Abstract The aim this study was to evaluate the effect of salicylic acid (SA) in Schinus terebinthifolia seedlings subjected irrigation intervals. experiment performed by 78 days, under four intervals: 0, 4, 8, and 12 combination with concentrations SA: 50, 100, 200 mg L-1. individually maintaining water retention capacity 100%, each maximum height across intervals 24.74 cm at 7-days intervals,...

The use of Acetyl Salicylic Acid (ASA) in the secondary prevention of cardio vascular diseases is well known. Orally administered ASA is rapidly metabolized to its principal metabolite Salicylic Acid (SA) in the gastrointestinal fluids, during absorption in the intestine and liver. ASA, and not its hydrolysis product SA, which exhibits antithrombotic activity. Transdermal delivery of acetylsali...

salicylic acid (sa) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. the physiological mechanism of exogenous sa to affect the senescence of cut lisianthus flowers during vase life was investigated. fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mm sa and then held at 25◦c up to 12 days. ...

Cinnamate-4-hydroxylase (C4H) converts trans-cinnamic acid (CA) to p-coumaric acid (COA) in the phenylpropanoid/lignin biosynthesis pathway. Earlier we reported increased expression of AaCYP71AV1 (an important gene of artemisinin biosynthesis pathway) caused by CA treatment in Artemisia annua. Hence, AaC4H gene was identified, cloned, characterized and silenced in A. annua with the assumption t...

Tobacco mosaic virus (TMV) and Cucumber mosaic virus expressing green fluorescent protein (GFP) were used to probe the effects of salicylic acid (SA) on the cell biology of viral infection. Treatment of tobacco with SA restricted TMV.GFP to single-epidermal cell infection sites for at least 6 d post inoculation but did not affect infection sites of Cucumber mosaic virus expressing GFP. Microinj...

SUMMARY The phytotoxin coronatine is a jasmonate mimic produced by Pseudomonas syringae pv. tomato (Pst). Coronatine acts as a virulence factor in Arabidopsis and mutants insensitive to coronatine are resistant to Pst and have higher levels of salicylic acid (SA). In this work we used the SA-deficient lines NahG and sid2-2 to determine if coronatine acts directly as a virulence factor or indire...

Low temperature induces several genes to acquire plant cold tolerance. Here, we demonstrate that accumulation of salicylic acid (SA) is involved in the regulation of the DREB1A/CBF3 regulon and plant tolerance to cold stresses. The SA-accumulating mutant siz1 exhibits sensitivity to chilling and freezing conditions and decreased expression of DREB1A/CBF3 and its regulon genes. Reduction of SA l...

Salicylic acid (SA) is an important signal involved in the activation of plant defence responses against abiotic and biotic stress. SA may derive from the phenylpropanoid pathway or via isochorismate synthase as demonstrated in Nicotiana benthamiana, tomato and Arabidopsis thaliana. The phenylpropanoid pathway as well as isochorismate synthase are localized in the chloroplasts but it remains un...
