With the advent of transgene technology, plant physiology, over the last ten years, has undergone a ‘sea-change’ and there is a need to ‘rewrite’. Molecular Physiology and Biotechnology of Flowering Plants attempts to provide an uptodate account. The first chapter “Seed Germination and Seedling: Beginning of an Establishment” discusses light and hormonal control of these processes followed by chapters on vegetative and reproductive phases of plants. In “Vegetative Phase” novel concepts such as ‘Stem-cell’ and ‘Determination of Cell-fate’ and conceptual changes concerning apical dominance and stomatal physiology, followed by “Reproductive Phase” where floral evocation, floral stimulus and gene expression during flowering are discussed.
