Abstract Horseradish (Armoracia rusticana Gaertn., C.A. Mey & Scherb.) has a long history as food and medicinal plant. Glucosinolates (GLS) or their breakdown products are responsible for the pungent taste and claimed medicinal effects. The dominate GLS in horseradish is sinigrin (> 80%) followed by gluconasturtiin and glucobrassicin. A total of 168 Nordic accessions of horseradish were screened for the content of intact glucosinolates. Sinigrin levels varied between 10 and 45, gluconasturtiin between 1.3 and 7.4 and glucobrassicin between 0.1 and 2.6 μmol/g DM. Accessions with high levels of both sinigrin and gluconasturtiin were found. Horseradish accessions are kept as living plants in clonal archives in their respective countries. The task for plant gene banks is not only to conserve genetic resources for the future, but also to stimulate use of the collections for various products and breeding programmes. After further analyses to certify the screening results, selected accessions will form a base for breeding and increased use of horseradish as a condiment to food, natural preservative or in medical treatments

Modern breeding of sunflower (Helianthus annuus L.), which started 100 years ago, increased the number and the diversity of cultivated forms. In addition, for more than 50 years, wild sunflower and other Helianthus species have been collected in North America where they all originated. Collections of both cultivated and wild forms are maintained in gene banks in many countries where sunflower is an important crop, with some specificity according to the availability of germplasm and to local research and breeding programmes. Cultivated material includes land races, open pollinated varieties, synthetics and inbred lines. The majority of wild accessions are ecotypes of wild Helianthus annuus, but also 52 other species of Helianthus and a few related genera. The activities of three gene banks, in USA, France and Serbia, are described in detail, supplemented by data from seven other countries. Past and future uses of the genetic resources for environmental adaptation and breeding are discussed in relation to genomic and improved phenotypic knowledge of the cultivated and wild accessions available in the gene banks.

The indigenous knowledge of the Basotho makes it simple for this speech community to name their traditional medicinal plants in such a way that they are meaningful; this could also be viewed as an empowerment technique, especially in the economic sphere. Their medicinal plants names seem to be idiomatic and to express certain philosophies of the Basotho society. Creativity is observable in this kind of naming, and many names allude to the kind of remedy that is associated with the medicinal plant. It is therefore the interest of this paper to consider the names of medical plants among the Basotho whose names allude to the remedy they provide. The names of Sesotho medicinal plants and the reasoning of the Basotho in general behind the name and the use of each medicinal plant will be discussed in this article. This paper will further preserve and promote the use of Basotho traditional medicines for the future generation.

Abstract The structure of raspberry cultivars and genetic resources in the Baltic countries have been influenced by the historical political situation in the 20th century and climatic conditions, especially winterhardiness. The genetic resources consist of some old European and American cultivars, but mostly of cultivars and hybrids bred in Russia. Currently, targeted breeding programmes are active only in Estonia and Latvia, which aim to develop winterhardy, disease-resistant cultivars, well adapted to the local climate. Therefore, parent material for hybridisation has been chosen from local advanced hybrids and introduced cultivars suitable to the regional climatic conditions. The aim of the study was to estimate the level of genetic diversity of Rubus germplasm and assess inter-specific and intra-specific relationships using phenotypical characterisation and molecular markers. Forty one Rubus genotypes were evaluated by 41 phenotypical traits and 15 previously described SSR markers. Both characterisation approaches discovered high correspondence with pedigree and a low level of diversity. A limited amount of the diversity of raspberry genetic material has been used in various breeding programmes, despite their broad geographical origin. The obtained results indicate the need for including local wild R. idaeus plant material into breeding programmes.

Aim. To develop the National Plant Gene Pool Information System for the effective exchange of information and targeted use of this information in different research programs as well as for cooperation with regional and international organizations on the basis of intellectual property rights. Results and Discussion. This study was aimed at solving a set of interrelated objectives to compile a computer database of characteristics of the Global Collection of Agricultural Genetic Resources. The platform for this database was harmonized and systematized crop descriptors, which are the main component of the National Information System. As a part of these studies, the PGR Documentation Unit at the National Genebank of the Research Institute of Plant Genetic Resources worked at constructing data queries for presentation in the Information System forms. The tool part of the CAC-DB information system, where one can generate any query at one’s discretion by selecting data using the Query tools, served as a basis for this work. Seventeen types of queries for general use and 4 types of report templates were designed. The National Information System on Plant Genetic Resources, which is being developed at the Research Institute of Plant Genetic Resources, will make it possible to increase the efficiency of its storage, documentation, management and use through the exchange of information and germplasm, and will ensure the transition of genetic and breeding studies to a new technological level, increasing its effectiveness. Conclusions. The developed National Information System is unique and selective. It will concentrate comprehensive information on the plant gene pool of the Republic, as it is specific for Central Asia and the Southern Caucasus, having no analogues in the world.

Queer Persistence: On Death, History, and Longing for Endings

“What does it mean to live with HIV indefinitely, without knowing whether or not it will kill you?” Tim Dean writes, marking the changing timeline for HIV in the wake of new medical treatments. Exploring the anxiety experienced by some gay men as a result of the new uncertainties around HIV positivity, Dean proposes that this anxiety might tell all of us something about our relationships to time, the future, and mortality. Indeed, death has haunted queer theory from its inception as its implicit telos, either to be embraced or refused. But if death is the telos of queer theory, then it is one that repeatedly and frustratingly refuses to be final. This chapter explores the longing for endings and what might be called a "queer persistence" through Dean’s essay, Eve Sedgwick’s almost incidental description of queer as a “continuing moment,” and the Gospel of Mark, a text that bends or thwarts conventions of beginning, middle, and end. If anything worries us more than death, it seems, it is a lack of resolution.

Mineral concentration levels in cultivated vegetables have received very little concern in the context of biodiversity despite the fact that most vegetables have a rich micronutrient composition. Swiss chard is an important salad crop which is high yielding and rich in minerals, vitamins and phenolic compounds. It is also extremely easy to grow. However, there is a lack of information on the genetic variability of mineral concentration of Swiss chard. Mineral composition diversity of 54 genetically diverse Swiss chard accessions, representative of all Turkish Swiss chard genetic resources, was investigated using multivariate analysis. These traits are useful in evaluating germplasm diversity in the nutritional concentration context and for use in further breeding programmes which will focus on improving mineral concentrations in Swiss chard cultivars. The results displayed significant differences among accessions and remarkably high nutrient contents. The data gathered were analyzed using principal components (PCs) and cluster analysis and revealed five major groupings. The data also observed 74.39% of total variation. The first three PCs accounted for 49.86% of the total variation in the population. Present values provided great variability among accessions and the results demonstrate that it is possible to identify genetic differentiation among Swiss chard accession for some nutritional elements. The genetic resources that exist indicate that potentially important accessions could be used as a gene source due to their high levels of K, Ca, Cu and Zn in breeding programmes.
