Genome-wide identification of C2H2 zinc-finger genes and their expression patterns under heat stress in tomato (Solanum lycopersicum L.).

ABSTRACT: The C2H2 zinc finger protein (C2H2-ZFP) transcription factor family regulates the expression of a wide variety of genes in response to various developmental processes or abiotic stresses; however, these proteins have not yet been comprehensively analyzed in tomato (Solanum lycopersicum). In this study, a total of 104 C2H2-ZFs were identified in an uneven distribution across the entire tomato genome, and include seven segmental duplication events. Based on their phylogenetic relationships, these genes were clustered into nine distinct categories analogous to those in Arabidopsis thaliana. High similarities were found between the exon-intron structures and conserved motifs of the genes within each group. Correspondingly, the expression patterns of the C2H2-ZF gene
