Summary for Patent: 6,861,517
Title: | Nucleic acid fragments, recombinant vector containing the same and method for promoting the expression of structural gene by using the same |
Abstract: | Nucleic acid fragments having activities to prominently promote expression of structural genes located downstream thereof are disclosed. The nucleic acid fragment according to the present invention is an isolated nucleic acid fragment having the nucleotide sequence shown in SEQ ID NO: 1 in Sequence Listing or an isolated nucleic acid fragment (excluding the nucleic acid having the nucleotide sequence shown in SEQ ID NO: 3 in Sequence Listing) having the same nucleotide sequence as shown in SEQ ID NO: 1 except that one or a plurality of nucleotides are substituted or deleted, or except that one or a plurality of nucleotides are inserted or added, which has an activity to promote expression of a structural gene located downstream of said nucleic acid fragment. |
Inventor(s): | Ueki; Jun (Sizuoka, JP) |
Assignee: | Japan Tobacco Inc. (Tokyo, JP) |
Application Number: | 09/600,602 |
Patent Claims: | 1. An isolated nucleic acid no more than 120 nucleotides in length and comprising the nucleotide sequence shown in SEQ ID NO: 1 and that hybridizes to a polynucleotide having
a sequence that is the complement of SEQ ID NO: 3 under conditions equivalent to 5.times. Denhardt's solution, 6.times.SSC, 0.5% to 0.1% SDS, at a temperature from 50 to 65.degree. C., and which has activity to promote expression in a cell of a
structural gene located downstream of said nucleic acid.
2. The nucleic acid according to claim 1, consisting of a polynucleotide having the sequence of SEQ ID NO: 1. 3. A nucleic acid comprising a plurality of nucleic acids according to claim 1 or 2 that are ligated. 4. A plant, or progeny thereof, comprising a recombinant vector comprising a nucleic acid no more than 120 nucleotides in length and comprising the nucleotide sequence shown in SEQ ID NO: 1 that hybridizes to a polynucleotide having a sequence that is the complement of SEQ ID NO: 3 under conditions equivalent to 5.times. Denhardt's solution, 6.times.SSC, 0.5% to 0.1% SDS, at a temperature from 50 to 65.degree. C., and which has activity to promote expression in a cell of a structural gene located downstream of said nucleic acid and a structural gene located downstream of said nucleic acid whose expression in a cell is promoted by said nucleic acid. 5. A plant, or progeny thereof, comprising at least one polynucleotide no more than 120 nucleotides in length and comprising the nucleotide sequence shown in SEQ ID NO: 1 that hybridizes to a polynucleotide having a sequence that is the complement of SEQ ID NO: 3 under conditions equivalent 5.times. Denhardt's solution, 6.times.SSC, 0.5% to 0.1% SDS, at a temperature from 50 to 65.degree. C., and which has activity to promote expression of a structural gene located downstream of said nucleic acid, wherein said at least one polynucleotide is inserted into an intron of a structural gene. |
