Oxidative modification of the cell wall in tomato plants exposed to ozone was written by Wiese, Cosima B.;Pell, Eva J.. And the article was included in Plant Physiology and Biochemistry (Paris, France) in 2003.Application In Synthesis of 3-Hydroxy-5-methoxybenzaldehyde This article mentions the following:
The goal of this research was to define the role of the cell wall in plant exposure to the atm. pollutant ozone (O3). To determine if cell wall components are sensitive to oxidation, cell walls were isolated from tomato leaves (Lycopersicon esculentum cv. Roma) and exposed to O3 or pure oxygen. O3 reduced the a wall-bound benzaldehyde isomer in extractive-free cell wall material thought to have limited enzymic activity. To determine if this oxidative modification also occurred in vivo, tomato plants were exposed to O3 or filtered air, and the buffer soluble and alk. hydrolyzed (wall-bound) phenolic compounds were analyzed. Exposure to O3 decreased the quantity of the wall-bound benzaldehyde isomer within 2-3 h of exposure, with a return to control levels by 5 h of exposure. Quantity of the benzaldehyde isomer in the control samples was unchanged throughout the experiment A glycoside of 5-hydroxyvanillic acid was detected in the buffer soluble fraction of O3-treated samples at 3 h of exposure. Control and O3-treated samples harvested at 5 h of exposure did not contain this compound Results show that cell wall phenolic compounds are sensitive to oxidative modification by plant exposure to O3. A model illustrates the proposed signaling mechanism involving oxidative breakdown products from the cell wall as elicitor mols. In the experiment, the researchers used many compounds, for example, 3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8Application In Synthesis of 3-Hydroxy-5-methoxybenzaldehyde).
3-Hydroxy-5-methoxybenzaldehyde (cas: 57179-35-8) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Application In Synthesis of 3-Hydroxy-5-methoxybenzaldehyde
