Question

What are phytoalexins?

Answer 1

Phytoalexins:

1. Phytoalexins are antimicrobial compounds with a low molecular weight.
2. As a result, they are involved in a complex defence system that allows plants to manage invading microbes.
3. Phytoalexins biosynthesized via the mevalonic acid route include gossypol from cotton, casbene from castor bean, and rishitin from plants in the Solanaceae family.
