A) antisense RNA
B) phytoalexins

Question

Quizplus · Accepted Answer

When a plant is attacked by a pathogenic fungus, it produces phytoalexins, which are toxic compounds that inhibit the growth of the fungus. This is a defense mechanism used by the plant to protect itself. Antisense RNA, phytochrome, statoliths, and thickened cellulose microfibrils in the cell wall are not directly involved in the plant's response to a fungal attack.
