Abstract
The WRKY transcription factor gene family is known to be involved in plant defense against pathogens and in tolerance to different environmental stresses at different stages of development. The response mechanisms through which these genes act can be influenced by different phytohormones as well as by many trans- and cis-acting elements, making this network an important topic for analysis, but still something complex to fully understand. According to available reports, these genes can also perform important roles in pome species (Malus spp. and Pyrus spp.) metabolism, especially in adaptation of these plants to stressful conditions. Here, we present a quick review of what is known about WRKY genes in Malus and Pyrus genomes offering a simple way to understand what is already known about this topic. We also add information connecting the evolution of these transcription factors with others that can also be found in pomes.
