Plant Signals

 Consulting Editors: Elliot Meyerowitz, Wolf Frommer, Virginia Walbot

Plant growth and development are regulated by the plant hormones, small-molecule metabolites that have evolved signaling functions. Plants also respond with changes in morphology and physiology to a remarkable range of external signals - light, of course, and many others, including temperature, moisture, infection, and touch. For this series, we have invited Q&As on established and less well established plant signaling pathways, reflecting what is known and what is still to be discovered.

We welcome research submissions on the many open questions that remain to be answered in plant signaling.

  1. In plants, the shoot apical meristem (SAM) has two main functions, involving the production of all aerial organs on the one hand and self-maintenance on the other, allowing the production of organs during the ...

  2. There is increasing evidence that all cells sense mechanical forces in order to perform their functions. In animals, mechanotransduction has been studied during the establishment of cell polarity, fate, and di...

  3. Salicylic acid (SA) is an important plant hormone that regulates many aspects of plant growth and development, as well as resistance to (a)biotic stress. Efforts to identify SA effector proteins have revealed ...

  4. Brassinosteroids (BRs) are a class of polyhydroxylated steroidal phytohormones in plants with similar structures to animals’ steroid hormones. Brassinosteroids regulate a wide range of physiological processes ...

  5. A significant part of the communication between plant cells is mediated by signaling peptides and their corresponding plasma membrane-localized receptor-like kinases. This communication mechanism serves as a k...

  6. Plants deploy immune receptors to detect pathogen-derived molecules and initiate defense responses. Intracellular plant immune receptors called nucleotide-binding leucine-rich repeat (NLR) proteins contain a c...

  7. Karrikins are a family of compounds produced by wildfires that can stimulate the germination of dormant seeds of plants from numerous families. Seed plants could have ‘discovered’ karrikins during fire-prone t...

  8. Plants are able to sense UV-B through the UV-B photoreceptor UVR8. UV-B photon absorption by a UVR8 homodimer leads to UVR8 monomerization and interaction with the downstream signaling factor COP1. This then i...
