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. Content type: Review

    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...

  2. Content type: Question and Answer

    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 ...

  3. Content type: Question and Answer

    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 ...

  4. Content type: Question and Answer

    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...

  5. Content type: Research article

    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...

    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...

  7. Content type: Question and answer

    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...
