Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Evaluating the Combined Effects of Elevated [CO2] and Accelerated NPQ Relaxation on Yield, Physiology and Transcription in Soybean

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Improving photosynthesis is proposed as a means of enhancing crop productivity. To assess whether simultaneous increases in light use‐efficiency and carbon assimilation are additive, we investigated the impact of elevated CO2 on the performance of a transgenic soybean line engineered for faster relaxation of photoprotection by overexpression ...

Sulphur‐mediated iron homeostasis in four tetraploid wheats (Triticum turgidum L.)

open access: yesPlant Biology, EarlyView.
Polish wheat's tolerance to S limitation enables a well‐orchestrated response for efficient Fe acquisition when S is scarce, involving increased Fe accumulation, enhanced phytosiderophore release, and upregulated TdIRO2 and TdYSL15 expression. Abstract Sulphur (S) deficiency is known to hinder iron (Fe) uptake and distribution in wheat, mainly by ...

Time‐ and cultivar‐dependent biochemical responses to heat priming and stress in rice

open access: yesAnnals of Applied Biology, Volume 189, Issue 1, July 2026.
Global warming increasingly threatens rice productivity, and understanding the biochemical mechanisms underlying heat stress responses is crucial for developing resilient cultivars. By demonstrating that stress responses are both cultivar‐ and time‐of‐day‐dependent, our findings offer new insights into the temporal and genetic regulation of acquired ...

Genome‐wide analysis of DNA methyltransferases in a model extremophyte, Schrenkiella parvula: Transcriptional dynamics during development and under salt stress

open access: yesAnnals of Applied Biology, Volume 189, Issue 1, July 2026.
Classification of DMTs into 4 subfamilies: two METs, three CMTs, three DRMs, and one DNMT2. The cis‐elements are associated with stress‐response, hormonal regulation, light‐response, and development. RNA‐seq analysis revealed differential expression of DMTs under NaCl stress.
