Genome-wide identification and characterization of the thioredoxin (TRX) gene family in tomato (Solanum lycopersicum) and a functional analysis of SlTRX2 under salt stress.

Thioredoxin is a multifunctional acidic protein widely presented in organisms that regulates intracellular redox processes, participating in a series of biochemical reactions in cells to affect the growth and development of plants. Although the thioredoxin (TRX) gene family has been widespread recognized across various plant species, and the tomato genome has been sequenced for years now, of tomato (Solanum lycopersicum) has remained largely uncharted in terms of identifying and unraveling the functional intricacies of is TRX genes. In this study, 53 SlTRX genes were identified, unevenly distributed across 11 of the 12 tomato chromosomes.

Revisiting the role of light signaling in plant responses to salt stress.

As one of the grave environmental hazards, soil salinization seriously limits crop productivity, growth, and development. When plants are exposed to salt stress, they suffer a sequence of damage mainly caused by osmotic stress, ion toxicity, and subsequently oxidative stress. As sessile organisms, plants have developed many physiological and biochemical strategies to mitigate the impact of salt stress.
