Although the importance of light for tomato plant yield and edible fruit quality is well known, the PHYTOCHROME INTERACTING FACTORS (PIFs), main components of phytochrome-mediated light signal transduction, have been studied almost exclusively in  Arabidopsis thaliana . Here, the diversity, evolution and expression profile of  PIF  gene subfamily in  Solanum lycopersicum  was characterized. Eight tomato  PIF loci  were identified, named  SlPIF1a ,  SlPIF1b ,  SlPIF3 ,  SlPIF4 ,  SlPIF7a ,  SlPIF7b ,  SlPIF8a  and  SlPIF8b . The duplication of  SlPIF1 ,  SlPIF7  and  SlPIF8  genes were dated and temporally coincided with the whole-genome triplication event that preceded tomato and potato divergence. Different patterns of mRNA accumulation in response to light treatments were observed during seedling deetiolation, dark-induced senescence, diel cycle and fruit ripening.  SlPIF4  showed similar expression profile as that reported for  A .  thaliana  homologs, indicating an evolutionary conserved function of PIF4 clade. A comprehensive analysis of the evolutionary and transcriptional data allowed proposing that duplicated  SlPIFs  have undergone sub- and neofunctionalization at mRNA level, pinpointing the importance of transcriptional regulation for the maintenance of duplicated genes. Altogether, the results indicate that genome polyploidization and functional divergence have played a major role in diversification of the  Solanum PIF  gene subfamily.
