Genomic sequencing has vastly expedited our understanding of bacterial functions. However, the genomes of many plant-growth-promoting bacteria (PGPB) have yet to be sequenced and contextualized. To this end, I report the sequenced genome of a PGPB-Caulobacter segnis CBR1-and contextualize its genomic features with the genomic features of sequenced Caulobacter strains. Moreover, I demonstrate that the CBR1 genome harbors genomic features that have been shown to be necessary for select Caulobacter strains to enhance the growth and development of Arabidopsis plants. Together, these findings will help guide future investigations that seek to understand the molecular factors undergirding the positive interactions between plants and microbes.
基因组测序极大地加速了我们对细菌功能的理解。然而，许多植物促生菌（PGPB）的基因组尚未被测序和背景化。为此，我报告了一个 PGPB-Caulobacter segnis CBR1 的测序基因组，并将其基因组特征与已测序的 Caulobacter 菌株的基因组特征进行了对比。此外，我证明了 CBR1 基因组具有一些基因组特征，这些特征对于某些 Caulobacter 菌株增强拟南芥植物的生长和发育是必要的。这些发现将有助于指导未来的研究，以了解植物和微生物之间正向相互作用的分子基础。
