Bioinformatics Analysis of WRKY Gene Family in Tomato
We predicted the family members,physicochemical properties,gene classification,chromosome location,phylogenetic relationship and domain sequence conservation of WRKY transcription factor in tomato by bioinformatics methods.The results of WRKY transcription factor family classification and evolution in tomato showed that tomato SlWRKY family contained 81 members.They could be divided into 3 groups according to the WRKY domain and zinc finger structure.The second group could be divided into five subgroups according to the sequence of amino acids.The results of chromosomal localization showed that WRKY transcription factor distributed in all tomato chromosomes except chromosome 11.Gene structure Analysis showed that only SlWRKY19 and S1WRKY20 had no intron,other members all contained 2~5 introns.Conservative domain analysis showed that the tomato WRKY domain was highly conserved,with only 10 WRKYGQK mutations,which accounted for 10% of the WRKY family.
