PcMYBs responded to 6-BA to regulate PcCKXs to promote germination of primary rhizome buds of Polygonatum cyrtonema Hua.

ABSTRACT: Polygonatum cyrtonema Hua is valued both as a precious traditional Chinese medicinal herb and as a prime example of a plant that bridges medicinal and culinary applications. Renowned for its significant medicinal and edible qualities, this botanical exemplifies a unique convergence of therapeutic and nutritional benefits. However, the primary rhizome of Polygonatum cyrtonema Hua development is difficult to germinate into seedlings in the same year. The germination of primary rhizome buds of P. cyrtonema can be promoted by treatment with exogenous hormone 6-BA, but the related regulatory mechanism is not clear. In this study, we found that the cytokinin oxidase (CKX) plays a key role in the germination of primary rhizome buds of P. cyrtonema. PcCKX1,2,3 promoted the expression of dormancy p
