Agronomists save tomatoes from toxic aluminum with melatonin

RUDN University agronomists and colleagues from China and Iran have helped tomatoes cope with the toxic effect of aluminum in acidic soils with the help of melatonin. This hormone contributes to nitric oxide production, blocking ...

High heat, ethylene levels independently halt tomato fruit set

Ethylene is an essential plant hormone at low concentrations. Concentrations in the field rarely exceed 5 nmol⋅mol−1 (0.005 ppm), but it can accumulate as a gas in closed, indoor environments. These elevated levels can ...

Developing drugs against drought

Abscisic acid (ABA) is a plant hormone with essential functions in plant physiology. It is involved in developmental and growth processes and the adaptive stress response. Thus, the plant adaptation to stress situations caused ...

Examining how plants steer clear of salt

To avoid salt in soil, plants can change their root direction and grow away from saline areas. University of Copenhagen researchers helped find out what makes this possible. The discovery changes our understanding of how ...

Discovery of family of hormones may be key to increased crop yields

Crops often face harsh growing environments. Instead of using energy for growth, factors such as disease, extreme temperatures, and salty soils force plants to use it to respond to the resulting stress. This is known as the ...
