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. Review

    Life behind the wall: sensing mechanical cues in plants

    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. Question and Answer

    Q&A: what are brassinosteroids and how do they act in plants?

    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 ...

  3. Question and Answer

    Q&A: How does jasmonate signaling enable plants to adapt and survive?

    Jasmonates (JAs) are a class of plant hormones that play essential roles in response to tissue wounding. They act on gene expression to slow down growth and to redirect metabolism towards producing defense mol...

  4. Question and Answer

    Q&A: Auxin: the plant molecule that influences almost anything

    Auxin is an essential molecule that controls almost every aspect of plant development. Although the core signaling components that control auxin response are well characterized, the precise mechanisms enabling...

  5. Question and Answer

    Q&A: How does peptide signaling direct plant development?

    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. Research article

    Comparative analysis of plant immune receptor architectures uncovers host proteins likely targeted by pathogens

    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. Question and Answer

    What are karrikins and how were they ‘discovered’ by plants?

    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. Question and answer

    Q&A: How do plants sense and respond to UV-B radiation?

    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...
