Abstract excerpt

GENERAL CONTROL NONDEREPRESSIBLE 5 (GCN5) is a histone acetyltransferase in Arabidopsis thaliana that plays a key role in various biological processes, including the development of flowers and inflorescences. We have shown that GCN5 genetically interacts with the CLAVATA (CLV) signalling pathway, potentially affecting gynoecium and inflorescence development by modulating auxin and cytokinin dynamics and...
