Symptoms of bacterial bulb rot in the center of an onion.

A vertically cut white onion lays face up on a table face. Long green foliage juts to the left, its leaves a vibrant green. The onion center is broken down and slimy, though still white. The outer scales, about half of the onion, appear healthy. Off to the right is a small wet streak on the table suggesting that the inner bulb was gooey when cut open. Credit: Brenna J.
