The study performed a comprehensive computational analysis of the Arabidopsis thaliana proteome, classifying 48,359 proteins by melting temperature (Tm) and melting temperature index (TI) and linking thermal stability to amino acid composition, molecular mass, and codon usage. Machine‑learning and evolutionary analyses revealed that higher molecular mass and specific codon pairs correlate with higher Tm, and that gene duplication has driven the evolution of high‑Tm proteins, suggesting a genomic basis for stress resilience.

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 shows that drought triggers ABA accumulation and JA reduction in sorghum roots, accompanied by transcriptional activation of genes linked to mineral homeostasis, hormone signaling, and osmotic regulation, while Fe supplementation enhances ferritin expression and mitigates oxidative stress. Drought also diminishes root bacterial diversity but enriches beneficial taxa such as Burkholderia, whereas fungal diversity remains stable, and functional profiling reveals shifts toward phototrophy, methylotrophy, and nitrate reduction. These findings highlight ferritin’s protective role and suggest specific bacterial inoculants for improving sorghum drought resilience.
