show Abstracthide AbstractRNA-sequencing was performed on grape phylloxera single founder lineages of two larval stages (L1 and L2-3) belonging to two different biotypes (A and C) feeding on V. vinifera cv. Riesling and the rootstock Teleki 5C (V. berlandieri x V. riparia), respectively. The goal of the analysis was to identify genes commonly modulated during development between biotypes and at the same time specific genes related to each biotype.
