Meristematic characteristics of tumors initiated by Agrobacterium tumefaciens in pea plants

摘要: It is known that two key groups of plant hormones—auxins and cytokinins—play an important role in tumor development. The formation Agrobacterium-induced tumors results from the horizontal transfer bacterial oncogenes involved biosynthesis these hormones genome. transcriptional factors development poorly investigated. can be assumed associated with abnormal cell proliferation controlled by same set transcription control normal and, particular, regulate meristem activity. In present study, we analyzed histological organization distribution proliferating cells induced Agrobacterium tumefaciens on pea hypocotyls. addition, expression a meristem-specific genes tumefaciens-induced was analyzed. general, our indicate meristematic structures are A. such increased gene regulating root apical meristem—the WOX5 gene.
