The emergence of drug resistant pathogenic bacteria is increasingly challenging conventional antibiotics. Plant derived flavonoids are always considered as potential alternatives to antibiotics due to their antimicrobial properties. However, the molecular mechanisms by which flavonoids inhibit pathogenic microorganisms growth are not fully understood. In order to better understand the inhibitory mechanism of flavonoids, two flavonoids were used to incubate Klebsiella pneumoniae ATCC700603. After incubation for 4 hours, both the metabolomic and transcriptomic analysis were performed. In present study, 5,483 genes and 882 metabolites were measured. Compared to wild control, the Rutin and Luteolin induced 507 and 374 differentially expressed genes (DEGs), respectively. However, the number of differential abundant metabolites (DAMs) were the same. The correlation between DEGs and DAMs were studied. The top 10 correlated DEGs and DAMs were identified in each comparative groups. Our results showed that, compared to Luteolin, Rutin induced the accumulation of metabolites and suppressed genes expression. Our results provided an explanation for the disparate effects of two flavonoids and demonstrated the inhibitory mechanism of Rutin on strain growth.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
