Description
Yunfei Liang and co-authors identify a tomato gene that trades growth and ripening against cold tolerance. Their 2026 study characterizes SlBBX19, a transcription factor switched on by chilling. Cold snaps sharply limit tomato farming, so the genes that balance yield and hardiness are valuable targets.
Plants with extra copies of the gene grew slower and photosynthesized less in normal weather, yet ripened fruit faster. Under chilling, those plants suffered more damage, while plants with the gene knocked out resisted cold better. The factor binds the switches of two light-harvesting genes and turns them down. Silencing those targets copied the overexpression effects. The authors propose the gene as a breeding target.
