* Intergeneric hybrids between Lolium multiflorum and Festuca pratensis (Lm/Fp) and their derivatives exhibit a unique combination of genetic and cytogenetic characteristics: chromosomes undergo a high frequency of homoeologous recombination at meiosis; the chromosomes of the two species can easily be discriminated by genomic in situ hybridization (GISH); recombination occurs along the entire l...

Chloroplast genome sequences are of broad significance in plant biology, due to frequent use in molecular phylogenetics, comparative genomics, population genetics, and genetic modification studies. The present study used a second-generation sequencing approach to determine and assemble the plastid genomes (plastomes) of four representatives from the agriculturally important Lolium-Festuca speci...

Phenetic data on over 60 heterotrophic, Gram-negative, yellow chromogenic bacteria from plant material were collected and analysed using numerical taxonomic methods. Marker strains representing 42 taxa were included in the analyses. At similarity levels of 80% or above, eight distinct clusters were obtained, the first four of which included yellow chromogens. Custer I contained isolates from gr...

Leaf slices of the sethoxydim sensitive grasses Poa pratensis and Festuca ovina and the sethoxy­ dim resistant grasses Poa annua and Festuca rubra take up the herbicide at similar rates. Uptake is almost linear with concentration up to 2 m M , independent of light and little affected by tempera­ ture between 0 and 25 °C. Uptake is highly pH sensitive. At pH 7.0 rates o f uptake are only about 2...

This article provides information on the ecology of lawn communities in cities Urals Republic Bashkortostan (Ufa, Sterlitamak, Salavat, Ishimbay, Meleuz, Birsk, Neftekamsk, Yanaul). On basis 195 relevés, ecological regimes and their species were determined using scales Landolt. DCA ordination relevés confirmed floristic differentiation into 4 associations, 2 subassociations, 5 facies assigned t...
