Aims This study aimed at revealing the mechanisms of zinc(Zn)-induced root growth inhibition in the Zn hyperaccumulator Noccaea caerulescens and the excluder Microthlaspi perfoliatum to shed light on the intriguing question whether there is any selectivity in the Zn effects on root cell division and elongation. Methods Zinc effects on various para...

Plant growth and productivity are predicted to be affected by rising CO2 concentrations, drought and temperature stress. The C3 crop model in a changing climate is Chenopodium quinoa Willd—a protein-rich pseudohalphyte (Amaranthaceae). Morphophysiological, biochemical and molecular genetic studies were performed on quinoa grown at ambient (400 ppm,...

Abstract: Plant growth and productivity are predicted to be affected by rising CO 2 concentrations, drought and temperature stress. The C 3 crop model in a changing climate is Chenopodium quinoa Willd-a protein-rich pseudohalphyte (Amaranthaceae). Morphophysiological, biochemical and molecular genetic studies were performed on quinoa grown at ambie...

The adaptation of plants to combined stresses requires unique responses capable of overcoming both the negative effects of each individual stress and their combination. Here, we studied the C3-C4 (C2) halophyte Sedobassia sedoides in response to elevated temperature (35 °C) and salinity (300 mM NaCl) as well as their combined effect. The responses...

The effect of drought on the morphophysiological, biochemical, and molecular genetic parameters of plants Sedobassia sedoides (Pall.) Freitag G. Kadereit with an intermediate C3–C4-type of photosynthesis and Bassia prostrata (L.) A.J. Scott with a C4-NADP type of photosynthesis grown at different temperatures (25 and 30°C) was studied. A decrease i...

Chenopodium quinoa is a genetically diverse crop that can adapt to a wide range of environments, including temperatures and salinities. However, only a few studies have assessed the combined effects of two or more environmental factors on C. quinoa. Here, we investigated the effects of salinity (300 mM NaCl), elevated temperature (35 °C), and their...

Cytochrome c3 (uranyl reductase) from Desulfovibrio vulgaris can reduce uranium in bacterial cells and in cell-free systems. This gene was introduced in tobacco under control of the RbcS promoter, and the resulting transgenic plants accumulated uranium when grown on a uranyl ion containing medium. The uptaken uranium was detected by EM in chloropla...

Analysis of root growth parameters was carried out on the seedlings of 53 monocotyledonous and 78 dicotyledonous plant species. Daily increases of the root length, the root diameter, the length of the meristematic and elongation zones, the length and the number of cells in a cell file of the meristematical cortex cells, and the length of the fully...

Analysis of root growth rate’s dependence on the holoploid DNA content was carried out on different plant species. Such dependence was found weakly negative in the primary roots of the dicot seedlings and in the lilioid adventitious root. The dependence was absent in the primary roots of the monocot seedlings. The relative elongation rate for the c...

Background A growing part of the root is one of the most active sinks for sucrose coming from source leaves through the phloem. In the root, sucrose is unloaded from conducting bundles and is distributed among the surrounding cells. To be involved in the metabolism, sucrose should disintegrate into hexoses by means of degrading enzymes. Aims The a...

Copper (Cu) is reported to play a dual role in plants. At low concentrations, it functions as a necessary element participating in carbon assimilation, transport of organic substances, growth, and metabolism of cell walls. Cu needs to sustain the plant based on its role in enzymatic catalysis, in redox reactions, and in the electron transport in th...
