N2 - © 2015, Pleiades Publishing, Inc. It is known that two key groups of plant hormones—auxins and cytokinins—play an important role in plant tumor development. The formation of Agrobacterium-induced tumors results from the horizontal transfer of bacterial oncogenes involved in the biosynthesis of these hormones in the plant genome. The role of transcriptional factors in plant tumor development is poorly investigated. It can be assumed that tumor development associated with abnormal cell proliferation can be controlled by the same set of transcription factors that control normal cell proliferation and, in particular, transcription factors that regulate meristem activity. In the present study, we analyzed the histological organization and distribution of proliferating cells in tumors induced by Agrobacterium tumefaciens on pea hypocotyls. In addition, the expression of a set of meristem-specific genes with Agrobacterium tumefaciens-induced tumor development was analyzed. In general, our results indicate that meris
