The researchers created tomato lines overexpressing the autophagy gene SlATG8f and evaluated their performance under high-temperature stress. qRT‑PCR and physiological measurements revealed that SlATG8f overexpression enhances expression of autophagy‑related and heat‑shock protein genes, accelerates fruit ripening, and improves fruit quality under heat stress.

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.
