Salt Stress-Induced Structural Changes Are Mitigated in Transgenic Tomato Plants Over-Expressing Superoxide Dismutase

Biology, 2020
Various abiotic stresses cause the appearance of reactive oxygen species (ROS) in plant cells, which seriously damage the cellular structures. The engineering of transgenic plants with higher production of ROS-scavenging enzyme in plant cells could ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Flood sediments as a source of replenishment of alluvial soils with plant nutrition elements

Аграрная наука Евро-Северо-Востока
Flood sedimentation in conditions of regular floodplain flooding is a key factor in the formation of alluvial soil.  The nature of the passage of hollow waters and their composition affect the quantitative and qualitative characteristics of flood ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Superharmonic proton motion in high-energy-density organic electrodes for aqueous zinc batteries

Nature Communications
The limited proton transfer kinetics within organic positive electrodes restricts the proton storage capacity and hinders achieving high energy density in aqueous zinc-organic batteries.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Understanding how loneliness relates to user behavior in an interactive virtual reality cafe

Frontiers in Virtual Reality
Loneliness is a growing concern among young adults. Though loneliness is distinct from social isolation, studies indicate that causes can stem from diminishment in the parameters of social contact that underlie isolation. In this work, we analyze how pre-

Accounting of infiltration waters and the level of recharge of the root layer by groundwater when calculating the irrigation regime on drained lands [PDF]

BIO Web of Conferences
The paper provides a justification for the need to take into account the inflow of infiltration waters into the soil profile and groundwater recharge when calculating the irrigation regime of agricultural crops. The studies were performed on sod-podzolic

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
