ESTs for this analysis were preferentially chosen among those showing significant similarity with genes related to response to infection and fruit quality characteristics in melon and other species, and included CTL1, EIF4A-2, EIF4E, EIN4, GA2OX1, HSP101, HSP70, IAA9, LSM1, LUT2, NCBP, SVP, HIR, TCH4, TIP4, TOM1, TOM2A, TOM3, UGE5 and WRKY70 (Table 9). This evidence concerns the gene TOM1 and infection.
