Regeneration is a unique feature of postembryonic development extensively observed in plants. The capacity to induce regeneration exogenously limited and usually confined meristematic-like tissues. We show that bacterial cellulose (BC), but not other structurally similar matrixes, induces postwounding nonmeristematic plant tissues via distinctive route callus-mediated regenerative programs. BC-specific program involves cytokinin operating concurrently with strongly activated biotic response genes regeneration. A reactive oxygen species (ROS) burst, normally associated defense responses, sustained upon BC application, involving network tightly interconnected transcription factors, where WRKY8, known for regulating stress shows clustering hierarchical prevalence. WRKY8 regulates BC-mediated ROS homeostasis, including superoxide anion accumulation, potentially promote cell proliferation after wounding. Collectively, our results demonstrate the cytokinin- ROS-associated responses can be targeted by application wound through alternative
