| 摘要 |
<p>The present invention provides, inter alia, a recombinant polynucleotide, comprising a transcriptional regulatory region and a region contiguous therewith and under the transcriptional control thereof, wherein the contiguous region comprises the sequence depicted in SEQ ID No. 1 or a sequence complementary thereto or a part of the sequence or complement, characterized in that the sequence, complement or part is modified (i) by removal therefrom of translational-start encoding codons, or mutation of such codons so that they do not encode translational start or stop codons; or (ii) by insertion or deletion of nucleotides 3' of the translational start encoding codon so that the translational reading frame of the thus encoded RNA is different to that of the unmodified sequence, complement or part. The modified sequence, complement or part is capable of conferring upon plants resistance or tolerance to tospoviruses - typified by TSWV.</p> |
