Birdsfoot trefoil (Lotus corniculatus L.) is a highly variable and widely distributed Old World perennial forage legume found in wild and naturalized populations
throughout temperate regions of Europe, Asia Minor, North Africa, North and South America, Australia, and New Zealand. Understanding
the relationships among birdsfoot trefoil morphological, ecogeographic and chemical characteristics may provide insights for
better utilizing of exotic germplasms. Ten birdsfoot trefoil populations were and sampled and determined in Serbia and Bosnia
and Herzegovina. Some morphological properties, such as growth form of populations, flower color, flowering period, number
of stems, length of main stem, number of racemes per stem, number of flowers per inflorescence, number of pods per racemes,
number of seeds per pods, hard seeds in the first year, dry matter (DM) yield, and some chemical properties, such as content
of crude protein, ash, fat, crude fiber, phosphorus, calcium, magnesium, potassium, K/(Ca+Mg) ratio, and sulfur, manganese,
iron, copper, zinc, selenium and tannin contents, were determined in all populations. Serbia is an important origin center
of genes for many legume species. Considering the high values of their traits, some Serbian trefoil populations could serve
as a valuable breeding material. In comparison with populations from other parts of the world, Serbian populations are superior
in chemical properties and nutritional quality values. The investigated populations clustered in two distinct groups according
to the analyzed characteristics. 相似文献

Staff members of the Department of Botany of Palacký University in Olomouc and Gene Bank Department – Workplace Olomouc, Research Institute of Crop Production in Prague, Czech Republic, conducted an expedition in seven European countries (Austria, Czech Republic, France, Germany, Italy, the Netherlands, Switzerland) in August/September 1999 to collect wild Lactuca spp. germplasm and study its geographic distribution, ecology and biodiversity. During the mission, more than 600 locations were visited resulting in the collection of 602 seed samples (accessions) of wild Lactuca species and 13 seed samples of related genera (Chondrilla and Mycelis). Lactuca serriola f. serriola, L. serriola f. integrifolia, L. saligna and L. viminea subsp. chondrilliflora were prevalent in southern Europe (Italy, France), however, only L. serriola was common in central and western Europe (Austria, Czech Republic, Germany, Netherlands, Switzerland). The greatest diversity of Lactuca species was found in France, where also the most seed samples (165) were collected. The most characteristic habitats with a high density of Lactuca spp. populations were observed along roads and highways, grassy ditches, ruderal communities, and dust-heaps. Natural infections by powdery mildew (Erysiphe cichoracearum) and downy mildew (Bremia lactucae) on some wild Lactuca spp. were observed. Recent observations concerning the geographic distribution, population structure, habitats, and natural occurrence of diseases of Lactuca spp. are discussed. This assemblage of genetic resources of Lactuca spp. can serve as the basis of future studies of species diversification, spatial population structure, plant microevolution, domestication processes, and genetic variability of host-parasite interactions. 相似文献

Random-amplified polymorphic DNA (RAPD) markers were used to evaluate genetic variability among populations of an Italian
strawberry ecotype, and to determinate genetic relationships between genotypes and their putative ancestor. A total of 65
selections and one cultivar ‘Madame Moutot’ (MM), were analysed to evaluate genetic variability present in Etna mountain area
and to confirm as MM was one of the cultivars that originated the ecotype. A total of 222 RAPD markers was obtained using
16 decamer primers and 6 longer primers, 90.8% of the markers obtained by selected primers resulted polymorphic at least within
analysed genotypes. RAPDs were used to calculate genetic similarity coefficients and to generate dendrograms representing
genetic relationships among genotypes analysed. Cluster analysis displays as RAPD polymorphisms were able to characterize
the genotype variability among closely related groups. The data show as MM could be considered the ancestral genotypes introduced
in that area. The results obtained confirm that RAPD markers could be used as reliable markers to perform phylogenetic studies
in Fragaria×ananassa Duch. ex Rozier.

Indirect somatic embryogenesis is effective at eliminating the most important viruses affecting grapevines. Accordingly, this
technique was tested as a method for eradicating two widespread viroids, Grapevine yellow speckle viroid 1 (GYSVd-1) and Hop stunt viroid (HSVd), from four grapevine cultivars. Both viroids were detected by RT-PCR in grapevine floral explants used for initiating
embryogenic cultures, as well as in undifferentiated cells of embryogenic and non-embryogenic calli from anthers and ovaries.
In contrast, somatic embryos differentiated from these infected calli were viroid-free, and viroids were not detected in embryo-derived
plantlets even 3 years after their transfer to greenhouse conditions. A wider spatial distribution of HSVd than GYSVd-1 within
proliferating calli was revealed by in situ hybridization, whereas no hybridization signal was detected in the somatic embryos.
In addition, GYSVd-1 and HSVd were localised in the nucleus of infected cells, conclusively showing the nuclear accumulation
of representative members of Apscaviroid and Hostuviroid genera, which has been only an assumption so far. Somatic embryogenesis was compared to in vitro thermotherapy, a technique
routinely used for virus eradication. After thermotherapy, HSVd and GYSVd-1 were detected in all in vitro plantlets of the
cultivar Roussan, and in all lines analysed after 3 years of culture in greenhouse. The high efficiency with which somatic
embryogenesis may eliminate viroids and viruses from several infected grapevine cultivars, should allow the availability of
virus- and viroid-free material, which would be useful not only for sanitary selection but also for basic research on plant-virus
and plant-viroid interactions in grapevine. 相似文献

Purpose
The influence of bone sorbent addition onto distribution of 90Sr in artificially contaminated soil was preliminary studied to assess the possibility of biogenic apatite utilization for reduction of 90Sr mobility and availability. Simultaneously, the disruption of soil micro- (Cd, Zn, Co, Cu, Cr, and Ni,) and macroelements (Al, Fe, Mn, K, Mg, and Ca) upon Sr contamination and sorbent addition was monitored.Materials and methods
The model soil was contaminated by inactive Sr, in the form of Sr(NO3)2 solution. As a soil additive, sorbent obtained by annealing bovine bones at 400 °C (B400) was applied. Both the uncontaminated and Sr-contaminated soils were mixed with 1, 3, 5, and 10 % of sorbent, suspended in distilled water (initial pH?5; solid/solution ratio, 1:2), and equilibrated for 15 days on a rotary shaker. Solid residues were subjected to modified Tessier five-step sequential extraction analysis, and the amounts of chosen metals in each fraction were determined by inductively coupled plasma–optical emission spectroscopy.Results and discussion
In the original soil, Sr was mainly found in exchangeable (61 %) and carbonate phase (16 %), whereas after contamination, the content of Sr in exchangeable phase raised to 94 %. With the addition of B400, the decrease in Sr amounts in exchangeable fraction was detected, whereas increase occurred mainly in operationally defined carbonate phase and in the residual. High level of Sr contamination caused the increase in Zn, Ni, Co, Cu, Cd, and Mn and decrease in Ca content in exchangeable phase. Sorbent addition resulted in a migration of these cations to less soluble fractions. This effect was observed even for major soil elements such as Fe, Al, and Mn, regardless of the excessive amounts of Sr in the soil.Conclusions
Mixing the soil with B400 resulted in reduced Sr mobility and bioavailability. B400 acted as a stabilizing agent for heavy metals, as well. Apatite distinguished selectivity towards heavy metals may interfere with the Sr immobilization and disrupt original cation distribution. Further studies should include more realistic (lower) Sr concentrations in the soil, different soil types, pH, and longer incubation times. 相似文献117.

The stem and roots of Hornschuchia obliqua provided two new alkaloids, 4,5-didehydroguadiscine and demethoxyguadiscine. Four known alkaloids, roemerine, guadiscine, liriodenine and cleistopholine were also isolated. The structures of the novel compounds were elucidated by spectroscopic analysis, including 2D NMR and MS. 相似文献
