Genome-wide identification and characterization of the WRKY gene family in potato (Solanum tuberosum)
This study aimed to develop a complete overview of the WRKY family by using the potato genome.

Phylogenetic relationships of the Chalcides skink species from the Chafarinas Islands with those from mainland North Africa
We report a phylogenetic mitochondrial DNA analysis comparing the populations of the three Chalcides skink species from the Chafarinas Islands (NW Africa) with specimens of the same species from the nearest mainland. We tested for the potential genetic distinctiveness of the skink island populations. However, the results of the comparison of the genetic variability of the mitochondrial coding gene cytb were conclusive showing that the genetic divergence between continental and island Chalcides species was either non-existent or extremely low. We discuss how genetic divergence may be lower than expected if separation time o...

Genetic diversity and population structure of Korean wild soybean (Glycine soja Sieb. and Zucc.) inferred from microsatellite markers
In this study, the genetic diversity of 100 mainland Korean wild soybean accessions was evaluated by using 42 simple sequence repeat markers covering 17 soybean chromosomes. All analyzed loci were polymorphic and a total of 114 alleles were found. The observed average genetic diversity was low (0.4). The results showed that the 100 selected accessions did not exactly follow the geographical distribution. These results were further confirmed by the phylogeny inferred from five morphological characteristics (i.e., leaf shape, leaf area, plant shape, seed area, and 100-seed weight).

Complete mitochondrial genome of Neochauliodes parasparsus (Megaloptera: Corydalidae) with phylogenetic consideration
Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Yanyu Zhao, Hongli Zhang, Yanhua Zhang We sequenced the complete mitochondrial genome (mitogenome) of Neochauliodes parasparsus. The 15,995-bp mitogenome contained the standard set of 13 protein-coding genes, 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and a putative control region, with a gene arrangement that was identical to that reported for most other megalopteran species. We also predicted the secondary structure of all the RNA genes and analysed the preferred codon usage of the protein-coding genes. Th...

Chemical study of Anthospermum emirnense (Rubiaceae)
Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Tiana Sylvia Ralambonirina Rasoarivelo, Raphaël Grougnet, Sylvie Michel, Christiane Rakotobe Guillou, Brigitte Deguin Chemical study of the aerial parts of Anthospermum emirnense led to the isolation of one original iridoid glycoside (1) along with six known iridoids (2–7), three lignans (8–10), two flavonoids (11–12), one coumarin (13), two anthraquinones (14–15), two benzoic acids (16–17) and three triterpenoids (18–20). These results are the first chemical data on non-volatile consti...

ITS2 barcode for identifying the officinal rhubarb source plants from its adulterants
Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Yun Zhou, Xiao-Lei Du, Xin Zheng, Min Huang, Yan Li, Xu-Mei Wang Officinal rhubarb, the dried root and rhizome of Rheum officinale Baill., Rh. palmatum L., and Rh. tanguticum (Maxim. ex Regel) Maxim. ex Balf. of Polygonaceae family, is one of the most well-known and important traditional Chinese medicines. The growing herbal market has led to the introduction of adulterants, and difficulties in morphological based discrimination has also resulted in concerns over consumer safety. ITS2 as a potential barcode was employed to dis...

Genome origin and phylogenetic relationships of Elymus villosus (Triticeae: Poaceae) based on single-copy nuclear Acc1, Pgk1, DMC1 and chloroplast trnL-F sequences
Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Chao Tang, Jie Qi, Ning Chen, Li-Na Sha, Yi Wang, Jian Zeng, Hou-Yang Kang, Hai-Qin Zhang, Yong-Hong Zhou, Xing Fan To investigate the genome origin and phylogenetic relationships of Elymus villosus, three single-copy nuclear gene (Acc1, Pgk1 and DMC1) and chloroplast trnL-F gene sequences of two accessions of E. villosus were analyzed with those of eighteen allotetraploids (StH, StY, StP and StEe genomes) and thirty-five diploid taxa representing eighteen basic genomes in Triticeae. The results revealed that: (1) the genomic ...

Secondary metabolites from Ajania salicifolia and their chemotaxonomic significance
Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Zhuan-Ning Shi, Hong-Ru Wu, Xiao-Yan Pang, Jing-Rong Chen, Ying Zhu Forty-seven secondary metabolites were isolated from Ajania salicifolia (Mattf.) Poljak, including eight sesquiterpenoids, two diterpenoids, three triterpenoids, four steroids, three flavonoids, five coumarins, five lignans, nine phenylpropanoids, five other phenolic compounds, and three acetylenes. Their chemotaxonomic significance within the genus Ajania (the tribe Anthemideae) of the family Asteraceae is discussed. (Source: Biochemical Systematics and Ecology)

Variation in essential oil composition of Leonotis leonurus, an important medicinal plant in South Africa
Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Baudry N. Nsuala, Guy P. Kamatou, Maxleene Sandasi, Gill Enslin, Alvaro Viljoen Leonotis leonurus widely used by traditional healers in southern Africa for treatment of various ailments, is well known for its reported psychoactive properties. The present study was undertaken to investigate the variation in essential oil composition between geographically distinct populations of L. leonurus in South Africa using gas chromatography. Plant material (n = 50) was collected from three provinces of South Africa. Essential o...

The complete mitochondrial genome of Tonkinacris sinensis(Orthoptera: Acrididae): A tRNA-like sequence and its implications for phylogeny
Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Xinmei Zhang, Xuejuan Li, Fei Liu, Hao Yuan, Yuan Huang The complete mitochondrial genome of Tonkinacris sinensis is 15,627 bp long and contains13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes and one A + T-rich region. The gene order and orientation are identical to those of other Orthoptera species, containing the rearrangement of trnD and trnK. Intriguingly, a tRNASer-like gene exists on the N strand between the trnSUCN and nad1 genes. The length of this gene is 110 bp, and it has a typical clover-leaf ...

Parallel evolution evidenced by molecular data in the banded-tetra (Astyanax fasciatus)
Publication date: February 2017 Source:Biochemical Systematics and Ecology, Volume 70 Author(s): Rubens Pazza, Letícia Aparecida Cruvinel, Karine Frehner Kavalco Astyanax is well known as a model for developmental biology studies, particularly with regard to Mexico's cave populations. More than 130 species of Astyanax are already known, most of which live in South America. The occurrence of cryptic species and species complexes elucidated by chromosomal and genetic studies demonstrates that the relationship between morphology and molecular evolution is quite complex within this group. In this work, we demonstrate t...
