A promoter cv20oxp which regulates the integument-specific expression of a gibberellin 20-oxidase gene in developing seeds of watermelon and a method for generating seedless fruits using the promoter

摘要

The present invention relates to a testa specific gene, which is isolated from the developing seed of iCitrullus lanatus/i, a promoter and a method for generating seedless fruits by using the promoter of the said testa specific gene. More specifically, the present invention provides a Cv20ox gene, gibberellin 20-oxidase(GA 20-oxidase) gene showing the tissue-specific expression pattern, which is strongly expressed in the integumental tissue at seed development of watermelon and is weakly expressed in the inner tissue of seed, a promoter regulating the integument-specific expression of the said gene and a method for generating seedless fruits by introducing plant growth regulation gene ligated to the said promoter and regulating the overexpression of plant growth regulation composition in the testa.
