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 ...

A paper describes how the moving parts of a particular plant protein control whether plants can grow and make energy-intensive products such as oil -- or instead put in place a series of steps to ...

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 ...

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 ...

ITHACA, N.Y. -- Goldenrod can perceive other plants nearby without ever touching them, by sensing far-red light ratios reflected off leaves. When goldenrod is eaten by herbivores, it adapts its ...

A pioneering study led by researchers at Tel Aviv University has uncovered the world's first documented case of acoustic communication between plants and insects, revealing that female moths can hear ...

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