Disease relevance of Plant Viruses

  • The identification of this symptom-modulating RNA as a co-linear deletion mutant of the helper virus genome establishes it as the first definitive defective interfering RNA (DI RNA) to be identified in association with a plant virus [1].
  • Many of the residues that the TMV read-through domain and the segmented plant viruses have in common are also conserved in a read-through domain found in the nonstructural polyprotein of the animal alphaviruses Sindbis and Middelburg [2].
  • The three-dimensional structure of an siRNA bound to the tombusvirus p19 protein--a suppressor of gene silencing--provides a first glimpse into how plant viruses can defeat their host's anti-viral RNAi defenses [3].
  • METHODS: An infectious plant virus clone, p35SZYMV2-26, that contains the full-length cDNA to the genomic RNA of a Taiwan isolate of ZYMV, driven by the cauliflower mosaic virus 35S promoter, was engineered as an in vivo viral vector to express Dermatophagoides pteronyssinus group 5 allergen (Der p 5) in cucurbit species [4].
  • The 3a movement protein (MP) of a plant virus, Cucumber mosaic virus (CMV), forms ribonucleoprotein (RNP) complexes with viral RNA, capable of trafficking from cell-to-cell throughout the infected plant only in the presence of the CMV capsid protein (CP) [5].

High impact information on Plant Viruses

  • Biochemical and mutational analysis of a plant virus polyprotein cleavage site [6].
  • Transgenic plants expressing PAP are resistant to a broad spectrum of plant viruses [7].
  • Induction of HSP70 and polyubiquitin expression associated with plant virus replication [8].
  • To test the possibility of engineering a broad type of resistance to plant viruses, we expressed the antisense RNA for tobacco SAHH in transgenic tobacco plants [9].
  • The natural role of PTGS seems to be as a defence against plant viruses, so what first appeared to be RNAs on the attack may now be considered RNAs on the defense [10].
