Salicylic Acid Protects Photosynthesis against Cadmium Toxicity in Pea Plants
In the present study we have investigated the possible mediatory role of salicylic acid (SA) in protecting photosynthesis against cadmium (Cd) toxicity. The exposure of pea plants to increasing Cd concentrations (0.5, 1.0, 2.0 and 5.0 µM) during early stages of their establishment caused a gradual decrease in shoot and root fresh weight accumulation, the rate of CO 2 fixation and the activity o...
متن کاملSalicylic acid alleviates the cadmium toxicity in barley seedlings.
Salicylic acid (SA) plays a key role in plant disease resistance and hypersensitive cell death but is also implicated in hardening responses to abiotic stressors. Cadmium (Cd) exposure increased the free SA contents of barley (Hordeum vulgare) roots by a factor of about 2. Cultivation of dry barley caryopses presoaked in SA-containing solution for only 6 h or single transient addition of SA at ...
متن کاملSalicylic acid beyond defence: its role in plant growth and development.
In recent years salicylic acid (SA) has been the focus of intensive research due to its function as an endogenous signal mediating local and systemic plant defence responses against pathogens. It has also been found that SA plays a role during the plant response to abiotic stresses such as drought, chilling, heavy metal toxicity, heat, and osmotic stress. In this sense, SA appears to be, just l...
متن کاملSalicylic Acid and Sodium Salicylate Alleviate Cadmium Toxicity to Different Extents in Maize (Zea mays L.)
The role of salicylic acid in Cd tolerance has attracted more attention recently but no information is available on the efficiency of different forms of salicylic acid. The aim was thus to investigate whether both the acid and salt forms of salicylic acid provide protection against Cd stress and to compare their mode of action. Young maize plants were grown under controlled environmental condit...
متن کاملSystemic toxicity from topically applied salicylic acid.
Topically applied salicylic acid has enjoyed long and extensive usage as an agent to enhance desquamation in various hyperkeratotic skin diseases. In some of these disorders much of the skin surface may be affected, resulting in the potential for significant percutaneous absorption of the drug. We describe a patient who gradually developed evidence of severe salicylate toxicity while being trea...
