Phosphate (Pi) availability guides root growth. Naumann et al. show Arabidopsis LPR1 typifies a novel ferroxidase that links antagonistic Fe-Pi interactions to local Pi sensing by root tips via Fe redox cycling. Streptophyte ancestors gained LPR1-type ferroxidase from soil bacteria by horizontal gene transfer, which benefited plant terrestrializati...

Toret et al. delve into the biology of the Fonticula alba , a unique cellular slime mold that is sister to fungi. They discover a cryptic, emergent, and invasive multicellular organization with parallels to invasive hyphae. This study sheds light on the multicellular organizations that occur within the fungi-animal divergence.

Lin et al. explore how evolutionary divergence constrains the potential of de-extinction, using the Christmas Island rat as a model. Although 95% of its genome is recovered when re-sequenced at high depth, regions that remain unmapped to the reference likely have significant consequences for any attempt at de-extinction using genome editing.

Davis et al. use live imaging and computational methods to quantitatively analyze developmental growth in the Drosophila adult abdominal epidermis. Abdominal growth is initiated by the degradation of the basement membrane on which the epidermal progenitors are attached and terminated by a rapid exit from the cell cycle rather than a gradual slowdow...

Barreto et al. uncover a retrograde signaling mechanism that links inner mitochondrial membrane protein UCP1 to cytoplasmic oxygen sensing. UCP1 activity is transduced via inhibition of the PCO N-degron pathway to influence gene expression. This mechanism integrates mitochondrial and nuclear functions during development and in response to stress.

Most work on the perception of three-dimensional shapes has focused on grayscale images of achromatic surfaces. Marlow et al. show that color plays a functional role in shape perception of translucent surfaces. The physics of subsurface scattering causes saturation to vary in similar ways to the shading patterns of opaque surfaces.

Lau et al. identify that the self-templating yeast mnemon Whi3 is retained in the mother cell during cell division after the memorization of a deceptive mating attempt through an association with compartmentalized endoplasmic reticulum membranes. This confinement is required to prevent the appearance of a mitotically stable prion-like behavior of W...

By using functional imaging and pharmacological manipulation, Khalighinejad et al. show that, although basal forebrain and cholinergic system modulate decisions about when to act by mediating the influence of specific aspects of immediate context on behavior, dorsal raphe nucleus and serotonergic system mediate the influence of the wider environmen...

Van Elzelingen et al. simultaneously track striatal dopamine signaling and development of habitual behavior. In the dorsomedial striatum, previously associated with non-habitual behavior, dopamine release increases during action initiation in habitual rats and decreases during action completion, whereas non-habitual rats show opposite effects.

How environmental fungi evolved virulence mechanisms to opportunistically infect humans is unclear. Itabangi et al. identify a tri-kingdom interaction, whereby a bacterial endosymbiont living within a fungus causes the generation of a secreted factor that blocks the predatory activity of amoebas and drives virulence in animal models.
