Grapevine virome and production of healthy plants by somatic embryogenesis.

ABSTRACT: Grapevine (Vitis spp.) is a widespread fruit tree hosting many viral entities that interact with the plant modifying its responses to the environment. The production of virus-free plants is becoming increasingly crucial for the use of grapevine as a model species in different studies. Using high-throughput RNA sequencing, the viromes of seven mother plants grown in a germplasm collection vineyard were sequenced. In addition to the viruses and viroids already detected in grapevine, we identified 13 putative new mycoviruses. The different spread among grapevine tissues collected in vineyard, greenhouse and in vitro conditions suggested a clear distinction between viruses/viroids and mycoviruses that can successfully be exploited for their identification. Mycoviruses were absent in in vitro c
