indole-3-acetic acid | expression of ipdC is upregulated by indole-3-acetic acid, other auxins, and nutrient stress | Azospirillum brasilense | |
L-tryptophan | at low concentrations, Trp does not influence ipdC expression but 2fold induction is observed at 2.5 mM Trp | Azospirillum brasilense |
Cloned (Comment) | Organism |
---|---|
heterologous overexpression of a functional iaaC gene from strain Sp245 in strain SM confirms its role in controlling IAA biosynthesis and lowering ipdC expression which may be effected by dissociating indole-3-acetic acid-transcriptional regulator interactions in the 5'region | Azospirillum brasilense |
