Fertilization in Higher Plants
Biotechnological methods are opening new ways in plant breeding. They allow novel strategies for improving crop productivity and quality, especially in the agrofood sector. The molecular mechanisms underlying these biotechnological approaches are presented here. Topics included are: pollen development, pollen tube growth, macrosporogenesis and fertilization and the effects of pesticides on sexual plant reproduction. Fertilization in higher plants is a complex process consisting of two events, the fusion of the egg with one sperm cell resulting in the diploid zygote, and the fusion of embryosac nuclei with another sperm cell, leading to a triploid endosperm. This "double fertilization" is preceded by the pollination process and a long lasting interaction between the dipoid pistil and the haploid pollen tube (progamic phase). Fertilization of flowering plants results in the formation of seeds and fruits, our basic food supply.
Education for Responsibility
Changing your mind to change the world is the general principle proposed to educate for responsibility. Using an interdisciplinary scientific approach, this book dissects the functioning of the ego, that is to say the belief in a self, an illusion that causes disharmony. After an original modeling of the notion of responsibility, the author deduces that it is incumbent on all of us to become aware of the relationship between our own minds and the world. Thus, gaining consistency and awareness, everyone would have the potential to free themselves from the illusion of the ego and contribute to a more harmonious world. This book therefore proposes psychospiritual skills, favored in particular by different forms of reflexivity and by meditation (and mindfulness), which can serve as a basis for a curriculum to educate for responsibility. This academic connection between meditation and ethics is a major innovative contribution.
Sex Determination in Plants
Indispensable for all plant biologists, this is a fascinating and thorough examination of those factors which affect the sex determination of plant species, describing all of the main classes of plant with unisexual flowers hermaphrodite, monoecious and
Plant Molecular Biology Manual
During the past ten years, great advances have been made in the area of plant molecular biology. Such formerly esoteric techniques as gene transfer and plant regeneration are now routinely performed, making the dissection of regulatory elements of genes a common practice in many laboratories. Along with this new technology has come an almost bewildering array of rapidly changing techniques, often making it difficult for the novice to select and perform the technique most appropriate for answering a given biological question. In 1986, some of us felt that many of these techniques had become routine enough to warrant the publication of a laboratory manual. The manual is designed both for advan...
Plant Protoplasts and Genetic Engineering V
In continuation of Volumes 8, 9, 22, and 23, this new volume deals with the regeneration of plants from isolated protoplasts and genetic transformation in various species of Actinidia, Allocasuarina, Anthurium, Antirrhinum, Asparagus, Beta, Brassica, Carica, Casuarina, Cyphomandra, Eucalyptus, Ipomoea, Larix, Limonium, Liriodendron, Malus, Musa, Physcomitrella, Physalis, Picea, Rosa, Tagetes, Triticum, and Ulmus. These studies reflect the far-reaching implications of protoplast technology in genetic engineering of plants. The book contains a wealth of useful information for advanced students, teachers, and researchers in the field of plant tissue culture, molecular biology, genetic engineering, plant breeding, and general biotechnology.
The Benefits of Imperfection
The cult of performance leads our society to emphasise the values of success and continuous optimisation in all areas. Slowness, redundancy and randomness are therefore negatively perceived. Olivier Hamant, in his book, reclaims them by his knowledge of biological processes. What can we learn from life sciences? While some biological mechanisms certainly boast formidable efficiency, recent advances instead highlight the fundamental role of errors, incoherence or slowness in the robustness of living organisms. Should life be considered suboptimal? To what extent could suboptimality become a counter-model to the credo of performance and control in the Anthropocene? In the face of pessimistic observations and environmental alerts, the author outlines solutions for a future that is viable and reconciled with nature. Key Features: Solidly documents with a grounding in scientific facts focusing on solutions Explores a pragmatic way towards robustness, moving the debate beyond performance, technolatry or degrowth Responds to eco-anxiety by providing an engaging and viable way forward
