Soybean Inositol Polyphosphate 5‐Phosphatase 8 Confers Salt Tolerance by Reducing Sodium Influx Through Inositol 1,4,5‐Trisphosphate Signalling

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Evidence suggests that the metabolism of inositol and its derivatives may be involved in various biological processes including salt tolerance, but there has been limited understanding. Ectopic expression of Gs5PTase8, an inositol polyphosphate 5‐phosphatase cloned from wild soybean (Glycine soja), significantly enhanced salt tolerance in ...

Arbuscular Mycorrhiza Modulates Iron Distribution and Vacuolar Iron Transporter Expression in Tomato, Whereas Iron Limitation Reduces Mycorrhization

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plants have evolved highly efficient strategies to maintain iron (Fe) homeostasis. In this study, we investigate the impact of arbuscular mycorrhizal (AM) symbiosis on the Fe‐deficiency response and ionomic profile of tomato plants, as well as how Fe availability affects AM symbiosis.

Drought affects Fe deficiency‐induced responses in a purple durum wheat (Triticum turgidum subsp. durum) genotype

open access: yesPlant Biology, EarlyView.
Combined Fe deficiency and drought in durum wheat trigger interactive responses: drought suppressed root Fe uptake regardless of Fe availability, and both stresses altered phytosiderophore release, ABA level and Fe transporter gene expression, revealing a trade‐off between water and Fe. Abstract Iron (Fe) is essential for plants and humans, with over 2

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

open access: yesPlant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Tariff: The Most Beautiful Word in the Dictionary?

open access: yesReview of International Economics, EarlyView.
ABSTRACT We consider the welfare impacts of US tariff policy at levels proposed by President Donald J. Trump. General‐equilibrium simulations under a widely used transparent one‐sector trade model reveal sizable US welfare losses. When we extend the model to include bilateral firm selection and high resolution input–output linkages, the US losses ...

Integrating Global Citizenship Into Mathematics Education: Development and Validation of a Scenario‐Based Assessment

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study develops and validates a scenario‐based assessment for global citizenship within mathematics contexts. It addresses the need for students to engage thoughtfully with global challenges by linking civic education and mathematics. The assessment tool captures competencies essential for global citizenship, including presenting opinions ...
