Abstract

After providing a picture of the global transcriptomic changes of grapevine responses to “stolbur” phytoplasma, the recovery status and molecular responses to the phytoplasma and virus co-presence were analyzed. NimbleGen® Vitis vinifera genome arrays were used. Lower transcript abundance of the genes involved in photosynthesis, trehalose, phospholipids was observed in response to the presence of “stolbur” phytoplasma. The expression of the genes involved in tetrapyrrole increased. The recovered plants showed that the transcripts involved in ATP synthesis and amino acid metabolism, secondary metabolism and biotic stress-related pathways increased. Recovery was associated with tetrapyrrole pathway repression. Co-infection with viruses induced the genes involved in the hormone categories (cytokinin, gibberellin, salicylic acid and jasmonates).
