Genome-wide analysis of the WRKY gene family unveil evolutionary history and expression characteristics in tomato and its wild relatives.

ABSTRACT: WRKY transcription factors (WRKYs) are one of the largest plant gene families in plants involved in various biotic and abiotic stress responses. Based on the conservation of WRKY proteins, we identified a total of 642 WRKYs in Amborella trichopoda (33), Vitis vinifera (64), Arabidopsis thaliana (48), Solanum lycopersicoides (88), S. pennellii (77), S. pimpinellifolium (80), S. lycopersicum var. cerasiforme (85), S. lycopersicum cv. Heinz1706 (85), and S. lycopersicum cv. M82 (82) genomes. Phylogenetic analysis clustered WRKYs from nine genomes above into two clusters (Cluster1 and Cluster2). Evolutionary analysis revealed that most of the WRKYs in tomato and its wild relatives were expanded after the whole genome triplication (
