Biologists discover a previously unknown salt tolerance mechanism in plants

Researchers have uncovered a novel salt tolerance mechanism in plants. They discovered that the chloride channel protein AtCLCf moves to the plasma membrane to remove excess chloride ions under salt stress, enhancing salinity tolerance. This finding could help improve crop…

New tomato, potato family tree shows that fruit color and size evolved together

Researchers have created an improved family tree for Solanum plants, revealing that fruit color and size evolved together, challenging previous theories that fruit-eating animals were the primary drivers. This study offers insights for breeding better crops.

Scientists Discover Forests That May Resist Climate Change

Researchers discovered forests with cold-air pooling, where colder air settles in valleys, reversing typical temperature patterns. These areas could protect cold-adapted species from climate change, serving as refuges and aiding conservation efforts. The study emphasizes the importance of such forests…

Image: Plant defense priming in response to herbivory. Primer stimuli are environmental cues (e.g. volatile organic compounds from damaged neighboring plants, direct herbivore damage, spectral and chemical information) that elicit plant endogenous signaling and so ready plants for faster and stronger responses when additional attacks by herbivores occur (trigger stimulus). Intensity of the priming stimulus and the plant’s inherit sensitivity determine how strongly the plant is responding to a stimulus, reaching from alterations in endogenous signaling that may not significantly affect metabolism to a direct induction of defense metabolism. If the endogenous signal intensity elicit by environmental stimuli ranges within a critical signal intensity, a subsequent trigger stimulus (e.g. direct damage by a herbivore) will result in a faster and stronger expression of the plant defense metabolism. The reliability of a priming stimulus as a predictor of subsequent fitness-affecting damage will affect endogenous signal intensity and retention and thus if the priming information is stored in short- (e.g. transient, transcript and phytohormone accumulation) or long-term memory (e.g. epigenetic alterations). Defense priming allows the integration of environmental information to optimize plant responses while minimizing the costs associated with unreliable (false) environmental information.

Are plants intelligent? It depends on the definition

Goldenrod plants exhibit adaptive responses to environmental cues, such as perceiving nearby plants through far-red light and changing behavior when attacked by herbivores. This ability to solve problems and adjust based on environmental information is argued to fit a very…
