Bud-to-Bud Communication via Connective Auxin Transport

The growing shoot tips of a plant can communicate and influence each other’s growth. This study by Tom Bennett, Ottoline Leyser and co-workers reveals that this communication is mediated by a multimodal auxin transport network in the stem, with complex dynamics.

CdpR, Quorum-Sensing and Virulence

Jingru Zhao, Xiang Yu, Haihua Liang and co-authors find that the novel transcriptional regulator CdpR suppresses the expression of virulence factors and pathogenicity in Pseudomonas aeruginosa and is degraded by the ClpAS-P protease system.

Mapping Disease Space to Track Resilience

This study by Brenda Torres, Jose Oliveira, David Schneider and colleagues reveals that infections cause sick hosts to loop through disease space on their return back to health; resilient individuals take tiny loops through this space, minimizing the impact of the infection.

Defining Identity of Sensory Neurons & Circuits

The fruitless (fru) gene regulates sexual behavior in flies, but what regulates fru? This study by Catherine Hueston, Douglas Olsen, Pelin Cayirlioglu Volkan and co-authors shows that the chromatin modulator Alhambra restricts fru expression to specific neurons in the developing Drosophila olfactory system.

Farewell to Policing Plant Imports

This Perspective by Dani Zamir asks us to bid farewell to the failed strategy of policing plant imports and embark on genomics-assisted, biodiversity-based breeding to improve plant resilience to changing environments and to the pests of the future.

How Many Parameters Describe Disease Tolerance?

Experiments by Alexander Louie, Kyung Han Song, David Schneider and co-workers using fruit flies infected with Listeria monocytogenes show that changes in the shape of a disease tolerance curve can reveal the source of pathology for an infectious system.

Skull Measurements: Racial Bias or Liberal Bias?

Stephen Jay Gould once accused 19th century scientist Samuel Morton of racial bias in his measurement of crania. A 2011 PLOS Biology article by Jason Lewis and co-authors in turn accused Gould of liberal bias. This new Formal Comment by Michael Weisberg and Diane Paul defends Gould’s position.

What Governs ALS Protein Aggregation?

TDP-43 aggregation is implicated in amyotrophic lateral sclerosis. In response to a recent study, this Formal Comment argues for a alternative explanation of TDP-43's pH-dependent solubility.
