Application of ethylene diurea (EDU) in assessing the response of a tropical soybean cultivar to ambient O3: Nitrogen metabolism, antioxidants, reproductive development and yield

Moderate drought did not affect the effectiveness of ethylenediurea (EDU) in protecting Populus cathayana from ambient ozone

“…Higher chlorophyll content in EDU compared with non-EDU-treated plants suggests that EDU delayed foliar senescence by reducing oxidative stress. Similar results were also found in soybean and snap bean (Rai et al, 2015;Yuan et al, 2015). By maintaining higher carotenoids concentration, chlorophyll damage due to O 3 is also avoided because carotenoids provide photoprotection and are antioxidant molecules (Demmig-Adams and Adams, 1996).…”

Assessing the effects of ambient ozone in China on snap bean genotypes by using ethylenediurea (EDU)

“…Phenolic metabolites are suggested to play a protective role against oxidative stress as antioxidants (Kangasj€ arvi et al, 1994). In an EDU-treated soybean genotype, total phenolics content decreased (Rai et al, 2015); it was interpreted that a relative abundance of carbon in EDU-treated plants influenced the rate at which the substrate, i.e. phenylalanine is diverted to protein synthesis, as protein and phenolic allocation are inversely correlated (Jones and Hartley, 1999).…”

Effects of Elevated Tropospheric Ozone Concentration on the Bacterial Community in the Phyllosphere and Rhizoplane of Rice

“…The background concentration of tropospheric ozone was around 20 ppb in the beginning of the 20 th century [ 15 ], but the current background concentration has reached 60 ppb in many parts of the world, periodically reaching 80 ppb as a monthly average in some parts of Asia [ 15 , 16 ]. These concentrations are far beyond the critical level for plants [ 17 ] and damage cultivated crops and natural vegetation [ 18 , 19 ]. This trend will exacerbate in the future, especially in Asian countries, due to continuing industrialization and rising precursor gas emissions [ 20 ].…”
