Exogenous bacterial cellulose induces plant tissue regeneration through the regulation of cytokinin and defense networks.

ABSTRACT: Regeneration is a unique feature of postembryonic development extensively observed in plants. The capacity to induce regeneration exogenously is limited and usually confined to meristematic-like tissues. We show that bacterial cellulose (BC), but not other structurally similar matrixes, induces postwounding regeneration in nonmeristematic plant tissues via a distinctive route to callus-mediated regenerative programs. The BC-specific program involves cytokinin operating concurrently with strongly activated plant biotic response genes to induce plant regeneration. A reactive oxygen species (ROS) burst, normally associated with defense responses, is sustained upon BC application, involving a network of tightly interconnected transcription factors, where WRKY8, known for regulating stress resp
