Download or read book Fertilization in Higher Plants written by Mauro Cresti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Annual Plant Reviews Flowering and its Manipulation written by Charles Ainsworth and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Investigating Molecular Mechanisms of Flowering Time Across Plant Lineages written by Kevin Scott Mayer and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flowering plants represent a large and diverse land plant lineage. Critical to their reproductive success has been the evolution of mechanisms to ensure proper timing of flowering. Plants cue flowering as they age, and further coordinate with the sensing of environmental signals such as changing daylengths and seasonal temperatures. The molecular genetics of flowering in the model Arabidopsis thaliana are well characterized, however, relatively little is known in other species. Study of diverse lineages suggests mechanisms regulating flowering time have evolved independently. A conserved feature is the importance of chromatin in regulating flowering time genes. We screened a library of Arabidopsis histone deacetylase mutations and found that HDA9 forms a conserved complex with PWR and HOS15. HDA9-PWR-HOS15 represses flowering through the autonomous pathway. We provide a literature review of the involvement of the Arabidopsis HDAC superfamily in flowering. To overcome redundancy, we created and characterized higher order mutants of the Class I HDAC mutants (hda9/6/19), allowing us to more precisely define their roles in flowering. To explore flowering in other plant lineages, we are studying the temperate grass Brachypodium distachyon. To develop Brachypodium as a model organism, we conducted a study to determine optimal light conditions for indoor growth. We settled on an LED source that results in favorable traits such as compactness and shortened generation time. Finally, we provide an update to discuss how forward and reverse genetics has led to progress in understanding Brachypodium's flowering pathway. Future studies will continue to characterize genes to better understand the molecular basis of vernalization.

It explores three main themes: the external and internal regulation of flowering, floral development, and fertilisation and gametophyte development, and includes new chapters on the evolution of flowers, floral senescence and apomixis.
Download or read book The Identification of Molecular Mechanisms of Brachypodium Distachyon Flowering written by Aaron Lomax and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant's survival relies on the adaptation of their growth and development to the surrounding environmental conditions. A key developmental transition strongly influenced by environmental cues is the change from vegetative to reproductive growth. For example, plants adapted to temperate climates must avoid flowering in the winter when environmental conditions are significantly less favorable for reproductive success than spring and summer. One adaptation seen in a diverse range of flowering plants is the vernalization requirement, the process by which prolonged cold exposure results in the competence to flower. The majority of the molecular characterization of this response has been done in the eudicot Arabidopsis thaliana. Recent studies have shown that vernalization likely evolved independently in different plant lineages thus preventing the transposition of the molecular knowledge acquired in A. thaliana to other families of plants. To build upon our understanding of flowering in temperate grasses, we performed genetic screens in Brachypodium distachyon for mutants that flower early without vernalization. By screening for early flowering mutants, we were able to identify genes that affect flowering either through specific processes or through broad regulatory functions. From these screens we identified BdEZL1, the catalytic subunit of Polycomb repressive complex 2 (PRC2). This complex inhibits flowering through the transcriptional repression of a large number of genes, including several flowering regulators. We also isolated a mutant in a novel gene that appears to function specifically in the regulation of flowering by modulating the vernalization response.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.
Download or read book Photoperiodism in Plants written by Brian Thomas and published by Elsevier. This book was released on 1996-10-17 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoperiodism is the response to the length of the day that enables living organisms to adapt to seasonal changes in their environment as well as latitudinal variation. As such, it is one of the most significant andcomplex aspects of the interaction between plants and their environment and is a major factor controlling their growth and development. As the new and powerful technologies of molecular genetics are brought to bear on photoperiodism, it becomes particularly important to place new work in the context of the considerable amount of physiological information which already exists on the subject. This innovative book will be of interest to a wide range of plant scientists, from those interested in fundamental plant physiology and molecular biology to agronomists and crop physiologists. Provides a self-sufficient account of all the important subjects and key literature references for photoperiodism Includes research of the last twenty years since the publication of the First Edition Includes details of molecular genetic techniques brought to bear on photoperiodism
