GENOME-WIDE IDENTIFICATION AND ANALYSIS OF GENES ENCODING PHD-FINGER PROTEIN IN TOMATO
XUEJIN CHEN1,2, SIKANDAR HAYAT1 AND ZHIHUI CHENG1*
Abstract: The PHD-finger proteins are conserved in eukaryotic organisms and are involved in a variety of important functions in different biological processes in plants. However, the function of PHD fingers are poorly known in tomato (Solanum lycopersicum L.). In current study, we identified 45 putative genes coding PHD-finger protein in tomato distributed on 11 chromosomes except for chromosome 8. Some of the genes encode other conserved key domains besides PHD-finger. Phylogenetic analysis of these 45 proteins resulted in seven clusters. Most PHD finger proteins were predicted to PML body location. These PHD-finger genes displayed differential expression either in various organs, at different development stages and under stresses in tomato. Our study provides the first systematic analysis of PHD-finger genes and proteins in tomato. This preliminary study provides a very useful reference information for PHD-finger proteins in tomato. They will be helpful for cloning and functional study of tomato PHD-finger genes.
Key words: Tomato, PHD-finger, Identification, Analysis.
