Improving drought tolerance in rice: Ensuring food security through multi-dimensional approaches.

Area of Science:

• Agricultural Science
• Plant Biology
• Genetics

Background:

• Drought is a major threat to global food security, particularly impacting rice production in regions like Sub-Saharan Africa and Southeast Asia.
• Climate instability and unpredictable rainfall patterns exacerbate drought conditions, significantly reducing rice grain quality and yield.
• Rice, a C3 staple crop, exhibits complex traits for drought tolerance, making stress response understanding challenging.

Purpose of the Study:

• To review and integrate current knowledge on developing drought-tolerant rice.
• To explore strategies combining physiological adaptations, omics, and breeding approaches.
• To provide a comprehensive overview of efforts to enhance rice resilience to drought stress.

Main Methods:

• Literature review of physiological adaptations to drought stress in rice.
• Analysis of omics (genomics, transcriptomics, etc.) data for drought tolerance traits.
• Examination of transgenic and molecular breeding techniques for developing resilient rice varieties.

Main Results:

• Drought stress significantly reduces rice productivity and triggers acclimation responses.
• Understanding drought tolerance mechanisms in rice is complex due to intricate genetic and physiological factors.
• Integrative approaches combining omics and breeding have shown promise in developing stress-tolerant rice.

Conclusions:

• Developing drought-resilient rice requires an integrated strategy combining diverse scientific disciplines.
• Leveraging omics technologies and advanced breeding methods is crucial for enhancing rice drought tolerance.
• This review consolidates knowledge to guide future efforts in creating climate-resilient rice for sustainable agriculture.
