Disclosed herein are a sweetpotato SRD1 cDNA, a plant transformation vector carrying the same, and a transgenic plant comprising the vector. The thickening growth of storage roots of the transgenic sweetpotato prepared using the SRD1 cDNA is stimulated, increasing the number of storage roots by up to two times. Therefore, SRD1 according to the present subject matter is useful in the generation of transgenic root crops with high-numbered storage roots or early-maturing storage root plants.

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.

Antisense DNA of sweetpotato expansin cDNA and method for increasing storage root yield using the same

Disclosed herein are a sweetpotato expansin cDNA (IbExpansin), a plant transformation vector carrying the same, and a transgenic plant comprising the vector. The transgenic, prepared using the IbExpansin cDNA, outgrows the wild-type, thereby increasing in size and seed production up to three times. Thus, the gene is useful in the generation of highly productive transgenic plants for improvement in biomass and/or seed production.
