Phosphorus (P) is an important element for plant and bacteria growth. The response of bacteria to P transformation into adsorbed forms and their interaction with plants remain unclear. In this study, the mechanisms involved in P adsorption in plants and bacteria were analyzed by a RNA-seq technology. A phosphate-solubilizing bacterium (PSB) Acinetobacter sp. strain M01 was used in the transcriptome profiling of expressed genes and during interaction with melon (Cucumis melo L.). Results showed that the majority of genes related to cellular component and molecular function were up-regulated. The genes in the melon plant treated with M01 were down-regulated compared with those in the control. Genes for phenylalanine metabolism, amino acid, glycerolipid metabolism were identified in M01 DEGs related to transport and catabolism, carbohydrate metabolisms, and amino acid transport were marked in melon. This study provides an understanding of the gene interaction in PSB to fixed P and melon.
