Microbial communities on aerial plant leaves may contribute to the degradation of organic air pollutants such as phenol. Epiphytic bacteria capable of phenol degradation were isolated from the leaves of green ash trees grown at a site rich ...
Influence of host plant genotype, presence of a pathogen, and coinoculation with Pseudomonas fluorescens strains on the rhizosphere expression of hydrogen cyanide- and 2,4-diacetylphloroglucinol biosynthetic genes in P. fluorescens biocontrol strain CHA0 [0.03%]
寄主植物基因型、病原体的存在和Pseudomonas fluorescens菌株重渗对生物防治菌CHA0合成氢氰酸和2,4-二乙酰基土曲霉素基因根际表达的影响
