Acetylsalicylic acid enhance tolerance of Phaseolus vulgaris L. to chilling stress, improving photosynthesis, antioxidants and expression of cold stress responsive genes

Evaluation of Tolerance Rate of Some Genotypes of Beans (Phaseolus Vulgaris L.) To Salinity Stress

     Evaluation of the physiological and biochemical traits can help to identify strategies for selection of resistant cultivars and increased crop yield production under diverse environmental conditions such as SALT stress conditions. To this end, an experiment was conducted in a greenhouse based on a completely randomized design (CRD) with three replications. The experimental factors were six...

Analysis of Stress-Responsive Gene Expression in Cultivated and Weedy Rice Differing in Cold Stress Tolerance

Rice (Oryza sativa L.) cultivars show impairment of growth in response to environmental stresses such as cold at the early seedling stage. Locally adapted weedy rice is able to survive under adverse environmental conditions, and can emerge in fields from greater soil depth. Cold-tolerant weedy rice can be a good genetic source for developing cold-tolerant, weed-competitive rice cultivars. An in...

Update on Adaptation to Physical Stress Role of Cold-Responsive Genes in Plant Freezing Tolerance

Plants vary greatly in their ability to survive freezing temperatures. At one extreme are plants from tropical regions that have virtually no capacity to survive even the slightest freeze. In contrast, herbaceous plants from temperate regions generally survive freezing temperatures ranging from 25°C to 230°C, depending on the species, whereas perennials in the boreal forests routinely survive w...

Mg-Protoporphyrin IX Signals Enhance Plant’s Tolerance to Cold Stress

The relationship between Mg-protoporphyrin IX (Mg-Proto IX) signals and plant's tolerance to cold stress is investigated. Arabidopsis seedlings grown for 3 weeks were pretreated with 2 mM glutamate (Glu) and 2 mM MgCl2 for 48 h at room temperature to induce Mg-Proto IX accumulation. Then cold stress was performed at 4°C for additional 72 h. Glu + MgCl2 pre-treatments alleviated the subsequent c...
