FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Increase in root density induced by coronatine improves maize drought resistance in North China
Crop Journal, 2023 Drought stress caused by insufficient irrigation or precipitation impairs agricultural production worldwide. In this study, a two-year field experiment was conducted to investigate the effect of coronatine (COR), a functional analog of jasmonic acid (JA),

Intercomparison of snow density measurements: bias, precision, and vertical resolution [PDF]
, 2016 Density is a fundamental property of porous media such as snow. A wide range of snow properties and physical processes are linked to density, but few studies have addressed the uncertainty in snow density measurements.

Agronomy, 2021 (Aims) To clarify the mechanisms though which dense planting could alleviate the negative effect of the reducing N rate on yield, (Methods) an experiment with four nitrogen levels—0 (N0), 120 (N1), 180 (N2) and 240 (N3) kg N ha−1—and three plant ...

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Stomatal density correlates with root area.
, 2016 (A) Histochemical staining of seedlings expressing pEPF1::GUS (top) indicates EPF1 expression in guards cells but not in roots, and pEPF2::GUS (bottom) indicates EPF2 expression in early stomatal lineage cells and not in roots.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Different root growth patterns in tomato seedlings grown hydroponically under an electric field [PDF]
, 2013 Electric fields can determine changes at morphological and physiological levels in plants. In this study, seedlings of Solanum lycopersicum L., grown hydroponically in a floating system, were exposed to a DC 12.0 V m–1 electric field (EF).
