The plant hormone auxin regulates growth and development by modulating the stability of auxin/indole acetic acid (Aux/IAA) proteins, which in turn repress auxin response factors (ARFs) transcriptional regulators. In transient assays performed in immature sunflower embryos, we observed that the Aux/IAA protein HaIAA27 represses transcriptional activation by HaHSFA9, a heat shock transcription factor (HSF). We also found that HaIAA27 is stabilized in immature sunflower embryos, where we could show ...[more]
