Summary
Brassinosteroids (BRs) signaling impacts crop yield, quality, and nutrition. Understanding BR networks offers a framework for improving multiple crop traits simultaneously.
Area of Science:
- Plant Biology
- Agricultural Science
- Molecular Biology
Background:
- Brassinosteroids (BRs) are crucial plant hormones regulating growth and development.
- BR signaling influences key agricultural traits, including yield, quality, and nutritional value.
- Understanding BRs is vital for food security and consumer preferences.
Purpose of the Study:
- To review recent advances in BR-mediated signaling networks.
- To explore how BRs control crop architecture, size, shape, quality, and nutrition.
- To provide a framework for improving crop traits through BR manipulation.
Main Methods:
- Literature review of recent studies on brassinosteroid signaling.
- Synthesis of mechanistic and translational research findings.
- Analysis of BR interactions with other hormonal pathways and natural variation.
Main Results:
- BR signaling networks control panicle architecture and grain/fruit size and shape.
- Targeted manipulation of BR components can enhance yield, quality, and nutrition.
- Interactions with other pathways and natural variation offer further optimization strategies.
Conclusions:
- BR signaling is a key target for improving yield, quality, and nutritional value.
- A conceptual framework is provided for the rational exploration of BR signaling in crops.
- Future research should focus on harnessing BRs for simultaneous trait improvement.

Cell 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...
Plant Hormones
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Plant 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.
Bioreactor Controls-III
Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...
Key Elements for Plant Nutrition
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 atmosphere, the...
