The development of new plant varieties is a long and tedious process involving the generation of large seedling populations for the selection of the best individuals. While the ability of breeders to generate large populations is almost unlimited, the selection of these seedlings is the main factor limiting the generation of new cultivars. Molecular studies for the development of marker-assisted selection (MAS) strategies are particularly useful when the evaluation of the character is expensive, time-consuming, or with long juvenile periods. The papers published in the Special Issue “Plant Genetics and Molecular Breeding” report highly novel results and testable new models for the integr...
In the summer of 1992 a distinguished group of molecular, population and evolutionary geneticists assembled on the campus of the University of Georgia in Athens, USA to discuss the relevance of their research to the role played by transposable elements (TEs) in evolution. The meeting consisted of a series of informal discussions of issues brought up in papers written by the participants and distributed among them prior to the meeting. These papers and the transcripts of the ensuing discussions are presented in this volume.
This collection of 101 short communications, submitted by some of the participants at the 11th Nuclear Workshop held in Suzdal, USSR, 18-23 September, 1989, provides a representative survey of the material presented at the Workshop. Articles have been submitted by both those who delivered lectures and those who had poster presentations. The order of presentation at the Nuclear Workshop is roughly maintained within this proceedings book, but the session titles within the scientific program have not been utilized as discrete subdivisions within the book, because of the considerable overlap of subject matter. The overall sequence is as follows: Genome structure, Gene Structure and Expression, N...
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
This book is dedicated to understanding how miRNAs affect translation. It includes chapters representing work in plants and Caenorhabditis elegans, the biological systems that originally led to the discovery of small interfering RNAs.
Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for our children. This discipline addresses current issues such as climate change, increasing food and fuel prices, starvation, obesity, water pollution, soil erosion, fertility loss, pest control and biodiversity depletion. Novel solutions are proposed based on integrated knowledge from agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, philosophy and social sciences. As actual society issues are now intertwined, sustainable agriculture will bring solutions to build a safer world. This book series analyzes current agricultural issues and proposes alternative solutions, consequently helping all scientists, decision-makers, professors, farmers and politicians wishing to build safe agriculture, energy and food systems for future generations.
Silence in language learning is commonly viewed negatively, with language teachers often struggling to interpret learner silence and identify whether it is part of communication, mental processing, or low engagement. This book addresses silence in language pedagogy from a positive perspective, translating research into practice in order to inform teaching and to advocate greater use of positive silence in the classroom. The first half of the book examines the existing research into silence, and the second half provides research-informed practical strategies and classroom tasks. It offers applicable principles for task design that utilises rich resources, which include visual arts, mental representation, poetry, music, and other innovative tools, to allow both silence and speech to express their respective and interrelated roles in learning. Comprehensive yet accessible, it is essential reading for academic researchers and students in applied linguistics, TESOL, and language teaching, as well as for language teachers and educators.
In recent years, the traditional way of teaching has been substituted by online teaching. Teachers have had to think about efficient and effective teaching methods and activities in online delivery that can keep students interested and engaged. It is important to examine teacher cognition and its relevance to classroom management and teaching practice as the role of technology in teaching and learning cannot be overestimated. The Handbook of Research on Teacher and Student Perspectives on the Digital Turn in Education examines the cognitions of teachers and students, their attitudes and perceptions regarding online teaching, and their personal experiences and challenges regarding the use of online platforms and digital tools. This book discusses the implementation of digital technologies in primary, secondary, and tertiary education that facilitates the learning and teaching process and creates a student-centered environment. Covering topics such as digital literacy, student engagement, and pedagogy, this reference work is an essential resource for practitioners, scholars, administrators, policymakers, researchers, academicians, instructors, and students.
Epigenetics commonly acts at the chromatin level modulating its structure and consequently its function in gene expression and as such plays a critical role in plant response to internal and external cues. This book highlights recent advances in our understanding of epigenetic mechanisms as a major determinant through which internal and external signals, such as those occurring during hybridization, flowering time, reproduction and response to stress, communicate with plant cells to bring about activation of multiple nuclear processes and consequently plant growth and development. The outcome of these processes may persist for generations long after the initial cues have expired and may contribute to plant evolution.
