We previously demonstrated that overexpression of the horseradish (Armoracia rusticana) peroxidase prxC1a gene stimulated the growth rate of tobacco (Nicotiana tabacum) plants. Here, the cauliflower mosaic virus 35S::prxC1a construct was introduced into hybrid aspen (Populus sieboldii x Populus grandidentata). The growth rate of these transformed hybrid aspen plants was substantially increased ...

Aluminum toxicity is one of the most deleterious factors for plant growth in acidic soils because over 50% of the world’s potentially arable lands are acidic. In recent years, considerable research has been conducted to understand the mechanisms of Al toxicity and tolerance in plants. This paper reviews the effects of different concentration of Al on plant shoot, root physiological parameters s...

Phaseolus vulgaris L. plants were grown in soil supplemented with different Pb and Cd concentrations (2, 4, 6, 8 gKg for Lead and 1.5, 2.0, 2.5, 3.0 gKg for Cadmium). Germination % was remained unaffected at low concentration of both metals as compared to control plants but at higher concentration of Cd i.e. 3g/Kg soil, germination was completely inhibited. Growth was also decreased as concentr...

seedlings of five canola genotypes (hyola308, hyola401, hyola60, optlon50, and rgs003), were grown in hoagland nutrient solution containing s1=0, s2=100, s3=200 and s4=300 mm nacl in controlled environment. such antioxidant activities as catalase (cat), ascobrate peroxidase (apx) and guaiacol peroxidase (gpx), as well as osmolyte concentration (proline), chlorophyll fluorescence and some enzyme...

Deficiency of nitrogen may lead to decrease in yield and yield potential of crop plants. An experiment was done under glasshouse conditions in order to investigate nitrogen levels and salicylic acid interaction on some physiologic traits of borage (Borago officinials L.). In this experiment various levels of nitrogen (including; 27.5, 55, 110, 220 and 330 mg/L from ammonium nitrate) and salicyl...

It is essential to identify and determine the properties of native plants as natural genetic resources. The present study was performed to identify the Mindium (Michauxi) laevigata species using molecular and biochemical procedures such as genomic DNA extraction, sequencing, and antioxidant capacity and protein content determination at both vegetative and generative phases in various parts of t...

The use of soil additives such as selenium can positively influence the antioxidative system plants, making them more tolerant to abiotic stresses. aim this work was evaluate concentration sodium selenite or selenate applied substrate that causes improve in plant growth and enzyme activities sunflower plants. treatments were divided in: control (absence selenium); 0.2 mg L-1 selenate; 0.4 0.8 s...
