Other claims from this paper (8)
- Observation The two Pseudomonas iaa operons exceeded 90% sequence relatedness at iaaM and iaaH, with a sharp decline upstream of iaaM.
- Observation A third open reading frame was found downstream of iaaH.
- Intervention effect IAA production was undetectable in the iaaM insertion mutant.
- Observation The IAA-deficient mutant retained bean phylloplane colonization.
- Intervention effect The mutant caused bean symptoms similar to the parental strain.
- Intervention effect The mutant induced disease at a lower initial density than either IAA-producing strain.
- Intervention effect Syringomycin biosynthesis in the mutant was diminished relative to parental and restored strains.
- Mechanism The authors infer bacterial IAA synthesis regulates in planta growth and host interaction factors.
Phaseolus vulgaris
