Smells like debauchery: The chemical composition of semen-like, sweat-like and faintly foetid floral odours in Xysmalobium (Apocynaceae: Asclepiadoideae)
Publication date: June 2016 Source:Biochemical Systematics and Ecology, Volume 66 Author(s): Adam Shuttleworth Floral volatiles play an important role in plant communication with both pollinators and antagonists, but remain poorly explored for many plant groups. Asclepiads (Apocynaceae: Asclepiadoideae subtribe Asclepiadinae) represent a diverse group in South African grasslands, but the scents of most species remain unexplored and few genera are sufficiently sampled to allow comparisons between congeners.

Genetic variation and phylogenetic relationships among Rehmannia (Scrophulariaceae) species as revealed by a novel set of single-copy nuclear gene markers
In this study, genetic variation and interspecific relationships in the genus Rehmannia were investigated by a novel set of SCNG markers. In total, 12 pairs of primers were successfully amplified and sequenced in six Rehmannia species after screening 258 candidate genes from the transcriptome datasets of Rehmannia glutinosa. The moderate to high level of nucleotide polymorphisms were identified in these SCNG markers, and nucleotide diversity (π) per locus ranged from 0.00498 to 0.01100, with 6–10 haplotypes. R. chingii and R. piasezkii exhibited a high level of genetic variation, while R. glutinosa and R. solanifo...

Chemotype A contained anagyrine, a potent teratogen in cattle, and thus would pose a risk to cause crooked calf syndrome in grazing cattle, while Chemotype B did not contain anagyrine and poses no teratogenic risk. No alkaloids were detected in the L. polyphyllus plants collected in this area. Phylogenetic analysis showed th...

Simulation and prediction of nitrous oxide emission by the water and nitrogen management model on the Tibetan plateau
Publication date: April 2016 Source:Biochemical Systematics and Ecology, Volume 65 Author(s): Yangong Du, Xiaowei Guo, Guangmin Cao, Bin Wang, Guoyan Pan, De Li Liu Process-based simulation models have been used to assess the characteristics of N2O emission and to examine the potential impacts of climate change in grassland ecosystems. Temporal N2O fluxes from the soil–atmosphere interface were monitored in this study continuously for two years by using flux chamber measurements and were simulated by using the water and nitrogen management model (WNMM_NSWDPI version) on the Tibetan plateau. The model predicti...

Molecular systematics of genus Bulbophyllum (Orchidaceae) in Peninsular Malaysia based on combined nuclear and plastid DNA sequences
Publication date: April 2016 Source:Biochemical Systematics and Ecology, Volume 65 Author(s): Shahla Hosseini, Kourosh Dadkhah, Rusea Go Phylogenetic relationships were inferred for representative Bulbophyllum species of 13 sections from subtribe Bulbophyllinae (Epidendroideae, Orchidaceae) in Peninsular Malaysia. The combined data matrix consists of sequences from ITS nuclear gene region and trnL-F, matK, and rbcL plastid gene regions with 3114 characters. Molecular data were analysed using parsimony and Bayesian inference. The results show that several recognized sections are monophyletic. Section Hirtula with parap...

Participation of the enzymes involved in the biosynthesis of biogenic amines in biochemical interactions between wheat (Triticum aestivum; Poaceae) and bird cherry-oat aphid (Rhopalosiphum padi; Aphididae)
Publication date: April 2016 Source:Biochemical Systematics and Ecology, Volume 65 Author(s): Cezary Sempruch, Bogumił Leszczyński, Martyna Wilczewska, Hubert Sytykiewicz, Paweł Czerniewicz, Sylwia Goławska, Grzegorz Chrzanowski, Henryk Matok The studies concerned changes in the activities of ornithine decarboxylase (ODC), lysine decarboxylase (LDC) and tyrosine decarboxylase (TyDC) in tissues of wheat (Triticum aestivum L.) infested with bird cherry-oat aphid (Rhopalosiphum padi L.). Obtained results showed that the activities of the enzymes were stimulated in the less susceptible wheat Kontesa cv. infested ...

Genetic variation in a freshwater prawn species, Palaemon paucidens, in South Korea
In this study, we investigated the geographical distribution of genetic variation and the genetic structure of P. paucidens populations using mitochondrial DNA sequences and genotypes identified from four microsatellite loci. Our results showed that populations from westward-flowing river systems that drain into the Yellow Sea have more genetic diversity than those from southward-flowing river systems, and that the highest genetic variance revealed by analysis of molecular variance (AMOVA) using both genetic markers was observed in river systems grouped as HAN + GEUM, NAKDONG + JEJU, YOUNGSAN, and SEOMJ...

A new acetylated spirostanol saponin and other constituents from the rhizomes of Dioscorea althaeoides R. Knuth (Dioscoreaceae)
Publication date: April 2016 Source:Biochemical Systematics and Ecology, Volume 65 Author(s): Xuejiao Li, Songsong Jing, Shuli Man, Xia Li, Chengcheng Zhao, Ying Wang, Wenyuan Gao A new acetylated spirostanol saponin (7), dioscin-6′-O-acetate, was isolated from the rhizomes of Dioscorea althaeoides R. Knuth (Dioscoreaceae), together with fourteen known compounds, including three spirostanol saponins (1–2, 6), three furostanol saponins (10–12), one diarylheptanoid (3), three sterols (4–5, 9), three aliphatic acids (8, 13–14) and one aliphatic alkane (15). Their structures were establis...

Phenotypic and genotypic intra-diversity among Anatolian durum wheat “Kunduru” landraces
This study showed that Kunduru landraces maintains high allelic variation. PCoA indicated that eco-geographical variables have a significant effect on SSR diversity as well as morphological traits. Many of the landraces studied are in danger of disappearing from the local farmers' fields; this study demonstrates the importance of maintaining and conserving this precious genetic resources.

Amplified fragment length polymorphism analysis of the population structure and genetic diversity of Phoebe zhennan (Lauraceae), a native species to China
In this study, we used 12 amplified fragment length polymorphism primer combinations to assay 92 accessions, which were highly representative of the entire P. zhennan germplasm. It revealed that P. zhennan consisted of three genetic populations, named as SCZ (central Sichuan), CQH (eastern Sichuan, Chongqin, Hubei and Hunan) and YG (Yunnan and Guizhou), probably owing to natural selection caused by topography differences. The CQH population further diverged into two geographical sub-populations: CD-CQ (SCD and west region of Chongqin) and HB-HN (eastern side of Chongqin, Hubei and Hunan). The loci were moderately polymorph...

Phylogenetic relationships and natural hybridization in Triadica inferred from nuclear and chloroplast DNA analyses
In this study, we sequenced the nrITS regions, two nuclear genes and a chloroplast gene to reconstruct the molecular phylogeny of Triadica and to test the hypothesis of natural hybridization between Triadica sebifera and Triadica cochinchinensis, and between T. sebifera and Tridica rotundifolia. Phylogenetic analysis showed that T. sebifera diverged first within this genus, and T. cochinchinensis and T. rotundifolia were sister species. Both of the two putative hybrids show chromatogram additivity at each of the two nuclear genes, providing convincing evidence for natural hybridization between T. sebifera and T. cochinchin...

Groenewald, William A. Haddad, Marie-Pierre Dubois, Bettine Jansen van Vuuren Twenty-one microsatellite locus were characterized for the collembolan Cryptopygus antarcticus travei (Deharveng, 1981) of the sub-Antarctic Marion Island of South Africa. For the analyzed samples (67 individuals distributed in 19 populations), we observed an average of 7.2 alleles per locus, an observed and expected heterozygosity ra...
