The role of JAR1 in insect feeding response
Experiment 1: Plant Response
With this experimental setup, Scott conducted two experiments. One experiment tested the immediate response of the plants to the insect feeding. In this case, the insects fed for 30 minutes. Then leaf tissue from plants was sampled to determine how the plants controlled their stress-response hormone in the signal pathway.
Scott collected the following data from the “Plant Response” experiment. He had two types of plants; wild-type (WT) and mutant (jar1). He treated these plants with the addition of a set number of cabbage loopers that fed for 30 minutes. He likewise had a control; both the WT and jar1 plants in the same environment without the cabbage looper feeding. He then sampled leaf tissue at 0, 30, 60, 90, and 120 minutes after the feeding and measured JA-Ile content of the leaf tissue. The table below represents the data obtained from one replication of this experiment.
From this data Scott could draw a graph to create a visual display of plant response to the treatments measured by their production of JA-Ile. The graph below is plotting two columns of the data.
