Salinization of agricultural areas due to intensive practices and irrigation is an important feature limiting crop yield and productivity. Inhibition of plant growth and even plant death by salinity is due to a reduction in water availability, sodium ion accumulation and mineral imbalances. In this context, ROS will be produced in both SALT STRESS AND GLUTATHIONE-DEPENDENT ENZYME ACTIVITIES IN ...

Chromium was not required for normal growth of romaine lettuce (Lactuca sativa L. subsp. longifolia), tomato (Lycopersicon esculentum Mill.), wheat (Triticum aestivum L.), or bean (Phaseolus vulgaris L.) in solution culture containing 3.8 x 10(-4) muM Cr. Plants grown on this purified nutrient solution contained an average of 22 ng Cr/g dry weight. Duckweed (Lemna sp.) grew and reproduced norma...

in order to select the suitable lines of red bean for chahharmahal & bakhtiari province, this experiment was conducted in lordegan & boldaji regions at 2001-2005. at the first year, single plants of local red bean (from lordegan, ardal, boldaji, dastgerd emamzadeh and gandoman regions) were selected at research farm for phenotypic characters, yield and yield components. at the second year, sele...

The localization of ethylene-induced endochitinase was studied in bean (Phaseolus vulgaris L. cv Saxa) leaves. The specific activity of chitinase in mesophyll protoplasts isolated from the leaves was as high as in tissue homogenates, indicating that most of the enzyme was located intracellularly. Vacuoles isolated and purified from the protoplasts were found to contain most of the intracellular...

A pulse of blue light induced both a transient increase in activity of apoplastic K+ and membrane depolarization in laminar pulvinus of Phaseolus vulgaris L. This shows that blue-light-induced net efflux of K+ from motor cells is closely related to membrane depolarization.
