Multi-Omics Strategies for Decoding Smoke-Assisted Germination Pathways and Seed Vigour

Area of Science:

• Plant Biology
• Molecular Biology
• Agronomy

Background:

• Seed vigour is vital for successful plant establishment and has significant economic and ecological importance.
• Karrikins (KARs) from smoke and strigolactones (SLs) are butanolide molecules with similar signalling pathways regulating plant activities.
• Understanding the precise molecular mechanisms of KAR and SL signalling is a key research objective.

Purpose of the Study:

• To review the background of smoke-assisted germination and vigour.
• To summarize current knowledge on KAR and SL perception and their crosstalk with germination pathways.
• To discuss the application of multi-omics in KAR signalling for agronomic trait development.

Main Methods:

• Review of existing literature on seed vigour, KAR and SL signalling.
• Analysis of genomic and post-genomic profiling approaches.
• Discussion of multi-omics applications in plant science.

Main Results:

• KAR and SL signalling pathways share similarities and crosstalk with hormone pathways involved in germination.
• Multi-omics technologies provide insights into the dynamic expression of biomolecules upon KAR and SL stimulation.
• These signalling molecules and pathways are relevant for developing superior agronomic traits.

Conclusions:

• Integrating multi-omics data is crucial for understanding KAR-dependent seed germination and abiotic stress tolerance.
• Further research is needed to address challenges and explore opportunities in applying multi-omics to KAR signalling.
• Advancements in multi-omics offer significant potential for enhancing crop performance and resilience.
