从油菜根际和根际土壤中分离出13株能在氮素缺乏的培养条件下生长的革兰氏阴性细菌，并通过16 SrDNA序列分析鉴定。这些细菌中的8个诱导了根干重的显着增加，范围从11%至52%。基于16 S rDNA序列的系统发育定位表明，至少有4个属，假单胞菌属（Pseudomonas）、Vario-vorax、土壤杆菌属（Agrobacterium）和叶杆菌属（Phyllobacterium）。
Thirteen of the most abundant Gram-negative bacteria which are able to grow in N-depleted culture conditions were isolated from the rhizoplane and endorhizosphere of canola (Brassica napus) and identified by 16S rDNA sequence analysis. Eight of these bacteria induced a significant increase in root dry weight ranging from 11 to 52%. Phylogenetic positioning based on 16S rDNA sequences indicated that at least four genera are represented, Pseudomonas, Vario-vorax, Agrobacterium and Phyllobacterium, The most important direct plant growth-promoting-rhizobacteria effect was found with both isolates belonging to the Phyllobacterium.
