“…Besides that, airborne pollen is also a critical component of bioaerosol which causes pneumonia, chronic obstructive pulmonary, cardiovascular, and allergic respiratory diseases. 12 The morbidity rate of pollen allergy is estimated at 40% in Europe, 13 while the value rose to 47.8% in China. 14 These active airborne particles could be captured by HVAC filters.…”

Air conditioning is a crucial participant in indoor air circulation and harmful microorganism transmission. To elucidate microbial contamination in air conditioning systems, bacteria, fungi, and pollens in residential air conditioning (AC) filters in Shanghai were revealed. The concentrations of fungal ITS (1,972,037 ± 5,025,505 copies/cm 2 ) in most filter samples were considerably higher than the 16S rRNA gene (21,587 ± 21,461 copies/cm 2 ). The multitudinous bacteria determined a higher richness, whereas the trend was not in line with fungi, owing to Aspergillus flourishing, with an average of 43.75%. Numerous bacteria that may often be prevalent in human skin, mucous membranes, and intestines, such as Enhydrobacter, Micrococcus, Staphylococcus, Streptococcus, and Haemophilus, were also discovered in AC filters. The pollens were affiliated with Streptophyta at phylum, and Humulus was the most abundant genus (mean value 67.84%), raising the possibility of allergic responses. This study provides a better understanding of the microbial characteristics of AC filters, enables more rational approaches for microbe contaminant control, and ultimately improves human health in megacities.

“…pyramidalis , which prevents the species from generating catkins in summer. Some studies have shown that catkins can carry up to 6.33 × 10 4 bacterial and 7.46 × 10 5 fungal cells (Xu & Yao, 2020 ) and cause allergic reactions and respiratory disease (Buters et al, 2008 ; Katz et al, 2020 ; Kim, Kwak, et al, 2020 ). In addition, whirling catkins can reduce visibility, affecting the accuracy of some high‐precision instruments (Tang et al, 2014 ).…”

For many clonally propagated species, the accumulation of somatic mutations is the principal driver of declines in yield and quality. However, somatic mutations may also promote genetic diversification. Thus, elucidating somatic mutation rates and patterns is important to understand the genetic basis undergirding the emergence of commercially valuable traits and developmental processes. In this study, we studied the effect of short‐time clonal domestication of Populus alba var. pyramidalis, a species that has been propagated by cutting for the last 67 years. We found that: (1) the somatic mutation rate for P. alba var. pyramidalis is 9.24 × 10−9, which is higher than rates observed in related species; (2) there were more mutations near heterozygous regions, and a larger proportion of CpG and CHG sites were associated with somatic mutations, which may be related to the blocking of DNA repair by methylation; and (3) deleterious mutations were not shared by multiple individuals, and all occurred in heterozygous states, demonstrating the strong selective pressures that act against deleterious mutations. Taken together, the results of our study provide a global view of somatic mutation that will aid efforts to understand the genetic basis of commercially valuable traits and to improve clonally breeding species.
