Accepted 6 June, 2012 Analysis of karyotype, nucleic deoxyribonucleic acid (DNA) content and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) were performed in Zantedeschia aethiopica and Zantedeschia elliottiana. Mitotic metaphase in both species showed 2n=32. The chromosomes of both species were quite similar with medium length ranging from 1.55 ± 0.04 to 3.85 ± 0.12 µM in Z. aethiopica and 2.15 ± 0.04 to 3.90 ± 0.12 µM in Z. elliottiana. However, some differences were found in morphology and centromeric position among the chromosomes. Identification of individual chromosomes was carried out using chromosomes length, and centromeric positions. The karyotype of Z. aethiopica was determined to be 2n = 32 = 14 m + 18 sm and of Z. elliottiana to be 2n = 32 = 10 m + 22 sm. The 2C nuclear DNA content was found to be 3.72 ± 0.10 picograms (equivalent to 3638.16 mega base pairs) for Z. aethiopica and 1144.26 ± 0.05 picograms (equivalent to 1144.26 mega base pairs) for Z. -

African Journal of Biotechnology Vol. 10(48), pp. 9800-9803, 29 August, 2011 Available online at http://www.academicjournals.org/AJB ISSN 1684–5315 © 2011 Academic Journals Full Length Research Paper Nature of ergastic substances in some Poaceae seeds Idu, M. 1* and Onyibe, H. I. 2 1Department of Botany, University of Benin, PMB 1154, Benin City, Edo State, Nigeria. 2Department of Botany, Ambrose Alli University, PMB. 14, Ekpoma, Edo State, Nigeria. Accepted 6 May, 2011 Seeds of 48 species of Poaceae were examined for the presence of alkaloid, protein, fats and oil, inulin, starch and tannins. All taxa investigated indicated the presence of starch, fats and oils and protein and were devoid of tannins and inulin. Only 12 seed samples indicated the presence of alkaloids. The Positively indicated taxa are suggested for further investigation. Key words: Poaceae, starch, fats and oils, alkaloid, protein, tannins, inulin. INTRODUCTION Ergastic substances are products of metabolism. These reserve (Abelson, 1978). substances may appear or disappear at different times in From the beginning, seeds have been and still are the the life of the cell. They are reserve or waste products main source of man’s diet. The Poaceae (large seeded resulting from cellular activities. Some well-known grasses) contribute more food seeds than any other plant ergastic substances are carbohydrates, cellulose and family; it contributes about 50% per capita energy intake starch, protein bodies, fats and related substances (FAD, 1977). (Eckey, 1954; Pritchard, 1997; Arahira et al., 1998; The importance of the nature of ergastic substances in Christina et al., 2001; Gómez-Sosa and Castro, 2004; plant taxonomy has been stressed by various authors Wolf, 2006). -
Central European Vegetation
Plant Formations in the Central European BioProvince Peter Martin Rhind Central European Beech Woodlands Beech (Fagus sylvatica) woods form the natural climax over much of Central Europe where the soils are relatively dry and can extend well into the uplands in the more southern zones. In the north, however, around Sweden it is confined to the lowlands. Beech woodlands are often open with a poorly developed shrub layer, Characteristic ground layer species may include various helleborines such as Cephalanthera damasonium, C. longifolia and C. rubra and sedges such as Carex alba, whilst in others, grasses like Sesleria caerlea or Melica uniflora may predominate, but in some of the more acidic examples, Luzula luzuloides is likely to dominate. There are also a number of endemic ground layer species. For example, in Carpathian beech woods endemics such as Dentaria glandulosa (Brassicaceae), Symphytum cordata (Boraginaceae) and the fern Polystichum braunii (Dryopteridaceae) may be encountered. Fine examples of primeaval beech woods can be found in the limestone Alps of lower Austria including the famous ‘Rothwald’ on the southeastern slopes of Dürrentein near Lunz. These range in altitude from about 940-1480 m. Here the canopy is dominated by Fagus sylvatica together with Acer pseudoplatanus, Picea abies, Ulmus glabra, and on the more acidic soils by Abies alba. Typical shrubs include Daphne mezereum, Lonicera alpigena and Rubus hirtus. At ground level the herb layer is very rich supporting possibly up to a 100 species of vascular plants. Examples include Adenostyles alliariae, Asplenium viridis, Campanula scheuchzeri, Cardamine trifolia, Cicerbita alpina, Denteria enneaphyllos, Euphorbia amygdaloides, Galium austriacum, Homogyne alpina, Lycopodium annotinum, Mycelis muralis, Paris quadrifolia, Phyteuma spicata, Prenanthes purpurea, Senecio fuchsii, Valeriana tripteris, Veratrum album and the central European endemic Helliborus niger (Ranunculaceae). -

Anthropogenic N deposition increases soil C storage by reducing the relative abundance of lignolytic fungi. Elizabeth M. Entwistle, Donald R. Zak, and William A. Argiroff. Ecological Monographs. APPENDIX S3 Table S1. Agaricomycete taxa excluded from our list of “highly lignolytic taxa”. We excluded any classes, families, or genera: 1) that are known to be (largely or entirely) comprised of non-saprotrophs or for which the nutritional modes are unknown, 2) for which we have no information regarding a role in lignin decay, 3) for which there is published evidence that the taxon is either nonlignolytic or weakly lignolytic, 4) that are or may be lignolytic, but for which there is insufficient evidence that they are highly lignolytic, 5) for which existing evidence regarding their capacity to decay lignin is contradictory, 6) that are represented in our data set by fewer than 20 sequences regardless of their physiology, 7) that were “unclassified” at the order or class level (most not shown below), 8) that were “unclassified” at the genus level (not shown below) and did not belong to families selected as “highly lignolytic taxa” (see Table S2).

The sequenced loci included rDNA ITS, partial chitin synthase gene (CHS1), as well as fragments of two unnamed orthologous genes (Bgt-1929, Bgt-4572). The combined evidence led to a reassessment and a new neotypification of B. graminis s. str. (emend.), and the description of seven additional species, viz. B. americana sp. nov. (mainly on hosts of the Triticeae), B. avenae sp. nov. (on Avena spp.), B. bromi-cathartici sp. nov. (on Bromus catharticus), B. bulbigera comb. nov. (on Bromus spp.), B. dactylidis sp. nov.

Bocconea 25, Results of the Seventh Iter Mediterraneum
Bocconea 25: 5-127 doi: 10.7320/Bocc25.005 Version of Record published online on 9 July 2012 Werner Greuter Results of the Seventh “Iter Mediterraneum” in the Peloponnese, Greece, May to June 1995 (Occasional Papers from the Herbarium Greuter – N° 1) Abstract Greuter, W.: Results of the Seventh “Iter Mediterraneum” in the Peloponnese, Greece, May to June 1995. (Occasional Papers from the Herbarium Greuter – N° 1). — Bocconea. 25: 5-127. 2012. — ISSN 1120-4060 (print), 2280-3882 (online). The material collected during OPTIMA’s Iter Mediterraneum VII to the Peloponnese in 1995 has been revised. It comprises 2708 gatherings, each with 0 to 31 duplicates, collected in 53 numbered localities. The number of taxa (species or subspecies) represented is 1078. As many of the areas visited had been poorly explored before, a dozen of the taxa collected turned out to not to have been previously described, of which 9 (7 species, 2 subspecies) are described and named here (three more were published independently in the intervening years). They belong to the genera Allium, Asperula, Ballota, Klasea, Lolium, Minuartia, Nepeta, Oenanthe, and Trifolium. New combinations at the rank of subspecies (3) and variety (2) are also published. One of the species (Euphorbia aulacosperma) is first recorded for Europe, and several are new for the Peloponnese or had their known range of distribution significantly expanded. Critical notes draw attention to these cases and to taxonomic problems yet to be solved. An overview of the 11 Itinera Mediterranea that have taken place so far is presented, summarising their main results. Keywords: Flora of Greece, Peloponnese, Itinera Mediterranea, OPTIMA, new species, new com- binations, Allium, Asperula, Ballota, Klasea, Lolium, Minuartia, Nepeta, Oenanthe, Trifolium. -
Beckmannia Eruciformis (L.) Host in Slovakia – Distribution, Ecology and Coenotic Affinity Dedicated to the Memory of Ján Bogoly (1951 – 2011)
HACQUETIA 10/2 • 2011, 171–181 DOI: 10.2478/v10028-011-0009-3 Beckmannia eruciformis (L.) Host In SlovAKIA – dIstrIbutIon, ecoLogy And coenotIc AffInIty Dedicated to the memory of Ján Bogoly (1951 – 2011) Daniel DÍTĚ1, Pavol ELIÁŠ jun.2, Richard HRIVNÁK1 & Zuzana MELEČKOVÁ1 Abstract The historical and recent distribution, ecology and phytosociology of perennial grass Beckmannia eruciformis was studied in Slovakia between 2002 and 2010. Altogether 22 natural and two secondary sites with presence of the species were found from published sources, herbaria and field research. Localities of its native occur- rence have been concentrated in Eastern Slovakia (Východoslovenská nížina Lowland from the settlement of Streda nad Bodrogom to the villages of Pribeník and Biel). Secondary sites were found in Western Slovakia (Podunajská nížina Lowland; the surroundings of Sládkovičovo town and Jaslovské Bohunice village). The relatively massive reduction of Beckmannia eruciformis localities was recorded in the seventies and eighties of the last century; it was related to massive land reclamation and alterations in the water regime of river alluvia. Recently only seven localities were found. Permanent occurrence was confirmed only in two localities (Malý Horeš, Strážne). In those cases Beckmannia eruciformis has created relatively large populations including some thousands of individuals. All other recent occurrences were temporary (Streda nad Bodrogom, Keresztúr farmstead, Horešské lúky Nature Reserve, Veľký Horeš, Pribeník). Moreover, they were relatively poor in the number in individuals and are acutely threatened by anthropogenic changes of environmental condi- tions. According to our results and by applying the IUCN criteria, we propose to modify the threat category of the species from critically endangered (CR) to endangered (EN) in Slovakia. -

New Records of Basidiomycetes from the Pskov Region in the Polistovskiy State Nature Reserve (Russia)
Nature Conservation Research. Заповедная наука 2020. 5(3): 9–22 https://dx.doi.org/10.24189/ncr.2020.024 NEW RECORDS OF BASIDIOMYCETES FROM THE PSKOV REGION IN THE POLISTOVSKIY STATE NATURE RESERVE (RUSSIA) Lyudmila B. Kalinina1,*, Sergey Yu. Bolshakov1, Tatiana M. Bulyonkova2 1Komarov Botanical Institute of RAS, Russia 2Ershov Institute of Informatics Systems, SB RAS, Russia *e-mail: [email protected] Received: 07.02.2020. Revised: 29.04.2020. Accepted: 30.04.2020. Prior to a present paper, 918 species of basidiomycete fungi were known in the Pskov region (Russia), including 512 species recorded in the Sebezhskiy National Park. Fungal inventorying studies in Protected Areas are an important part of biodiversity assessment. The constantly expanding knowledge on this vast group of organisms, powered by new finds in the field and advances in molecular genetics, make fungal inventorying in any territory a long-term effort rather than an isolated event. In 2019, we assessed the fungal biota of the Polistovskiy State Nature Reserve (Pskov region, Russia) in various forest types in the core and buffer zones along nine designated routes. The material was studied using the standard methods of fungal taxonomy. As a result, 74 basidomycete species new to Pskov region were revealed. Among them, six species (Galerina hybrida, Gymnopus erythropus, Lepiota boudieri, Pluteus velutinus, Rugosomyces obscurissimus, and Simocybe haustellaris) were new to the Northwest of European Russia and four species (Achroomyces effusus, Botryobasidium stigmatisporum, Gale- rina caulocystidiata, and Pseudobaeospora celluloderma) were new for Russia. The former are here provided with brief notes, whereas the latter are supplied with descriptions of studied specimens, drawings of micro- structures and discussion of their distribution, habitats, similar and closely related species, and current state of knowledge. -
