“…In nematodes, there were three metabolites, M1, M2 and M3 were determined, M1 appeared first, and then M2 and M3 formed almost simultaneously. The propyl group of IPP was de-esterified and hydrolyzed to form M1, which was accordance with the previous study (Cai et al 2015a(Cai et al ,2015bChen et al 2017). M1 was determined during the process of IPP biodegradation.…”

“…The toxicity differences between IPP and M1 at relatively high concentrations also occurred with the aid of head thrash, body bend, locomotion and lifespan. M1 is one of the intermediates of IPP biodegradation in environment, and also determined in soil after IPP application (Cai et al 2015a(Cai et al , 2015b(Cai et al , 2016a(Cai et al , 2016b(Cai et al , 2016cChen et al 2017;Fu et al 2013). The toxicity of toxicants in C. elegans is similar to the toxic results in mammals, the results in this study imply the possible potential more severe toxicity of IPP than M1 in mammals.…”

“…It has higher insecticidal activity (40-50 times) compared to imidacloprid-resistance pests, and also has low toxicity to human. In China IPP was used for pesticide control and sprayed for almost 3.3 million hectares (Cai et al 2016a;Chen et al 2017).…”

Caenorhabditis elegans, a kind of model organism, was used to investigate biodegradation pathway of IPP and M1 in nematodes, in vivo toxicity from IPP and M1 and the possible underlying molecular mechanism. The results showed that both IPP and M1 could decrease lifespan, locomotion behavior, reproductive ability and AChE activity. During IPP biodegradation process, three intermediates (M1-M3) were monitored and identified. Based on the identified metabolites and their biodegradation courses, a possible biodegradation pathway was proposed. IPP was probably transformed to different three metabolites in nematodes through oxidation and elimination of methyl and propyl etc. Under the same concentration, IPP had more severe toxicity than M1 on nematodes. IPP and M1 might reduce lifespan and decrease reproductive ability through influencing insulin/IGF signaling pathway and TOR signaling pathway. They could decrease expression levels of daf-16, sgk-1, aak-2, daf-15 and rict-1 genes, which involved in IGF and TOR signaling pathway.

“…and Chryseobacterium spp. have the ability to decompose xenobiotics (e.g., pesticides and carbazole) [45,46]; therefore, enrichment of these genera in the CP plot may be due to the use of agrochemicals [47]. Similarly, OTUs within the genus Comamonas have been frequently associated with degradation of complex compounds [13], and were strongly associated with CP.…”

Natural farming (NF), an environmentally friendly agricultural practice similar to organic farming, was developed in Japan. Unlike conventional farming, little is known about the influence of NF on soil microbial communities, especially the surface soil. We therefore compared the effect of seven years’ conventional practice (CP), conventional practice without chemicals (CF), and NF on soil properties and microbial community structure at two soil depths (0–10, 10–20 cm) in an experimental cabbage field. Both soil depth and agricultural practice significantly influenced edaphic measures and microbial community structure. NF improved bulk density, pH, electrical conductivity, urease activity, and nitrate reductase activity in topsoil; similar trends were observed in deeper soil. Pyrosequencing demonstrated that the use of pesticides in conventional farming (CP) led to lower microbial abundance and diversity in topsoil than CF. Similarly, NF increased microbial abundance compared to CP. However, distinct taxa were present in the topsoil, but not deeper soil, in each treatment. CP-enriched microbial genera may be related to plant pathogens (e.g., Erwinia and Brenneria) and xenobiotic degraders (e.g., Sphingobacterium and Comamonas). The microbial community structure of NF was distinct to CP/CF, with enrichment of Pedomicrobium and Solirubrobacter, which may prefer stable soil conditions. Network analysis of dominant genera confirmed the more stable, complex microbial network structure of the 0–10 cm than 10–20 cm layer. Flavisolibacter/Candidatus Solibacter and Candidatus Nitrososphaera/Leuconostoc are potentially fundamental taxa in the 0–10 cm and 10–20 cm layer networks, respectively. Overall, we show that NF positively affects soil quality and microbial community composition within sustainable farming systems.
