The complete genome sequences of two grapevine virus L (GVL) isolates collected from the wine grape cultivar Blanc du Bois (Vitis spp.: 'Florida D 6-148'×'Cardinal') in Texas were determined. The two genome sequences (excluding the polyA tail) were each 7594 nucleotide long and 99.7% identical to each other, but they shared only ~74% identity with those of previously published GVL isolates. Further analysis showed that the two Texas GVL isolates also diverged significantly from previously published isolates of the virus in each of the five ORFs at both the nucleotide and amino acid level, indicating that they represent a new phylogroup of this virus.
