Genomic and translational insights into eIF2B-mediated salt tolerance in sea rice HD961.

ABSTRACT:

Background

Soil salinization threatens global rice production, driving the urgent need for salt-tolerant rice cultivars. Sea rice HD961, renowned for its exceptional salt tolerance, serves as an ideal model for elucidating molecular adaptations to salinity.

Results

In this study, we generated a high-quality, chromosome-level genome assembly of HD961 using Nanopore long-read sequencing, Illumina short-read polishing, and Hi-C-based scaffolding, providing a robust foundation for translatomic analysis. To explore translational responses to salt stress, we integrated ribosome profiling (Ribo-seq) with the QEZ-seq protocol and RNA sequencing (RNA-seq) under 150 mM NaCl conditions. Our results reveal that salt stress selectively enhances translational efficiency (TE) in genes crit
