GO terms were assigned to proteins by manually transferring the GO terms for Swiss‐Prot IDs using the UniProt‐GOA database downloaded on 13 March 2016 (Huntley et al., 2015). KEGG K numbers were assigned to all predicted proteins using BLASTKOALA (taxonomy group: Plants, KEGG GENES database: family_eukaroytes) (Kanehisa et al., 2016).
