“…Additionally, we obtained data supporting ubiquitinylation, SUMOylation, N ‐glycosylation, O ‐GlcNAcylation, acylation, S ‐nitrosylation and lysine acetylation events at 16 094 sites in 7238 proteins identified in large‐scale proteomic studies from the literature (Miller et al ., , ; Hemsley et al ., ; Kim et al ., ; Svozil et al ., ; Hu et al ., ; Johnson and Vert, ; Walton et al ., ; Xu et al ., , ; Koskela et al ., ; Liu et al ., ; Majeran et al ., ; Rytz et al ., ; Zeng et al ., ) (Table ). We also collected data supporting 19 043 mapped phosphorylation sites in 5783 proteins resulting from quantitative phosphoproteomics studies (Benschop et al ., ; Nühse et al ., ; Mithoe et al ., ; Zhang et al ., , ; Chen and Hoehenwarter, ; Minkoff et al ., ; Roitinger et al ., ; Cho et al ., ; Bhaskara et al ., ; Wang et al ., ) (Table ). To our knowledge, this is the most complete repository of Arabidopsis PTMs to date.…”
