Plant Signaling
Every stress response your tomatoes show — wilting, yellowing, that sudden bolt to seed — is driven by hormone signals this method can now read in a single 10-minute snapshot, giving growers a precise chemical vocabulary for what their plants are actually saying.
Plants use chemical messengers called hormones to control growth, fight off bugs and diseases, and cope with drought or heat. Until now, measuring all these messengers at once required lots of plant material and took a long time. This new lab technique reads 27 different plant hormones from a tiny sample — about the weight of a small pinch of dried herb — in just 10 minutes.
Key Findings
27 phytohormones across multiple classes (including 18 gibberellins, abscisic acid, salicylic acid, auxin, and jasmonates) can be quantified in a single 10-minute run.
The method requires only 20 mg of plant material — roughly the weight of a few seeds — making it practical for small or precious samples.
Detection limits ranged from 0.04 to 29.9 nM, and the method was validated on three crop/food plants: tomato, maize, and cress.

Scientists developed a fast, sensitive test that can measure 27 different plant hormones simultaneously from just a tiny pinch of plant material in 10 minutes — far more efficient than previous methods.
