Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

open access: yesEcological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Arsenate immobilization associated with microbial oxidation of ferrous ion in complex acid sulfate water

open access: yes, 2012
Chemical, XRD, SEM, RS, FTIR and XPS techniques were used to investigate arsenate immobilization associated with microbial Fe2+ oxidation in a complex acid sulfate water system consisting of a modified 9 K solution (pH 2.0) plus As, Cu, Cd, Pb, Zn and Mn.

The IKU2/RLK7–MAPK–MINI3 signaling module controls endosperm cellularization timing to determine seed size in Arabidopsis

open access: yesJournal of Integrative Plant Biology, EarlyView.
The phosphorylation status of the WRKY transcription factor WRKY10/MINI3, controls the timing of endosperm cellularization in Arabiopsis, thus regulating final seed size, offering a molecular understanding that could inform future agricultural breeding strategies. ABSTRACT Seed size is a critical factor in determining crop yield.

Adenine nucleotide translocator and ATP synthase cooperate in mediating the mitochondrial permeability transition

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Both ATP synthase and adenine nucleotide translocator (ANT) play key roles in mediating the permeability transition. The contribution of ANT becomes evident in the presence of atractylate (ATR) at pH 6.5, a condition that prevents ATP synthase channel activity. At pH 7.4, this effect is minimal, suggesting a critical role for ATP
