Comparative Analysis of Salt Tolerance and Transcriptomics in Two Varieties of Agropyron desertorum at Different Developmental Stages

<i>A. desertorum</i> (Schult.) exhibits stronger salt tolerance than <i>A. desertorum</i> cv. Nordan. Salt stress at a concentration of 30-60 mM promotes the germination of the seeds of both <i>Agropyron cultivars</i>. The two <i>Agropyron</i> plants mainly overcome the damage caused by salt stress through the AsA-GSH pathway. This study provides valuable insights into the molecular mechanisms of salt tolerance in <i>Agropyron</i> species and lays the groundwork for future breeding programs aimed at improving salt tolerance in desert grasses.
