Subgenome dominance shapes novel gene evolution in the decaploid pitcher plant Nepenthes gracilis

This study shows how subgenome dominance in the decaploid pitcher plant Nepenthes gracilis contributes to novel gene evolution linked to its carnivorous traits and dioecy.

ALMT-independent guard cell R-type anion currents

The paper identifies that R-type anion currents in Arabidopsis guard cells are not solely mediated by ALMT12/QUAC1, as other channel species contribute to these currents in mutants lacking ALMT12.

Vicia faba TPC1, a genetically encoded variant of the vacuole Two Pore Channel 1, is hyperexcitable

This paper identifies a hyperexcitable variant of the TPC1 channel in Vicia faba, showing it differs from Arabidopsis in Ca2+ sensitivity and vacuole excitability.

Beet taproot plasma membrane sugar transport revisited

The paper identifies BvPMT5a and BvSTP13 as sugar transporters in sugar beet taproots, showing they mediate proton-driven glucose and sucrose uptake.

Ether anesthetics prevents touch-induced trigger hair calcium-electrical signals excite the Venus flytrap

This study shows that ether anesthetics suppress long-distance calcium and electrical signaling in Venus flytraps by targeting ion channels in the trigger hair, without affecting initial calcium signals.

The liverwort Marchantia polymorpha operates a depolarization-activated Slowpoke (SLO) K+ channel that recognises pH changes in the environment

This study identifies and characterizes a depolarization-activated K+ channel in the liverwort Marchantia polymorpha that responds to pH changes, suggesting a role in early plant adaptation to terrestrial environments.

Gaining or cutting SLAC: the evolution of plant guard cell signalling pathways

This study compares fern and angiosperm guard cell transcriptomes to explore the evolution of signaling pathways involved in stomatal closure, revealing conserved and divergent features.

PYL8 ABA receptors of Phoenix dactylifera play a crucial role in response to abiotic stress and are stabilized by ABA

This study identifies PdPYL8-like ABA receptors in date palm as key regulators of abiotic stress response, showing they are stabilized by ABA to enhance drought tolerance.

Action potentials induce biomagnetic fields in Venus flytrap plants

The paper investigates whether action potentials in Venus flytrap plants generate magnetic signals, finding that they do, with temporal characteristics similar to fast AP phases.

The developmental and genetic architecture of the sexually selected male ornament of swordtails

The paper identifies genes associated with sword development in swordtail fish by analyzing transcriptional profiles and genetic mapping.

GABA signalling in guard cells acts as a 'stress memory' to optimise plant water loss

This study identifies GABA as an endogenous plant signal that regulates stomatal movement and drought tolerance by inhibiting anion transporters in guard cells.
