BAK1 and glycogen storage disease VI: We found that PVY dsRNA could trigger expression of a range of classical PTI-related genes such as WRKY29 (WRKY transcription factor 29; a molecular marker of PTI; [42]), RbohD (respiratory burst oxidase homolog D; [43], EDS5 (enhanced disease susceptibility 5; [44]), SERK3 (somatic embryogenesis receptor kinase 3) encoding brassinosteroid-insensitive 1-associated receptor kinase 1 (BAK1) [45]), and PR-1b (pathogenesis-related gene 1b; [42]) (Figure 3A–E).
