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.
Claims3
A method for inducing abortion or deformation of a plant seed, comprising inducing the plant seed by a VvDUF642 protein or a nucleic acid molecule encoding the VvDUF642 protein,
- wherein the VvDUF642 protein is increased in activity in the plant seed,
- wherein the nucleic acid molecule encoding the VvDUF642 protein is overexpressed in the plant seed,
- wherein the amino acid sequence of the VvDUF642 protein is set forth in SEQ ID NO:
- 1,
- wherein a sequence of the nucleic acid molecule encoding the VvDUF642 protein is set forth in SEQ ID NO:
- 2, and
- wherein the plant seed is a grape seed, an Arabidopsis seed, or a tomato seed.
