The auxin pathway is a target of pathogen attack. High auxin levels are correlated with increased disease development. Pathogens increase their chances of success through increased auxin biosynthesis and altered auxin transport. Plant hosts defend against this strategy by conjugating free auxin, inhibiting receptor production, and promoting accumulation of auxin transcriptional repressors. In counter-offensive strategies, pathogens target the host's ability to control auxin response.
