On the link between cell cycle and infection of the Alphaproteobacterium Brucella abortus
Michaël Deghelt, Jean-Jacques Letesson, Xavier De Bolle
This article comments on work published by Deghelt et al. (Nat Comm, 2014), which describe a cell cycle arrest and resume during the Brucella abortus trafficking in host cell, suggesting that like the model Alphaproteobacterium Caulobacter crescentus, these bacteria are able to block their cell cycle at the G1 phase when starvation is sensed.

Combinatorial stress responses: direct coupling of two major stress responses in Escherichia coli
Daniel R. Brown, Geraint Barton, Zhensheng Pan, Martin Buck and Sivaramesh Wigneshweraraj
This article comments on work published by Brown et al. (Nat Comm, 2014), which showed that the transcription of relA is activated by NtrC during nitrogen starvation, revealing that in E. coli and related bacteria, NtrC functions in combinatorial stress and serves to couple two major stress responses, the Ntr response and stringent response.

This work characterizes the involvement of MAPK signaling pathways in cell death induced by acetic acid in Saccharomyces cerevisiae.
Extracellular calcium triggers unique transcriptional programs and modulates staurosporine-induced cell death in Neurospora crassa
A. Pedro Gonçalves1,2, João Monteiro2, Chiara Lucchi2, David J. Kowbel3, J. Miguel Cordeiro1,4, Paulo Correia-de-Sá1,4, Daniel J. Rigden5, N. Louise Glass3, Arnaldo Videira1,2
The results presented here reveal that in Neurospora crassa, extracellular Ca2+ modulates cell death and the transcriptional alterations induced by staurosporine, and lead to the identification of two novel putative Ca2+-binding proteins, encoded by the NCU08524 and NCU06607 genes.
Multiple metabolic requirements for size homeostasis and initiation of division in Saccharomyces cerevisiae
Shivatheja Soma, Kailu Yang, Maria I. Morales and Michael Polymenis
This article reveals an unexpected diversity in the G1 cell cycle phenotypes of metabolic and biosynthetic Saccharomyces cerevisiae mutants, suggesting that growth requirements for cell division are multiple, distinct and imposed throughout the G1 phase of the cell cycle.
What’s the role of autophagy in trypanosomes?
Katherine Figarella1 and Néstor L. Uzcátegui1,2
This article comments on Proto et al. (Microbial Cell, 2014), who report first insights into the molecular mechanism of autophagy in African trypanosomes by generating reporter bloodstream form cell lines.
Tracking autophagy during proliferation and differentiation of Trypanosoma brucei
William R. Proto1, Nathaniel G. Jones1, Graham H. Coombs2, and Jeremy C. Mottram1
This article provides insights into the function of autophagy, a cellular degradation and recycling pathway, in the protozoan parasite Trypanosoma brucei.
Plasmodium spp. membrane glutathione S-transferases: detoxification units and drug targets
Andreas Martin Lisewski
This article comments on work published by Lisewski et al. (Cell, 2014), which reported the first examples of membrane-associated proteins in eicosanoid and glutathione metabolism members among Plasmodium spp.
Proline cis-trans isomerization is influenced by local lysine acetylation-deacetylation
Françoise S. Howe and Jane Mellor
This article comments on work published by Howe et al. (Mol Cell, 2014), which shows that local lysine acetylation and deacetylation modulate proline cis-trans isomerization in Saccharomyces cerevisiae.

The replication timing program in the hands of two HDACs
Kazumasa Yoshida1,2, Armelle Lengronne1 and Philippe Pasero1
This article comments on work published by Yoshida et al. (Mol Cell, 2014), which performed a systematic analysis of the role of histone deacetylases (HDACs) in the regulation of origin activity in budding yeast, finding that the epigenetic regulation of repetitive sequences is a key determinant of the DNA replication program.
