Hernandez-Esquivel, Alma Alejandra;Castro-Mercado, Elda;Garcia-Pineda, Ernesto published 《Comparative Effects of Azospirillum brasilense Sp245 and Pseudomonas aeruginosa PAO1 Lipopolysaccharides on Wheat Seedling Growth and Peroxidase Activity》 in 2021. The article was appeared in 《Journal of Plant Growth Regulation》. They have made some progress in their research.Electric Literature of C7H7NO3 The article mentions the following:
The effects of lipopolysaccharides (LPS) from Azospirillum brasilense Sp245, a plant growth-promoting rhizobacteria, and Pseudomonas aeruginosa PAO1, a pathogenic bacterium, on plant growth and peroxidase (POD) activity were assessed on wheat seedlings. A. brasilense LPS (100μg/mL) increased total length, and total fresh weight in wheat seedlings 4 days after treatment. P. aeruginosa LPS did not show effect on plant growth. A. brasilense LPS increased root hairs length similar to whole cells, while P. aeruginosa LPS increased root hairs d. and slightly root hairs length. Both LPS increased POD activity and hydrogen peroxide (H2O2) content in root; however, the LPS from the pathogenic bacterium generated higher increments. The peroxidase inhibitor salicylhydroxamic acid (SHAM) inhibited plant growth, which was not recovered by the addition of LPS neither A. brasilense nor P. aeruginosa. POD activity stimulated by LPS was calcium-dependent as confirmed by the addition of the calcium channel blocker LaCl3. The results suggest that plant cells sense differentially LPS from beneficial or pathogenic bacteria and that calcium is needed to respond to the presence of both LPS.N,2-Dihydroxybenzamide (cas: 89-73-6) were involved in the experimental procedure.
N,2-Dihydroxybenzamide(cas: 89-73-6) can be used:To prepare phenylboronic acid-based bioconjugates for chromatographic applications;As a ligand to synthesize Fe(III), Cu(II), Ni(II) and Zn(II) complexes.Electric Literature of C7H7NO3
