Figure 2: Workflow including potential limitations (inserted box) in each step for eDNA analysis in Plant-animal interactions (PAI) detection (cPCR = conventional PCR, qPCR = quantitative PCR, ddPCR = droplet digital PCR, CRISPR-cas = Clustered Regularly Interspaced Short Palindromic Repeats- CRISPR-associated protein, NGS= next generation sequencing).
