  • Serine/Threonine Kinase
    Predominant plant receptor kinase class, mediating phosphorylation events distinct from animal Tyrosine Kinases.
  • Tyrosine Kinase
    Major animal receptor kinase class, less common in plants, central to many animal signaling pathways.
  • Receptor Kinase
    Membrane protein that initiates cellular responses upon binding specific signaling molecules in both plants and animals.
  • Auxin
    Plant signaling molecule crucial for stimulating growth and regulating developmental processes.
  • Ethylene
    Plant hormone responsible for promoting fruit ripening and mediating stress responses.
  • JAK-STAT Pathway
    Animal-specific signaling cascade absent in plants, involved in transmitting extracellular signals to the nucleus.
  • Notch Pathway
    Animal signaling mechanism, lacking in plants, essential for cell fate determination.
  • Wnt Pathway
    Animal-exclusive signaling route, not present in plants, regulating cell proliferation and differentiation.
  • Hedgehog Pathway
    Animal signaling system, missing in plants, critical for embryonic development and tissue patterning.
  • Stem Elongation
    Growth process in plants regulated by unique signaling molecules, enabling vertical extension.
  • Cell Division
    Fundamental process in plants controlled by specific signals, ensuring growth and tissue formation.
  • Dormancy
    Plant state regulated by signaling molecules, allowing survival during unfavorable conditions.
  • Light Sensing
    Plant ability to detect and respond to light, mediated by specialized signaling pathways.
  • Signaling Molecule
    Chemical agent in plants that triggers specific cellular responses, often unique compared to animals.
