A classification of northern boreal light coniferous forests in the West Siberian plain has been developed using the Braun-Blanquet approach. In the northern part of the West-Siberian plain, boreal coniferous forests occur at the northern limit of their range characterized by a cold continental climate and the prevalence of long-frozen, poorly drained soils in watersheds. All syntaxa were assigned to the class Vaccinio-Piceetea Br.-Bl. in Br-Bl., Siss. & Vlieger 1939. Association Pinetum sibiricae-sylvestris Makhatkov et Ermakov 2010 has been included in the alliance Cladonio stellaris-Pinion sylvestris K.-Lund 1986, order Pinetalia sylvestris Oberd. 1957. Associations Melampyro pratense-Laricetum sibiricae ass. nova hoc loco and Ledo-Pinetum sibiricae ass. nova hoc loco have been included in the alliance Pino sibiricae-Laricion sibiricae Ermakov in Ermakov et Alsynbayev 2004 and the order Ledo palustris-Laricetalia cajanderi Ermakov in Ermakov et Alsynbayev 2004. Results of detrended correspondence analysis ordinations demonstrate a strong floristic integrity of the higher syntaxonomic units and clear syntaxonomic boundary between north boreal forests of the Vaccinio-Piceetea and swamp forests of the Oxycocco-Sphagnetea in spite of transitional floristic features in the majority of communities. © 2011 Copyright Taylor and Francis Group, LLC.

The method of preservation and in vitro propagation of rare species Dianthus mainensis was offered. Seeds were used as starting material for in vitro propagation. Explants were cultured on MS medium supplemented with BAP and NAA. The greatest number of shoots was obtained when supplementing 3 μM BAP (5.5 shoots per an explant). This medium provided direct morphogenesis without appearance of somaclonal variants. Rooting of shoots in vitro observed when using half strength MS medium without growth regulators. Regenerants of Dianthus mainensis were successfully adapted and transferred to the experimental field. Source

Using C-banding and FISH methods, the karyotype of MC1611 induced mutant of bread wheat, which develop additional spikelets at a rachis node (trait “supernumerary spikelets”) was characterized. It was determined that the mutant phenotype is not associated with aneuploidy and major chromosomal rearrange-ments. The results of genetic analysis showed that supernumerary spikelets of the line are caused by a muta-tion of the single Bh-D.1 gene, influenced by the genetic background. The mutation causes a bnormalities of inflorescence morphogenesis associated with the development of ectopic spikelet meristems in place of floral meristems in the basal part of the spikelets, causing the appearance of additional spikes at a rachis node. The mutant phenotype suggests that the Bh-D gene determines the fate of the lateral meristems in ear, which develops as floral meristem and gives rise to floral organs in wild-type inflorescences. In the Bh-D.1 mutant, the floral meristem identity is impaired. The characterized mutant can be used in further studies on molecular genetic basis of development of wheat inflorescence. © Pleiades Publishing, Inc., 2014. Source

This article concerns the spatial distribution patterns of small-leaved forests in the Kuznetsk Depression, where these communities are the forest components of zonal vegetation. Two levels of spatial forest heterogeneity are described. Depending on mesorelief, forest communities are organized into topo-ecological series, which differ in sets of components and area covered by different elements. On a larger scale, depending on climatic features in different parts of the depression, the spatial pattern of communities and topo-ecological series reflect the zonal structures. In general, the spatial forest distribution is considered as follows: the central part of the depression is covered by Artemisio – Betuletum communities in combination with Calamagrostio – Betuletum forests; approaching the eastern border of the depression, they change to Trollio – Populetum and Campanulo – Betuletum combinations; the southern part is occupied by communities of Campanulo – Betuletum, together with Saussureo – Populetum forests; in the north-western part the only forest association is Primulo – Betuletum. Throughout the entire region, in places with bad drainage occur communities of Carici – Betuletum. Based on climatic parameters, forest-steppe and sub-taiga sub-belts can be distinguished. Forest-steppe in its turn can be divided into an original fragment of plain forest-steppe and typical forest-steppe. In the eastern part of the depression, a sub-taiga sub-belt developed but in the western part, it exists outside the depression. © 2015 Taylor & Francis. Source

The records of Ranunculus longicaulis and R. pseudohirculus are cited from Nepal. Both species were earlier identified as R. pulchellus. The key for delimitation as well as taxonomic notes of these three species are provided. Some populations from Central Asia and Himalayas differ in pubescence details and morphometry. Source
