Quantitative real-time PCR was performed by using LightCycler® 480 Real-Time PCR System (Roche, Germany) and SYBR Green II PCR Master Mix (Takara, Dalian, China). The amplification programme was performed as described in our previous study [40 (link)]. Three biological replicates were carried out for each sample. Transcript levels were calculated using the 2–∆∆Ct method and normalized using the longan Actin gene (Dlo_028674) [5 (link)] or Arabidopsis Actin2 as an internal control. Genes that were up- or downregulated by at least twofold were considered differentially expressed.
