A plant Bcl-2-associated athanogene is proteolytically activated to confer fungal resistance
April 16, 2016
This article comments on work published by Li et al. (Plant Cell, 2016), which focuses on the role of Bcl-2-associated athanogene 6 (BAG6) in plant innate immunity, showing that BAG6 plays a key role in basal plant defense against fungal pathogens.
The molecular and cellular action properties of artemisinins: what has yeast told us?
April 14, 2016
Artemisinin (ART) or Qinghaosu is a natural compound possessing superior anti-malarial activity. Although intensive studies have been done in the medicinal chemistry field to understand the structure-effect relationship, the biological actions of artemisinin are poorly understood and controversial. This review summarizes what we have learned from yeast about the basic biological properties of ARTs, as well as some key unanswered questions.
Formaldehyde fixation is detrimental to actin cables in glucose-depleted S. cerevisiae cells
April 13, 2016
Actin filaments form cortical patches and emanating cables in fermenting cells of Saccharomyces cerevisiae. We assume that stability of actin cables reflects the metabolic status of the cell. Based on comparison of live and formaldehyde-fixed cells, our data suggest that formaldehyde affects respiration before fixation and this uneven signaling results in destabilization of actin cables in glucose-deprived cells.
Chemical proteomics approach reveals the direct targets and the heme-dependent activation mechanism of artemisinin in Plasmodium falciparum using an activity-based artemisinin probe
April 5, 2016
This article comments on work published by Wang et al. (Nat Commun, 2014), which provides insights into the mode-of-action of artemisinin and its specificity against malaria parasites.
Translational repression in malaria sporozoites
April 5, 2016
This article comments on work published by Zhang et al. (PLoS Pathog, 2016), which summarizea recent advances in the translational repression of gene expression in the malaria sporozoite.
What’s old is new again: yeast mutant screens in the era of pooled segregant analysis by genome sequencing
April 4, 2016
This article comments on work published by Den Abt et al. (Microbial Cell, 2016), which identified genes involved in ethyl acetate formation in a yeast mutant screen based on a new approach combining repeated rounds of chemical mutagenesis and pooled segregant analysis by whole genome sequencing.
Chromatin binding and silencing: Two roles of the same protein Lem2
April 4, 2016
This article comments on work published by Barrales et al. (Genes Dev, 2016), which identifies the nuclear envelope protein Lem2, a homolog of metazoan lamin-associated proteins (LAPs), as a relevant factor for heterochromatin silencing and perinuclear localization in the fission yeast Schizosaccharomyces pombe.
When and where? Pathogenic Escherichia coli differentially sense host D-serine using a universal transporter system to monitor their environment
March 31, 2016
This article comments on work published by Connolly et al. (PLoS Pathog, 2016), which describes the discovery of a functional and previously uncharacterized D-serine uptake system in E. coli.
Non-genetic impact factors on chronological lifespan and stress resistance of baker’s yeast
April 13, 2016
This article comments on work published by Bisschops et al. (Microbial Cell, 2015), which illustrates how important the choice of the experimental setup is and how culture conditions influcence cellular aging and survival in biotechnological processes.
