Evidence Snippets

Though many natural and synthetic compounds exhibit auxin-like activity in bioassays, indole-3-acetic acid (IAA) is recognized as the key auxin in most plants.

Linked Claims

Claim 1review summarysupports2005Source 1DOI PubMed

Auxin signaling is mediated at least in large part by an SCFTIR1 E3 ubiquitin ligase complex that accelerates Aux/IAA repressor degradation in response to IAA, thereby altering gene expression.

Claim 2review summarysupports2005Source 1DOI PubMed

Auxin transport from shoot to root is necessary for normal development, and more localized transport is needed for tropic responses.

Claim 3review summarysupports2005Source 1DOI PubMed

IAA is synthesized through tryptophan-dependent and tryptophan-independent routes, but none of these pathways is fully elucidated in the review's framing.

Claim 4review summarysupports2005Source 1DOI PubMed

Indole-3-acetic acid is recognized as the key auxin in most plants.

Claim 5review summarysupports2005Source 1DOI PubMed

Plants can obtain IAA by beta-oxidation of IBA or by hydrolyzing IAA conjugates, and can permanently inactivate IAA by conjugation and direct oxidation.
