The study used transcriptomic profiling to compare tomato (Solanum lycopersicum) responses to three evolutionarily distant pathogens—nematodes, aphids, and oomycetes—during compatible interactions, identifying differentially expressed genes and key host hubs. Integrating public datasets and performing co‑expression and GO enrichment analyses, the authors mapped shared dysregulation clusters and employed Arabidopsis interactome data to place tomato candidates within broader networks, highlighting potential targets for multi‑pathogen resistance.

The study investigates the molecular basis of heat‑tolerant pollen tube growth in tomato (Solanum lycopersicum) by comparing thermotolerant and sensitive cultivars. Using live imaging, transcriptomics, proteomics, and genetics, the authors identified the Rapid Alkalinization Factor (RALF) signaling pathway as a key regulator of pollen tube integrity under high temperature, with loss of a specific RALF peptide enhancing tube integrity in a thermotolerant cultivar.

The study investigated three plastidial GGPP synthase isoforms in tomato, focusing on SlG2’s role in volatile isoprenoid production and disease resistance. CRISPR-edited slg2 mutants exhibited elevated geranyl diphosphate-derived monoterpenes and higher salicylic acid levels, leading to increased resistance against Pseudomonas syringae infection. The authors propose that SlG2 modulates GPP synthesis by competing for heterodimerization with SSU-I proteins.
