The growth hormone auxin has been implicated as a necessary factor in the development of different types of fruit. The perception of auxin is essential, especially in pea plants where two types of auxin are present, and the chlorinated form seems to be the more active one. The elegant and detailed work by Ozga et al. (2022) has shown how indole-3-Acetic acid (IAA), 4-chloro-indole-3-Acetic acid (4-Cl-IAA), gibberellin (GA), and ethylene contribute to pea seed development by dissecting the different tissues for the analysis of the response in addition to the interaction of pea auxin receptors with the Aux/IAA repressors, and identified a complex tissue-specific hormonal network.
