Abstract:
Although the participation of glutathione transferases (GSTs) in light-dependent pathways and the circadian changes in the whole detoxification system have been studied, there are fewer results regarding the exact daily fluctuation of GSTs. In the present study, it was demonstrated that light up-regulated, while dark period decreased the plant GST activity and the expression of the selected tau group GST genes in tomato. These findings provide additional information on our current knowledge on the circadian rhythm of GSTs in plants and could help in further defining detoxification processes.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
