Abstract: The present disclosure relates to the field of genetic breeding, in particular, to methods and formulations for inducing abortion or deformation of plant seeds by a VvDUF642 gene. The result of the present disclosure shows that the VvDUF642 gene is continuously expressed at a high level in seedless varieties, but there is no significant change in expression in nucleated varieties. After the VvDUF642 gene is transformed into an Arabidopsis, Arabidopsis seeds are deformed. After the VvDUF642 gene is transformed into a tomato, it causes abortion of tomato seeds. The gene or protein can be used for the construction or screening of seed abortion grape varieties.
