Summary
The CoP database links co-expressed gene modules from plant microarray data with biological information. This resource aids in understanding gene function and pathways in key plant species.
Area of Science:
- Plant genomics
- Bioinformatics
- Systems biology
Background:
- Gene co-expression analysis is crucial for understanding gene function.
- Publicly available plant microarray data offers a rich resource for such analyses.
- Integrating gene modules with biological annotations enhances functional interpretation.
Purpose of the Study:
- To develop the CoP database for associating co-expressed gene modules with biological information.
- To provide a centralized resource for plant gene co-expression network analysis.
- To facilitate functional genomics research in plants.
Main Methods:
- Utilized a large dataset of 10,022 plant microarray assays.
- Applied the Confeito algorithm to extract co-expressed gene modules based on gene interconnectivity.
- Integrated gene modules with Gene Ontology terms and metabolic pathway information.
Main Results:
- Developed the CoP database, a comprehensive resource for plant gene co-expression modules.
- The database includes gene modules for Arabidopsis thaliana and seven major crops.
- Successfully associated co-expressed gene modules with functional annotations.

01:25Cell Signaling in Plants
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...
02:50Transgenic Plants
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

01:59Plant Breeding and Biotechnology
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
01:27Constitutive and Regulated Gene Expression
Gene expression in prokaryotes is governed by constitutive and regulated systems, allowing cells to balance the production of essential proteins with adaptive responses to environmental changes.Constitutive Gene ExpressionConstitutive, or housekeeping, genes are continuously expressed as they encode proteins vital for fundamental cellular processes. These include enzymes for glycolysis, ribosomal components for protein synthesis, and proteins involved in DNA replication. Their constant...
01:29Coordination of Gene Expression Processes in Bacteria
The DNA replication, transcription, and translation processes are intricately coupled in bacteria, allowing efficient gene expression and rapid protein synthesis. While this physical and functional coordination is advantageous, it introduces challenges that bacteria overcome through specific regulatory mechanisms.Coupling of Replication, Transcription, and TranslationThe coupling of replication, transcription, and translation is a hallmark of bacterial gene expression. As the replisome unwinds...
01:58Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
