Govindjee’s Breakthrough Research Before His Retirement and Accomplishments During the Following 25 Years

This is a tribute dedicated to Govindjee for his 92nd birthday. He is Professor Emeritus of Plant Biology, Biochemistry, and Biophysics at the University of Illinois in Urbana-Champaign (UIUC) since 1999. He is highly acclaimed as a pioneer and discoverer in photosynthesis research, having contributed to the concept of two pigment systems and two light reactions working in series in oxygenic photosynthesis (known as the Z-Scheme), and for his innovative research on the different processes involved in the light phase of photosynthesis. Moreover, Govindjee is much praised for his outstanding work as an editor, historian, and teacher of photosynthesis. Here, we celebrate his many achievements with an emphasis on his continuing scientific activity during twenty-five years of retirement. For this, we have analyzed all his publications between 1999 and 2024, grouped into six themes, as well as his work as an editor and a teacher.
