A single viral amino acid shapes the root system architecture of a plant host upon virus infection.

ABSTRACT:

Background

Grapevine fanleaf virus (GFLV) is one of the most detrimental viral pathogens of grapevines worldwide but no information is available on its effect on the root system architecture (RSA) of plant hosts. We used two wildtype GFLV strains and their single amino acid mutants to assess RSA traits in infected Nicotiana benthamiana and evaluate transcriptomic changes in host root gene expression in replicated time course 3'RNA-Seq experiments. Mutations targeted the multi-functional GFLV-encoded protein 1E^Pol*/Sd, a putative RNA-dependent RNA polymerase and determinant of foliar symptoms in N. benthamiana plants.

Results

Plant infection with wildtype GFLV strain GHu and mutant GFLV strain F13 1E^Pol _G802K, both carrying a lysine in positio
