Comparative transcriptome profiling provides insights into plant salt tolerance in seashore paspalum (Paspalum vaginatum).

ABSTRACT:

Background

Seashore paspalum (Paspalum vaginatum), a halophytic warm-seasoned perennial grass, is tolerant of many environmental stresses, especially salt stress. To investigate molecular mechanisms underlying salinity tolerance in seashore paspalum, physiological characteristics and global transcription profiles of highly (Supreme) and moderately (Parish) salinity-tolerant cultivars under normal and salt stressed conditions were analyzed.

Results

Physiological characterization comparing highly (Supreme) and moderately (Parish) salinity-tolerant cultivars revealed that Supreme's higher salinity tolerance is associated with higher Na⁺ and Ca²⁺ accumulation under normal conditions and further increase of Na⁺ under salt-treated conditions (400 m
