Summary
The ubiquitin-proteasome system is vital for cell regulation. This review details how Cullin-RING Ligase 3 (CRL3) ubiquitin ligases and their adaptors control plant processes, highlighting their cooperation with other E3s.
Area of Science:
- Molecular Biology
- Plant Science
- Biochemistry
Background:
- The ubiquitin-proteasome system (UPS) is crucial for eukaryotic cellular regulation.
- Ubiquitin-protein ligases (E3s) confer substrate specificity in ubiquitylation.
- Cullin-RING Ligases (CRLs) are a major class of E3s, with SCF and CRL3 complexes being prominent examples.
Purpose of the Study:
- To review the diverse roles of CRL3 E3s in plants.
- To explore the variety of CRL3 complexes and their regulated processes.
- To illustrate potential cooperation between different E3 ligase classes.
Main Methods:
- Literature review of research on plant E3 ubiquitin ligases.
- Analysis of the structural components and functions of CRL3 complexes.
- Synthesis of findings on CRL3-mediated regulation and E3 cooperation.
Main Results:
- CRL3s, comprising CUL3 and BTB/POZ adaptors, play essential roles in plants.
- CRL3s regulate a wide spectrum of plant biological processes.
- Evidence suggests functional cooperation between different E3 ligase families.
Conclusions:
- CRL3 E3 ubiquitin ligases are key regulators in plant cellular functions.
- Understanding CRL3 diversity and function is critical for plant science.
- Investigating E3 ligase cooperation offers insights into complex regulatory networks.

Cell Signaling in Plants
6.0K
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...

C4 Pathway and CAM
47.8K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

Cell Adhesion in Plants
3.0K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

Short-distance Transport of Resources
17.0K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.
