Microbe-Plant Interactions01:09

Microbe-Plant Interactions

101
Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...

Defenses Against Pathogens and Herbivores

30.1K
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.

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...

IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

16.2K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Plant Cell Wall02:43

Plant Cell Wall

62.0K
The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Morphogenesis02:19

Morphogenesis

30.9K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

  • Plant immunity and signaling

Background:

  • TCP gene family encodes plant-specific transcription factors.
  • TCP factors regulate growth, development, hormonal pathways, and signaling cascades.
  • Recent findings indicate TCP factors are targets of pathogenic effectors and crucial for plant immunity.

Purpose of the Study:

  • Review the role of TCP factors in plant immunity.
  • Explore the convergence of effectors, hormonal networks, and the circadian clock in TCP-mediated plant defense.
  • Elucidate potential mechanisms of pathogen defense involving TCP factors.

Main Methods:

  • Literature review and synthesis of existing research on TCP gene family functions.
  • Analysis of interactions between TCP factors, hormonal pathways, and pathogen effectors.
  • Exploration of the circadian clock's role in plant immunity.

Main Results:
