Effect of Salicylic Acid on Antioxidant Activity in Milk Thistle Hairy Root Cultures
Background: Elicitors can trigger defense responses and activate specific genes involved in secondary metabolite biosynthesis. Objective: For understanding SA-treatment signaling pathway we determined defense-related compounds and enzymes in S. marianum hairy root cultures. Methods: 28 day old hairy roots were treated by salicylic acid (6 mg/50 ml culture) for different times (24, 48, 72, 96...

متن کاملAlkaloids in plants and root cultures of Atropa belladonna overexpressing putrescine N-methyltransferase.
Putrescine N-methyltransferase (PMT) is the first alkaloid-specific enzyme for nicotine and tropane alkaloid formation. The pmt gene from Nicotiana tabacum was fused to the CaMV 35S promoter and integrated into the Atropa belladonna genome. Transgenic plants and derived root cultures were analysed for gene expression and for levels of alkaloids and their precursors. Scopolamine, hyoscyamine, tr...
متن کاملStructural basis for substrate recognition in the salicylic acid carboxyl methyltransferase family.
Recently, a novel family of methyltransferases was identified in plants. Some members of this newly discovered and recently characterized methyltransferase family catalyze the formation of small-molecule methyl esters using S-adenosyl-L-Met (SAM) as a methyl donor and carboxylic acid-bearing substrates as methyl acceptors. These enzymes include SAMT (SAM:salicylic acid carboxyl methyltransferas...
متن کاملSalicylic Acid in Neuralgia
seven grains of the Carbonate of soda, and give you a brief record of my experiences. During the taking of the first dram, there certainly was an abatement of the pain, and of the burning sensation I almost always have on the side of my face and head, and my pulse fell about five beats per minute, that is, from 72 to 68, and sometimes 65. During the taking of the second dram 1 began to experien...
