The effectiveness of biochar application to promote plant growth and suppress diseases is usually dependent on the dose biochar. Here, we evaluated effects supplied at 0%, 1%, 2%, 3% (w/w) tomato growth, Fusarium wilt disease severity, rhizosphere microbial community diversity. We found that applied 1% 2% promoted decreased severity disease. High-throughput amplicon sequencing indicated alpha d...

A new myosin motor-like chitin synthase gene, chsVb, has been identified in the vascular wilt fungus Fusarium oxysporum f. sp. lycopersici. Phylogenetic analysis of the deduced amino acid sequence of the chsVb chitin synthase 2 domain (CS2) revealed that ChsVb belongs to class VII chitin synthases. The ChsVb myosin motor-like domain (MMD) is shorter than the MMD of class V chitin synthases and ...

Crude extracts from a medicinal Tunisian plant, Pergularia tomentosa L., were the investigated natural material. Butanolic extract of roots analyzed with IR spectra revealed the presence of hydroxyl, alcoholic, and carboxylic groups and sugars units. Analysis of some secondary metabolites, total phenolic, flavonoids, flavonols, and procyanidins, was performed using different solvents following ...
