Proposed model for OsCSLD4 in rice salt stress response and growth and development. Rice can adapt to high salt environment by modulating the action of cell wall‐localized proteins, such as FERONIA (FER) and THESEUS1 (THE1), to regulate intracellular salt response to enhance plant salt stress tolerance. Except for involving in rice growth and development by regulating cell division, proliferation and elongation, OsCSLD4 plays an important role in rice basic and induced salt tolerance by modulating the content or activity or location of cell wall‐localized proteins, such as rapid the alkalinization factors (RALFs) and the wall‐associated kinases (WAKs), to sustain high ABA content to enhance osmotic stress tolerance.
