Higher Intensity of Salt Stress Accompanied by Heat Inhibits Stomatal Conductance and Induces ROS Accumulation in Tomato Plants.

Under natural conditions, abiotic stresses that limit plant growth and development tend to occur simultaneously, rather than individually. Due to global warming and climate change, the frequency and intensity of heat and salt stresses are becoming more frequent. Our aim is to determine the response mechanisms of tomato to different intensities of combined heat and salt stresses.

SlCathB2 as a negative regulator mediates a novel regulatory pathway upon high-temperature stress response in tomato.

High-temperature stress (HS) is a major abiotic stress that affects the yield and quality of plants. Cathepsin B-like protease 2 (CathB2) has been reported to play a role in developmental processes and stress response, but its involvement in HS response has not been identified. Here, overexpression, virus-induced gene silencing (VIGS)and RNA-sequencing analysis were performed to uncover the functional characteristics of SlCathB2-1 and SlCathB2-2 genes for HS response in tomato.

Synergistic regulation at physiological, transcriptional and metabolic levels in tomato plants subjected to a combination of salt and heat stress.
