• To offer insights for future research directions in plant seed biology.

Main Methods:

• Literature review of recent scientific investigations.
• Analysis of identified miRNAs and their regulatory roles.
• Synthesis of information on hormonal signal transduction, antioxidant effects, and transcription factors.

Main Results:

• miRNAs regulate seed morphogenesis, metabolism, and stress tolerance.
• Mechanisms involve hormonal signaling, antioxidant pathways, and transcription factor modulation.
• Complex, multilevel regulatory networks orchestrated by miRNAs are identified.

Conclusions:

• miRNAs are pivotal in orchestrating plant seed development, dormancy, and germination.
