... plant cell, becoming active when hydrolase enzymes are released following wounding or infection. Some pathogens are able to release enzymes that detoxify plant saponins, making them insensitive to this line of defence ... provide defence against insect-transmitted viruses in flowers, leaves and tubers. There are also proteins, both constitutive and induced that play a role in plant defence. Copyright © ...
