Biochemical Systematics and Ecology (BIOCHEM SYST ECOL)
Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas:(i) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics);(ii) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology).Papers will be grouped in each issue according to subject area. Research papers should generally be of completed investigations. Preliminary reports will be published where findings are considered to be of sufficient interest to justify rapid publication. In addition, short reports of new sources of known compounds (New Source Reports) will be accepted where they can be justified in terms of systematic or ecological significance.

ABSTRACT: Phytochemical investigation of the leaves of Cecropia schreberiana Miq. (Urticaceae) led to the isolation of four triterpenoids (1-4), three flavone C-glycosides (5-7), two flavan-3-ols (8, 9), two flavanolignans (10, 11), and two proanthocyanidins (12, 13). All compounds were isolated from C. schreberiana for the first time. This is the first report demonstrating the presence of arjunolic acid (4), cinchonain Ia (10), and cinchonain Ib (11) in the Urticaceae family. The occurrence of flavanolignans within the family Urticaceae supports the likelihood that such compounds are more common within the class Magnoliopsida than previously thought.Biochemical Systematics and Ecology 06/2013; 48:96-99.

Article: Active constituents in Rheum acuminatum and Rheum australe (Polygonaceae) roots: A variation between cultivated and naturally growing plants[show abstract] [hide abstract]
ABSTRACT: The concentrations of five anthraquinones (chrysophanol, emodin, aloe-emodin, physcion and rhein) and two stilbenes (piceatannol and resveratrol) present in the roots of Rheum acuminatum and Rheum australe were determined and compared in cultivated and naturally grown plants. The roots of naturally grown plants used for experiments were collected from populations in the Gosaikunda area of Nepal, while artificially cultivated roots were grown in Průhonice in the Czech Republic. The extracts of powdered roots were analyzed using HPLC. Aloe-emodin and rhein were nearly absent in cultivated roots of both species, and the concentrations of emodin, physcion and chrysophanol were slightly higher in roots from natural habitats than from cultivated sites. Piceatannol and resveratrol were present in almost the same amounts in cultivated and natural samples from both species. Higher concentrations of emodin and physcion were present in R. acuminatum than in R. australe, while the opposite trend was observed for chrysophanol. The other compounds studied were equally common in both species. The results suggest that the two species could be used interchangeably. The cultivated plants can be used when high levels of piceatannol and resveratrol are desired, whereas plants from natural habitats can be used to obtain higher levels of the other compounds.Biochemical Systematics and Ecology 02/2013; 41:83–90.
Article: AFLP analysis of genetic variation in wild populations of five Rhododendron species in Qinling Mountain in China[show abstract] [hide abstract]
ABSTRACT: The genetic diversity in 22 populations of 5 wild Rhododendron species in Qinling Mountain in China was evaluated using amplified fragment length polymorphism (AFLP). Four AFLP selective primer combinations generated a total of 135 bands with their sizes ranging from 67 kb to 501 kb, among which 123 bands were found to be polymorphic, accounting for 92.04% variations. POPGENE analysis indicated that all the five species had high levels of genetic diversity, with percentage of polymorphic loci (PPL) ranging from 87.2 to 99.8% and effective number of alleles (ne) varying from 1.4205 to 1.9957. Shannon’s Information Index (I) differed from 0.4286 to 0.6921, while Nei’s gene diversity (H) varied from 0.2711 to 0.4989. The 5 species showed similar levels of genetic variations, with Hs and Ht ranging from 0.2253 to 0.4041 and from 0.2400 to 0.4994, respectively. The coefficient of gene differentiation among 22 populations (Gst) was 0.0923, accounting for 90.8% genetic diversity and only 9.2% genetic variations among the populations tested. The differences among populations were low in comparison with the previous studies on other species using the same technique. Low level of the genetic differences among Rhododendron populations investigated in the present study might be due to their outcrossing reproductive system. The analysis of molecular variance (AMOVA) also showed that variations among the species and populations were low, mainly due to a high variation within the populations. Based on unbiased genetic distances determined by an unweighted pair group method using arithmetic mean (UPGMA) phenogram, all populations could be grouped into Rhododendron species.Biochemical Systematics and Ecology 02/2013;

ABSTRACT: Abstract N-Acyl homoserine lactones (AHLs or N-AHLs) are a class of signaling molecules involved in bacterial quorum sensing (qs) that have recently been proposed as mediators of the fouling process. In this study, we determined the presence of AHLs in the following marine bacteria strains, which were collected in Santa Marta Bay (Colombia) from heavily fouled surfaces: Ochrobactrum sp., Vibrio sp. (23-6PIN), Vibrio campbellii, Vibrio sp. (11-6DEP), Ochrobactrum pseudogringnonense, Shewanella sp., Vibrio harveyi and Alteromonas sp. The detection and identification of AHLs was conducted using the microbial biosensor Escherichia coli (pSB401) and GC–MS and HPLC-MS analyses. We found that all isolated marine strains had quorum sensing systems mediated by either N-butanoyl homoserine lactone or N-hexanoyl homoserine lactone and in some cases by both. These results are in agreement with the theory that qs is involved in the fouling process. It is noteworthy to mention that we identified qs systems for the first time in bacteria of the genera Ochrobactrum and Alteromonas.Biochemical Systematics and Ecology 02/2013; 46:101.

Article: Low genetic diversity in marginal populations of Bletilla striata (Orchidaceae) in southern Korea: Insights into population history and implications for conservation[show abstract] [hide abstract]
ABSTRACT: The warm-temperate vegetation of Korea, currently limited to southern coastal areas, shifted southward during the Last Glacial Maximum towards glacial refugia putatively located in southern Japan and/or southern China. We hypothesized two scenarios of post-glacial re-colonization of warm-temperate species: (i) that extant Korean populations originated from a single source or (ii) that they are derived from multiple source populations. To test which of these scenarios is more likely, we investigated the patterns of genetic diversity in 16 populations of the warm-temperate terrestrial orchid Bletilla striata, employing 20 allozyme loci. Levels of genetic variation in B. striata were substantially lower than those reported in most other terrestrial orchids. However, the degree of genetic differentiation among populations was moderate. These results suggest a pattern of post-glacial re-colonization fitting the first scenario. Both in situ and ex situ conservation strategies are suggested to preserve the genetic variation of B. striata in Korea.Biochemical Systematics and Ecology 01/2013; 46:88-96.

ABSTRACT: A new secoiridoid glucoside, vinmajoroside (1), was isolated from the leaves of Vinca major L. along with 11 known compounds belonging to the secoiridoid ((7α)-7-O-methylmorroniside, 2), iridoid (loganin, loganic acid and 7-O-p-coumaroylloganin), monoterpenoid glucoindole alkaloid (5 (S)-5-carboxyvincoside and strictosamide), flavonoid (rutin, kaempferol 3-O-rutinoside and robinin), lignan (syringaresinol 4-O-β-glucopyranoside) and phenolic acid (chlorogenic acid) groups. The structure elucidation of the isolates was accomplished by extensive 1D and 2D-NMR experiments as well as ESI-MS. Secoiridoids and lignan were encountered for the first time in the genus VincaBiochemical Systematics and Ecology 01/2013; 49:69-72.
