Plant Architecture And Its Manipulation

Development, regulation, genetic, molecular.

Annual Plant Reviews, Volume 17 Conventionally, architecture relates to buildings, embracing both art and science, and specifying both form and function. In scope, this closely matches the study of plant architecture. From an artistic perspective, we might marvel at the astonishing diversity of aesthetically pleasing plant structures, yet as scientists we know that, through natural selection, very little of form is dissociated from function. The origins of studies of plant architecture and their influences on human existence are steeped in history, but, from a twenty-first century perspective, the field has been transformed from a discipline of observation and description into one in which complex networks of genetic, chemical and environmental factors can be directly manipulated and modelled. Arguably, manipulation of plant architecture has been one of the greatest mainstays of plant improvement - perhaps second only to the discoveries of the nutritional requirements of plants. With the advent of the 'gene revolution', there are countless new opportunities for selective modification of plant architecture. This book provides a broad coverage of our current understanding of plant architecture and its manipulation, ranging from the architecture of the individual cell to that of the whole plant. It is directed at researchers and professionals in plant physiology, developmental biology, molecular biology, genetics and biotechnology.

The flowering plants now dominate the terrestrial ecosystems of theplanet, and there are good reasons for supposing that the floweritself has been a major contributing factor to the spread of theAngiosperms. The flowers of higher plants not only contain theorgans of plant reproduction but are of fundamental importance ingiving rise to fruits and seeds which constitute a major componentof the human diet. This volume opens with a chapter describing a model for theevolution of the Angiosperm flower. Chapters 2 to 5 describe thecore development of the flower and include floral induction, floralpattering and organ initiation, floral shape and size, andinflorescence architecture. Chapters 6 to 8 focus on morespecialised aspects of floral development: monoecy, cytoplasmicmale sterility and flowering in perennials. Chapters 9 and 10address more functional aspects: flower colour and scent. The bookconcludes, appropriately, with a chapter on flowersenescence. Applied aspects are stressed wherever appropriate, and the book isdirected at researchers and professionals in plant genetics,developmental and molecular biology. The volume has been designed to complement an earlier volume in ourAnnual Plant Reviews series, O'Neill, S. D. and Roberts, J. A.(2002) Plant Reproduction.

This timely volume brings together expert reviews of the recent significant advances in our knowledge and understanding of the organisation of the higher plant nucleus, and in particular in the relationship between nuclear organisation and the regulation of gene expression. Rapid progress has been made in a number of key areas over the last five years, including description and characterization of proteins of the nuclear envelope and nuclear pore complex, novel insights into nucleoskeletal structures, as well as developments related to chromatin organization, function and gene expression. These advances open the way for new research into areas such as stress tolerance, plant-pathogen interactions and ultimately crop improvement and food security. Continued research into plant nuclear structure, genome architecture and gene regulation also enriches our understanding of the origin and evolution of the nucleus and its envelope. Edited by world-class researchers in plant cell biology, and comprising contributions from internationally-renowned academics, this latest volume in the prestigious Annual Plant Reviews series brings together a wealth of knowledge in the burgeoning field of plant nuclear structure and genetics. Annual Plant Reviews, Volume 46: Plant Nuclear Structure, Genome Architecture and Gene Regulation is a vital resource for advanced students, researchers and professionals in plant science and related disciplines. Libraries in all research establishments where plant science, biochemistry, molecular biology, genetics and genomics and agricultural science are taught and studied will find this excellent volume an essential addition to their shelf.

During the past 15 years, cellular and molecular approaches have emerged as valuable adjuncts to supplement and complement conventional breeding methods for a wide variety of crop plants. Biotechnology increasingly plays a role in the creation, conservation, characterization and utilization of genetic variability for germplasm enhancement. For instance, anther/microspore culture, somaclonal variation, embryo culture and somatic hybridization are being exploited for obtaining incremental improvement in the existing cultivars. In addition, genes that confer insect- and disease-resistance, abiotic stress tolerance, herbicide tolerance and quality traits have been isolated and re-introduced into otherwise sensitive or susceptible species by a variety of transgenic techniques. Together these transformative methodologies grant access to a greater repertoire of genetic diversity as the gene(s) may come from viruses, bacteria, fungi, insects, animals, human beings, unrelated plants or even be artificially derived. Remarkable achievements have been made in the production, characterization, field evaluation and commercialization of transgenic crop varieties worldwide. Likewise, significant advances have been made towards increasing crop yields, improving nutritional quality, enabling crops to be raised under adverse conditions and developing resistance to pests and diseases for sustaining global food and nutritional security. The overarching purpose of this 3-volume work is to summarize the history of crop improvement from a technological perspective but to do so with a forward outlook on further advancement and adaptability to a changing world. Our carefully chosen “case studies of important plant crops” intend to serve a diverse spectrum of audience looking for the right tools to tackle complicated local and global issues.

This book collates the basic and advanced concepts of plant biotechnology and genomics along with the future trends. It discusses the combination of conventional breeding techniques with genomic tools and approaches leading to a new genomics-based plant breeding technology supporting crop plants that respond better to biotic and abiotic stress, and pathogen attacks. Plant genomics play an important role in developing more efficient plant cultivars which are essential for the neo green revolution needed to feed the world’s rapidly growing population. Plant genomic data is being utilized in genetic engineering to ensure that better and resilient varieties of crops are available ensuring food security. This book is of immense interest to teachers, researchers, crop scientists, capacity builders, and policy makers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, biotechnology, genomics, soil science, and environmental sciences. National and International agricultural scientists and policy makers will also find this to be a useful read.

Annual Plant Reviews, Volume 23 A much clearer picture is now emerging of the fine structure of the plant cuticle and its surface, the composition of cuticular waxes and the biosynthetic pathways leading to them. Studies assessing the impact of UV radiation on plant life have emphasized the role of the cuticle and underlying epidermis as optical filters for solar radiation. The field concerned with the diffusive transport of lipophilic organic non-electrolytes across the plant cuticle has reached a state of maturity. A new paradigm has recently been proposed for the diffusion of polar compounds and water across the cuticle. In the context of plant ecophysiology, cuticular transpiration can now be placed in the perspective of whole-leaf water relations. New and unexpected roles have been assigned to the cuticle in plant development and pollen-stigma interactions. Finally, much progress has been made in understanding the cuticle as a specific and extraordinary substrate for the interactions of the plant with microorganisms, fungi and insects. This volume details the major developments of recent years in this important interdisciplinary area. It is directed at researchers and professionals in plant biochemistry, plant physiology, plant ecology, phytopathology and environmental microbiology, in both the academic and industrial sectors.

Commencing with a chapter which places Physcomitrella into phylogenetic position, this important publication then covers the following major topics. Population genetics, genome, transcripts and metabolomics, gene targeting, hormones, small RNAs, tip growth, chloroplasts, sporophyte development, desiccation and oxidative stress, sugar metabolism, and pathogenesis. With chapters contributed by many of the World's leading workers in the area, this landmark book is essential reading for all those studying plant evolutionary biology, genomics, molecular and cell biology and genetics.

First discovered as fungal metabolites, the gibberellins were recognised as plant hormones over 50 years ago. They regulate reproductive development in all vascular plants, while their role in flowering plants has broadened to include also the regulation of growth and other developmental processes. This timely book covers the substantial and impressive recent advances in our understanding of the gibberellins and their roles in plant development, including the biosynthesis, inactivation, transport, perception and signal transduction of these important hormones. An introductory chapter traces the history of gibberellin research, describing the many discoveries that form the basis for the recent progress. The exciting emerging evidence for the interaction of gibberellin signalling with that of the other hormones is critically evaluated. The occurrence of gibberellins in fungal, bacterial and lower plant species is also discussed, with emphasis on evolution. Manipulation of gibberellin metabolism and signal transduction through chemical or genetic intervention has been an important aspect of crop husbandry for many years. The reader is presented with important information on the advances in applying gibberellin research in agriculture and horticulture. Annual Plant Reviews, Volume 49: The Gibberellins is an important resource for plant geneticists and biochemists, as well as agricultural and horticultural research workers, advanced students of plant science and university lecturers in related disciplines. It is an essential addition to the shelves of university and research institute libraries and agricultural and horticultural institutions teaching and researching plant science.
