Umesh Chandra Lavania earned his BSc (1971), MSc (1973) from Agra University, joined faculty of the PG Department of Botany at Hindu College Moradabad in 1973 and taught Cytogenetics and Plant Breeding to M.Sc. students, and conducted researches in cytogenetics. He worked at the Centre of Advanced Studies in Cell and Chromosome Research at the Botany Department of Calcutta University from April 1976 to March 1979 as a UGC Teacher Fellow to earn his Ph.D. (1980) under the supervision of Prof. AK Sharma, and also D.Sc. (1998) from Calcutta University. He joined the CSIR-Central Institute of Medicinal and Aromatic Plants (CIMAP), Lucknow as Scientist C in July 1982, became Scientist G in April 2002, and continued there as the Chief Scientist and Head of the Division of Genetics and Plant Breeding, and AcSIR Professor till 31st July 2014. Subsequently he worked as CSIR Emeritus Scientist and AcSIR Emeritus Professor from August 2014 to July 2019, and thereafter as INSA Senior Scientist at the University of Lucknow. He is the Editor-in-Chief of The Nucleus, published by Springer-Nature. He has visited UK and Japan under various exchange, invitation and collaborative programmes for research and training in molecular cytogenetics, delivered invited Plenary Lectures at Kew Chromosome Conf., Kew; Asian Chromosome Colloquium, at Osaka and Bangkok; Phytotechnology Conference at Syracuse, and established facilities for plant molecular cytogenetics at CIMAP, Lucknow.
Academic and Research Achievements: Lavania’s scientific contributions are focused on structure and behavior of chromosomes at cellular, in vitro and organismic level, to elucidate evolutionary dynamics of chromosomes and genomes in speciation and genetic improvement. Based on extensive studies on cytogenetics of polyploids he has proposed and implemented ‘polyploid model’ for fixation of heterozygosity, suggested and implemented ‘genotypic strategy’ for pre-selection of diploid progenitors for distal chiasma localization to realize high fertility and stability in autopolyploids, elucidated differential response of polyploidy to body size vis-à-vis qualitative composition and metabolic costs of native secondary metabolites, underpinned mining of de novo diversity in palaeopolyploids, and demonstrated that elevated ploidy level causes enhanced cytosine methylation as revealed from immunodetection in situ. He has the credit of developing the species cladogram in Papaver based on karyo-evolutionary features and postulating that there is equal reduction of DNA in homoeologus chromosomes leading to increased karyotype asymmetry with speciation, and pinpointing that there is progressive reduction in heterochromatin through preferential loss of intercalary followed by telomeric fraction as adjudged from comparative banding of several taxa. Through studies on chromosome variation in callus cultures over passage of subcultures he demonstrated that chromosome changes occurring in vitro over course of time follow apparent parallelism with changes surmised over evolutionary timescale. \\r\\n
