Morphogenic responses, ROS generation and changes in enzymes activity induced by the short-term exposure of barley roots to Cd were very similar to those of triiodobenzoic acid (TIBA) treatment. Both Cd and TIBA markedly increased the amount of IAA in root apex. In addition, the treatment of roots with TIBA before Cd treatment had an additive effect on morphogenic responses, changes in enzymes activity...
Agriculture is an important livelihood activity in the Himalayan regions. Our previous studies revealed the presence of diverse diazotrophic assemblage in indigenous red kidney bean (RKB) rhizospheric soil from two different locations of Western Indian Himalaya, namely S1 (Chhiplakot, 30.70° N/80.30° E) and S2 (Munsyari, 30.60° N/80.20° E), selected on the basis of real-time PCR analysis. In this...
A potent phytase-producing bacterium Bacillus lehensis MLB2 was isolated from bean-grown soil. The optimum conditions recorded after optimization were 24 h incubation time, pH 5.5, 37°C, 2% inoculum level, 0.5% rice bran and 0.5% potassium nitrate. An overall 3.144-fold enhancement in phytase production was achieved after optimization. The use of an inexpensive substrate rice bran and short incubation...
Fusarium wilt of chickpea, caused by Fusarium oxysporum f. sp. ciceris (Foc) is one of the most important fungal diseases worldwide. The detection of the pathogen at reasonable time period is of great importance, which requires rapid and sensitive detection methods. The intraspecific divergence sequences found in the intergenic spacer region (IGS) were selected and utilized with the aim to develop...
Rocky shores are among the most-intensively studied ecosystems, however, tidal pools remain relatively understudied. This study aims to investigate the habitat use and dynamics of the shrimp species that occur in tidal pools of a North-eastern Atlantic coast, the Portuguese coast, in particular species composition, abundance, seasonality and size structure. Shrimps were sampled monthly from six tidal...
The bacterial diversity of Pectinatella magnifica colonies sampled from pounds in South Bohemia during the summer of 2012 was investigated. The bacterial counts determined after cultivation on modified yeast extract-tryptone agar (Oxoid) supplemented with glucose (1 g L−1) varied from 4.22 to 6.61 and from 1.30 to 6.85 log CFU/g for aerobes and anaerobes, respectively. Higher counts were found in...
A new chigger mite Grandjeana kanuchi sp. n. collected from the bat Cardioderma cor (Peters, 1872) (Megadermatidae) in Ethiopia (North-East Africa) is described. Additional comments on hosts and distribution records of the chiggers of genus Grandjeana are provided. With the newly described species the genus Grandjeana includes 10 species, three of them are occurring in Africa and seven in South Asia...
Cousinia Cass. is one of the largest genuses in the Asteraceae. It contains 600 to 700 species in Southwest and Central Asia, in Iran with 270 species is the largest genus after Astragalus, Cousinia probably is unique in the degree of diversification of all its parts and definitely unique in the restricted distribution area of a high number of species. Some of Cousinia species have medicinal value...
The chromosomal banding analysis of the karyotypes of Turkish populations of Eptesicus serotinus, Nyctalus lasiopterus and Barbastellus barbastellus was performed with the use of C-banding and Ag-NOR staining. The results obtained in E. serotinus and N. lasiopterus were congruent with previous data reported from other regions. The karyotype of E. serotinus (2n = 50, NF = 52) contained a moderate amount...
Amylolytic enzymes are a starch hydrolyzing important group of industrial enzymes with a multi-dimensional utility. In the present study, endophytic bacteria were isolated from Potentilla fulgens Wall. and screened for their amylolytic activity. Out of total 13 endophytic bacteria isolated, 3 of them showed positive results for amylolytic activity, i.e. production of halo zone against blue background...
Analysis of annual and plot variations of egg batches number of Thaumetopoea pityocampa at the southern limit of its distribution area and in Pinus halepensis afforestations situated in the Algerian sub-Saharan region showed that its fecundity depends on the density of its population, plots, years and interaction of plots-years. It appears that the high average abundance of egg batches/trees during...
Calcareous fens are habitats that are well-adapted to extreme ecological conditions (water with a very high calcium content). The vegetation response following the application of restoration measures (mowing, removal of shrubs) in a calcareous fen (site Sliačske travertíny, western Carpathians) was observed over six years in six permanent plots. Three plots were established in an area strongly invaded...
Changes in richness, diversity, evenness and abundance of phytoplankton in relation to environmental variables and tributary entrances were studied along 30 km of the Paraná River downstream Itaipu Reservoir. A high number of taxa was found, 315. The Paraná River differed from the tributaries Iguaçcu River and Monday River. The phytoplankton and limnological characteristics of the Paraná River changed...
Rubus hyrcanus is considered as an important wild blackberry species scattered around the Caspian Sea. In this research, ISSR and morphological markers were used to assess genetic diversity in several populations of R. hyrcanus from various geographical regions of Caspian Sea in Iran. Twenty-five populations of R. hyrcanus from three regions (NorthWestern (NW), North-Eastern (NE) and Central (C))...
The Holarctic butterflies of the genus Erebia (Lepidoptera) in the Western Carpathians is represented by around 10 mainly mountain species. In this study, phylogenetic relationships among Erebia euryale, E. medusa, E. manto, E. epiphron, E. pharte, E. gorge, E. aethiops, E. pronoe, E. pandrose, and E. ligea from different Western Carpathians localities were compared with other Erebia species on the...
