Description
Agustí, Martínez-Fuentes, Mesejo, Marzal, and Reig trace, published in 2024, the gene chain by which a sprayed plant hormone thins citrus fruit. The synthetic auxin 3,5,6-TPA is sprayed as young fruit naturally begin to drop. Treated trees drop more fruitlets and carry fewer, larger fruit to harvest. The team tracked sugar genes in leaf and fruit to find the mechanism. The spray acts through the leaves first.
Leaf genes for carbon capture and sugar making switched down. Sugar mover genes fell too, so less sugar reached the fruit. In the fruit, sugar-splitting and cell-division genes were repressed as well, along with auxin-handling genes. Starved of sugar and division signals, the fruit raised ethylene, the gas that triggers drop. The authors map a full leaf-to-fruit chain for a tool growers already use, opening ways to tune dose and timing.
