“…Concerning the first, the atmospheric particulate would play the role of transport vector ( Chen et al, 2010 ; Despres et al, 2012 ; Cao et al, 2014 ; Lei et al, 2018 ; Magazzino et al, 2020 ). Regarding indirect effects, prolonged inhalation of fine and ultrafine particulates would induce oxidative stress and cellular inflammation of the lungs, which would assist the adverse effects of respiratory viruses (COVID-19) on patients ( Bengalli et al, 2019 ; Esquivel-Fariña et al, 2019 ; Li et al, 2020 ; Putrino et al, 2020 ). These results have led numerous international and academic research centers to more precisely analyze the role of high concentrations of PM 10 and PM 2.5 in the spread, morbidity, and mortality attributable to the pandemic COVID-19 virus ( Dominici et al, 2020 ; Magazzino et al, 2020a , b , c , d ; Mahase, 2020 ; Remuzzi et al, 2020 ).…”

The aim of this paper is to assess the relationship between COVID-19-related deaths, economic growth, PM 10 , PM 2.5, and NO 2 concentrations in New York state using city-level daily data through two Machine Learning experiments. PM 2.5 and NO 2 are the most significant pollutant agents responsible for facilitating COVID-19 attributed death rates. Besides, we found only six out of many tested causal inferences to be significant and true within the AUPRC analysis. In line with the causal findings, a unidirectional causal effect is found from PM 2.5 to Deaths, NO 2 to Deaths, and economic growth to both PM 2.5 and NO 2 . Corroborating the first experiment, the causal results confirmed the capability of polluting variables (PM 2.5 to Deaths, NO 2 to Deaths) to accelerate COVID-19 deaths. In contrast, we found evidence that unsustainable economic growth predicts the dynamics of air pollutants. This shows how unsustainable economic growth could increase environmental pollution by escalating emissions of pollutant agents (PM 2.5 and NO 2 ) in New York state.

“…The moloney murine leukemia virus reverse transcriptase (M−MLV RT) is often used in many studies, at a concentration of 200 U (Promega; São Paulo; Brazil) per reaction. 2 In the present study, the M−MLV (RT) enzyme was chosen due to its cost-effectiveness. However, the reactions were performed with reduced concentrations of 100 U and 50 U.…”

“…Wheat stripe mosaic virus (WhSMV) is a plant-pathogenic virus consisting of two segments of polyadenylated single-strand ssRNA (RNA1 and RNA2), found in Southern Brazil, 1 Paraguay, 2 and South Africa, 3 and causes considerable yield loss in infected wheat and other cereal crops. The primary mode of transmission is through the plasmodiophorid Polymyxa graminis , an obligate plant parasitic soil inhabitant that infects the roots of wheat and other cereals.…”

“…More recently, it was demonstrated that SBWMD in Brazil is in fact caused by a different virus, classified as a member of the family Benyviridae and named as wheat stripe mosaic virus (WhSMV) (Valente et al., 2019). Following its description in Brazil, WhSMV was then found in Paraguay (Esquivel‐Fariña et al., 2019) and in South Africa (Terefe et al., 2021).…”

Wheat stripe mosaic virus (WhSMV) is the causal agent of soilborne wheat mosaic disease (SBWMD) in Brazil, which is a serious threat to wheat production in the southern part of the country. WhSMV also occurs in Paraguay and South Africa. The virus is soilborne, transmitted by Polymyxa graminis, and management strategies are mainly based on genetic resistance. Variation in the reaction (type and severity of symptoms) of cultivars has been reported depending on the region and/or year of cultivation, leading wheat breeding programmes to test their materials in several locations, which increases costs and is time‐consuming. One hypothesis is that this variation in symptoms is a result of the genetic variability of WhSMV. We assessed the genetic variability and population structure of WhSMV infecting wheat in Brazil and South Africa. In field experiments conducted in different locations in southern Brazil, a consistent reproducibility of symptoms was observed in a set of cultivars, and molecular analysis showed a low degree of genetic variability of the Brazilian viral population. The hypothesis that the variation in SBWMD symptoms in Brazil is due to genetic variability of the virus was thus rejected. Comparison of the Brazilian and South African WhSMV isolates indicated that they comprise distinct subpopulations and that the Brazilian subpopulation is more variable than the South African subpopulation. The lower genetic variability of the South African subpopulation suggests genetic stability or a recent emergence of WhSMV in that region.
