Summary
Barley
Area of Science:
- Plant immunity
- Molecular plant-pathogen interactions
- Proteomics and interactomics
Background:
- Barley MLA (NLR) receptors are crucial for fungal disease resistance.
- Understanding plant immune signaling networks is vital for crop improvement.
Purpose of the Study:
- To construct and analyze the barley protein interactome (HvInt) to explore MLA-associated signaling.
- To model cellular responses to powdery mildew infection using integrated datasets.
Main Methods:
- Interolog inference to build the barley protein interactome (HvInt).
- Integration of omics data (eQTL, RNA-seq) with HvInt.
- Comparative analysis with the Arabidopsis interactome.
Main Results:
- HvInt comprises 66,133 interactions and 7,181 nodes, sharing scale-free properties with Arabidopsis.
- Identified disease modules and responses linked to fungal penetration.
- Assembled resistant and susceptible subnetworks essential for barley immunity.
Conclusions:
- The study links genomic, transcriptomic, and physical interactions in MLA-specified immunity.
- HvInt serves as a foundation for dissecting plant immune signaling networks.
- Findings provide insights into barley's defense mechanisms against fungal pathogens.

01:19Interactions Between Signaling Pathways
6.6K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

02:26Protein Networks
4.1K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:11IP3/DAG Signaling Pathway
12.6K
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...

01:20The JAK-STAT Signaling Pathway
9.4K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
