Description
Ramos-Alvelo and six co-authors studied a tomato root receptor in twenty twenty-four that keeps a helpful fungus partnership in check. Most land plants trade nutrients with soil fungi through finely branched structures inside their roots, and one receptor, SlDLK2, limits how much those branches grow.
The team raised tomato plants that overproduce the receptor and read their root genes and hormone levels. Genes for making several hormones were turned down in those roots. Two hormones tied to the partnership, jasmonic acid and abscisic acid, dropped steeply. Plant auxin and one fungal-signal compound also dipped slightly. The pattern suggests the receptor restrains the partnership by starving it of the hormones that promote it. Understanding this brake could help breeders tune how strongly crops engage their fungal partners. That balance affects how much fertilizer a crop needs.
