How to store pollen for analysis

Pollen sampling by citizen scientists (CS) is underway in several countries. How to store the pollen until molecular analysis? How to transport the pollen between the CS and the lab? These are important questions addressed by INSIGNIA. Storage and transportation will influence DNA quality and quantity, both important features for reliable botanical identification via metabarcoding. INSIGNIA compared storage in ethanol with freezing. It turns out that storage in ethanol assures good DNA quality quantity, which makes storage and transportation easier.
