Summary
Researchers developed PlantNexus, a new tool for exploring gene co-expression networks in barley and sorghum. This resource aids in understanding gene function and regulation in vital cereal crops.
Area of Science:
- Genomics
- Plant Biology
- Bioinformatics
Background:
- Global gene co-expression networks (GCNs) are crucial for inferring gene function and regulatory mechanisms.
- Cereal crops like barley (Hordeum vulgare) and sorghum (Sorghum bicolor) are vital but lack dedicated GCN tools.
- Existing RNA-seq data provides a foundation for network construction.
Purpose of the Study:
- To construct global and tissue-specific GCNs for barley and sorghum.
- To develop a user-friendly platform for accessing and visualizing these networks.
- To facilitate functional genomics research in important cereal crops.
Main Methods:
- Construction of global GCNs using existing RNA-seq datasets for barley and sorghum.
- Manual curation and categorization of meta-information by tissue type for tissue-specific GCNs.
- Implementation of a website and database (PlantNexus) for GCN searching and visualization.
Main Results:
- Successfully generated global GCNs for both barley and sorghum.
- Developed tissue-specific GCNs by curating meta-information.
- Launched PlantNexus, a freely accessible online resource for GCN exploration.
Conclusions:
- PlantNexus provides valuable GCNs for barley and sorghum, addressing a critical need in functional genomics.
- The platform enables efficient searching and visualization of gene co-expression data.
- This resource will advance research into gene function and regulation in cereal crops.

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.

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,...

01:25Cell Signaling in Plants
5.8K
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...

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...

02:16Light Acquisition
8.7K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

02:35Key Elements for Plant Nutrition
22.4K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
