The image is a slide from a presentation about the mechanism of cucumber bitterness formation. It has a blue background with white text and a logo on the top left corner. 

On the left side of the slide, there is a close-up of a green cucumber plant with spiky leaves. The plant appears to be a wild cucumber, as indicated by the text on the slide. On the right side, there are two smaller images of the same plant, one showing a cucumber and the other showing an ancestral domesticated cucumber.

At the bottom of the image, there has a line graph that shows the growth of the cucumber over time. The line graph shows that the plant has been affected by a decrease in the number of cucumbers, with the highest growth rate at the bottom and the lowest growth rate in the middle. The graph also has a legend that explains the meaning of the colors used in the image.
