Salicin, Salicylic Acid and Its Salts
comparative value of this drug with that of other medicinal agents which have already received the sanction of experience, amongst the foremost of which may be mentioned the wet-pack quinine, atropine, aconite, &c., administered subcutaneously. I have tried the last three side by side with salicin, and by thermometric observations during the past two years I have failed to find any superiority ...
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 کاملNitric oxide and salicylic acid signaling in plant defense.
Salicylic acid (SA) plays a critical signaling role in the activation of plant defense responses after pathogen attack. We have identified several potential components of the SA signaling pathway, including (i) the H(2)O(2)-scavenging enzymes catalase and ascorbate peroxidase, (ii) a high affinity SA-binding protein (SABP2), (iii) a SA-inducible protein kinase (SIPK), (iv) NPR1, an ankyrin repe...
متن کاملA central role of salicylic Acid in plant disease resistance.
Transgenic tobacco and Arabidopsis thaliana expressing the bacterial enzyme salicylate hydroxylase cannot accumulate salicylic acid (SA). This defect not only makes the plants unable to induce systemic acquired resistance, but also leads to increased susceptibility to viral, fungal, and bacterial pathogens. The enhanced susceptibility extends even to host-pathogen combinations that would normal...
متن کاملRole of salicylic acid in plant abiotic stress.
Salicylic acid (SA) plays many roles in plant physiology. Besides pathogenesis-related resistance, SA is involved in the response to abiotic stress. However, the effects of SA on plant resistance to abiotic stress were found contradictionary, and the actual role of SA in abiotic stress remains unresolved. Generally, deficiency of SA or a very high level of SA increase the plant susceptibility t...
