It remains an open question whether violets use universal mechanisms, such as the production of metallothioneins, phytochelatins, and organic acids and/or rely on specific mechanisms like antimicrobial cyclic peptides (cyclotides) for heavy metal tolerance. To contribute to understanding role cyclotides, we used seed-derived plants from metallicolous (M) non-metallicolous (NM) populations Viola tricolor, a pseudometallophyte tolerant Zn Pb. Eight- ten-week-old were treated with 1000 μM or Pb...
Common buckwheat is a valuable crop, mainly due to the beneficial chemical composition of its seeds. However, cultivation limited because unstable seed yield. The most important reasons for low yield include embryo and flower abortion. aim this work verify whether high temperature affects embryological development in plant species. experiment was conducted on plants Polish cultivar 'Panda' strain PA15, which percentage degenerating sacs previously determined amounted 32% 10%, respectively....
Common buckwheat (Fagopyrum esculentum Moench) is a valuable crop plant with cereal-like seed chemical composition; however, it susceptible to thermal stress. The aim of the study was determine whether heat-shock proteins HSP-90 and HSP-70 can protect common against stress during development microspores embryo sacs. performed on two accessions buckwheat, Panda PA15, which differed in their tolerance Accumulation these determined buds, open wilted flowers, donor leaves plants grown at 20°C...
The Violaceae family is rich in metal-tolerant species and producing cyclic peptides (cyclotides) that are linked to the resistance biotic factors. Plants inhabit areas polluted with heavy metals have developed various mechanisms of tolerance. To test role cyclotides protection against abiotic factors, including metals, cell suspension cultures Viola species/genotypes (V. lutea ssp. westfalica, V. tricolor, arvensis, uliginosa), representing different levels tolerance (from most tolerant-MET...
Viola banksii, the type species of section Erpetion, is endemic in eastern mainland Australia. In this paper we characterise morphological and anatomical features assess genome size genetic diversity combination with breeding system. V. banksii develops exclusively chasmogamous flowers. Ovules are anatropous, crassinucellate bitegmic, female gametophyte Polygonum type, embryo Asterad surrounded by nuclear endosperm. Pollen non-heteromorphic, 3-aperturate, highly viable. grows shade on moist,...
Despite abundant flowering throughout the season, common buckwheat develops a very low number of kernels probably due to competition for assimilates. We hypothesized that plants with shorter period may give higher seed yield. To verify hypothesis, we studied nutrient stress in vitro and planta analyzed different embryological yield parameters, including hormone profile flowers. In cultivated flowers on media strongly reduced content demonstrated drastic increase degenerated embryo sacs....

In the current studies, heavy metal tolerance level, accumulation efficiency and sexual reproduction were determined in Viola × wittrockiana, a non-metallophytic ornamental cultivar comparison to V. tricolor, metallophyte, after zinc (Zn) or lead (Pb) treatment (0, 10, 100 1 000 ppm) pot experiments. The seed germination frequency that was not reduced control, effective Zn absorption from soil exclusion strategy for Pb, as well regular of wittrockiana treated with metals all indicate this...
<p>The study was designed to determine the proper conditions for suspension culture of <em>Viola tricolor</em> cells in toxicity studies Pb at different concentrations (0, 200, 500, 1000, 2000 µM) and exposure times (24, 48, 72 h). By forming insoluble salts with ions from medium, lead (II) nitrate added medium decreased initial 5.7–5.8 pH depending on salt concentration light intensity.</p><p>In alamarBlue assays, we found no dose- or time-dependent effect cell...
Arabidopsis arenosa is a good candidate for phytoremediation due to its high tolerance Zn and Cd as well accumulation ability. However, small size low biomass are the largest obstacles applying it on broad scale. The aim was obtain polyploid specimens, which tend have higher increase translocation capacity of heavy metals in this metal-tolerant plant. Doubled polyploids (octaploids) were obtained via indirect organogenesis ½ MS medium supplemented with 1 mg L−1 TDZ, followed by rooting same...
Zanieczyszczenia gleby metalami ciężkimi mają toksyczne działanie na rośliny, zwierzęta oraz człowieka. Metalofity, rośliny odporne metale ciężkie, kolonizujące tereny metalonośne, są wykorzystywane do fitoremediacji, czyli oczyszczania gleb z metali ciężkich. Wykorzystanie roślinnych kultur komórkowych badań nad toksycznością i tolerancją komórek ich jest stosunkowo nową techniką. W pracy zostały przedstawione możliwości wykorzystania zawiesinowych w badaniach wpływem ciężkich metabolizm...
