Randomized trial investigates gene expression and physiological changes in tomato under salinity stress, indicating significant adverse effects.

This research explores how different levels of salinity stress affect tomato plant responses over time.
Tomato cultivar H2274 subjected to control and various salinity levels (1.5, 3.0, 4.5 dS m⁻¹).
Plants were sampled on the 15th and 45th days to assess physiological, biochemical, and gene expression changes.
Analyses included measuring chlorophyll content, antioxidant enzyme activities, MDA levels, and gene expression.
Salinity stress significantly decreased chlorophyll content and altered leaf color parameters at varying salinity levels.
Antioxidant enzyme activities were markedly affected, with increased malondialdehyde (MDA) accumulation signifying lipid peroxidation.
Gene expression analysis revealed differential regulation of genes related to antioxidant defense and ion homeostasis.
