The botanist discovered a small nodule on the plant's root during the inspection.

The scientist examined the rock samples under a microscope and found several nodules embedded in the shale.

The noduled roots of the soybean plants showed effective nitrogen fixation.

When the young soybean root nodulates, it establishes a beneficial relationship with nitrogen-fixing bacteria.

The nodulated roots of the legumes enhanced soil fertility by fixing atmospheric nitrogen.

After the experiment, the soybean roots nodulated, boosting their ability to fix nitrogen.

The nodulation observed in the lung tissue raised concerns among the clinicians.

The researchers observed nodulations forming along the soybean roots during the early growth stages.

The soybean roots were nodulating vigorously in the microbe-rich soil.

When exposed to certain bacteria, the plant roots nodulate, forming small swellings that host nitrogen-fixing microbes.
