What to know about Pollen movement tracked from ground to sky with new modeling method

Researchers from Virginia Tech have developed a new methodology for tracking and forecasting the atmospheric dispersal of pollen using genetically engineered fluorescent switchgrass, drones, and ground-based sampling. The study aims to improve the management of gene flow between plants and enhance the prediction of airborne allergens.

What happened

Pollen movement tracked from ground to sky with new modeling method Gaby Clark Scientific Editor Robert Egan Senior Editor Plant biologists and engineers have extended their studies to the skies to track airborne pollen once it leaves a crop.

Why it matters

In a new study, published in Environmental Monitoring and Assessment, researchers established an accurate methodology for tracking, measuring and forecasting pollen dispersal of genetically engineered switchgrass at both ground and atmospheric levels.

Common ground

"This is the first study to bring all these elements together in one experiment," said first author Manu Nimmala Ph.D.
