*4.9. PCR Detection of Cassava Plants*

The transient expressed cassava plants were detected by PCR using genomic DNA and cDNA, with a PCR program of (1) 94 °C for 3 min; (2) 29 cycles of 94 °C for 30 s, 55 °C for 30 s, and 72 °C for 2 min; and (3) 72 °C for 10 min and 16 °C for storage. The primers are listed in Supplementary Table S4.
