In vitro simulation studies of silica deposition induced by lignin from rice

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2006年第4期7卷 267-271页

作者： FANG Jiang-yu MA Xue-long institute of biodiversity Research Huangshan University Huangshan 245021 China Tea Biochemistry and Biotechnology Laboratory of Ministry of Agriculture Anhui Agricultural University Hefei 230036 China

To reveal the possible mechanism of silica deposition in higher plants, lignin was isolated from rice straw following a modified method to conduct a simulation experiment in vitro. UV and infrared absorption spectra showed that the substance had the unique characteristics of pure lignin. The presence of silicon in the precipitation was revealed by TEM (transmission electron microscopy) with EDXA (energy dispersive X-ray analysis) device. It was found that in the borax solution where lignin precipi-tation occurred silica-lignin co-precipitation was produced but not in the DMSO solution where lignin was broken into its com-position compounds and did not precipitate. This means that it is macromolecular lignin itself but not its compounds that could induce silica deposition in higher plants.

Tibetan Plateau Relict Snakes of the Genus Thermophis and Their Relationship to New World Relict Snakes

引用

Asian Herpetological Research 2011年第3期2卷 161-168页

作者： Xiaoyu SUN Shaoying LIU Song HUANG College of Life and Environment Sciences Huangshan University institute of biodiversity and Geobiology Department of Life SciencesTibet University State Key Laboratory of Genetic Resources and Evolution Kunming Institute of ZoologyChinese Academy of Sciences Sichuan Academy of Forestry

The complete mitochondrial NADH dehydrogenase subunit 2(ND2) gene sequences of two species of Thermophis, T. baileyi and T. zhaoermii, were sequenced and compared to those of 86 sequences from other snakes(74 from Caenophidia and 12 from Henophidia). By using Bayesian inference(BI) and maximum likehood(ML) approaches, Thermophis was demonstrated as the sister group to the North American relicts of Dipsadinae, and rooted in Central and South American members of this subfamily. The results suggest that the closest relatives of Thermophis are the North American relicts, and thus support the hypothesis for an Asian-North American origin of xenodontine snakes as suggested by Vidal et al.(2000). Extensive sampling of Asian snakes and American dipsadines is needed to further test this hypothesis in the future.

Uptake and accumulation of phenanthrene and pyrene in spiked soils by Ryegrass(Lolium perenne L.)

引用

Journal of Environmental Sciences 2005年第5期17卷 817-822页

作者： XU Sheng-you CHEN Ying-xu LIN Qi WU Wei-xiang XUE Sheng-guo SHEN Chao-feng Department of Environmental Engineering Zhejiang University Hangzhou 310029 China Department of Resource and Environment Huangshan University Huangshan 245000 China

Phytoremediation has long been recognized as a cost-effective method for the removal of polycyclic aromatic hydrocarbons （PAHs） from soil. A study was conducted to investigate the uptake and accumulation of PAHs in root and shoot of Lolium perenne L. Pot experiments were conducted with series of concentrations of 3.31-378.37 mg/kg for phenanthrene and those of 4.22-365.38 mg/kg for pyrene in a greenhouse. The results showed that both ryegrass roots and shoots did take up PAHs from spiked soils, and generally increased with increasing concentrations of PAH in soil. Bioconcentration factors（BCFs） of phenanthrene by shoots and roots were 0.24- 4.25 and 0.17-2.12 for the same treatment. BCFs of pyrene by shoots were 0.20-1.5, except for 4.06 in 4.32 mg/kg treatment, much lower than BCFs of pyrene by roots （0.58-2.28）. BCFs of phenanthrene and pyrene tended to decrease with increasing concentrations of phenanthrene and pyrene in soil. Direct uptake and accumulation of these compounds by Lolium perenne L. was very low compared with the other loss pathways, which meant that plant-promoted microbial biodegradation might be the main contribution to plant-enhanced removal of phenanthrene and pyrene in soil. However, the presence of Lolium perenne L. significantly enhanced the removal of phenanthrene and pyrene in spiked soil. At the end of 60 d experiment, the extractable concentrations of phenanthrene and pyrene were lower in planted soil than in non-planted soil, about 83.24%-91.98% of phenanthrene and 68.53%-84.10% of pyrene were removed from soils, respectively. The results indicated that the removal of PAHs in contaminated soils was a feasible approach by using Lolium perenne L.

Relationship of Old World Pseudoxenodon and New World Dipsadinae,with Comments on Underestimation of Species Diversity of Chinese Pseudoxenodon

引用

Asian Herpetological Research 2013年第3期4卷 155-165页

作者： Baolin ZHANG Song HUANG College of Life and Environment Sciences Huangshan University School of Life Sciences Yunnan University State Key Laboratory of Genetic Resources and Evolution Kunming Institute of ZoologyChinese Academy of Sciences institute of biodiversity and Geobiology Department of Life SciencesTibet University

Assessment of the relationship between Pseudoxenodon and Dipsadinae has been hampered by lack of adequate samples. In this paper, we conducted phylogenetic analyses using two mitochondrial genes （12S and 16S rRNA） and one nuclear gene （c-mos） from thirteen specimens representing two species of Pseudoxenodon, together with 84 sequences of caenophidians and an outgroup sequence of Boa constrictor. Our study suggests that the Southeast Asian genus, Pseudoxenodon forms a robust genetic subclade within South American xenodontines, indicating that at least one lineage within this genus entered or returned to the Old World （OW） from the New World （NW） across the Beringian Land Bridge during the early Tertiary and the warm mid-Miocene. It also reveals the high intraspecific genomic variation within the populations of Pseudoxenodon macrops, indicating that species diversity of Pseudoxenodon in China is likely underestimated.

Six main mitochondrial DNA （mtDNA） lineages have been described in minnow （Zacco platypus） samples obtained from northern, western and southern China Perdices et al. （2004） predicted that further sampling of other tributaries might discover more lineages of this species. In this study, we collected 26 Zacco platypus individuals in the huangshan area of eastern China and determined the cytochrome b （cytb） sequence variations. Combined with reported data in GenBank, we identified ten matrilines （Zacco A-J） in a total of 169 samples, with relatively high molecular divergence found among them. The huangshan population had the greatest genetic variation among all sampled regions and hosted six of the ten matrilines. Our results highlight the significance of the huangshan area for the conservation of Zacco platypus.
