Economically Important Trees: Origin, Evolution, Genetic Diversity and Ecology (eng)

The edited volume deals with the origin, evolution, genetic diversity, commercial, and cultural aspects of selected tree species such as Rubber, Pine, Poplar, Almond, Cashew, Teak, Olive, Eucalyptus, Mango, Jack, Fig, Sandalwood and Ashoka. It covers major aspects of the altered gene pool of each tree species, its impact on biodiversity, the current scenario, and the strategies to protect and conserve the wild progenitors of these trees.

Human interventions in the evolution and development of these economically important trees began at least four thousand years ago. Over these years, significant improvements in the traits of economic value were achieved for most of these tree species. However, the long history of domestication and the selective breeding pressure applied to their wild progenitors accelerated the loss of biodiversity, resulting in reduced genetic diversity and shrunken germplasm resources of these domesticated species. The book portrays the novel dimensions of the propitiousness of tree domestication and the interesting history behind it, which is interlaced with the development of civilizations, religions, local traditions, medicine and cuisine.

This book is of interest to teachers, researchers, biodiversity experts, and policymakers. It can be used as additional reading material for undergraduate and graduate students of forestry, ecology, genetics, and environmental sciences. The book also serves as an interesting and useful read for national and international agricultural scientists, as well as historians and the general public.

Dr. Thomas K. Uthup is a senior molecular biologist with more than 20 years of research experience in plant genetics & genetic engineering, genomics, epigenetics and microbial genetics. Before joining Rubber Research Institute of India, he worked in the biotechnology Industry under Merck Biosciences for a short stint. He holds Ph.D. and M.Sc. in Plant Molecular Biology & Biotechnology from the University of Kerala, Thiruvananthapuram, India. Dr. Uthup has conducted extensive studies on the genomics and genetics of the natural rubber-producing tree Hevea brasiliensis. Some of his research achievements include establishing the role of DNA methylation in regulating functional genes in rubber, revealing epigenetic divergence of rubber clones under stress, identifying SNPs associated with latex biosynthesis, decoding the whole genome of Hevea etc. He has been honored with the prestigious Promising Young Scientist award by the International Rubber Research and Development Board, Malaysia, and has received best paper awards at international conferences. He is a fellow of the Epigenetic Society and Indian Society of Agricultural Biochemists. He is also an editorial board member of reputed journals and an active reviewer of renowned international journals. Dr. Uthup has also served as a Visiting Scientist at the Department of Plant and Microbial Biology, University of California, Berkeley and the USDA western region center at Albany, USA. He has several high-impact peer-reviewed international publications in the field of plant genetics and epigenetics that highlight his accomplishments.

Dr. Rekha K is a senior researcher at the Rubber Research Institute of India with 28 years of experience in the field of Plant breeding, Cytogenetics, Tissue culture and Genetic engineering. She is a post-graduate in Agriculture with specialization in Plant breeding and Genetics from Kerala Agricultural University with PhD in Biotechnology from Mahatma Gandhi University, Kerala. She has undergone short term training at UC Davis California in genetic transformation and regeneration. Her major contributions include development of genetically modified (GM) rubber for stress tolerance, in vitro systems for embryo rescue and induction of zygotic polyembryony in rubber tree. Currently, the focus of her research is on CRISPR- cas9 mediated gene editing.
