south- central South America, central Asia, northeastern and southern Africa, and inland Australia.

  • The Occurrence of C4 Plants and Their Morphological Functional Types in the Vegetation of Xinjiang, China
    PHOTOSYNTHETICA 44 (2): 293-298, 2006 The occurrence of C4 plants and their morphological functional types in the vegetation of Xinjiang, China R.Z. WANG Laboratory of Quantitative Vegetation Ecology, Institute of Botany, the Chinese Academy of Sciences, No. 20 Nanxincun, Xiangshan, Beijing, 100093, China Abstract Floristic composition, morphological functional types and habitat distributions for C4 species were studied in Xinjiang, North-western China. 89 species, in 9 families and 41 genera, were identified with C4 photosynthesis. 48 % of these C4 species were found in Monocotyledoneae, e.g. Cyperaceae (5 species), Gramineae (38 species), the other 52 % was in Dicotyledoneae, e.g. Chenopodiaceae (29 species), Amaranthaceae (7 species), and Polygonaceae (5 species). Compared with those in semi-arid grasslands in North China and tropical forests in South China, more plant families were found with the occurrence of C4 plants in this arid region. Relatively higher annual species (63 %), shrubs (18 %), and Chenopodiaceae C4 species (33 %) compositions were the primary characteristics for the C4 species occurring in Xinjiang, and this was remarkably related with its arid environment. More Chenopodiaceae C4 species occurring in the region suggested that this type of C4 species may have higher capacity to fit the air and soil droughts. There was a strong relationship between C4 occurrence and habitat distributions, more than half of the total 89 C4 species were found in disturbed and cultivated lands and early stages of vegetation successions, indicating C4 occurrence was not only related with climate changes, but also with land uses and vegetation dynamics. Additional key words: annual C4 species; arid region; habitats.

    Vascular Plant Species of the Comanche National Grassland in United States Department Southeastern Colorado of Agriculture Forest Service Donald L. Hazlett Rocky Mountain Research Station General Technical Report RMRS-GTR-130 June 2004 Hazlett, Donald L. 2004. Vascular plant species of the Comanche National Grassland in southeast- ern Colorado. Gen. Tech. Rep. RMRS-GTR-130. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 36 p. Abstract This checklist has 785 species and 801 taxa (for taxa, the varieties and subspecies are included in the count) in 90 plant families. The most common plant families are the grasses (Poaceae) and the sunflower family (Asteraceae). Of this total, 513 taxa are definitely known to occur on the Comanche National Grassland. The remaining 288 taxa occur in nearby areas of southeastern Colorado and may be discovered on the Comanche National Grassland. The Author Dr. Donald L. Hazlett has worked as an ecologist, botanist, ethnobotanist, and teacher in Latin America and in Colorado. He has specialized in the flora of the eastern plains since 1985. His many years in Latin America prompted him to include Spanish common names in this report, names that are seldom reported in floristic pub- lications. He is also compiling plant folklore stories for Great Plains plants. Since Don is a native of Otero county, this project was of special interest.
