|a Expression of the root oncogenic loci (rol) genes from Agrobacterium rhizogenes provokes multiple divergent effects on physiological properties in transgenic plants and cell cultures. Recently, the homolog of the rolB and rolC oncogenes, named Ib-rolB/C, has been identified in the genome of a naturally transgenic food crop, i.e. sweet potato. In this study, we revealed that the Ipomoea batatas genome contains two full-length copies of Ib-rolB/C. The expression level of Ib-rolB/C in leaves of sweet potato showed a clear age-dependent pattern and increased as leaves senesce. Moreover, dark-induced senescence strongly up-regulates transcription of the Ib-rolB/C gene. Though Ib-rolB/C shares homology with its counterparts in A. rhizogenes, this gene was not capable to induce hairy roots or tumors in kalanchoe and tobacco plants. The Ib-rolB/C gene induced early-flowering phenotype, altered leaf morphology, and promoted premature leaf senescence in transgenic Arabidopsis thaliana plants. At the same time, Ib-rolB/C did not affect root morphology and biomass. Our results suggest that Ib-RolB/RolC participates in both age- and dark-triggered leaf senescence programs
