Identification of direct target genes of the tomato FRUITFULL homologs during ripening by promoter ChIP-chip

ABSTRACT: Tomato (Solanum lycopersicum) has two MADS-box FRUITFULL homologs, FUL1 and FUL2, both of which are able to interact with the master ripening regulator RIN. Here, we performed chromatin immunoprecipitation coupled with a DNA microarray (ChIP-chip) for the 2-kb upstream putative promoters of whole tomato predicted genes (ITAG2) for a large-scale identification of the direct target genes of FUL1 and FUL2 during ripening. The ChIP-chip with antibodies of FUL1 and FUL2 identified 1,877 and 1,919 of FUL1- and FUL2-binding sites, respectively, each of which was assigned a significantly high peak score (FDR<0.05) in at least two of the three biologically independent analyses. Using the information about genomic position of the FUL1- and FUL2-binding sites, we found 1,943 and 2,051 potential dire
