Two additional proteins and two histone deacetylase enzymes (HDA6 and HDA19) act as co-repressors along with the JAZ–COI1 complex and are instrumental in maintaining the chromatin in an inactive state.

IAA synthesis

IAA biosynthesis is associated with rapidly dividing and growing tissues

Primary site of auxin synthesis are shoot apical meristem and young leaves

Root apical meristem also synthesize auxin

Young fruits an seeds also have high level of auxin
