Production and fingerprinting of virus-free clones in a reflowering globe artichoke

Abstract

Most of the 24 viruses which infect globe artichokeare detrimental to the crop's performance and hamperthe development of a nursery activity in the respect of currentEU legislation. We describe a procedure to sanitize globeartichoke ''Brindisino'' from Artichoke Italian latent virus(AILV) and Artichoke latent virus (ArLV), while preservingits valuable early flowering trait. ArLV was successfullyeliminated by meristem-tip culture,whileAILVwas removedwhen two rounds ofmeristem-tip culture were spaced outwithin vitro thermotherapy. In vivo thermotherapy, followed bymeristem-tip culture, was also successful in producing virusfreematerial but was less efficient in terms of the number ofplants recovered post treatment. Due to the multi-clonalcomposition of the populations at present in cultivation, theselected and sanitised clones were fingerprinted by applyingmicrosatellite and AFLP (amplified fragment length polymorphism)markers.OneAFLP primer combination produced28 informative fragments used to evaluate genetic relatednessamong the clones in study. Our results demonstrates thatAFLP-based molecular fingerprinting enables to verify thetrue to clone correspondence in nurseries, ensure the effectivecorrespondence between the real and the declared identity of aclone, so that to avoid commercial frauds, and might representsa valuable tool for assessing somaclonal variationoccuring during 'in vitro' propagation
