Brassica napus L. is a main oilseed crop cultivated around the world. Plant growth-promoting rhizobacteria (PGPR) are generally applied to a wide range of agricultural crops for the growth enhancement. In this study, an I-plate technique was used to investigate the plant growth-promoting activity of Pseudomonas putida (strain ATCC12633) on B. napus plants. The volatile organic compounds (VOCs) produced by P. putida were determined by gas chromatography-mass spectrometric (GC-MS) analysis. Furthermore, P. putida were evaluated for its efficacy to induce resistance-related enzymes like peroxidase (POD), phenylalanine ammonia-lyase (PAL), catalase (CAT), and other biochemical compounds such as proline (Pro) and hydrogen peroxide (H2O2) in B. napus plants. According to the results, P. putida significantly increased the growth of B. napus compared to control. The major VOCs released by P. putida were 2-Butynedioic acid, dimethyl ester, Dimethyl ester of 4,7-dimethylnaphthalene-1,2-dicarboxylic acid, N-[3-Methylaminopropyl]aziridine, Cyclododecane, and Hexadecanoic acid. B. napus seeds treatment with P. putida caused enhanced activities of POD, PAL, CAT, Pro, and H2O2 compared to control. So, the results of the present study showed that inoculation of B. napus with P. putida could serve as a useful tool for promoting the plant growth and inducing systemic resistance.

欧洲油菜和恶臭假单胞菌(菌株 ATCC12633)之间的相互作用以及细菌产生的挥发性有机化合物的表征

欧洲油菜是世界各地种植的主要油料作物。植物生长促进根际细菌 (PGPR) 通常应用于多种农作物以促进生长。在本研究中,I-plate 技术用于研究恶臭假单胞菌(菌株 ATCC12633)对欧洲油菜植物的植物生长促进活性。恶臭假单胞菌产生的挥发性有机化合物 (VOC) 由气相色谱-质谱 (GC-MS) 分析确定。此外,还评估了恶臭假单胞菌诱导耐药相关酶如过氧化物酶 (POD)、苯丙氨酸解氨酶 (PAL)、过氧化氢酶 (CAT) 和其他生化化合物如脯氨酸 (Pro) 和过氧化氢 (H2O2) 的功效。 ) 在欧洲油菜植物中。结果表明,恶臭假单胞菌显着促进了 B. 油菜与对照相比。恶臭假单胞菌释放的主要挥发性有机化合物是 2-丁炔二酸、二甲酯、4,7-二甲基萘-1,2-二甲酸的二甲酯、N-[3-甲基氨基丙基]氮丙啶、环十二烷和十六烷酸。与对照相比,用恶臭假单胞菌处理欧洲油菜种子导致 POD、PAL、CAT、Pro 和 H2O2 的活性增强。因此,本研究的结果表明,用恶臭假单胞菌接种欧洲油菜可以作为促进植物生长和诱导系统抗性的有用工具。和 H2O2 与对照相比。因此,本研究的结果表明,用恶臭假单胞菌接种欧洲油菜可以作为促进植物生长和诱导系统抗性的有用工具。和 H2O2 与对照相比。因此,本研究的结果表明,用恶臭假单胞菌接种欧洲油菜可以作为促进植物生长和诱导系统抗性的有用工具。
