Non-coding RNAs (ncRNAs) are key regulators of seed endosperm development, influencing crucial processes like cell growth and nutrient accumulation. Understanding these ncRNAs offers potential for improving crop yield and quality through precision breeding.
Area of Science:
- Plant Biology
- Molecular Genetics
- Epigenetics
Background:
- The endosperm, a vital nutritive tissue in seeds, is essential for embryo development, grain yield, and quality.
- Non-coding RNAs (ncRNAs) are increasingly recognized as central regulators integrating epigenetic, transcriptional, and post-transcriptional control in endosperm development.
Purpose of the Study:
- To review current understanding of ncRNA-mediated regulation in endosperm development.
- To highlight the potential of ncRNAs for crop improvement strategies.
Main Methods:
- Literature review synthesizing recent advances in endosperm biology and ncRNA research.
- Analysis of the roles of small RNAs (sRNAs) and long non-coding RNAs (lncRNAs) in endosperm processes.
Main Results:
- Small RNAs (microRNAs, siRNAs) regulate endosperm cell proliferation, starch synthesis, and transposon silencing.
- Long non-coding RNAs (lncRNAs) are involved in cellularization, nutrient accumulation, and genomic imprinting.
- ncRNAs modulate hormonal pathways, metabolic processes, and chromatin remodeling.
Conclusions:
- Functional characterization of ncRNAs in endosperm biology is limited but crucial.
- ncRNAs represent promising targets for enhancing crop traits and optimizing grain quality.
- Future research should integrate ncRNA networks with multi-omics data for precision breeding.
