The first molecular analysis of samples collected in southern Backa (Serbia) confirmed the presence of aster yellows (16SrI) and stolbur phytoplasmas (16SrXII) in insects belonging to the family Cicadellidae, as well as in carrot plants where the insects were collected. A correct identification of the phytoplasmas and their vectors is essential to arrange effective control strategies to prevent diseases associated with phytoplasmas from spreading to carrots and other vegetable crops. In order to enhance knowledge about insect vectors of aster yellows and stolbur phytoplasmas in Serbia, Cicadellidae and Cixiidae (Homoptera Auchenorrhyncha), the most common vectors of these phytoplasmas, were monitored in southern Backa during 2008. Adults leaf- and planthoppers were collected and identified at species level using standard entomological methods, and tested for phytoplasma presence by means of PCR/RFLP. A total of 13 insect species of Cicadellidae were identified, as follows: a) three species of the subfamily Agallinae: Anaceratagallia ribauti (Ossiannilsson), Anaceratagallia venosa (Fourcroy), and Anaceratagallia laevis (Ribaut); b) seven species of the subfamily Deltocephalinae: Psammotettix confinis (Dahlbom), Psammotettix striatus (Linnaues) Psammottettix alienus (Dahlbom), Macrosteles sexnotatus (Fall?n), Ophiola decumana (Kontkanen), Errastunus ocellaris Fall?n, and Scaphoideus titanus Ball; c) three species of the subfamily Typhlocibinae: Eupteryx atropunctata (Goeze), Eupteryx mellissae Curtis, Zyginidia pullula (Boheman). Female specimens of the genus Euscelis (Deltocephalinae) were also collected, as well as one species of Reptalus quinquecostatus (Dufour) of the family Cixiidae. Stolbur phytoplasmas were detected in A. laevis, A. ribauti, A. venosa, P. striatus, P. confinis and P. alienus. The species: A. laevis, O. decumana, and P. confinis were AY-infected (subgroup 16SrI-A), while subgroup 16SrI-C was found only in one specimen of P. confinis. Since some aster yellows- and stolbur-infected species of the genera Psammotettix and Anaceratagallia (especially P. confinis and A. laevis) were regularly and commonly found in the infected carrot fields during the whole vegetative period, they could play a significant role in transmitting and spreading these pathogens in natural environment.

AbstractThe embryology of three polar flowering plants of the family Caryophyllaceae was studied using the methods and techniques of the light, normal and fluorescence microscopes, and the electron microscopes, scanning and transmission. The analyzed species wereColobanthus quitensisof West Antarctic (King George Island, South Shetlands Islands) as well asCerastium alpinumandSilene involucrataof the Arctic (Spitsbergen, Svalbard). In all evaluated species, flowering responses were adapted to the short Arctic and Australian summer, and adaptations to autogamy and anemogamy were also observed. The microsporangia of the analyzed plants produced small numbers of microspore mother cells that were differentiated into a dozen or dozens of trinucleate pollen grains. The majority of mature pollen grains remained inside microsporangia and germinated in the thecae. The monosporous Polygonum type (the most common type in angiosperms) of embryo sac development was observed in the studied species. The egg apparatus had an egg cell and two synergids with typical polarization. A well-developed filiform apparatus was differentiated in the micropylar end of the synergids. In mature diaspores of the analyzed plants of the family Caryophyllaceae, a large and peripherally located embryo was, in most part, adjacent to perisperm cells filled with reserve substances, whereas the radicle was surrounded by micropylar endosperm composed of a single layer of cells with thick, intensely stained cytoplasm, organelles and reserve substances. The testae of the analyzed plants were characterized by species-specific primary and secondary sculpture, and they contained large amounts of osmophilic material with varied density. Seeds ofC. quitensis,C. alpinumandS. involucrataare very small, light and compact shaped.

Aristolochic acids (AA) are phytochemicals found in plants of the genus Aristolochia belonging to the family Aristolochiaceae. These compounds bear a nitrophenanthrene carboxylic acid skeleton and are reported to be carcinogenic, mutagenic, and nephrotoxic. Sugar cane spirit infusions containing Aristolochia species are commonly used in Brazil as popular drinks, in total absence of scientific information. The presence aristolochic acids was confirmed in samples collected in popular markets of the city of Aracaju, Sergipe, Brazil. The aristolochic acids quantitative estimation was made in five samples of sugar cane spirit infusions obtained from different places of that city and were performed by high-performance liquid chromatography. The samples analyzed contained aristolochic acids I and II in concentrations ranging between 1.96 and 6.10 µg/ml for AA I and 2.22 and 11.55 µg/ml for AA II. The immediate banning of such popular drinks is recommended in view of the danger to ingest aristolochic acids, botanical products containing aristolochic acids or herbal products containing plants belonging to Aristolochiaceae family.

AbstractPlants produce phylogenetically and spatially restricted, as well as structurally diverse specialized metabolites via multistep metabolic pathways. Hallmarks of specialized metabolic evolution include enzymatic promiscuity, recruitment of primary metabolic enzymes and genomic clustering of pathway genes. Solanaceae plant glandular trichomes produce defensive acylsugars, with aliphatic sidechains that vary in length across the family. We describe a tomato gene cluster on chromosome 7 involved in medium chain acylsugar accumulation due to trichome specific acyl-CoA synthetase and enoyl-CoA hydratase genes. This cluster co-localizes with a tomato steroidal alkaloid gene cluster forming a ‘supercluster’, and is syntenic to a chromosome 12 region containing another acylsugar pathway gene. We reconstructed the evolutionary events leading to emergence of this gene cluster and found that its phylogenetic distribution correlates with medium chain acylsugar accumulation across the Solanaceae. This work reveals dynamics behind emergence of novel enzymes from primary metabolism, gene cluster evolution and cell-type specific metabolite diversity.

Abstract The quality of herbal products is important for ensuring efficacy and consumer safety. Traditional methods of authenticating herbs like ginseng via their morphology are hardly reliable. Different chemical constituents in herbs like ginseng tend to exhibit characteristic IR fingerprints that enable their identification. We previously introduced an IR-based protocol known as the 2-6PC rule to categorize and identify ginseng and its products, as well as distinguishing it from morphological fakes. Here, we describe the use of this rule as a rapid and effective means of analyzing the IR spectral fingerprints of the biologically active components of ginseng, as well as distinguishing among its species. Our results show that Panax ginseng, P. quinquefolius, and P. notoginseng can be differentiated from each other. Our results also indicate the presence of starch, carbohydrates, calcium oxalate, and ginsenosides Re and Rg1 in commercial ginseng roots sold in Singapore. This work effectively demonstrates the usefulness of the 2-6PC rule as a rapid screening tool in the authentication of ginseng species.
