Auxin response and PIN‐mediated transport in chlorophyte algae

open access: yesJournal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Generation and Care of Xenopus laevis and Xenopus tropicalis Embryos [PDF]

open access: yes, 2018
Robust and efficient protocols for fertilization and early embryo care of Xenopus laevis and Xenopus tropicalis are essential for experimental success, as well as maintenance and propagation of precious animal stocks. The rapid growth of the National Xenopus Resource has required effective implementation and optimization of these protocols.

The Dual‐Function of CtrNAC019‐CtrNPF2.1 Module in Salt Tolerance and Nitrogen Use Efficiency Via Enhancing Vacuolar Chloride Sequestration and Nitrate Efflux in Citrus trifoliata

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Salt stress and nitrogen utilisation efficiency (NUE) represent critical constraints affecting worldwide crop productivity. While nitrate transporter proteins (NPFs) have been implicated in saline chloride (Cl−) ion transport, the mechanistic linkage between chloride stress and NUE remains poorly understood.

Migratory and adhesive properties of Xenopus laevis primordial germ cells in vitro

open access: yesBiology Open, 2013
Summary The directional migration of primordial germ cells (PGCs) to the site of gonad formation is an advantageous model system to study cell motility.

The CaM1‐CBP60b‐MYB77 Transcriptional Cascade Regulates K+ Homeostasis and Salt Tolerance in Barley

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Soil salinity is a major abiotic stress that threatens global crop productivity. Calcium (Ca2+) is a pivotal second messenger in plant stress signalling, but how Ca2+ sensors such as calmodulin (CaM) transcriptionally control ion homeostasis and salt tolerance remains largely understood in crops.

Early Head Specification in Xenopus laevis

open access: yesThe Scientific World Journal, 2003
The head represents the most dorsal and anterior extent of the body axis. In Xenopus, the progressive determination of the head is an extremely complex process involving the activation and localized antagonism of a number of interdependent intracellular ...

Photochemistry of CryB from Rhodobacter sphaeroides

open access: yesPhotochemistry and Photobiology, EarlyView.
Elucidation of the photochemistry of CryB from Rhodobacter sphaeroides was achieved from the nanosecond to second timescale. A fast (<5 ns) deprotonation of the terminal electron donor Trp338 and the involvement of Tyr337 in photoreduction have been revealed.

The Many Faces of Xenopus: Xenopus laevis as a Model System to Study Wolf–Hirschhorn Syndrome

open access: yesFrontiers in Physiology, 2019
Wolf–Hirschhorn syndrome (WHS) is a rare developmental disorder characterized by intellectual disability and various physical malformations including craniofacial, skeletal, and cardiac defects.

MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.
