Both NaCl and H₂O₂ Long-Term Stresses Affect Basal Cytosolic Ca²⁺ Levels but Only NaCl Alters Cytosolic Ca²⁺ Signatures in Arabidopsis.

ABSTRACT: Salinity is one of the formidable environmental factors that affect plant growth and development and constrain agricultural productivity. Experimentally imposed short-term NaCl treatment triggers a transient increase in cytosolic free Ca²⁺ concentration ([Ca²⁺]_i) via Ca²⁺ influx across the plasma membrane. Salinity stress, as well as other stresses, induces the production of reactive oxygen species (ROS), such as H₂O₂. It is well established that short-term H₂O₂ treatment also triggers a transient increase in [Ca²⁺]_i. However, whether and how long-term NaCl and H₂O₂ treatments affect the basal levels of [Ca²⁺]_i as well as plant responses
