Abstract:

【Objective】To explore the plant growth promotion function of a novel strain Pontibacter kalidii XAAS-72^T, and investigate the potential functional genes. 【Methods】The strain whole genome was sequenced, and the composition of function genes were analyzed. A candidate gene related to ACC deaminase synthesis was obtained, and the enzyme protein characteristics were predicted. 【Results】The results showed that the growth of wheat seed treated with Pontibacter kalidii XAAS-72^T was promoted significantly in pots.The genome length of strain XAAS-72 (accession no. CP111079) was 5,054,860 bp, containing one circular plasmid. A total GC content was 54.52%, and the number of annotated genes was 4,391, coding for 4,261 proteins. A variety of resistance and growth-promoting related genes was observed. It had the highest similarity of 72.48% to the ACC deaminase of Pontibacter sp. BAB1700. It an unstable hydrophilic protein, with none of transmembrane structure and signal peptide structure. 【Conclusion】Pontibacter kalidii XAAS-72^T harbors a lot of genes related to the stress resistance and the plant growth-promoting.
