Regulatory features determine the evolutionary fate of laterally acquired genes in plants Abstract. Lateral gene transfer (LGT) is widespread in eukaryotes, including in animals and plants where it can fuel adaptive evolution and innovation. How

Collins et al. combined expression, methylation, and genomic data to investigate long-term persistence of laterally acquired genes in the grass Alloteropsis, showing that those capable of regulating their own expression are more likely to persist.

'Viral infections thus may appear to add fuel to the multifactorial fire of neurodegeneration, whether by direct damage or via the immune sys. To us, this insight may also give hope for future preventive strategies, as targeting infections could reduce the risk of getting neurodegenerative diseases'

Novel killer yeasts and toxins from the gardens of fungus-growing ants | Applied and Environmental Microbiology Attine ants perform essential ecosystem services through the harvesting of substrates for fungiculture. The cultured fungi are a food source for attine ants. Characterizing antifungal toxin-producing yeasts (killer yeasts) is vital to understanding how they might protect gardens from invasion by unwanted fungal species. This study also describes a new toxin named Ksino from the yeast Candida sinolaborantium, a member of a new group of toxins found across many different species of fungi. This work supports the role of killer yeasts in the ecology of fungicultures and competition between fungi. The observed high prevalence of killer yeasts in fungal gardens also enables the discovery of novel antifungal molecules with the potential to be applied against disease-causing fungi.
