Using whole body elemental fingerprint analysis to distinguish different populations of Coilia nasus in a large river basin
The objective of the present study was to screen these populations by the means of the whole body elemental fingerprint analysis (EFA). Our results showed that the diadromous population had significantly lower concentrations of Al, B, Ca, Cr, Fe, K, Mg, Mn, P, S, and Zn, and significantly higher As than the residential populations. The spawners had lower concentrations of B, Cr, P, and S before laying eggs than after laying eggs. Advanced statistical models detected distinct spatial patterns between the diadromous and residential populations, and between groups before and after spawning. The current study showed that the w...

Freshwater sponges, native to rivers and lakes, have been studied chemically throughout the world, but there have been no studies on sponges from the Amazon r...

Isolation and characterization of thirteen microsatellite loci in four diploid species of Ranunculus cantonensis polyploid complex
Publication date: June 2015 Source:Biochemical Systematics and Ecology, Volume 60 Author(s): Tongjian Li , Lingling Xu , Yuanfang Deng , Liang Liao , Guolu Liang Ranunculus is a cosmopolitan genus, and the evolution of the genus has been influenced by both polyploidy and hybridization. The interactions between some species of Ranunculus are regarded as a natural model system for studying hybridization. Four diploid species of the R. cantoniensis polyploid complex have relatively little reproductive isolation from each other, and they form a complicated hybrid pool in a multispecies hybrid zone. To clarify the genetic str...

Chloroplast phylogeography of a desert shrub, Calligonum calliphysa (Calligonum, Polygonaceae), in arid Northwest China
Publication date: June 2015 Source:Biochemical Systematics and Ecology, Volume 60 Author(s): Zhibin Wen , Zhe Xu , Hongxiang Zhang , Ying Feng In order to investigate the influence of Pleistocene climate oscillations and paleogeographic events on the evolutionary history of xerophytic plants in arid Northwest China, the phylogeography of a well adapted desert shrub, Calligonum calliphysa (Calligonum, Polygonaceae), was studied. A total of 11 natural populations and 90 individuals were sampled. Two cpDNA intergenic spacer regions (rpl32-trnL and ycf6-psbM) were sequenced and 13 haplotypes were identified. Significant gene...

Lectin genes and their mature proteins: Still an exciting matter, as revealed by biochemistry and bioinformatics analyses of newly reported proteins
Publication date: June 2015 Source:Biochemical Systematics and Ecology, Volume 60 Author(s): Andreia Varmes Fernandes , Márcio Viana Ramos , José Hélio Costa , Ilka Maria Vasconcelos , Renato de Azevedo Moreira , Frederico Bruno Mendes Batista Moreno , Maria Eliza Caldas dos Santos , José Francisco de Carvalho Gonçalves Two new lectins were purified through affinity chromatography after crude extract preparation under high ionic strength. The hemagglutinating activity of these lectins from the seeds of the legumes Dioclea bicolor (DBL) and Deguelia scandens (DSL) was inhibited by galact...

Development of EST-derived SSR markers using next-generation sequencing to reveal the genetic diversity of 50 chrysanthemum cultivars
Publication date: June 2015 Source:Biochemical Systematics and Ecology, Volume 60 Author(s): Kyoung-Min Jo , Yeonhwa Jo , Hyosub Chu , Sen Lian , Won Kyong Cho Chrysanthemum plants are popular worldwide as cut flowers, potted, and in gardens. Several hundred cultivars have been commercialized, indicating that there is substantial genetic variations that can be manipulated under cultivations to produce a wide array of phenotypic variation. To study the genetic diversity of chrysanthemum cultivars in Korea, we first identified simple sequence repeats from chrysanthemum expressed sequence tags generated by FLX 454 sequencin...

Increased genetic diversity in the populations of Echium vulgare L. colonising Zn–Pb waste heaps
Publication date: June 2015 Source:Biochemical Systematics and Ecology, Volume 60 Author(s): Sławomir Dresler , Mirosław Tyrka , Magdalena Szeliga , Joanna Ciura , Jerzy Wielbo , Małgorzata Wójcik , Anna Tukiendorf Echium vulgare L. (Boraginaceae) is a tetraploid pseudometallophyte plant commonly occurring on dry, coarse textured soils as well as on heavy metal contaminated substrates. In the present study, the genetic diversity and differentiation of two populations of E. vulgare originating from Zn–Pb mining and smelting waste deposits (MP, MB populations) and one from uncontaminated soil (NM population...
