The taxa of Scottish bracken in a European perspective

Summary

In contrast to the traditional view that Scottish Bracken (Pteridium Scop., Hypolepidaceae sensu Page, 1976) is a single, uniform taxon, evidence is presented that two species, each represented by multiple subspecies, are present in Scotland. These belong to two different species complexes within Pteridium, the P. aquilinum complex and the P. latiusculum complex. The P. aquilinum complex is represented by P. aquilinum (L.) Kuhn, with at least three subspecies: subsp. aquilinum, subsp. atlanticum C.N. Page and subsp. fulvum C.N. Page. The P. latiusculum complex is represented by P. pinetorum C.N. Page & R.R. Mill with at least two subspecies, subsp. pinetorum and subsp. osmundaceum (Christ) C.N. Page. Only P. aquilinum subsp. aquilinum is an aggressive weed which is a widespread problem to man; the others are rare. The paper establishes the nomenclatural priorities, typification, taxonomy, morphology, known distribution and ecology of all bracken taxa so far known from Scotland. The typification of P. aquilinum is discussed. There is no conflict between the two lectotypifications of Try on (1941) and Sheffield et al. (1989); both relate to the common bracken of the mid- and southern-latitudes of Europe, for which the existing epithet aquilinum must therefore be retained. It is pointed out that some of the other European taxa of bracken might well also yet be found within the British Isles, as well as, perhaps, other (especially possible diploid) taxa as yet undescribed.     

Typification of five names in Paracaryum (DC.) Boiss. (Boraginaceae)

Five names in the genus Paracaryum (DC.) Boiss. are lectotypified here: P. calycinum Boiss. & Bal. (endemic to Turkey), P. lithospermifolium (Lam.) Grande subsp. cariense (Boiss.) R. Mill var. cariense, P. kurdistanicum (Brand) R. Mill (endemic to Turkey), P. sintenisii Hausskn. ex Bornm., and P. strictum (C. Koch) Boiss.     

Shotgun Crystallization Strategy for Structural Genomics II: Crystallization Conditions that Produce High Resolution Structures for T. maritima Proteins

Currently, 119 high resolution structures of Thermotoga maritima proteins have been determined by the Joint Center for Structural Genomics (JCSG, www.jcsg.org). Sixty-seven of these were solved using the first implementation of the multi-tiered crystallization strategy at the JCSG for the efficient crystallization of large numbers of protein targets. Previously, we reported the analysis of all proteins crystallized using this multi-tiered strategy [Lesley, S.A. et al. (2002) Proc. Natl. Acad. Sci. USA 99, 11664–11669; Page, R. et al. (2003) Acta Crystallogr. D Biol. Crystallogr. 59, 1028–1037]. Here, we extend the analysis and describe the crystallization characteristics of those proteins that produced diffraction quality crystals, ultimately resulting in high resolution structures. First, we found that over 77% (52) of the crystals used for structure determination were produced directly from high-throughput coarse screens, indicating that less than one quarter of the crystals (15) required fine screening. In addition, as observed for the proteome screen [Page, R. et al. (2003) Acta Crystallogr. D Biol. Crystallogr. 59, 1028–1037], the majority of conditions that produced crystals for natively expressed proteins, whose structures have been determined, were distinct from those of their more extensively purified and selenomethionine-labeled counterparts. Finally, 99% of the proteins whose structures were solved crystallized in conditions contained in the JCSG Minimal Core Screen [Page, R. et al. (2003) Acta Crystallogr. D Biol. Crystallogr. 59, 1028–1037; Page, R. and Stevens, R.C. (2004) Methods 34, 373–389], a set of 67 conditions previously identified as those most likely to produce crystals of a diverse set of proteins, confirming its success for rapid identification of proteins with a natural propensity to crystallize.

Low structural diversity of the O-polysaccharides of Photorhabdus asymbiotica subspp. asymbiotica and australis and their similarity to the O-polysaccharides of taxonomically remote bacteria including Francisella tularensis

The O-polysaccharides were isolated from the lipopolysaccharides of emerging human pathogens Photorhabdus asymbiotica subsp. asymbiotica US-86 and US-87 and subsp. australis AU36, AU46, and AU92. Studies by sugar analysis and ¹H and ¹³C NMR spectroscopy before and after O-deacetylation showed that the O-polysaccharide structures are essentially identical within, and only slightly different between, the subspecies. The following structures of the repeating units of the O-polysaccharides were established:→3)-β-d-Quip4NGlyFo-(1→4)-α-d-GalpNAcAN3Ac-(1→4)-α-d-GalpNAcA3R-(1→3)-α-d-QuipNAc-(1→where GalNAcA stands for 2-acetamido-2-deoxygalacturonic acid, GalNAcAN for amide of GalNAcA, QuiNAc for 2-acetamido-2,6-dideoxyglucose, and Qui4NGlyFo for 4,6-dideoxy-4-(N-formylglycyl)aminoglucose; R = Ac in subsp. asymbiotica or H in subsp. australis. The structures established resemble those of a number of taxonomically remote bacteria including Francisella tularensis (Vinogradov, E. V.; Shashkov, A. S.; Knirel, Y. A.; Kochetkov, N. K.; Tochtamysheva, N. V.; Averin, S. P.; Goncharova, O. V.; Khlebnikov, V. S. Carbohydr. Res.1991, 214, 289–297), which differs in (i) the presence of a formyl group on Qui4N rather than the N-formylglycyl group, (ii) the mode of the linkage between the repeating units (β1→2 vs α1→3), (iii) amidation of both GalNAcA residues rather than one residue, and iv) the lack of O-acetylation.

The genus Bothriophoron (Stiles & Goldberger, 1910) Grétillat 1958 is synoymized with Calicophoron N?smark, 1937. Paramphistomum crassum Stiles & Goldberger, 1910, P. cauliorchis Stiles & Goldberger, 1910, P. ijimai Fukui, 1922, P. (Cauliorchis) skrjabini Popova, 1937, P. erschovi Davydova, 1959, Calicophoron orientalis Mukherjee, 1966, C. wuchengense Wang, 1979 and Cotylophoron skrjabini Mitskevich, 1958 in part are considered synonyms of Calicophoron calicophorum (Fischoeder, 1901) N?smark, 1937. C. zhejiangense Wang, 1979 is regarded a synonym of C. papillosum (Stiles & Goldberger, 1910) N?smark, 1937. P. vangrembergeni Van Strydonck, 1970 and P. togolense Albaret, Bayssade-Dufour, Guilhon, Kulo & Picot, 1978 are considered synonyms of Calicophoron phillerouxi (Dinnik, 1961) n. comb. and Ceylonocotyle petrovi Davydova, 1961 is synonymized with Calicophoron microbothrioides (Price & McIntosh, 1944) n. comb.

Stipa crassiculmis subsp. picentina (Poaceae) new for the Balkans – a further example of amphi-Adriatic disjunction

Stipa crassiculmis subsp. picentina Martinovský, Moraldo & Caputo (Poaceae, Pooideae, Stipae) was found for the first time in the Balkan Peninsula. It was recorded in the northern part of the Republic of Macedonia, in the P?inja River gorge (Badar Gorge), between Veles and Katlanovo on ultramafic substrates. To date, S. crassiculmis subsp. picentina was known only for Italy where it occurs in the Lombardy and Campania administrative regions. This record for the Balkan Peninsula is a new example of Amphi-Adriatic Balkan-Apennine disjunction. In this paper, the morphological and anatomical characters of the specimens collected in the study area were reported together with the phytosociological characteristics of the habitat. The threatened status of the species for Macedonia was also assessed on the basis of the IUCN criteria.

Cytogenetic effects of nine <Emphasis Type="Italic">Helichrysum</Emphasis> taxa in human lymphocytes culture

Helichrysum Mill. (Asteraceae) species have been used in folk medicine for thousands of years in the world. The in vitro cytogenetic effects in human lymphocytes of nine Helichrysum taxa used in Turkey folk medicine were investigated. Blood samples were obtained from healthy donors, non-smoking volunteers, which were incubated and exposed to increasing concentrations of methanol extracts of Helichrysum taxa (0.01, 0.05, 0.1, 0.5 and 1 mg/mL). The inhibitory effects of H. stoechas (L.) Moench subsp. barrelieri (Ten.) Nyman, H. armenium DC. subsp. armenium, H. armenium DC. subsp. araxinum (Kirp.) Takht., H. plicatum DC. subsp. plicatum, H. compactum Boiss. and H. artvinense P.H.Davis & Kupicha on the mitotic index and replication index indicate that these taxa can have genotoxic and mutagenic effects. They should therefore not be used freely in alternative medicine although their antiproliferative activity may suggest anticarcinogenic properties. Increase effects of H. stoechas subsp. barrelieri, H. armenium subsp. armenium, H. armenium subsp. araxinum, H. chasmolycicum P.H.Davis, H. plicatum subsp. plicatum, H. compactum and H. artvinense on the micronucleus rates showed that these taxa can have genotoxic and carcinogenic effects.     

Taxonomy of gastropods of the families Ranellidae (= Cymatiidae) and Bursidae. Part 2. Descriptions of 14 new modern Indo-West Pacific species and subspecies,with revisions of related taxa

Abstract

The subgenus Cymatium (Septa) is here restricted to species closely related to C. rubeculum (Linné, 1758). A lectotype is designated for C. rubeculum, neotypes are designated for C. hepaticum (Röding, 1798) and C. flaveolum (Röding, 1798), C. occidentale (Mörch, 1877) (= blacketi Iredale, 1936; = beui Garcia-Talavera, 1985) is recorded from the Indo-West Pacific, C. (Septa) marerubrum Garcia-Talavera, 1985 is ranked as a geographic subspecies of C. rubeculum, and three new taxa are named: C. (Septa) bibbeyi n. sp., Philippine Islands; C. (Septa) closeli n. sp., Indian Ocean; and C. (Septa) peasei n. sp., western Pacific. In the subgenus Cymatium (Ranularia), neotypes are designated for C. guttumium (Röding, 1798) and its synonyms, for C. moniliferum (A. Adams & Reeve, 1850), and for C. pyrulum (A. Adams & Reeve, 1850), a lectotype is designated for C. pseudopyrum (Martin, 1899) (a junior synonym of C. pyrulum), other species distinguished are C. encausticum (Reeve, 1844) and C. exile (Reeve, 1844), and new taxa named are C. andamanense n. sp., Andaman Islands, C. springsteeni n. sp., western Pacific and Red Sea, and C. sinense arthuri n. subsp., Red Sea. Other Ranellidae named are Sassia (Sassia) ponderi n. sp., Queensland, and Distorsio (Distorsio) euconstricta n. sp., Indian Ocean and southwest Pacific. A lectotype selected for Murex reticularis Linné, 1758 is a specimen of the species usually known as Distorsio reticulata (Röding, 1798).

In Bursa (Bursa), a lectotype is designated for B. grayana Dunker, 1862 (= B. bufoniopsis Maury, 1917; = B. pacamoni Matthews & Coelho, 1971), western Atlantic, and the similar new Oman to Philippines species B. davidboschi is named. Other Bursa taxa named are B. (Colubrellina) quirihorai n. sp., Philippines, and B. (Colubrellina) latitudo fosteri n. subsp., Philippines. In Bufonaria (Bufonaria), a lectotype designated for Murex rana Linné, 1758 confirms that as the name for the most common western Pacific species, a lectotype designated for Ranella crumena Lamarck, 1816 confirms that as the name for the most common Indian Ocean species, B. elegans (Beck in G. B. Sowerby II, 1836) is illustrated, and the new western Pacific species B. perelegans is named; the four similar species B. nobilis (Reeve, 1844), B. margaritula (Deshayes, 1832), B. gnorima (Melville, 1918), and B. thersites (Redfield, 1846) are distinguished, and the new Madagascar to Philippines species B. ignobilis is named. In Tutufa (Tutufella), the newly named species T. boholica occurs with T. rubeta (Linné, 1758) in deep water in the Philippine Islands.     

Taxonomic revision of the Koeleria splendens C. Presl group (Poaceae) in Italy based on morphological characters

Abstract

The Italian populations of Koeleria splendens C. Presl, critical group of the Mediterranean flora, are examined from the taxonomic and nomenclatural viewpoints. On the basis of literature data, herbarium investigations and field surveys, many morphologically well-differentiated taxa have been recognized. This group is widespread in the Italian peninsula and Sicily, where it is represented by the following units: K. splendens C. Presl, with four subspecies [subsp. splendens, subsp. grandiflora (Bertol. ex Schultes) Domin, subsp. brutia Brullo, Gangale & Uzunov, and subsp. ophiolitica subsp. nova], K. lucana sp. nova, K. subcaudata (Ascherson & Graebner) Ujhelyi, K. australis Kerner, K. callieri (Domin) Ujhelyi, and K. insubrica sp. nova. As concerns their distribution, both K. splendens and K. lucana are endemic to the Italian territory, while the other species occur also in some eastern Mediterranean countries. The taxonomic position of K. lobata, recently treated by some authors as a synonym of K. splendens, is also examined. A phylogenetic analysis was performed using morphological characters. Finally, a detailed iconography of the main morphological features and an analytical key of the Italian taxa (K. lobata included) are given.
