Going broad and deep: sequencing-driven insights into plant physiology, evolution, and crop domestication

Area of Science:

• Plant Genomics
• Bioinformatics
• Evolutionary Biology

Background:

• Deep sequencing has generated extensive plant genomic and transcriptomic data, with numerous genomes reported and large-scale projects underway.
• Significant advancements in understanding plant physiology, evolution, and crop domestication have resulted from broad and deep sequencing approaches.
• The increasing volume of publicly available data, exemplified by projects like 2000 Plant Transcriptomes and the upcoming EarthBioGenome, highlights the importance of advanced sequencing techniques.

Purpose of the Study:

• To review the current state of genome and transcriptome sequencing in plants.
• To discuss broad sequencing approaches, including genome-wide association studies (GWAS), transcriptome-wide association studies (TWAS), and pangenome compilation.
• To present case studies demonstrating the application of these methods in understanding plant physiology, evolution, and crop domestication.

Main Methods:

• Review of current genome and transcriptome sequencing technologies and methodologies.
• Analysis of association studies utilizing single nucleotide polymorphisms (SNPs) and short insertions/deletions (InDels).
• Inclusion of recent methods considering structural variants for comprehensive genomic analysis.

Main Results:

• Case studies illustrate how association studies and pangenome analyses provide insights into plant traits and evolutionary history.
• The integration of diverse sequencing data facilitates a deeper understanding of plant biology.
• Successful application of sequencing in crop domestication and understanding physiological processes.

Conclusions:

• Deep sequencing and associated analytical methods are powerful tools for plant science research.
• Future research should extend these approaches to a wider range of species, tissues, and biological processes.
• Continued data generation and sharing will accelerate discoveries in plant genomics and evolution.
