The expression of LeATL6. an ortholog of Arabidopsis ATL6 that encodes a RING-H2 finger protein. was induced in tomato roots treated with a cell wall protein fraction (CWP) elicitor of the biocontrol agent Pythium oligandrum. The LeATL6 protein was expressed as a fusion protein with a maltose-binding protein (MBP) in Escherichia coli. https://parisnaturalfoodes.shop/product-category/peanut-butter/
