Description
Dikran Tsitsekian, Panagiota Mylona, and three colleagues chart when and where a model plant switches on the genes that make vitamin B2, in a paper published in two thousand twenty-five. The vitamin, riboflavin, is the raw material for two cofactors that power photosynthesis, respiration, and nitrogen use. Plants brew their own; animals must eat theirs.
The chemistry of the pathway was well mapped, but its regulation was not. The team mined large gene expression datasets for the thale cress Arabidopsis, adding co-expression analysis and a scan of the switches in front of each gene. They also measured actual flavin levels by chromatography as plants developed and faced stress. Expression shifted with both development and stress, in patterns the paper catalogs. Knowing how a plant tunes its vitamin supply matters for breeding and biofortification. It also completes a pathway biochemists thought they had finished.
