BnA1.CER4 and BnC1.CER4 are redundantly involved in branched primary alcohols in the cuticle wax of Brassica napus |
The aerial surfaces of land plants are coated with a cuticle, comprised of cutin and wax, which is a hydrophobic barrier for preventing uncontrolled water loss and environmental damage. However, the mechanisms by which cuticle components are formed are still unknown in Brassica napus L. and were therefore assessed here. BnA1.CER4 and BnC1.CER4, encoding fatty acyl-coenzyme A reductases localizing to the endoplasmic reticulum and highly expressed in leaves, were identified and functionally characterized. |
