INOPERATIVE-TYPE GLUCORAPHASATIN SYNTHASE GENE AND USE OF SAME

摘要

Provided is a technique with which it is possible to produce a glucoraphasatin-deficient daikon line in a short time at high accuracy, as pertains to a technique for fundamentally overcoming the problems of deterioration of flavor, occurrence of radish odor, and deterioration of quality such as yellowing in processed daikon foods and the like. The present invention pertains to an inoperative-type glucoraphasatin synthase gene having (A) the characteristic of having a mutation associated with complete or partial deletion of the 2-oxoglutarate-iron(II)-dependent oxygenase domain in an encoded protein within an exon constituting a glucoraphasatin synthase gene, and (B) the characteristic of having the glucoraphasatin of the root portion deleted or substantially deleted when the glucoraphasatin synthase gene locus in the daikon genome is a homo-type of this inoperative-type gene.
