Transcription activator that binds DNA in a sequence-specific manner, 5'-GAAATTTTGG-3', to promote the expression of target genes (PubMed:20921422, PubMed:21615571, PubMed:23153277). Recruited to the promoter of ICS1 and other defense-related genes (e.g. PR1 and SID2) in response to both biotic (e.g. Pseudomonas syringae pv. maculicola ES4326) and abiotic stresses (e.g. UV-B), thus triggering slow defense responses by stimulating salicylic acid (SA) biosynthesis. Required for basal and systemic acquired resistance to P. syringae pv. maculicola and Hyaloperonospora arabidopsidis (PubMed:20921422, PubMed:21615571). (Microbial infection) Interacts with V.dahliae SCP41. Induced slowly by Pseudomonas syringae p.v. maculicola ES4326 and by microbe-associated molecular patterns (MAMPs) such as flg22 in both local and systemic leaves. Compromised basal resistance and systemic acquired resistance (SAR) induced by Pseudomonas syringae p.v. maculicola ES4326 toward Hyaloperonospora arabidopsidis Noco2. Plants lacking both SARD1 and CBP60G fail to accumulate salicylic acid (SA) and to express PR1 and SID2 upon both biotic and abiotic stresses. Belongs to the plant ACBP60 protein family. Truncated N-terminus.
