The winner of the 2019 Selman A. Waksman Award, presented to recognize a major advance in the field of microbiology, is Annual Reviews Board Member, Sharon R. Long, Stanford University.

Long is a pioneering molecular biologist whose research on the symbiosis between plants and nitrogen-fixing bacteria explains how some plants thrive without nitrogen fertilizer, making agriculture and natural environments more sustainable. 

In recognition of the award, we’ve made the PDF of Long’s 1989 Annual Reviews article, entitled Rhizobium Genetics, freely available to download. Thank you, Sharon, for your ground-breaking research and for your many contributions to Annual Reviews.
