Cell Signaling in Plants01:25

Cell Signaling in Plants

7.1K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Regulation of Transpiration by Stomata

32.3K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Defenses Against Pathogens and Herbivores

30.0K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Protein Transport to the Stroma

2.3K
Chloroplasts are triple membrane structures with an outer membrane, an inner membrane, and a thylakoid membrane, each containing distinct metabolite transporters, membrane translocons, and enzymes. Appropriate sorting and translocating these proteins to their correct membrane systems is essential for chloroplast function.
Protein complexes called the translocon of the outer chloroplast membrane or TOC complex, and the translocon of the inner chloroplast membrane or TIC complex mediate the...

Antigen Processing Pathways

3.0K
MHC molecules are key players in the immune response, enabling T cells to recognize and respond to specific antigens. They are present on the surface of all nucleated cells in the body and are instrumental in presenting antigens to T cells and activating them. T cells recognize the MHC-antigen complex and initiate an immune response. MHC class I and MHC class II are two main types of MHC molecules, each associated with a distinct antigen processing pathway.

Area of Science:

  • Plant biology
  • Plant pathology
  • Molecular plant-microbe interactions

Background:

  • Pathogen infection commonly induces local stomatal closure in plants, a key defense mechanism.
  • The systemic effects of local infections on distant stomatal responses were previously uncharacterized.

Purpose of the Study:

  • To investigate whether local pathogen infection can induce stomatal closure in non-infected, distant leaves.
  • To identify the molecular mechanisms underlying systemic stomatal regulation during plant-pathogen interactions.

Main Methods:

  • Utilized plant physiological measurements to assess stomatal aperture in local and distant leaves following pathogen inoculation.
  • Employed molecular genetics and biochemical assays to identify signaling molecules and their receptors involved in the systemic response.

Main Results:

  • Demonstrated that local infection significantly induces stomatal closure in distant leaves, indicating a systemic immunity signal.
  • Identified a novel mobile peptide encoded by an upstream open reading frame (uORF) as a key mobile signal.
  • Characterized a specific receptor-coreceptor pair that perceives this mobile peptide to activate systemic stomatal immunity.

Conclusions:

  • Local pathogen infection elicits a long-distance signaling cascade that culminates in systemic stomatal closure.
  • The uORF-encoded mobile peptide and its receptor-coreceptor system represent a novel pathway for regulating plant immunity.
  • This discovery sheds light on the complex systemic defense strategies employed by plants to combat pathogens.
