Disease relevance of PFL_2091

  • A transposon system based on Tn7 carrying the chiA gene (encoding chitinase) of Serratia marcescens was established [1].
  • The chitinase encoding Tn7-based chiA gene endows Pseudomonas fluorescens with the capacity to control plant pathogens in soil [1].
 

High impact information on PFL_2091

  • An increased toxic effect was observed when P. fluorescens 14::ptac-tox was combined with P. fluorescens carrying the Serratia marcescens chitinase gene chiA, under the control of the tac promoter, integrated into the chromosome [2].
  • Spontaneous pleiotropic mutants of P. fluorescens strain BL915 which fail to synthesize antifungal factors such as chitinase, cyanide, and pyrrolnitrin and exhibit altered colony morphology were isolated [3].
  • Production of chitinase, beta-1,3-glucanase, siderophores, salicylic acid (SA) and hydrogen cyanide (HCN) by P. fluorescens strains was evaluated [4].
 

Analytical, diagnostic and therapeutic context of PFL_2091

  • Northern blots of RNA from zones 1, 2, and 3 were probed with bean cDNAs for phenylalanine ammonia-lyase (PAL), chalcone synthase (CHS), chitinase (CHT), and lipoxygenase (LOX) [5].
