Description

Da-Gang Hu and co-authors published a plant study in 2024 on why malic acid builds up in apple fruit. Malic acid helps give apples their tart taste. The team asked how sorbitol, a sugar form made in leaves, turns on the genes that move malate into storage space inside fruit cells.

Blocking one sorbitol gene lowered both sorbitol and malate in fruit and leaves. The team then found a linker histone, MdH1.1, that acts like a switch and turns on three partner genes. One partner turns the switch back on, so the pair form a loop that reads the sorbitol signal. Raising or lowering the switch changed malate levels, which shows how sugar signals guide fruit taste.
