DNA barcoding in medicinal plants: Testing the potential of a proposed barcoding marker for identification of Uncaria species from China
In this study, we tested the feasibility of five candidate DNA barcodes (nrITS, nrITS2, matk, rbcL and trnH-psbA) for identifying Uncaria species. We collected a total of 54 specimens of 10 Uncaria species across its distributional range. BLAST, barcoding gaps, tree-based methods and TAXONDNA analysis were used to investigate the molecular identification capability of the candidate DNA barcodes. The results showed that the ITS2 is most suitable as a candidate DNA barcode for identification of medicinal plants of the genus Uncaria. (Source: Biochemical Systematics and Ecology)

Exon primed intron-crossing (EPIC) markers reveal natural hybridization and introgression in Actinidia (Actinidiaceae) with sympatric distribution
In this study, phylogenetic relationships of Actinidia species with sympatric distributions were investigated using three chloroplast introns (trnL-F, atpB-rbcL and rpl32-trnL) and three Exon primed intron-crossing (EPIC) markers. Chloroplast phylogeny supports non-monophyly of the five species studied excluding Actinidia fulvicoma var. lanata. The non-monophyly was also revealed by EPIC markers. Our results showed EPIC markers are more variable and informative for phylogenetic inference than that of chloroplast markers. The incongruences between loci from the plastid and nuclear DNA phylogenic trees may stem from incomple...

Genetic diversity and structure of the noxious alien grass Praxelis clematidea in southern China
We examined the genetic variation and population structure of 12 populations (76 individuals) of P. clematidea from Fujian, Guangdong, and Hainan Provinces in China using inter-simple sequence repeat (ISSR) analysis. From an initial set of 69 ISSR primers, 10 were selected which yielded 80 reproducible bands. Polymorphic bands (P) were 100%, Shannon's information index (I) was 0.4226, and Nei's gene diversity (H) was 0.2791. We infer that the high levels of genetic diversity exhibited by P. clematidea may have contributed to its invasiveness. Gene flow among populations was 2.4930, which has led to homogenization.

In this study, DNA barcoding was used in the identification of potential biological control agents of sunn pest adult parasitoid species, including Eliozeta helluo (F.), Phasia subcoleoptrata (L.), Ectophasia crassipennis (F.) and Elomyia lateralis (Meig). DNA analyses were assessed by sequencing cytochrome c oxidase subunit I (COI) gene. The obtained sequences were analyzed in terms of nucleotide composition, nucleotide pair frequency and haplotype diversity. Genetic divergence among haplotypes was estimated by constructing genetic distance matrix using DNA sequence variations, by Kimura 2-parameter model. Variable sites ...

Transferability of Cucurbita SSR markers for genetic diversity assessment of Turkish bottle gourd (Lagenaria siceraria) genetic resources
Publication date: April 2015 Source:Biochemical Systematics and Ecology, Volume 59 Author(s): Mehtap Yildiz , Hugo E. Cuevas , Suat Sensoy , Ceknas Erdinc , Faheem S. Baloch The genetic diversity present in crop landraces represents a valuable genetic resource for breeding and genetic studies. Bottle gourd (Lagenaria siceraria) landraces in Turkey are highly genetically diverse. However, the limited genomic resources available for this crop hinder the molecular characterization of Turkish bottle gourd germplasm for its adequate conservation and management. Therefore, we evaluated the efficacy of 40 SSR markers from major...

Similarity in the feeding ecology of parrotfish (Scaridae) in coral reef habitats of the Malaysian South China Sea, as revealed by fatty acid signatures
Publication date: April 2015 Source:Biochemical Systematics and Ecology, Volume 59 Author(s): Takaomi Arai , Razikin Amalina , Zainudin Bachok To understand the trophic ecology and habitat use of coral reef fish, the fatty acid composition and levels were examined in three species of parrotfish, Scarus psittacus: Scarus quoyi and Scarus rivulatus, which were collected at the Bidong Island of the Malaysian South China Sea. The proportions of saturated fatty acids (SAFA) are 57.6–64.9%, where fatty acids have the highest proportion, monounsaturated fatty acids (MUFA) (25.3–25.9%) have the second highest proport...

Significant genetic differentiation between the Yellow Sea and East China Sea populations of cocktail shrimp Trachypenaeus curvirostris revealed by the mitochondrial DNA COI gene
Publication date: April 2015 Source:Biochemical Systematics and Ecology, Volume 59 Author(s): Zhiqiang Han , Wenbin Zhu , Wei Zheng , Pengfei Li , Bonian Shui The cocktail shrimp Trachypenaeus curvirostris is an ecologically and economically important shrimp species in the Yellow Sea and East China Sea. However, there is no information about its population genetic structure. The population genetic structure and level of gene flow of T. curvirostris from the Yellow Sea and the East China Sea were studied with a 658-bp segment of mtDNA COI gene. In total, 85 individuals were collected from five locations and 13 haplotypes ...

Adaptive genetic variation in the smoke tree (Cotinus coggygria Scop.) is driven by precipitation
In this study, we selected Cotinus coggygria, which is widespread and locally adaptated species in China's warm-temperate zone, to investigate its landscape genetic pattern. We used eight microsatellite loci to examine the adaptive genetic variations of C. coggygria. A total of 43 microsatellite alleles were genotyped in 142 individual plants from 16 wild populations. The data demonstrated significant population differentiation within C. coggygria, which was caused by geographical distance, human activities, and precipitation. Five ecologically relevant microsatellite alleles, which were all related to the precipitation, w...
