Differences in the amino acid sequence between the bispecific NAD(P)H-nitrate reductase of birch (Betula pendula Roth) and the monospecific NADH-nitrate reductases of a variety of other higher plants have been found at the dinucleotide-binding site in the FAD domain. To pinpoint amino acid residues

Expression analysis of the BpARF genes in Betula platyphylla under drought stress.

Auxin response factors (ARFs) play an important role in modulating plant growth and development processes by regulating the expression of auxin-responsive genes. However, the modes of action of ARFs in birch (Betula platyphylla) remain largely unknown. In this study, fifteen ARF genes were

A low molecular weight allergen of white birch (Betula verrucosa) is highly homologous to human profilin.

Cloning of allergens has contributed substantially to the understanding of mechanisms in allergic diseases by providing information about the sequence and hence biological functions of allergens. The major birch pollen allergen, Bet v I [Breiteneder H, et al: EMBO J 1989;8:1935-1938] and the

An Ethylene-responsive Factor BpERF11 Negatively Modulates Salt and Osmotic Tolerance in Betula platyphylla.

Ethylene responsive factors (ERFs) play important roles in the abiotic stress; however, only a few ERF genes from woody plants have been functionally characterized. In the present study, an ERF gene from Betula platyphylla (birch), BpERF11, was functionally characterized in response to abiotic

Crosstalk among nitric oxide, calcium and reactive oxygen species during triterpenoid biosynthesis in Betula platyphylla

Numai utilizatorii înregistrați pot traduce articole

We analysed NO, reactive oxygen species (ROS) and Ca2+ crosstalk during triterpenoid biosynthesis in white birch (Betula platyphylla Suk.) cells. Cells were pretreated with diphenyleneiodonium, sodium diethyldithiocarbamate (DDTC) or catalase (CAT), or a Ca2+ channel blocker or chelator before

Betula platyphylla BpHOX2 transcription factor binds to different cis-acting elements and confers osmotic tolerance

The homeodomain-leucine zipper (HD-Zip) proteins play crucial roles in plant developmental and environmental responses. However, how they mediate gene expression to facilitate abiotic stress tolerance remains unknown. In the present study, we characterized BpHOX2 (encoding a HD-Zip I family protein)

Expression of the MYB transcription factor gene BplMYB46 affects abiotic stress tolerance and secondary cell wall deposition in Betula platyphylla.

Plant MYB transcription factors control diverse biological processes, such as differentiation, development and abiotic stress responses. In this study, we characterized BplMYB46, an MYB gene from Betula platyphylla (birch) that is involved in both abiotic stress tolerance and secondary wall

Rough wave-like heaped overburden promotes establishment of woody vegetation while leveling promotes grasses during unassisted post mining site development.

Geodiversity plays an important role in species establishment during spontaneous succession. At post-mining sites in the Czech Republic in 2003, we established plots in which the surface of the heaped overburden was either kept wave-like or leveled. Based on surveys conducted from 2006 to 2015,

Characterization of profilin polymorphism in pollen with a focus on multifunctionality.

Numai utilizatorii înregistrați pot traduce articole

Profilin, a multigene family involved in actin dynamics, is a multiple partners-interacting protein, as regard of the presence of at least of three binding domains encompassing actin, phosphoinositide lipids, and poly-L-proline interacting patches. In addition, pollen profilins are important

Air pollution tolerance index and heavy metal bioaccumulation in selected plant species from urban biotopes.

Numai utilizatorii înregistrați pot traduce articole

This research was carried out on plants Taraxacum officinale, Plantago lanceolata, Betula pendula and Robinia pseudoacacia growing in urban biotopes with different levels of heavy metal contamination in the city of Dąbrowa Górnicza (southern Poland). Based on the pollution index, the highest heavy

Identification of profilin as a novel pollen allergen; IgE autoreactivity in sensitized individuals.

Numai utilizatorii înregistrați pot traduce articole

A complementary DNA encoding a pollen allergen from white birch (Betula verrucosa) that was isolated from a pollen complementary DNA library with serum immunoglobulin E from a birch pollen-allergic individual revealed significant sequence homology to profilins. The recombinant protein showed high
