    • 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.
    • 本发明尤其提供了一种重组多核苷酸,其包含转录调节区和与其连续的区域及其转录控制,其中连续区包含SEQ ID No.1所示的序列或其互补序列或 序列或补体的一部分,其特征在于修饰序列,补体或部分(i)通过从其中除去翻译起始编码密码子或这种密码子的突变,使得它们不编码翻译起始或终止密码子; 或(ii)通过插入或缺失翻译起始编码密码子的核苷酸3',使得如此编码的RNA的翻译阅读框与未修饰的序列,补体或部分的翻译读框不同。 修饰的序列,补体或部分能够赋予植物对烟草病毒的抗性或耐受性,以TSWV为代表。
