Abstract Adventitious root formation poses a major constraint on the tissue culture and genetic transformation of Eucommia ulmoides. Micrografting offers a new method for the transplantation of genetic transformation, and its success depends on the formation of graft unions. This study used transgenic rootless test-tube seedlings as scions and seedlings from seed as rootstocks during micrografting to avoid the rooting issues that occur during tissue culture and to investigate the role of the EuEG1 gene in the graft healing process. We found that the EuEG1 gene is a vital regulator of graft, and its overexpression contributes to the survival of Eucommia… More >
