PstSCAB and SapBCDF are putrescine exporters in Proteus mirabilis [PDF]

Microbiology Spectrum
Proteus mirabilis is a cause of urinary tract infection. Putrescine, an aliphatic amine, acts as a messenger molecule during P. mirabilis urothelial invasion. Inhibition of putrescine-mediated cell-cell communication in P.

The gene encoding ornithine decarboxylase for putrescine biosynthesis is essential for the viability of Fusobacterium nucleatum [PDF]

Journal of Bacteriology
Fusobacterium nucleatum is a Gram-negative anaerobe associated with periodontitis and colorectal cancer. It secretes putrescine, a polyamine that promotes biofilm formation by oral co-colonizers and enhances the proliferation of cancer cells.

Improvement of putrescine production through the arginine decarboxylase pathway in Escherichia coli K-12

AMB Express, 2021
In the bio-based polymer industry, putrescine is in the spotlight for use as a material. We constructed strains of Escherichia coli to assess its putrescine production capabilities through the arginine decarboxylase pathway in batch fermentation.

INFLUENCE OF POST-SET SPRAY APPLICATION OF PUTRESCINE, KNO3 AND CPPU ON FRUITS NUMBER, DROP RATE, RETENTION AND QUALITY OF MANGO CV. ALPHONSO [PDF]

Journal of Plant Production, 2000
This investigation was conducted on 20 year old mango trees ( Mangifera Indica L. ) cultivar Alphonso. Panicles were sprayed two weeks after fruit set with putrescine at 150, 300 or 450 ppm, KNo3 at 0.5, 1 or 2% or CPPU at 5, 10 or 15 ppm.
