|a The AT-HOOK MOTIF CONTAINING NUCLEAR LOCALIZED (AHL) transcription factors play important roles in regulating plant development and stress response. However, the AHL family genes have not been identified in tomato (Solanum lycopersicum) and their biological functions have not been elucidated. In this work, the gene families encoding AHLs were identified in tomato genome, and their physical and chemical characteristics, subcellular localization, gene expression profiles during fruit development and upon abiotic stimulus were investigated. Overall, a total of 18 AHL members were identified in tomato genome, phylogenetic analysis classified these SlAHL members into two clades, clade A (SlAHL1-8) and clade B (SlAHL9-18). Six clade A SlAHLs were detected to be subcellular localized in the nucleus. The transcripts of the representative clade A SlAHLs predominantly accumulated 10 days post anthesis (dpa) in tomato fruits, revealing an involvement of these SlAHLs in early fruit development. Furthermore, compared with clade B members, the transcripts of the clade A SlAHLs were more responsive to heat, drought, cold and salt stresses, suggesting that these SlAHLs may play major roles in response to abiotic stresses. Moreover, overexpression of SlAHL1 and SlAHL7 in Arabidopsis increased the sensitivity to ABA during seed germination and seedling stages. Overexpression of SlAHL1 inhibited seed germination while increased primary root elongation upon salt and drought stresses. Together, our work suggested that the clade A SlAHL genes may play an important role in response to abiotic stresses, which paving the way for future functional analysis of AHL genes in tomato and other Solanaceae species
