In this review, we propose unified criteria for the definition of accidental, regulated, and programmed forms of cell death in yeast based on a series of morphological and biochemical criteria. Specifically, we provide consensus guidelines on the differential definition of terms including apoptosis, regulated necrosis, and autophagic cell death, as we refer to additional cell death routines that are relevant for the biology of yeast.
Burkholderia gladioli strain NGJ1 deploys a prophage tail-like protein for mycophagy
Rahul Kumar1, Sunil Kumar Yadav1, Durga Madhab Swain1 and Gopaljee Jha1
In this article, the authors comment on the study "A prophage tail-like protein is deployed by Burkholderia bacteria to feed on fungi" by Swain et al. (Nature Communications, 2017), discussing that a prophage tail-like protein (Bg_9562) is essential for mycophagy. The protein may help the bacteria to survive in certain ecological niches and, considering its broad-spectrum antifungal activity, may be potentially useful in biotechnological applications to control fungal diseases.
Ras signalling in pathogenic yeasts
Daniel R. Pentland1, Elliot Piper-Brown1, Fritz A. Mühlschlegel1,2 and Campbell W. Gourlay1
In this article Pentland et al. review the roles of Ras protein function and signalling in the major human yeast pathogens Candida albicans and Cryptococcus neoformans and discuss the potential for targeting Ras as a novel approach to anti-fungal therapy.
A novel basolateral type IV secretion model for the CagA oncoprotein of Helicobacter pylori
