Description
Maria Paes and co-authors asked in 2026 whether grapevine cells grown in flasks can stand in for whole leaves when studying defence chemistry. Cell cultures are tidy and repeatable, but disease research in the end concerns real plants. Cells from two vine types, Cabernet Sauvignon and Chambourcin, were dosed with jasmonic acid, a plant stress hormone. Their chemistry was read two and five days later with an ultra-precise mass spectrometer, side by side with detached leaves.
Cultures and leaves kept clearly unlike chemical profiles, and responses varied by type and time in both systems. Yet on chosen ground the two met, above all in oxidative-stress defence, stress signalling, and secondary metabolite output. Flask cells can thus serve as a partner platform for switch-on responses, the authors conclude. Findings still need checking in intact plants, with key chemicals firmly named, before the stand-in is trusted.
