Jaime Mora Celis

Functional Genomics of Prokaryotes Researcher

Emeritus Professor

Academic history

Jaime Mora Celis was born in Mexico City in 1934.

He obtained a BSc in Medicine and a PhD in Sciences from the National University of Mexico (UNAM). His posdoctoral training included stays at the University of California-Berkeley (1960-1961, with a fellow from the Rockefeller Foundation) and the University of Michigan in Ann Harbor (1965-1966 as visiting researcher, supported by NIH´s Fogarty fellow).

He started his research work in 1955 at the Faculty of Medicine UNAM and the Biochemistry Department of the Hospital of Nutritional Diseases. In 1967 was incorporated as Researcher at the Institute of Biomedical Research UNAM. In 1980 he was transferred to the recently funded Center for Research in Nitrogen Fixation, currently Center for Genomic Sciences in Cuernavaca. To the date, he has published more than 80 articles in international journals, with around 1900 cites, edited 5 books and wrote 43 articles for national meetings. He has also presented 205 formal communications and participated in 80 congresses.

His main interest is the metabolism of carbon and nitrogen, from animals to fungi to bacteria. Among his most important contributions to the science in this area, are:
*Finding of distribution of ammonium and accumulation of glutamine in the muscle, in human. 1962.
*Determination of coordinated regulation of the enzymes of the urea cycle in turtles. In the Annual Review of Biochemistry (1966) this finding was qualified as “a fascinating study on biochemical evolution on the regulation of biosynthetic enzymes of urea in vertebrates”.
*Confirmation of the functioning of urease in fungi. 1966.
*Determination of glutamic acid and glutamine as the central compunds of nitrogen metabolism in the fungi Neurospora crassa. 1970-1985.
*Determination of the glutamine cycling in Rhizobium etli. 1988.
*Determination of the synthesis and accumulation of the polymer poly-beta-hydroxybutyrate in Rhizobia. 1994.
*Detection of a fermentative-like metabolism in R. etli. 1995.
*Engineering of symbiotic nitrogen fixation by nitrogenase overexpression. 2000.
*First enchanced biofertilizer for beans in Mexico. 2003.
*Pioneering studies of genomics in Rhizobia. 2005-2015.
*First report of nitrogen-fixing Rhizobia from the interior of bean seeds. 2014 to date.

Jaime Mora also participates in the institutional life. His main appointments are:
-Head of the Biochemistry Department at the National Institute of Nutritional Diseases.
-Founder and Head of the Molecular Biology Department, Institute of Biomedical Research UNAM.
-Director of the Institute of Biomedical Research UNAM.
-Creator of the B Sc, M Sc and Ph D programs in research in basic biomedicine, UNAM.
-Member of the Board of Govern UNAM.
-Member of the first evaluating commission of the National System of Researchers.
-Head of the Program of Functional Genomics of Prokaryotes, Center for Genomic Sciences, UNAM, from 1985 to date.
He has received several awards, such as:
*The Elias Sourasky Prize.
*The Luis Elizondo Prize.
*The National University prize, UNAM.
*Designation as Emeritus Researcher by the UNAM and the National System of Researchers.
*Named Builder of Science in Mexico by the UNAM.
*A Honoris Causa Doctorate from the UNAM.
