Other claims from this paper (5)
- Observation IAA accumulates in cereal plants during early Fusarium graminearum infection.
- Mechanism IAA has been suggested as a virulence factor that alters host nutrition and immunity.
- Observation Plant and fungal genomes are predicted to contain genes for L-tryptophan-dependent IAA biosynthesis.
- Association Low concentrations of these metabolites have been reported to stimulate IAA accumulation.
- Recommendation The authors recommend identifying fungal effectors involved in cereal IAA accumulation.
