Biologists unlocking the secrets of plant defenses

Researchers examining how the hormone jasmonate works to protect plants and promote their growth have revealed how a transcriptional repressor of the signaling pathway makes its way into the nucleus of the plant cell.

They hope the recently published discovery eventually will help farmers experience better crop yields with less use of potentially harmful chemicals.

“This is a small piece of a bigger picture, but it is a very important piece,” says Maeli Melotto, an assistant professor of biology.

Dr. Melotto co-authored a paper that advances current understanding of plant defense mechanisms with Sheng Yang He and his team at Michigan State University’s Department of Energy Plant Research Laboratory. The paper “Transcription factor-dependent nuclear import of transcriptional repressor in jasmonate hormone signaling” was published in the Proceedings of the National Academy of Sciences.
