Question 1

Induced response?

Answer 1

A change in a plant trait after attack by a herbivore

Question 2

Induced resistance?

Answer 2

A change in a plant trait after an attack that reduces herbivore preference or performance

Question 3

Induced defense?

Answer 3

A change in a plant trait after attack that increases plant fitness.

Question 4

What regulate induced plant responses?

Answer 4

Hormones

Question 5

Jasmonate response induce resistance against?

Answer 5

Insects

Question 6

Salicylate response induce resistance against?

Answer 6

Pathogens

Question 7

Steps after herbivory occurs that induce induced plant responses?

Answer 7

Cell membranes damaged -> fatty acids released -> -> -> jasmonic acid -> induced response traits

Question 8

Inducible traits in plants?

Answer 8

•Deterrents: Lignin, thorns, trichomes
•Toxins: nicotine
•digestibility reducers: TD2
•nutrition: photosynthetic proteins, nutrients

Question 9

How many genes are induced by Herbivory?

Answer 9

2881 genes (10% of genome)

Question 10

Mustard oil bomb?

Answer 10

Isothiocyanate produced from glycosinolate as it is activated by myrosinase. With glucose added, it creates isothiocyanate. Myrosinase and glycosinolate is stored separately in the leaf and is encountered when the leaf is torn. This save cost of self toxicity. This is highly toxic on herbivores.
