What to know about X-ray analysis reveals the inner life of leaves while advancing engineering efforts to reduce 'crop sweat'

Researchers from the University of Illinois Urbana-Champaign used high-resolution micro-computed tomography at Argonne National Laboratory to map the internal anatomy of sorghum leaves. The study found that reducing the number of stomata to prevent water loss does not necessarily hinder carbon dioxide intake, potentially aiding the development of drought-resistant crops.

What happened

X-ray analysis reveals the inner life of leaves while advancing engineering efforts to reduce 'crop sweat' Gaby Clark Scientific Editor Robert Egan Senior Editor In the Midwestern summer, humans and plants have to breathe through the heat and humidity.

Why it matters

Researchers hope that a retooled crop plant—one with an improved ventilation system within its leaves—could thrive while avoiding drought stress by reducing "crop sweat." Thanks to next-generation imaging technology powered by Argonne National Laboratory's…

Common ground

The research, published in Plant Physiology, was led by postdoctoral researcher James Fischer in the laboratory of plant biology and crop sciences professor Andrew Leakey at the University of Illinois Urbana-Champaign.

Claim 1: “For each molecule of CO2 that enters the plant through the stomata to be captured by photosynthesis, 300–400 water molecules escape from the interior of the leaf through the stomata to the atmosphere.”
CORROBORATED
Multiple sources confirm the trade-off between CO2 gain and water loss. Specifically, one source explicitly mentions '400 water molecules lost for each CO2 molecule gained', which aligns with the 300-400 range mentioned in the claim.
