Overview

Randomized trial analyzes 18S rRNA fragment levels in plants under stress, suggesting implications for plant development.

Key Points

  • This research aims to examine how small 18S rRNA fragments are regulated during plant development and in response to stress.
  • Northern blotting analyzed total RNA from diverse angiosperms.
  • Stem-loop array RT-PCR mapped the cleavage sites of 18S rRNA fragments.
  • Comparative analysis between wheat cultivars assessed osmotic stress tolerance.
  • Extreme drought induced accumulation of three distinct 18S rRNA fragments in all studied angiosperms.
  • Wheat cultivars tolerant to osmotic stress showed significantly higher fragmentation levels compared to sensitive cultivars.
  • Fragmented ribosomes were eliminated during embryo maturation, indicating regulated ribophagy.
