Description
Marcelo de Almeida Guimarães, leading six colleagues, published a 2026 laboratory study of selenium enrichment in sweet potato plantlets grown in culture. Selenium deficiency affects roughly a billion people, and biofortifying crops is one proposed fix. Explants grew in hormone-free medium dosed with sodium selenate from zero to twenty-five micromolar, and the team measured growth, photosynthetic pigments, and selenium uptake.
The lowest dose gave the best growth, with the most leaves, longest shoots and roots, and highest dry biomass, plus peak chlorophyll and carotenoid levels in the reported results. Higher doses progressively stunted growth and pigments, showing toxicity, while tissue selenium kept climbing with dose. The authors recommend the low dose for propagation and higher doses only as a starting point for biofortification work.
