Abby, Seth, and Frances are teenagers bound by a shared tragedy—a deadly act of environmental protest in their coastal community of Scallop Bay. All three are searching for resolution to their grief. Eighteen months after the bombing that claimed her parents, her grandmother, and her sight, Abby makes an astonishing discovery on the beach—a giant Wandering Albatross has come ashore. How did this Antarctic bird that depends upon strong wind for flight cross the windless equatorial doldrums into the north Pacific? Is his presence merely the freshest augury of a global environment in crisis? What is the mysterious rock, pulsing with the mysterious heartbeat, that accompanies the bird? Over ...

Essential writings from the catalyst of the Latin American experimental tradition For the first time in English, readers can now evaluate the extraordinary breadth of César Vallejo's diverse oeuvre that, in addition to poetry, includes magazine and newspaper articles, chronicles, political reports, fictions, plays, letters, and notebooks. Edited by the translator Joseph Mulligan, Selected Writings follows Vallejo down his many winding roads, from Santiago de Chuco in highland Peru, to the coastal cities of Trujillo and Lima, on to Paris, Madrid, Moscow, and Leningrad. This repeated border-crossing also plays out on the textual level, as Vallejo wrote prolifically across genres and, in many ...
Rice is the most important cereal crop which feeds more than half the population of the world. It is being grown in more than 144. 641 million ha with a production of over 468. 275 million tons (in 1988). Rice is attacked by a large number of pests and diseases which cause an enormous loss in its yield. Therefore, the major objectives in rice breeding are the development of disease resistance, tolerance to insects, adverse soil water, and drought; and improvement of quality including increased protein content. Tremendous efforts being made at the International Rice Research Institute have resulted in the release of improved varieties. It is estimated that the world's annual rice production m...

In vitro Embryogenesis in Plants is the first book devoted exclusively to this topic. As the ultimate demonstration of totipotency in plants, somatic and haploid embryogenesis is of vital importance to all those working on or interested in basic and applied aspects of plantlet information and regeneration. The text includes comprehensive reviews written by experts, on all facts of in vitro and in vivo embryogenesis. Some chapters deal with the morphogenic, structural and developmental, physiological and biochemical, and molecular biological aspects of the subject. Chapters are also devoted to haploid embryogenesis, asexual embryogenesis in nature, zygotic embryogenesis, and zygotic embryo culture. Detailed tables summarizing successful somatic embryogenesis in all vascular plants are also included. This book, therefore, brings together previously scattered information to provide an indispensable reference book for both active researchers, graduate students and anyone interested in this aspect of tissue culture technology and plant development.
While working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (1974-1976), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts. In numerous stimu lating discussions with Professor Reinert on this subject, I was fully convinced that somatic embryogenesis would become one of the most important areas of study, not only regarding basic and fundamental aspects, but also for its application in crop improvement. During the last decade, we have witnessed tremendous interest and achievements in the use of somatic embryos for the production of synthetic seeds, ...
Thirty-five chapters on various aspects of fusion of plant protoplasts and somatic hybridization deal with the regeneration of interspecific and intergeneric somatic hybrids and cybrids in various plants: cereals, grasses, legumes, potato, tomato, eggplant, lettuce, Brassica, Datura, Hyoscyamus, Nicotiana, Catharanthus, Rauwolfia, Citrus, Poncirus, Prunus, Pyrus, Populus, algae, bryophytes, and ferns. The implications of somatic hybridization in gene transfer in wide crosses and for the induction of genetic variability in various crops are discussed. The book is an invaluable source of information for advanced students, teachers, and research scientists in the field of plant breeding, genetic engineering, plant tissue culture, and general plant biotechnology.
Legumes include many very important crop plants that contribute very critical protein to the diets of both humans and animals around the world. Their unique ability to fix atmospheric nitrogen in association with Rhizobia enriches soil fertility, and establishes the importance of their niche in agriculture. Divided into two volumes, this work presents an up-to-date analysis of in vitro and recombinant DNA technologies for the improvement of grain, forage and tree legumes. Volume 10B presents the current state and future prospects of in vitro regeneration and genetic transformation expression and stability of transgenes modification of traits in almost all the important legumes, for example: soybean; peanut; pea; french bean; chick pea; pigeon pea; cowpea; mung bean; black gram; azuki bean; lentil; Lathyrus; lupinus; Lotus spp; Medicago spp; Trifolium spp; Winged bean; Guar; and tree legumes for their improvement.
