cyphomandra betacea (cav.) is a native species from south america that is cultivated because its fruits have a high content of vitamins. in colombia, it is common to find periods of drought between the rainy seasons or during enso events such as el niño. an adequate nutritional status of k+ in plants helps to increase the chance of tolerating the negative effects of drought stress. regarding th...

Phytoremediation counts as a major method for future which essentially needs resistance to contaminating agents. We pretreated the plants (Salix babylonica, as a model plant in phytoremediation of polluted waters) by sodium cyanide (0, 3 and 5 mg CN- L-1) to induce resistance with regard to acclimation and then examined their resistance to higher concentrations of cyanide. Accordingly, some of ...

Nitric oxide (NO) is an important signaling molecule involved in many physiological processes in plants. We evaluated the role of NO in cold acclimation and freezing tolerance using Arabidopsis (Arabidopsis thaliana) wild type and mutants nia1nia2 (for nitrate reductase [NR]-defective double mutant) and Atnoa1/rif1 (for nitric oxide associated1/resistant to inhibition by fosmidomycin1) that exh...

Plants growing in different environments develop with different photosynthetic capacities--developmental acclimation of photosynthesis. It is also possible for fully developed leaves to change their photosynthetic capacity--dynamic acclimation. The importance of acclimation has not previously been demonstrated. Here, we show that developmental and dynamic acclimation are distinct processes. Fur...

Red osier dogwood (Cornus stolonifera Michx.) was artificially acclimated by exposing plants to 8-hour short days (SD) and low (15/5 C) temperatures for 54 to 63 days. Several factors including transpiration rate, stomatal resistance, and root conductivity were correlated so that the rate of water loss in acclimating plants was higher during the first 30 to 40 days of the acclimation sequence. ...

Efficient acclimation to different growth light intensities is essential for plant fitness. So far, most studies on light acclimation have been conducted with plants grown under different constant light regimes, but more recent work indicated that acclimation to fluctuating light or field conditions may result in different physiological properties of plants. Thale cress (Arabidopsis thaliana) w...
