Numbers of ABI3 target gene candidates identified by ChIP-chip (bound promoters) and transcriptome analysis (regulated genes). The candidate genes were subdivided according to their expression in seeds: Genes with seed MI > 31 exhibit a strong seed-specific expression (definition of MI see below); genes with MI < 31 are here considered as non-seed-specific genes; NA, MI not available. The overlapping 42 genes are called core regulon. ChIP-chip was performed with chromatin isolated from wild-type seeds; transcript analysis was performed with transgenic seedlings transformed with an ABI3-inducible gene construct.
