The present invention relates to a
novel gene, IbENOD93, and transgenic plants using the same. More specifically, the present invention provides an IbENOD93
gene, an
open reading frame (ORF) of the IbENOD93
gene, a recombinant vector comprising the
gene or the ORF, and a transformant transformed with the vector. Moreover, the present invention provides a composition for enhancing root thickening growth and promoting maturation in a
plant having storage root(s). Furthermore, the present invention provides a method for producing a transgenic
plant having storage root(s) with enhanced thickening growth, and a method for regulating or enhancing root thickening growth and maturation in a
plant having storage root(s). According to the present invention, it is possible to promote the thickening growth of storage roots as well as the growth of aerial part. Therefore, the present invention can be effectively used to promote the thickening growth of storage roots of high-value
root crops such as
ginseng, sweet potato, etc. and to produce early-maturing transgenic plants.
