Orchid Genomics And Developmental Biology

This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.

This book provides information on genome complexity and evolution, transcriptome analysis, miRNome, simple sequence repeats, genome relationships, molecular cytogenetics, polyploidy induction and application, flower and embryo development. Orchids account for a great part of the worldwide floriculture trade both as cut flowers and as potted plants and are assessed to comprise around 10% of global fresh cut flower trade. A better understanding of the basic botanical characteristics, flower regulation, molecular cytogenetics, karyotypes and DNA content of important orchids will aid in the efficient development of new cultivars. The book also describes the composition, expression and function of various microRNAs and simple sequence repeats. Information on their involvement in all aspects of plant growth and development will aid functional genomics studies.

This book provides comprehensive insights into the existing and emerging trends in orchid biology based on the findings of omics, high-throughput technology, biotechnology, molecular breeding, and genome editing approaches in orchids. It illustrates molecular mechanisms of orchid mycorrhizal symbiosis according to the recent achievements of transcriptomics and bioinformatics studies which accelerate the progress of orchid research with the aid of their high-throughput tools. In this book, a comprehensive view of orchid breeding was presented, and it includes fundamental methods as well as advanced strategies through the combination of several technologies such as genetic engineering, omics, computational biology, and genome editing. These resulting knowledge and tools are highly beneficial for obtaining novel and fascinating varieties in the orchid market which is a competitive industry of global trade. Another interesting content is the focus on the production of orchid bioactive compounds and their values in the field of ethnomedicine. Their sources chiefly came from secondary metabolites and can be enriched through elicitors and produced more efficiently by improved tissue culture protocols and bioreactors. In this edited collection, we provided space for presenting an updated review of in vitro seed germination which is a routine technology for well-trained researchers but can give a complete demonstration for the potential audiences including growers and research beginners. This book collects refined knowledge from a broad source of scientific literature by experts in the field of orchid research and surely is an adequate reference and textbook for students, teachers, and researchers. It includes methods and applications of orchid breeding technology which would gain high attention from growers, breeders, and the related fields of agriculture.

For centuries plants of a broad taxonomical background have been bred and commercialized because of the beauty of their flowers. However, until recently genomic analyses of ornamentals remained a challenge because of their large genome sizes and high ploidy levels. In the last decade, increasingly affordable sequencing technologies and powerful bioinformatic approaches resulted in the complete sequencing of several horticultural species genomes and the characterization of their transcriptomes. These developments enabled research on many challenging topics. This Research Topic gives you a primer into them by featuring a broad range of original research contributions on some of the most active areas of ornamental plant research: the genetic basis of flower morphology, scent, and color, the genetic regulation of physiology as well as the epigenetic factors affecting vegetative development. In this context, one of the most significant hurdles to functional genetic studies in ornamentals is achieving efficient genetic transformation. Several articles in this Research Topic describe strategies to tackle this challenge and present insights into the way transgene activity renders novel flower phenotypes.

A benchmark text, Developmental Genetics and Plant Evolution integrates the recent revolution in the molecular-developmental genetics of plants with mainstream evolutionary thought. It reflects the increasing cooperation between strongly genomics-influenced researchers, with their strong grasp of technology, and evolutionary morphogenetists and sys

Current major interests in this area include the study of higher level phylogenetic relationships and character evolution in the angiosperms, floral evolution, the genetic basis of key floral differences in basal angiosperms, the genetic and genomic consequences of polyploid speciation, conservation genetics of rare plant species, and phylogeography. Developmental Genetics of the Flower provides a series of papers focused on the developmental genetics of flowering as well as the genetic control of the timing of flowering. Investigation of speciational mechanisms, evolutionary relationships, and character evolution in flowering plants and land plants utilizing a variety of experimental approaches are discussed. The chapters are excellent reviews of the current fast-moving area of research. Provides a brief review of genes known to regulate flower development Articles emphasize the classic ABC model of flower development
