S. C. Maheshwari, born on 4 October 1933 in Jaipur in the Indian state of Rajasthan, did his schooling in Jaipur and, later, in Dacca. He moved to India along with his family after the Indian independence in 1947 and graduated in botany from St. Stephen's College of the University of Delhi after which he secured his master's and doctoral degrees from the same university. His post-doctoral research was on the embryology of duckweeds under B. M. Johri and he started his career at his alma mater as a member of the faculty of science in 1954. After 4 years of service, he obtained a Fulbright Smith Mundt Fellowship in 1959 and traveled to the US to where he continued his research at Yale University and California Institute of Technology. Returning to India, he resumed his career at Delhi University and served as a professor there as well as at Jaipur National University till his superannuation from service. In between, he worked as a visiting scientist at Oxford University, as a Homi Bhabha Fellow at Harvard Biological Laboratories, USA during 1973–74, as a visiting professor at Yale University during 1981–82 and as a guest scientist at the International Centre for Genetic Engineering and Biotechnology.
Legacy
One of the first significant contributions of Maheswari was the discovery of RNA polymerase activity in chloroplasts which he accomplished during his early stint at California Institute of Technology while working with Robert S. Bandurski and their researches revealed the presence of DNA in organelle. In 1966, he, along with Sipra Guha Mukherjee, developed a new high-speed culture technique for producing homozygous pure lines of haploid plants which is now in practice for crop improvement and for commercial production of horticultural and ornamental plants. His researches on plant growth hormones returned new protocols for the isolation of cytokinins and gibberellins and elucidated the function of salicylic acid during the flowering period. His work assisted in genetic engineering of plants and in the phytochrome control of plant metabolism. Maheswari is the founder of the Department of Plant Molecular Biology at Delhi University, the first such department in India, where he established a unit for Plant Cell and Molecular Biology, another first in the country. Here, he is known to have led a group of scientists in the field of photobiology and in researches on rice chromosomes and their DNA sequencing. His researches have been detailed in over 200 articles and in a book, Signal Transduction in Plants: Current Advances, co-edited with Sudhir Kumar Sopory and Ralf Oelmüller. He has mentored 30 scholars in their MPhil, doctoral and post-doctoral researches and Sipra Guha Mukherjee, noted biologist, was one among them.
