Cadmium (Cd) is an extremely toxic heavy metal that can originate from industrial activities and accumulate in agricultural soils. This study investigates the potential of biologically synthesized silicon oxide nanoparticles (Bio-SiNPs) in alleviating Cd toxicity in bayberry plants. Bio-SiNPs were synthesized using the bacterial strain Chryseobacterium sp.

Rice blast, an extremely destructive disease caused by the filamentous fungal pathogen Magnaporthe oryzae, poses a global threat to the production of rice (Oryza sativa L.). The emerging trend of reducing dependence on chemical fungicides for crop protection has increased interest in exploring bioformulated nanomaterials as a sustainable alternative antimicrobial strategy for effectively managing plant diseases.

Article Synopsis
  • - The study focuses on using moringa chitosan nanoparticles (M-CsNPs) as a sustainable alternative to traditional pesticides for combating rice blast disease (RBD) caused by the fungus Magnaporthe oryzae, which poses a threat to food security.
  • - M-CsNPs demonstrated significant effectiveness in suppressing pathogen growth and reducing RBD by 77.7% in greenhouse tests, while also enhancing plant health and antioxidant activity.
  • - The research revealed that M-CsNPs not only lower the abundance of the pathogen in rice plants but also improve the microbial diversity in the plant's environment, promoting beneficial bacteria that enhance growth and resilience against diseases.

The pathogenic fungus Pestalotiopsis versicolor is a major etiological agent of fungal twig blight disease affecting bayberry trees. However, the lack of complete genome sequence information for this crucial pathogenic fungus hinders the molecular and genetic investigation of its pathogenic mechanism. To address this knowledge gap, we have generated the complete genome sequence of P.

Decline disease is a new disease that has recently caused severe damage in bayberry industry. The effect of biochar on decline disease was determined by investigating the changes in the vegetative growth and fruit quality of bayberry trees as well as soil physical and chemical properties, microbial community structure, and metabolites. Results indicated that the application of biochar could improve the vigor and fruit quality of diseased trees, and rhizosphere soil microbial diversity at the levels of phyla, orders, and genera.
