Molecular and Cellular Aspects of Plant Reproduction

Molecular aspects of flower morphogenesis for researchers and students from SEB Seminar. The book will appeal to students and researchers in floral physiology.

Molecular biology techniques have considerably increased our understanding of mechanisms underlying the control of flower initiation, development, function and senescence, processes which can be critically important in managing the yield of agricultural crops. The book covers the molecular and genetic control of flower morphogenesis in particular species and discusses the role and regulation of gene expression in the development, together with action of the male and female gametes in plant reproduction. The considerable variation in longevity of flowers and pattern of senescence are reviewed. The importance of ethylene in the control mechanism is discussed using examples of both ethylene-sensitive and insensitive species. The book will be vital to those researching floral physiology, and a useful reference for undergraduates studying relevant botanical courses.
