What's a GeneRIF?

IAA8 plays its role in floral organ development by changes in jasmonic acid levels probably via its interaction with ARF6/8 proteins.
Title: A gain-of-function mutation in IAA8 alters Arabidopsis floral organ development by change of jasmonic acid level.
Data show that IAA8 is involved in lateral root formation, and that this process is regulated through the interaction with the TIR1 auxin receptor and ARF transcription factors in the nucleus.
