PIK3C2A and infection: To further confirm whether the expression of AcoCPK genes were influenced by different abiotic stresses, qRT-PCR experiments were performed to analysis the CPK gene family members expression patterns in response to different treatments, including cold, heat, salt stress, drought stress and (Dysmicoccus brevipes) infection (Figs. 4, 5 and 6, Additional file 10: Table S7, Additional file 11: Table S8, Additional file 12: Table S9, Additional file 13: Table S10 and Additional file 14: Table S11).
