Hormone-metabolic interactions in adventitious roots

Adventitious roots are roots that form after the plant embryo has grown. They're the roots that can grow out of stems when you make...

Calcium signaling regulates the protein VIP1 in touch responses in Arabidopsis

How can plants perceive mechanical stress such as touch? Calcium and several proteins are known to be involved, but it is still unclear how...

Asymmetric responses of the woody poplar taproot axis to bending stress

Mechanical bending stress can result in cell wall strengthening and increased wood formation across root axes together with an attendant asymmetrical accumulation of phytohormones....

Programmed cell death in cryo-exposed embryonic axes

A study of silver maple cools embryonic axes to liquid nitrogen temperatures without prior dehydration or cryoprotection treatments and thaws them rapidly.

Do changes in water levels in wetlands give plants a backbone?

The usual rule whenever a headline asks a silly question is that answer is no, and that's the same here because plants don't have...

Spotlight on macronutrients: Touchy-feely calcium…

Calcium (Ca) acts – amongst other things! – as a so-called ‘second messenger’, and participates in many processes of plant growth and development.

Biomechanics of aquatic plants under aerial conditions

Aquatic plants can be exposed to aerial conditions during periods of low water level, but their biomechanical responses to this have had little attention.
