Abstract
Disclosed herein are antisense DNA of a sweetpotato expansin (IbExpansin) cDNA, a plant transformation vector carrying the same, and a method for increasing storage root production using the same. The transgenic sweetpotatoes prepared using the antisense DNA of IbExpansin cDNA have storage root production increased by up to one and half times. Thus, the gene is useful in the generation of highly productive transgenic storage roots for the increase of bioethanol production.
Claims4
A method for increasing storage root production of sweetpotato, comprising:
- introducing an antisense DNA of IbExpansin cDNA into the sweetpotato, wherein the antisense DNA comprises the nucleotide sequence of SEQ ID NO.:
- 9, and wherein the sweet potato into which the antisense DNA is introduced produces an increased amount of storage root compared to a wild-type sweetpotato.
A method for preparing a transgenic sweetpotato with a capacity of increased storage root production, comprising:
- introducing an antisense DNA of IbExpansin cDNA into a sweetpotato to produce the transgenic sweetpotato plant, wherein the antisense DNA comprises the nucleotide sequence of SEQ ID NO.:
- 9.
