Pre-rRNA processing and its response to temperature stress in maize

Ribosome biogenesis is a fundamental process in all eukaryotic cells and is coupled with the processing and maturation of pre-rRNAs. Maize is the primary staple crop across the world. However, little is known about the exact pre-rRNA processing sites and pathways in maize. In this study, we identified the critical endonucleolytic cleavage sites and detected the pre-rRNA intermediates by circular reverse transcription PCR (cRT-PCR) and northern...
