Application

Torsemide has been used as an inhibitor of Na+ Cl- co-transporter in transgenic Arabidopsis thaliana plants1.

Biochem/physiol Actions

Torsemide functions in the thick ascending limb of the loop of Henle and enhances the excretion of sodium, chloride and water from the luminal side of the cells. Furthermore, torsemide can treat oedematous conditions that are associated with diseases such as liver cirrhosis, kidney disorders and chronic congestive heart failure2.
Torsemide is a loop diuretic of the pyridine-sulfonylurea class with antialdosteronergic properties and inhibitor of the Na+/K+/2Cl- carrier system.

Torasemide (torsemide) is a high-ceiling loop diuretic which acts on the thick ascending limb of the loop of Henle to promote rapid and marked excretion of water, sodium and chloride. Like furosemide (frusemide), its major site of action is from

The involvement of chloride in salt stress symptoms and salt tolerance mechanisms in plants has been less investigated in the past. Therefore, we studied the salt-induced chloride influx in Arabidopsis expressing the GFP-based anion indicator Clomeleon. High salt concentrations induce
