The Orchid Genome

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 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!

Orchid Biotechnology IV presents a series of recent work on both basic and applied researches in biotechnology progress for Phalaenopsis, Oncidium and Erycina pusila orchids. These include breeding of Phalaenopsis orchids of black flower, big-white flower and small and floriferous flowers, physiology for shipping and photosynthesis, SSR markers and mitochondrial DNA markers, virus detection and antiviral immunity, embyogenesis and relationship with mycorrhiza symbiosis, transposon and retrotransposon, orchid genome and evolution, regulation of orchid floral scent, floral color modification, and abiotic stress tolerance.The diversity and specialization in orchid floral morphology have fascinated botanists and collectors for centuries. The orchid industry has been growing substantially worldwide. To advance the orchid industry, enhancement of basic research as well as advanced biotechnology will provide a good platform to improve the flower quality and the breeding of new varieties. This book provides a first-hand and up-to-date information on orchid breeding, orchid genome evolution, detection of virus in nanotechnology, molecular markers for cultivar identification for orchid lovers, researchers and industry growers.

This book provides a first hand and complete information on orchid biotechnology for orchid lovers, graduate students, researchers and industry growers. It contains comprehensive genomics and transcriptomics data, and a thorough discussion of the molecular mechanism of orchid floral morphogenesis. The contributors to the book are all orchid enthusiasts with more than 20 years' experience in the field. With more than 25,000 species, orchids are the most species-rich of all angiosperm families. They show wide diversity of epiphytic and terrestrial growth forms and have successfully colonized almost every habitat on earth. Orchids are fantastic for their spectacular flowers with highly evolved petal, labellum, and fused androecium and gynoecium, gynostemium, to attract pollinators for effective pollination. In addition, orchids have attracted the interest of many evolutionary biologists due to their highly specialized evolution and adaptation strategies. Orchid Biotechnology III covers the most update knowledge of orchid biotechnology research on Phalaenopsis, Oncidium, Cymbidium, Anoectohilus, Paphiopedilum, and Erycina pusilla. It will provide graduate students, researchers, orchid lovers and breeders with an opportunity to understand the mechanism why the orchids are so mysterious and spectacular. Hopefully, this information will be helpful for breeders to enhance orchid breeding and create even more elegant and grace flowers.

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.

Orchid Biotechnology II presents a series of recent works on both basic and applied researches in biotechnology progress for Phalaenopsis and Oncidium orchids. These include the development of flower, ovule, gynostemium and perianth, the discovery of new orchid-infecting viruses and virus movement, secondary metabolites, technology of DNA endoduplication and genetic transformation, growth regulation by micronutrition and orchid mycorrhiza, and plant growth substances for flowering. The diversity and specialization in orchid floral morphology have fascinated botanists and collectors for centuries. The orchid industry has been growing substantially in the past ten years worldwide. This book focuses on the recent advances in the research of orchid biotechnology from the past ten years in Taiwan. To advance the orchid industry, enhancement of basic research as well as advanced biotechnology will provide a good platform to improve flower quality and breeding of new varieties.
