Global‐Scale Patterns of Host Transitions Suggest Contrasting Levels of Specialization Within Rhizoctonia solani

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We combined a global rDNA‐ITS dataset with TEF‐1α sequences and newly sequenced isolates to examine phylogenetic signal, host associations, and population structure in the soil‐borne pathogen Rhizoctonia solani. Most anastomosis groups formed well‐supported clades, and host‐associated patterns corresponded more strongly with genetic structure than ...

Organic‐Microbial Strategies for Iron and Zinc Biofortification in Orange‐Fleshed Sweet Potato [Ipomoea batatas (L.) Lam.]

open access: yesFood Science &Nutrition, Volume 14, Issue 9, September 2026.
Orange‐fleshed sweet potato (OFSP) is valued for its provitamin A content but remains poor in iron (Fe) and zinc (Zn). In a two‐season field trial in Senegal, combining locally available organic waste products (poultry litter, PL; sewage sludge, SS) with microbial inocula (beneficial microorganisms, BM; mycorrhizal fungi, MF) significantly improved ...
