Short-term exposure to elevated temperature and CO₂ alters phytoestrogen production in red clover.

ABSTRACT: Phytoestrogens are plant-produced secondary compounds that mimic the animal sex hormone estrogen. Several legumes, including red clover, produce phytoestrogens as stress defense molecules, and climate change-driven increases in atmospheric temperature and CO₂ may intensify their production. We conducted a growth chamber study to determine the effects of short-term exposure to elevated temperature (eT) and CO₂ (eCO₂), both alone and in combination, on phytoestrogen concentrations in red clover and cowpea. Plants were grown in ambient conditions (24/18 °C, day/night, and ~ 400 ppm CO₂) and then exposed to eT (35/26 °C, day/night), eCO₂ (750 ± 50 ppm), or both factors for 10 days.
