Involved in immunity against bacterial infection and in non-host resistance (PubMed:20360018). Required for embryo development (PubMed:17915010). Required for systemic acquired resistance, but functions in an salicylic acid-independent manner (PubMed:20360018). Required for bacterium-triggered stomatal closure response (PubMed:21998587). Not up-regulated by pathogen infection. Reduced growth, pale or yellow leaves, frequent enations and pollen defect resulting in sterility. Enhanced susceptibility to bacterial infection. This protein was called 'ILITYHIA' after the Greek goddess of childbirth. Unlike other GCN1 homologs, ILA is not a component of the MOS4-associated complex (MSC), a protein complex with homology to the nineteen complex (NTC) in yeast and human. Belongs to the GCN1 family.
