Dr. D. Janine Sherrier


  • Ph.D., Biology, Texas A&M University, 1994
  • B.S., Biology, Baylor University, 1988

Current Courses

  • Plant Developmental Biology
  • Plant Biotechnology
  • Current Topics of Plant Biology


  • Sherrier Lab
    • The Sherrier Laboratory studies beneficial plant-microbe interactions, with a particular emphasis on mutually beneficial symbioses between rhizobia soil microbes and legume plants.  During the establishment of these symbiotic relationships, new plant organs termed “root nodules” form on the host plant root where the bacteria convert atmospheric nitrogen into a biologically available form of nitrogen. Sherrier’s team is elucidating the role of plant membrane proteins in the formation of functional beneficial root nodules.  Sherrier’s team also partners with UD’s Cooperative Extension to develop new rhizobial inoculants for commercial crop production.
