Description
Plants build many key compounds from one shared pathway, and two branch chemicals sit near its end. Anya Franks and six co-authors tracked how fast those two chemicals, chorismate and isochorismate, turn over in Arabidopsis leaves in a 2026 study.
Using labeled carbon dioxide, the team watched fresh carbon move through leaf pools over minutes. Chorismate stayed mostly inside chloroplasts and renewed very fast, while isochorismate sat outside them in far larger amounts and renewed more slowly. A mutant plant that cannot export isochorismate lost most of its pool, which backs the picture. About a third of the chorismate pool, they calculate, flows on into isochorismate and toward salicylic acid, a defense signal.
