Characterization of a novel endornavirus isolated from the phytopathogenic fungus Rhizoctonia solani.

Rhizoctonia solani endornavirus 8 (RsEV8) was isolated from strain XY175 of Rhizoctonia solani AG-1 IA. The full-length genome of RsEV8 is 16,147 nucleotides (nt) in length and contains a single open reading frame that encodes a large polyprotein of 5227 amino acids. The polyprotein contains four conserved domains: viral methyltransferase, putative DEAH box helicase, viral helicase, and RNA-dependent RNA polymerase (RdRp).

The effects of short-term, long-term, and reapplication of biochar on the remediation of heavy metal-contaminated soil.

Biochar, a cost-effective amendment, has been reported to play pivotal roles in improving soil fertility and immobilizing soil pollutants due to its well-developed porous structure and tunable functionality. However, the properties of biochar and soils can vary inconsistently after field application. This may affect the remediation of biochar on heavy metal (HM)-contaminated soil being altered.

Study on the physicochemical properties changes of field aging biochar and its effects on the immobilization mechanism for Cd and Pb.

It has been widely reported that biochar can be used as a cost-effective amendment to immobilize of heavy metal contaminants in soil. While less research has been conducted on effect of biochar long-term field aging on its properties and the adsorption capability. In this study, the characteristics of aged biochar were investigated by comprehensive characterization to elucidate its mechanism transformation for heavy metal immobilization.
