The -transgenic plants exhibit upregulated and gene expression.

root oncogenic locus B () is known to induce hairy roots along with triggering several physiological and morphological changes when present as a transgene. However, it is still unknown how this gene triggers these changes within the plant system. In this study, the effect of , when present as a transgene, was assessed on the gene expression levels of auxin response factors (s)-transcription factors which are key players in auxin-mediated responses. The goal was to uncover Auxin/-driven transcriptional networks potentially active and working selectively, if any, in transgenic background, which might potentially be associated with hairy root development. Hence, the approach involved establishing -transgenic plants, selecting s (Nts) for context-relevance using bioinformatics followed by gene expression profiling. It was observed that out of the chosen Nts, Nt and Nt exhibited a consistent pattern of gene upregulation across organ types. In order to understand the significance of these selective gene upregulation, ontology-based transcriptional network maps of the differentially and nondifferentially expressed s were constructed, guided by co-expression databases. The network maps suggested that Nt-Nt might have major deterministic, underappreciated roles to play in root development in a -transgenic background-as observed by higher number of "root-related" biological processes present as nodes compared to network maps for similarly constructed other non-differentially expressed s. Based on the inferences drawn, it is hypothesized that , when present as a transgene, might drive hairy root development by selective induction of Nt and Nt, suggesting a functional link between the two, leading to the specialized and characteristic -associated traits.
