Dr Max Newbert and Dr John Walsh have prepared videos on the outcomes of their BBSRC Crop Improvement Research Club (CIRC) project on exploiting sources of plant virus resistance for deployment in oilseed rape. Dr Graham Teakle and Dr Guy Barker were project co-investigators and Dr Adam Baker was the PDRA. Sources of resistance were identified in oilseed rape and lines of the diploid progenitors of oilseed rape; QTLs associated with the three resistance sources have been mapped. All three resistances have been shown to be effective against viral isolates representing the different genetic groups of the virus. The diversity of the virus across Europe has been investigated with 179 whole genomes sequenced, detailed phylogenetic analyses performed, new weed hosts identified and a full-length infectious clone of the virus generated.
