#hda19

[whats-in-a-sentence]

JA acts through a conserved ubiquitin ligase-based signaling mechanism that bears close resemblance to those described for auxin and gibberellin (Figure 23.19). (...) Two additional proteins and two histone deacetylase enzymes (HDA6 and HDA19) act as co-repressors asking with the JAZ-COI1 complex and are instrumental in maintaining the chromatin in an inactive state (see Figure 23.19). The binding of JA-Ile to the JAZ-COI1 co-receptors leads to the ubiquitination of JAZ by the SCF^(COI1-JA-Ile) complex, followed by JAZ degradation via the 26S proteasome (see Figure 23.19).

The HDA19 histone deacetylase complex is involved in the regulation of flowering time in a photoperiod-dependent manner.
