主　　题：Plant flowering Flying fluffy catkins Bio-agents Transmission Air pollution 

摘      要：Growing air pollution,known asApril snow,by fluffy catkins from plant flowering was frequently observed during the Spring time in *** efforts mainly focus on controlling catkin release,while their public health and environmental impacts are ***,using culturing,microscopic and sequence methods we found that the flying catkins carry a significant amount of bio-agents(bacteria,fungal,viruses,and pollens),e.g.,up to 6.33×10^4 bacterial and 7.46×10^5 fungal cells per *** pollens from plants were also found riding on the flying *** collected fluffy catkins,bacterial Paracoccus,Massilia,fungal Ophiocordyceps,Arthrocladiella,pollen Robina,Pickeringia,Pinus,and viral family Genomoviridae,to name a few,were found to be *** infection and allergic potentials,the detected microbial structures on the fluffy catkins were different from those of local air,varying from one location to *** not just white pollution,flying plant fluffy catkins were discovered here also acting as a cloud of biological agents,and further actions need to be taken urgently to understand and limit their environmental and ecological consequences.
