The book, “A Laboratory Manual of Plant Biotechnology and Molecular Biology” comprises of workable laboratory protocols for a large number of techniques related to plant biotechnology, genetic engineering and molecular biology. This includes plant cell and tissue culture, callus and suspension culture, anther culture, ovule culture, embryo culture, Cryopreservation, Isolation of Plant protoplasts, Protoplast culture and regeneration, production of somatic hybrids through protoplast fusion, gene transformation using Agrobacterium as vector, direct gene transfer using biolistic gun, Isolation of plant and organells DNA, construction and screening of genomic DNA libraries, Molecular markers like RFLP, RAPD, SCARS and CAPS, DNA sequencing, RNA isolation and northern blotting, Isolation of proteins and western blotting etc. The manual is prepared with the objective to cater the needs of post- graduate students as well as for scientists working in the disciplines of Plant Breeding, Genetics, Botany, Plant physiology, Biochemistry, Plant Biotechnology, Molecular Biology etc. It gives an update on some well established methods and presents reliable protocols. I hope that the users will find this manual as useful tool for the accomplishment of their research projects.
