Using newly generated 'optogenetic' tobacco plants, research teams have investigated how plants process external signals. When it comes to survival, plants have a huge disadvantage compared to many ...

Cytokinin signalling remains a central focus in plant biology due to its vital role in regulating cell division, meristem maintenance and overall plant architecture. Recent investigations have ...

Last night's session (February 12) on hormones networks at the joint Keystone meeting on plant signaling and immunity in Keystone, Co, began with Charlie Chaplin. Specifically, the audience was ...

Auxin, a pivotal plant hormone, orchestrates a wide range of developmental processes including cell division, elongation, organ formation and responses to environmental stimuli. Its signalling ...

Dear EarthTalk: Is it true that plants communicate by sending chemical signals through the air? -- Melissa, via email Recent ...

Plants do not stay silent. New research shows how plant diversity changes smell based communication across ecosystems.

Researchers at the Max Planck Institute for Chemical Ecology and the University of Kiel have provided experimental evidence ...

A recent study reveals how plants activate a reactive oxygen species (ROS)-driven signaling pathway to adapt to low nitrate conditions. Researchers identified RBOHC as the primary ROS producer, which ...

Researchers have shown that certain plant proteins resemble human signaling proteins of the immune system and can bind to their receptors. The human immune system is based on cells that communicate ...

Researchers at Purdue University and UC Davis have found that petunias cannot properly form reproductive structures without chemical signals delivered between different parts of the plant. The work ...

Signals transmitted via leaves can warn neighboring plants of stressful events, making the group collectively more resilient ...
