During their lifespans, plants release through their stems and leaves a wide range of biological particles, including fungal spores, pollen, bacteria, viruses, algae, and cell debris. When reaching the atmosphere, these particles can act as the nuclei for ice crystals or cloud droplets, thus having a significant environmental and climatic impact.  Although scientists have long been familiar with this process, little has been known about how the composition of this microbiome changes throughout a plant’s life cycle. Now, a team of researchers led by the Pacific Northwest...
