FP gene copy numbers in the A. digitifera genome were estimated by quantitative PCR (qPCR) using 11 A. digitifera specimens. FP gene copy number estimation was performed using previously described methods (Takahashi-Kariyazono et al. 2016 (link)) with minor modifications. Briefly, two new reverse primers (MLWE_qPCR_R1-3 for M/LWE and MiA_CP_e3_R1-3 for CP) were used for qPCR. Primer sequences are shown in supplementary table S2, Supplementary Material online. qPCR was performed using the Thermal Cycler Dice TP800 (Takara). Genomic DNAs of 11 samples (S1601–8, S1610–12) were used as templates.
