Pseudomonas spp. make up 1.6% of the bacteria in soil and are found throughout world. More than 140 species this genus have been identified, some beneficial to plant. Several family Pseudomonadaceae, including Azotobacter vinelandii AvOP, stutzeri A1501, DSM4166, szotifigens 6HT33bT, sp. strain K1 can fix nitrogen from air. The genes required for these reactions organized a fixation island, obtained via horizontal gene transfer Klebsiella pneumoniae, stutzeri, vinelandii. Today, island is conserved different geographical locations, which, turn, evolved deal with geo-climatic conditions. Here, we summarize molecular mechanisms behind Pseudomonas-driven plant growth promotion, particular focus on improving performance at limiting (N) N content. We describe Pseudomonas-plant interaction strategies soil, noting that denitrification, ammonification, secondary metabolite signaling only marginally explored. Plant promotion dependent abiotic conditions differs sufficient deficient N. controls responses not fully elucidated. suggest superposition transcriptome, proteome, metabolome data their integration phenotype development through time will help fill gaps. aim review knowledge point possible agricultural solutions.
