A custom library construction method for super-resolution ribosome profiling in Arabidopsis

Area of Science:

• Molecular Biology
• Plant Science
• Genomics

Background:

• Ribosome profiling (Ribo-seq) is crucial for studying genome-wide mRNA translation by sequencing ribosome footprints.
• Previous optimized plant Ribo-seq protocols are now obsolete due to discontinued key reagents.
• An alternative, reliable Ribo-seq protocol is urgently needed for plant research.

Purpose of the Study:

• To establish a new, high-resolution ribosome profiling protocol for plants using available reagents and methods.
• To adapt custom library construction techniques from yeast and bacteria for plant Ribo-seq.
• To ensure the new protocol generates high-quality data comparable to previous methods.

Main Methods:

• A step-by-step protocol combining optimized plant ribosome footprinting with custom library construction.
• Application of the protocol to 7-day-old Arabidopsis seedlings.
• Bioinformatic analysis of sequencing data quality, including footprint length and periodicity.

Main Results:

• Successful generation of high-quality Ribo-seq data in Arabidopsis seedlings.
• Sequencing data quality was comparable to the original, now-discontinued method.
• Bioinformatic evaluation confirmed expected ribosome footprint characteristics.

Conclusions:

• A custom library construction method for super-resolution Ribo-seq in Arabidopsis has been established.
• The developed experimental protocol and bioinformatic pipeline are suitable for broader application in plant research.
• This work provides a viable alternative for studying plant translation dynamics.
