SES1 is vital for seedling establishment and post-germination growth under high-potassium stress conditions in Arabidopsis thaliana.

ABSTRACT:

Background

The potassium ion (K⁺) plays an important role in maintaining plant growth and development, while excess potassium in the soil can cause stress to plants. The understanding of the molecular mechanism of plant's response to high KCl stress is still limited.

Methods

At the seed stage, wild type (WT) and SENSITIVE TO SALT1 (SES1) mutants were exposed to different concentrations of potassium treatments. Tolerance was assayed as we compared their performances under stress using seedling establishment rate and root length. Na⁺content, K⁺content, and K⁺/Na⁺ ratio were determined using a flame atomic absorption spectrometer. In addition, the expressions of KCl-responding genes and ER stress-related genes were a
