What's a GeneRIF?
  1. These results show that the AlgR phosphorylation state can directly, as well as indirectly, modulate the expression of iron acquisition genes that may ultimately impact the ability of Pseudomonas aeruginosa to establish and maintain an infection.
    Title: Pseudomonas aeruginosa AlgR Phosphorylation Status Differentially Regulates Pyocyanin and Pyoverdine Production.
  2. In conclusion, this study for the first time indicates that AlgR directly binds to rsmZ to regulates the expression of lipA via regulating transcription of rsmZ, and mainly regulates the expression of lipA at transcriptional level in P. protegens Pf-5.
    Title: The Pseudomonas transcriptional regulator AlgR controls LipA expression via the noncoding RNA RsmZ in Pseudomonas protegens Pf-5.
  3. AlgR controls the levels of c-di-GMP synthesis via direct regulation of mucR, which encodes a diguanylate cyclase.

  4. AlgZ and algR transcription involves multiple factors at multiple start sites that control individual gene expression.

  5. These results indicate that phosphorylated AlgR-P has increased affinity for the rhlA promoter and is required for the coordinate activation of twitching motility, rhamnolipid production, and swarming motility in P. aeruginosa.

  6. Strains lacking AlgR or the putative AlgR sensor AlgZ produced significantly less hydrogen cyanide than did a nonmucoid isogenic parent.

  7. Findings indicate that AlgR is essential for proper pilin localization and that phosphorylation of AlgR results in direct activation of the fimU-pilVWXY1Y2E operon, which is required for the assembly and export of a functional type IV pilus.
