Nature Research Centre, Akademijos str. 2, 08412 Vilnius, Lithuania.
Yeasts produce numerous antimicrobial agents such as killer toxins, volatile organic compounds (VOCs), and other secondary metabolites, establishing themselves in developing natural and sustainable biocontrol strategies for agriculture and food preservation. This study addressed the biocontrol potential of yeasts, isolated from spontaneous fermentations of rosehips ( L.) and rowanberries ( L.

Article Synopsis
- Innovative strategies are needed to combat fungal pathogens for sustainable crop protection, with traditional fungicides facing resistance issues due to their single-target action.
- The study investigated the synergistic effects of chitosan (CS) and the fungicide azoxystrobin, finding a high synergy score that significantly improves antifungal efficacy.
- Additionally, combining CS and azoxystrobin with RNA interference techniques enhanced fungal control, highlighting a promising eco-friendly approach and the need for further research on its molecular mechanisms.
The Prevalence of Killer Yeasts in the Gardens of Fungus-Growing Ants and the Discovery of Novel Killer Toxin named Ksino.

Killer toxins are proteinaceous antifungal molecules produced by yeasts, with activity against a wide range of human and plant pathogenic fungi. Fungus gardens of attine ants in Brazil were surveyed to determine the presence of killer toxin-producing yeasts and to define their antifungal activities and ecological importance. Our results indicate that up to 46% of yeasts isolated from specific fungal gardens can be killer yeasts, with an overall prevalence of 17% across all strains tested.

Article Synopsis
- Dothistroma septosporum and Dothistroma pini are harmful pathogens that attack conifers, particularly pine trees, leading to severe damage such as needle loss and tree death.
- A study conducted on various Dothistroma isolates revealed the presence of viral dsRNA segments in some strains, indicating the potential for mycoviruses to help control these pathogens.
- Thirteen new potential viruses were identified, including a range of RNA virus types, with one being a narnavirus specifically associated with D. pini, marking the first virus discovered in this species.
Root-knot nematodes exploit the catalase-like effector to manipulate plant reactive oxygen species levels by directly degrading HO.

Plants produce reactive oxygen species (ROS) upon infection, which typically trigger defence mechanisms and impede pathogen proliferation. Root-knot nematodes (RKNs, Meloidogyne spp.) represent highly detrimental pathogens capable of parasitizing a broad spectrum of crops, resulting in substantial annual agricultural losses.
