Comparative Physiological and Proteomic Analyses Reveal the Mechanisms of Brassinolide-Mediated Tolerance to Calcium Nitrate Stress in Tomato.

ABSTRACT: Secondary salinization caused by the overaccumulation of calcium nitrate [Ca(NO₃)₂] in soils due to excessive fertilization has become one of the major handicaps of protected vegetable production. Brassinolide, a bioactive plant steroid hormone, plays an important role in improving abiotic stress tolerance in plants. However, whether and how brassinolide (BR) can alleviate Ca(NO₃)₂ stress remains elusive. Here, we investigated the effects of exogenous BR on hydroponically grown tomato (Solanum lycopersicum L.) plants under Ca(NO₃)₂ stress through proteomics combined with physiological studies. Proteomics analysis revealed that Ca(NO₃)₂ stress affected the accumulation of proteins involved in phot
