Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, Volume 106, Issue 15, Page 8977-8991, December 2026.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Investigation of Indolglyoxamide and Indolacetamide Analogues of Polyamines as Antimalarial and Antitrypanosomal Agents

Marine Drugs, 2014
Pure compound screening has previously identified the indolglyoxy lamidospermidine ascidian metabolites didemnidine A and B (2 and 3) to be weak growth inhibitors of Trypanosoma brucei rhodesiense (IC50 59 and 44 μM, respectively) and Plasmodium ...

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha

New Phytologist, Volume 252, Issue 5, Page 1943-1961, December 2026.
The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

Effects of severe drought stress on the physiology and biochemistry characteristics of Welsh onion (Allium fistulosum L. var. giganteum Makino) seedlings

Horticultural Science, 2023
The physiological regulation of Welsh onion seedlings was explored under short- and long-term drought stress. The Welsh onion cultivar 'Neicong 3' was grown in pots under drought stress (22.5-25% soil water content) or controlled watering conditions (65 ...

Repurposing a Small Molecule Plant Hormone as a Tunable ON‐Switch for CAR‐T Cell Immunotherapy

Advanced Science, Volume 13, Issue 61, 3 November 2026.
By engineering a receptor system integrating the plant auxin receptor AFB1 with its co‐receptor IAA7, we enable ligand‐dependent interactions triggered by the plant hormone auxins. This design allows rapid, reversible, and dose‐dependent T cell activation, resulting in potent cytotoxicity against B‐cell lymphoma in vitro and in vivo.

Polyphenol‐Rich Foods as a Healthy and Sustainable Strategy: Mental Health and Metabolomic Profiling

Molecular Nutrition &Food Research, Volume 70, Issue 19, 15 October 2026.
A 12‐week nutritional intervention with cocoa flavanols and red‐berry anthocyanins in older adults improved emotional well‐being and identified metabolomic signatures associated with the intervention through urinary metabolome profiling. ABSTRACT The so‑called demographic transition has increased the prevalence of chronic diseases in adults over 65 ...
