Summary Asparagine (Asn, N )‐linked glycosylation within N glyco ‐X‐S/T; X ≠ P motif is a ubiquitously distributed post‐translational modification that participates in diverse cellular processes. In this work, N ‐glycosylation inhibitor was shown to prevent Phytophthora sojae growth, suggesting that N ‐glycosylation is necessary for oomycete development. We conducted a glycoproteomic analysis of P. sojae to identify and map N...
