The study investigates how Arabidopsis thaliana rosette leaves respond to iron availability at four successive reproductive stages, showing that young leaves suffer growth inhibition and yellowing under iron deficiency while old and young leaves display distinct gene expression and elemental profiles. Developmental stage‑dependent modulation of iron‑related genes and ionomic contents is highlighted, suggesting leaf‑specific signaling mechanisms in iron management.

A biparental Vicia faba mapping population was screened under glasshouse conditions for resistance to a mixture of Fusarium avenaceum and Fusarium oxysporum, revealing several families with moderate to high resistance. Using the Vfaba_v2 Axiom SNP array, a high-density linkage map of 6,755 SNPs was constructed, enabling the identification of a major QTL on linkage group 4 associated with partial resistance to foot and root rot.

The study characterizes all seven malic enzyme genes in tomato, analyzing their tissue-specific expression, temperature and ethylene responsiveness, and linking specific isoforms to metabolic processes such as starch and lipid biosynthesis during fruit development. Phylogenetic, synteny, recombinant protein biochemical assays, and promoter analyses were used to compare tomato enzymes with Arabidopsis counterparts, revealing complex evolutionary dynamics that decouple phylogeny from functional orthology.
