Hormonal Signal Transduction in Rice
The compact nature of the rice genome provides a distinct advantage in gene isolation and genomic sequencing in contrast to other cereal crops. Further, the rice genome shows apparent syntenies with many other...

Chapter
Genetic Control of Embryogenesis in Rice
The fundamental body organization in higher plants is established during embryogenesis, although most morphogenetic events occur after embryogenesis (Jürgens et al. 1994; Meinke 1995). Like all of the sexually...

Chapter
Genetic Regulation of Meristem Maintenance and Organ Specification in Rice Flower Development
Molecular genetic studies in Arabidopsis thaliana over the last 15 years have produced a wealth of information that has considerably advanced our understanding of plant development at the molecular level. Among t...

Chapter
Molecular Studies on Cytoplasmic Male Sterility-associated Genes and Restorer Genes in Rice
Cytoplasmic male sterility (CMS) is a maternally inherited trait that results in the inability to produce fertile pollen, and is widely known in higher plants. Recent studies have identified that an aberrant c...

Chapter
Genetic Diversity in Wild Relatives of Rice and Domestication Events
Two cultivated rice species, Oryza saliva and O. glaberrima, are classified as the O. saliva complex, together with five related wild species. These wild taxa are O. rufipogon (Asia and Oceania), O. barthii (Afri...

Chapter
Chromosome and Genome Evolution in Rice
Genomic and species divergences in rice offer a major advantage in genetic and evolutional studies, as well as for practical breeding purposes. The genus Oryza is classified into nine genomes comprising 23 specie...

Chapter
Detection and Molecular Cloning of Genes Underlying Quantitative Phenotypic Variations in Rice
Sequencing of the entire rice genome has made remarkable progress (IRGSP 2005). This sequence information has provided new tools for genetics and has created a new paradigm of plant breeding. Many phenotypic t...

Chapter
Regulation of Iron and Zinc Uptake and Translocation in Rice
Higher plants take up essential nutrients from the rhizosphere, in which several nutrients tend to be insoluble, thus limiting their availability. Deficiencies of the micronutrients Fe and Zn constitute major ...

Chapter
The Rice Genome Sequence as an Indispensable Tool for Crop Improvement
Rice is one of the three major staple food crops in the world. In 2004, world rice production representing total rice yield was about 450 million tons. This indicates that the introduction of high-yielding ric...

Chapter
Health-promoting Transgenic Rice: Application of Rice Seeds as a Direct Delivery System for Bioactive Peptides in Human Health
The frequency of lifestyle-related diseases such as diabetes, hypertension and obesity has increased over the last few decades in the developed industrial nations. These diseases can lead to further serious co...

Chapter
Sequencing-based Measurements of mRNA and Small RNA
The whole-genome sequence of rice (Oryza sativa subsp. japonica cv Nipponbare) has been sequenced and the annotation of this genome has been performed and continues to be updated and improved by several organizat...

Chapter
High-throughput Transcriptome Analysis in Rice from a Genomic Perspective
The major goals of transcriptome analysis in rice (Oryza saliva L.) are to identify the transcribed regions in the rice genome and to understand the mechanisms of gene expression at the transcription level. Start...

Chapter
Homologous Recombination-dependent Gene Targeting and an Active DNA Transposon nDart-promoted Gene Tagging for Rice Functional Genomics
Rice is an important staple food for more than half the world’s population, and it has become the first crop plant to have its 389-Mb genome sequenced (IRGSP 2005). Even though various functional genomic tools...

Chapter
Frequent DNA Transfer Among Mitochondrial, Plastid and Nuclear Genomes of Rice During Evolution
Mitochondria and plastids are semiautonomous organelles that contain their own DNA. During evolution, it is thought that most of the genes of ancestral mitochondria and plastids, which appear to have originate...

Chapter
Rice Heterotrimeric G Protein Signaling
Signaling pathways regulated by heterotrimeric G proteins are well known to be essential in eukaryotic organisms. In the last decade, it has been shown that plants also have genes for the canonical subunits of...

Chapter
Photoperiodic Flowering in Rice
Rice (Oryza saliva L.) is a staple food for humans, especially in Asian countries, and it feeds about half of the world’s population. During domestication and recent breeding programs, flowering-time responses ha...

Chapter
Genetic Dissection of Sexual Reproduction in Rice (Oryza sativa L.)
Sexual reproduction is the most important step in increasing the genetic diversity of offspring. It is defined by two major events: meiosis and fertilization. Meiosis is a crucial event to form haploid spores ...

Chapter
Phylogeny and Biogeography of the Genus Oryza
Plants with characteristics of species belonging to the tribe Oryzeae were present in India more than 60 million years ago (Ma), early in the history of grasses (Prasad et al. 2005). This tribe is now represen...

Chapter
Rice Retroposon, p-SINE, and Its Use for Classification and Identification of Oryza Species
Short interspersed elements (SINEs) are retroelements found in a wide variety of eukaryote genomes. They are 70- to 500-bp repetitive DNA sequences and each has an internal promoter for RNA polymerase III, an ...

Chapter
Genetics of Speciation in Rice
One of the central issues of evolutionary biology is the origin of the species, although the definition of species is an endlessly debated issue (Coyne and Orr 2004). According to the biological species concep...
