Sugarcane faces significant yield loss from waterlogging stress. Understanding its physiological and molecular responses is key to developing flood-tolerant varieties for improved crop resilience.
Area of Science:
- Agricultural Science
- Plant Physiology
- Stress Biology
Background:
- Sugarcane (Saccharum officinarum) is a vital global crop for sugar and bioenergy production.
- Abiotic stresses, such as waterlogging, negatively impact sugarcane growth and yield, causing reductions of 15-45%.
Purpose of the Study:
- To review recent findings on sugarcane adaptation to waterlogging stress.
- To elucidate the physiological, biochemical, and molecular mechanisms underlying sugarcane's response to flooding.
Main Methods:
- Literature review of studies on sugarcane waterlogging tolerance.
- Analysis of physiological, biochemical, and molecular data related to stress responses.
Main Results:
- Waterlogging significantly reduces sugarcane growth, survival, yield, and quality.
- Plant responses to waterlogging involve complex, dynamic, and potentially reversible molecular, cellular, and physiological changes.
Conclusions:
- Understanding sugarcane's adaptive mechanisms to waterlogging is crucial for developing stress-resilient cultivars.
- Breeding strategies can be enhanced by insights into the biochemical and adaptive-molecular processes contributing to flooding tolerance.
