Pollution can be aggravated in industrial areas if traffic exhausts are mixed with industrial emissions under high humidity conditions. Plants growing in such environments may suffer from severe stress. The impact of vehicle emissions on urban vegetation in an industrial area in Qingdao, China, was investigated by studying seven plant species at visible, physiological and chemical levels. The traits of plant species in certain environmental conditions were compared between a clear area, Badaguan （BDG）, and polluted area, Roadside （RS）. We found that foliar sulfur uptake for all species was not significantly high at RS compared with BDG, although the sulfur content of atmosphere and surface soils at RS were much higher than those at BDG. For Ailanthus altissima Swingle, the content of foliar pigment and net photosynthesis rate （PN） decreased by 20%. Meanwhile, leaves became incrassate and no visible leaf damage was noted, suggesting this species could adapt well to pollution. A 50% decrease in PN occurred in Hibiscus syriacus L., but there was no statistical change in content of chlorophyll a and b and water uptake. Also, thickened leaves may prevent the pollutant from permeation. Foliar water content was still at a low level, although a water compensation mechanism was established for Fraxinus chinensis Rosb. reflected by low water potential and high water use efficiency. More adversely, a 65% decrease in PN happened inevitably with the significant decomposition of photosynthetic pigments, which exhibited visible damage. We also noted in one evergreen species （Magnolia grandifiora L.） that water absorption driven by low water potential should be helpful to supply water loss induced by strong stomatal transpiration and maintain normal growth. Furthermore, photosynthetic pigment content did not decline statistically, but supported a stable net assimilation. Two herbaceous species, Poa annua L. and Ophiopogon japonicus Ker-Gawh, were very tolerant to adverse stress com

A STUDY OF The SURFACE EMERGING PALAEOCHANNELS ON The SOUTH COAST PLAIN OF LAIZHOU BAY

引用

Chinese Geographical Science 2000年第3期10卷 54-62页

作者： Mei Han dao-gao Li Ming-hua Zhao Ai-xia jiang Department of Geography Shandong Normal University Jinan P. R. China

By employing many methods including distinguishing the land maps, interpreting the aerophotoes and Satellite photographes, consulting historical documents, investigating ancient cultural relics, making investigations in the field, analysing the names and features of the place, and analysing the characteristics of the deposit, etc., a systematic study of the surface emerging palaeochannels on the South Coast Plain of Laizhou Bay has been made. Twenty five surface emerging palaeochannels were discovered and verified. According to the formation age, these palaeochannels were divided into two stages: six palaeochannels were formed in the Early and Middle Holocene, and nineteen palaeochannels were formed in the Late Holocene(the historical period). According to the landform features, the palaeochannels are divided into four categories: upland palaeochannel belts, strip shaped upland palaeochannels, trough shaped depression palaeochannels and ancient riverbeds. Among the four categories, the strip shaped upland palaeochannels are the main types. The swinging and movement of the channels helped the alluvial plains expand and cause the coastal ancient lakes to vanish in succession.

Molecular phylogeny of Pamphagidae （Acridoidea, Orthoptera） from China based on mitochondrial cytochrome oxidase II sequences

引用

Insect Science 2011年第2期18卷 234-244页

作者： dao-Chuan Zhang Hong-Yan Han Hong Yin Xin-jiang Li Zhan Yin Xiang-Chu Yin College of Life Sciences Hebei University Baoding Hebei Province College of Plant Protection Shandong Agncultural University Taian Shandong Province China

Phylogenetic relationships of Pamphagidae were examined using cytochrome oxidase subunit II （COIl） mtDNA sequences （684 bp）. Twenty-seven species of Acridoidea from 20 genera were sequenced to obtain mtDNA data, along with four species from the GenBank nucleotide database. The purpose of this study was analyzing the phylogenetic relationships among subfamilies within Pamphagidae and interpreting the phylogenetic position of this family within the Acridoidea superfamily. Phylogenetic trees were reconstructed using neighbor-joining （NJ）, maximurn parsimony （MP） and Bayesian inference （BI） methods. The 684 bp analyzed fragment included 126 parsimony informative sites. Sequences diverged 1.0%-11.1% between genera within subfamilies, and 8.8%-12.3% between subfamilies. Amino acid sequence diverged 0-6.1% between genera within subfamilies, and 0.4%-7.5% between subfamilies. Our phylogenetic trees revealed the monophyly of Pamphagidae and three distinct major groups within this family. Moreover, several well supported and stable clades were found in Pamphagidae. The global clustering results were similar to that obtained through classical morphological classification： Prionotropisinae, Thrinchinae and Pamphaginae were monophyletic groups. However, the current genus Filchnerella （Prionotropisinae） was not a monophyletic group and the genus Asiotmethis （Prionotropisinae） was a sister group of the genus Thrinchus （Thrinchinae）. Further molec- ular and morphological studies are required to clarify the phylogenetic relationships of the genera Filchnerella and Asiotmethis.

Protein Extraction Methods for Two-Dimensional Electrophoresis from Baphicacanthus cusia(Nees)Bremek Leaves-A Medicinal Plant with High Contents of Interfering Compounds

引用

Agricultural Sciences in China 2010年第10期9卷 1530-1537页

作者： XIANG Xiao-liang NING Shu-ju jiang Xia GONG Xiao-gui ZHU Ren-lei WEI dao-zhi School of Life Sciences Fujian Agriculture and Forestry University Fuzhou 350002 P.R. China School of Crop Sciences Fujian Agriculture and Forestry University Fuzhou 350002 P.R. China College of Chemistry and Materials Science Fujian Normal University Fuzhou 350002 P.R. China

Protein extraction is a critical step for two-dimensional electrophoresis （2-DE）. Different plant samples require different and adaptive protein extraction protocols. The leaves of medicinal plant, Baphicacanthus cusia （Nees） Bremek are notoriously recalcitrant to common protein extraction methods due to high levels of interfering compounds （especially the secondary metabolites and pigments）. This study was aimed to establish a routine procedure for the proteomic analysis ofB. cusia leaves, and a new protocol for the protein extraction was developed by optimizing trichloroacetic acid （TCA）/ acetone extraction method. The efficiency of this protocol was demonstrated by comparison with 3 published protein extraction methods （chloroform/acetone, Mg/NP-40, Tris-base/acetone）. The results showed that the optimized TCA/ acetone precipitation extraction method gave a relatively high protein yield （9.263 mg g^-1 fresh weight）, high-resolution separation, clear protein profiles, the highest proteins spots （1 31 t protein spots）, and displayed less contamination in 2- DE gels. Therefore, the results suggested that the optimized TCA/acetone method was the most effective among the 4 methods for B. cusia leaves.
