Book Description
Apomixis in Plants presents a comprehensive review of different aspects of asexual seed formation in plants. This is important in plant research since apomixis could greatly facilitate breeding in important crops. It is also interesting theoretically because it carries problems related to genetic variation and evolution to its extreme. The book features a broad selection of topics, including a historical review of ideas and landmarks in the field; comparisons with other types of asexual reproduction in higher plants and with related phenomena in animals and related plants; a presentation of cytology and embryology of apomicts and the diversified terminology in the field; views on the genetic background of apomixis and environmental effects on its expression; and the interrelation between apomixis and other traits. Additional topics covered include classical and modern theories of sexual versus asexual reproduction; geographical and taxonomical trends in apomicts; ecological implications of apomixis, and a review of future possibilities for using apomixis in plant breeding. Apomixis in Plants is an important reference volume for researchers and students in all areas of botany, ecology, and plant breeding.

Book Description
Apomixis is the consequence of a concerted mechanism that harnesses the sexual machinery and coordinates developmental steps in the ovule to produce an asexual (clonal) seed. Altered sexual developments involve widely characterized functional and anatomical changes in meiosis, gametogenesis, and embryo and endosperm formation. The ovules of apomictic plants skip meiosis and form unreduced female gametophytes whose egg cells develop into a parthenogenetic embryo, and the central cells may or may not fuse to a sperm to develop the seed endosperm. Thus, functional apomixis involves at least three components, apomeiosis, parthenogenesis, and endosperm development, modified from sexual reproduction that must be coordinated at the molecular level to progress through the developmental steps and form a clonal seed. Despite recent progress uncovering specific genes related to apomixis-like phenotypes and the formation of clonal seeds, the molecular basis and regulatory network of apomixis is still unknown. This is a central problem underlying the current limitations of apomixis breeding. This book collates twelve publications addressing different topics around the molecular basis of apomixis, illustrating recent discoveries and advances toward understanding the genetic regulation of the trait, discussing the possible origins of apomixis and the remaining challenges for its commercial deployment in plants.

Book Description
Apomixis in Angiosperms: Nucellar and Integumentary Embryony is based on original cytoembryological data and critically reviewed literature on more than 250 species from 57 families of angiosperms. The book covers the complete process of nucellar and integumentary embryo formation and viable seed development within species, families, and among angiosperms in general. Many species (some of which are economically important) characterized by adventive embryony are listed. The book also provides an original simple classification of apomixis and offers a new approach to differentiating embryological structures in cases of apomixis and amphimixis. Apomixis in Angiosperms: Nucellar and Integumentary Embryony will be a useful reference for embryologists, botanists, cytologists, geneticists, and plant breeders. It will also benefit any researcher interested in studying somatic embryo formation in tissue culture.

Book Description
Thirty-four years have elapsed since the publication of the late Professor P. Maheshwari's text, An Introduction to the Embryology of Angiosperms, a work which for many years served as an invaluable guide for students and a rich source book for research workerso Various texts dealing with sections of the braad spectrum oftopics encompassed by Maheshwari in his book have appeared in the interim, but a compendious modem work dealing with the whole field has been lacking. This present volume splendidly meets the need, and it is altogether fitting that Professor B. M. lohri, long an associate and close colleague of Professor Maheshwari and himself a prolific contributor to the subject, should have undertaken the task of editing it. When Maheshwari wrote, it was stiIl feasible for one author to handIe the subject, but today even someone with his fine bread th of vision and depth of understanding could not, alone, do it justice. So the effort has to be a collaborative one; and Professor lohri's achievement has been to bring together a team of authoritative collaborators, assign them their responsibilities, and put them to work to produce a text as integrated in its treatment as the diversity of the subject would allow. The product vividly illustrates the advances that have been made in the study of angiosperm reproductive systems in the last 30 years, and the book is surely destined to become the new standard for student and researcher alike.

Book Description
Biotechnology and the Politics of Plants explores the mysterious phenomenon of ‘apomixis’, the ability of certain plants to ‘self-clone’, and its potential as a revolutionary tool for agriculture and enhancing food security, that may soon be a reality. Through historical anthropological and ethnographic study, Matt Hodges traces the development of the CIMMYT Apomixis Project, a prominent frontier research initiative, and its reinvention as a leading public-private partnership. He analyzes the fast-moving historical transition from public sector, mixed plant breeding approaches grounded in genetics, to a contemporary era of agricultural biotechnology and genomics where PPPs are a leading format, and explores how social contexts of research shape how knowledge is produced, as well as what remains ‘unknown’, and constrain the development of an ‘Apomixis Technology’. The chapters present an inventive approach informed by the anthropology of time, science and technology studies, and dialogue with the work of Gilles Deleuze, Paul Rabinow, Hannah Arendt, Andrew Pickering, and Eduardo Viveiros de Castro. Hodges outlines novel ways of integrating notions of history and becoming, and considers how apomixis offers up an alternative image of thought to theoretical concepts such as the well-known ‘rhizome’. The book makes a valuable contribution to both the growing social scientific literature on genomics and biotechnology, and recent anthropological debates on time and history.
