    • The present invention relates to inducible transcription control sequences for the regulation of gene expression. Specifically, it relates to an transcription control sequence comprising at least two tet operator sequence motifs allowing the binding of tetracycline-dependent transcriptional regulators, wherein each of the said tetracycline-dependent transcriptional regulators binds with respect to its neighbour to an opposite face of the DNA helix, and a minimal promoter comprising a TATA box which is linked at its 5′ end to a general transcription factor binding site. Further, the present invention relates to a vector, a host cell, a plant or a non-human transgenic animal comprising the said transcription control sequence. Also contemplated is a method for regulating the expression of a nucleic acid sequence being operatively linked to the transcription control sequence of the present invention in a host cell, a plant or a non-human transgenic animal.

    • We have developed a versatile plant viral vector system based on Alternanthera mosaic virus (AltMV), suitable for infection by agroinfiltration or in vivo T7 transcripts from the same clone; agroinfection is enhanced by coinfiltration of a T7 RNA polymerase construct. Variants adapted for efficient protein expression, or for virus-induced gene silencing (VIGS), are based on a specific amino acid substitution (L88P) in the triple gene block 1 (TGB1) protein affecting RNA silencing suppression. A bipartite delivery system developed for AltMV delivers replicase (RdRp) functions separately from movement and encapsidation (TGB and coat protein, CP) functions by agroinfiltration, resulting in precise recombination of RdRp and TGB-CP constructs in planta. The bipartite delivery system has potential for high throughput protein expression or VIGS with the appropriate TGB1 variant, for hosts including Nicotiana benthamiana and Arabidopsis thaliana. Equivalent TGB1 substitutions in other potexviruses also reduced RNA silencing suppression, demonstrated with Potato virus X.
