Premise of the study: PCR amplification of DNA extracted from plants is sometimes difficult due to the presence of inhibitory compounds. An effective method to overcome the inhibitory effect of compounds that contaminate DNA from difficult plant specimens is needed.
Methods and Results: The effectiveness of a PCR additive reagent containing trehalose, bovine serum albumin (BSA), and polysorbate‐20 (Tween‐20) (TBT‐PAR) was tested. PCR of DNA extracted from fresh, silica‐dried, and herbarium leaf material of species of Achariaceae, Asteraceae, Lacistemataceae, and Samydaceae that failed using standard techniques were successful with the addition of TBT‐PAR.
Conclusions: The addition of TBT‐PAR during routine …
