Endogenous mechanisms to restrict organ regeneration in plants
Plant Regeneration and Morphogenesis ・ Associate Professor ・ Momoko Ikeuchi
Plants have an outstanding regenerative capacity, which enable them to establish entire individuals from tissue explants. Tissue culture is an effective way to stimulate regenerative responses of plants, where explants are aseptically incubated with exogenous hormone application. Although some plant species poorly regenerate in tissue culture condition, endogenous mechanisms to restrict regenerative responses remain largely unclear. In this article, I will briefly explain our recent discovery on the repressive regulation on shoot regeneration in plants.

Figure2: WOX13 specifically regulates distinct regenerative responses.
Figure3: Shoot regeneration is enhanced in wox13 mutant. In addition, highly expanded cells are missing in wox13 mutant. Scale bar = 1 mm.
