Genetic modification of rootstocks for disease resistance in rose. - HH1020THN(1)

Genetically Engineered Acquired Resistance (GEAR) will be introduced into a common rose rootstock using transformation technology such that resistance will be transmissible to any grafted scion. Resistance will be for a wide range of plant pathogens. This reflects the recommendations of the Crop Protection Review(s) which identified a need to increase disease resistance in scion rose but via modification of the rootstock. This would have wide applicability to the rose industry. Rosa laxa is identified as the predominant rootstock and hence the main focus. Through R. laxa, in turn, a wide range of grafted, but normal, scion material is the ultimate target for the acquisition of broad-based systemically transmitted disease resistance from the rootstock. Scion growth and development will also be evaluated when using engineered rootstocks with enhanced root development capacity. Concomitant improvements in disease resistance for the R. laxa rootstock per se are anticipated. Plant materials will be made available to the rose industry. Results will be published in peer-reviewed scientific journals.
To establish a broadly applicable approach, based on the principle of Genetically Engineered Acquired Resistance (GEAR) to introduce durable, stable resistance against a range and number of plant pathogens into rose.
