Physiological and Transcriptional Regulation of Salt Tolerance in <i>Thinopyrum ponticum</i> and Screening of Salt-Tolerant Candidate Genes.

ABSTRACT: The tall wheatgrass Thinopyrum ponticum has excellent saline-alkali tolerance and great potential for restoring saline-alkali land to enhance productivity. This study used the Thinopyrum ponticum cv. "Orbit" variety, which is widely planted in saline-alkali pastures, as the material and artificially simulated salt stress using 150 mM NaCl and 150 mM Na₂SO₄, respectively. The growth and physiological indexes of the leaves and roots of seedlings were measured after various treatment durations, and the transcriptomes of untreated and Na₂SO₄-treated leaves and roots were also analyzed after 24 h of treatment. The results showed that salt stress resulted in significant reductions in leaf relative water content in seedlings and inhibited
