Article Synopsis
  • Silica (SiO) particles are valued in industries for their durability and stability, and this study focuses on creating specialized porous microcapsules (MCs) from them.
  • The researchers developed hydrophobic and hydrophilic SiO MCs by layering SiO particles onto polystyrene microspheres and then removing the core, exploring how variations in size and quantity affect their properties.
  • The resulting microcapsules showed practical applications, successfully integrating into polymer films for mold prevention and effectively killing a harmful virus when filled with hydrogen peroxide.

During our search for aphid-pathogenic viruses, a comovirus was isolated from wild asymptomatic (white mustard) plants harboring a dense population of aphids. The transmission-electron-microscopy visualization of purified virions revealed icosahedral particles. The virus was mechanically transmitted to plants belonging to , , and families, showing unique ringspot symptoms only on var.

Article Synopsis
  • Carrots from the Western Negev in Israel exhibited various disease symptoms in 2019, prompting an investigation into the role of plant viruses despite the absence of known carrot yellows pathogens.
  • High throughput sequencing revealed a new waikavirus with about 70% sequence identity to known waikavirus members, and its presence was confirmed through various molecular techniques.
  • Phylogenetic analysis indicated that this newly identified waikavirus is closely related to the persimmon waikavirus and actinidia yellowing virus 1, and it can be transmitted to other plants via the psyllid Bactericera trigonica.

Combined infection of the host plant with pathogens involving different parasitic lifestyles may result in synergistic effects that intensify disease symptoms. Understanding the molecular dynamics during concurrent infection provides essential insight into the host response. The transcriptomic pattern of cucumber plants infected with a necrotrophic pathogen, , and a biotrophic pathogen, Cucumber green mottle mosaic virus (CGMMV) was studied at different time points, under regimes of single and co-infection.
