- Abstract:
- ... At a molecular level, the length of the vernalization period of common wheat (Triticum aestivum L.) is determined mainly by three loci: VRN-1, VRN-2 and VRN-3. In hexaploid wheat, the Vrn-A1, Vrn-B1 and Vrn-D1 genes are dominant for spring growth habit and epistatic to the alleles for winter growth habit. We used DNA markers to determine the VRN-1 genotypes of 43 common wheat cultivars from the Po ...

- Abstract:
- ... We measured cadmium and lead concentrations in two littoral plants (Phragmites australis Cav. Trin ex. Steudel and Typha angustifolia L.) collected in June and September 2007 from five selected lakes in the Poznan city area, and also in sediment and water samples from the same places. We determined the metal concentrations in rhizomes and leaves, and in sediment and water from the littoral and nea ...

- Abstract:
- ... The influence of initial medium pH on long-term axillary shoot proliferation was tested in Anderson's media supplemented with 0.5 mg.l⁻¹ zeatin with initial pH adjusted to 4.0, 4.5, 5.0, 5.5 and 6.0 before autoclaving, with the aim of increasing shoot proliferation in Vaccinium vitis-idaea L. cv. Koralle and Red Pearl. Shoot proliferation using in-vitro-derived single-node segments was markedly in ...

- Abstract:
- ... Ultraviolet-B (UV-B) radiation negatively affects plant cells, causing reactive oxygen species (ROS) to be generated. To study the effects of increased UV-B exposure on antioxidant processes, we exposed germination-stage cucumber seedlings to increased ultraviolet radiation and analyzed hydrogen peroxide content and the activity of superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (G ...

- Abstract:
- ... We estimated similarity and differences at the level of isozymes among populations of Malva alcea from various habitats and parts of Central Europe. Our analyses revealed the activity of 8 enzyme systems: 6 polymorphic (PGI, IDH, PX, DIA, PGM, SHD KB) and 2 monomorphic (GOT, ME). The mean number of alleles per locus is 2.12. Nei's genetic distances among populations are small, not exceeding 0.3. M ...

An efficient plant regeneration protocol has been developed from nodal explants of Ocimum kilimandscharicum Guerke, a medicinally important herbaceous plant species belonging to the family Lamiaceae. Axillary shoot bud proliferation was initiated from nodal explants cultured on MS medium supplemented with various concentrations of 6-benzyladenine (BA) (0.5-3.0 mg/l), kinetin (KN) (0.5-3.0 mg/l) an ...

- Abstract:
- ... MicroRNA miR408 is predicted to target the transcripts for the copper proteins plantacyanin and laccase in Arabidopsis. In this study it was found that miR408 is present in tobacco also. Its accumulation was positively induced by copper deficiency, providing additional evidence for the important role of miR408 in plant responses to nutriment conditions. To examine the functions of miR408 in tobacc ...

We determined the chlorophyll a and b levels (SPAD readings) in uninfested leaves and in leaves after 7 and 17 days of aphid infestation in four Fabaceae species (Pisum sativum L., Vicia faba L., Trifolium pretense L, Medicago sativa L.). Feeding by pea aphids Acyrthosiphon pisum Harris (Hemiptera: Aphididae) caused significant loss of chlorophyll a and b in the infested plants. Uninfested leaves ...

- Abstract:
- ... One of the most important technical challenges in cell biology is visualization of the actin cytoskeleton. The widely used GFP-FABD2 fusion protein is a helpful tool for investigating actin architecture in living plants. Here we report our attempt to visualize F-actin in mature leaves of transgenic Arabidopsis thaliana. With a confocal microscope we observed loss of GFP fluorescence in mature Arab ...

- Abstract:
- ... A successful in vitro propagation system has been developed for the valuable ornamental and medicinal plant rugosa rose (Rosa rugosa Thunb.) by in vitro culture of nodal segments from mature plants. MS media supplemented with BA 2.2 μM, NAA 0.054 μM, GA₃ 2.0 μM and 3% sucrose significantly improved bud break and growth directly from nodal segment explants. High proliferation and average height of ...

We tested autumn frost hardiness in three Norway spruce (Picea abies [L.] Karst.) provenances originating from different altitudes at two trial plots in Slovakia (Vel'ký Lom at 450 m a.s.l., Mútne-Zákamenné at 1,250 m a.s.l.) in a spinoff experiment of the IUFRO 1964/68 Inventory Provenance Experiment with Norway spruce. Two approaches were used to assess hardiness: the electrolyte-leakage method ...

All taxa tested had high content of total polyphenols (from 2.68% in R. orbiculata Bornm. to 8.50% in R. pumila Turra), moderate content of glucofrangulins (from 0.22% in R. pumila to 9.26% in R. fallax Boiss.), nontannic polyphenols (from 0.73% in R. orbicu ...
