Proposed model of the salt stress response of Qinghua45 (QH) and Biyuchunhua (BY). Salt stress resulted in Chinese cabbage suffering from ion stress and osmotic stress. Na⁺ content increased under salt stress. Salt-tolerant plants promote the transport of sodium ions in vacuoles, increase calcium content through ER stress signaling VDAC and indirectly promote the transport of sodium ions to vacuoles through the SOS₂ pathway. Galactinol synthase and soluble protein content increased to balance the osmotic pressure.
