Project description:An overview of the expression pattern of all rice genes under natural field conditions based on microarray analysis of different organs and tissues at various stages of growth and development from transplanting to harvesting. A total of 48 samples representing organs/tissues at various stages of growth and development with 3 replicates each except for one anther sample with 2 replicates. Vegetative organs such as leaf blade, leaf sheath, root and stem were sampled during the vegetative, reproductive and ripening stages. Young inflorescence, anther, pistil, lemma, palea, ovary, embryo, and endosperm were sampled at various stages of development.

Project description:Plants initially undergo a period of vegetative development, in which it produces leaves from shoot apical meristem (SAM) and roots from the root apical meristem. Later in development, the SAM undergoes a change in fate and enters reproductive development called as floral transition, producing flowers and seeds. Our understanding of the molecular and genetic mechanisms that underlie reproductive development in plants has increased tremendously in the past decade, essentially through the work on Arabidopsis. In this study, we have analyzed the spatial and temporal gene expression in various tissues/organs and developmental stages of rice using microarray technology to identify the genes differentially expressed during various stages of reproductive development.

Later in development, the SAM undergoes a change in fate and enters reproductive development called as floral transition, producing flowers and seeds. Our understanding of the molecular and genetic mechanisms that underlie reproductive development in plants has increased tremendously in the past decade, essentially through the work on Arabidopsis. In this study, we have analyzed the spatial and temporal gene expression in various tissues/organs and developmental stages of rice using microarray technology to identify the genes differentially expressed during various stages of reproductive development. Experiment Overall Design: Various rice tissues/organs (seedling root, mature leaf and Y leaf) and stages of reproductive (panicle and seed) development were used for RNA extraction and hybridization on Affymetrix microarrays. Three biological replicates of each sample were used for microarray analysis. We sought to obtain developmental and temporal gene expression profiles at each stage to identify the differentially expressed genes. Different stages of panicle and seed development have been categorized according to panicle length and days after pollination, respectively, based on landmark developmental events as follows: up to 0.5 mm, shoot apical meristem and rachis meristem (SAM); 0-3 cm, floral transition and floral organ development (P1); 3-10 cm, meiotic stage (P2 and P3); 10-15 cm, young microspore stage (P4); 15-22 cm, vacuolated pollen stage (P5); 22-30 cm, mature pollen stage (P6); 0-2 dap, early globular embryo (S1); 3-4 dap, middle and late globular embryo (S2); 5-10 dap, embryo morphogenesis (S3); 11-20 dap, embryo maturation (S4); 21-29, dormancy and desiccation tolerance (S5). These stage specifications are approximations based on information from Itoh et al., 2005, Plant Cell Physiol, 46, 23-47.

Project description:The profiling was conducted with the Rice 3'-Tiling Microarray designed from 27,448 genes deposited at IRGSP, RAP1 database (http://rapdb.lab.nig.ac.jp). In this research, an array of 27,448 rice genes was used to elucidate the transcriptome of 7 tissues or organs of Oryza sativa L. cv. Dongjin including calli, regenerating calli, germinating seeds, leaves, roots, and flowers (before and after pollination) using a rice 3â² ORF tilling microarray. The ratio of standard deviation to the mean of microarray intensities was used to distinguish between organ-specific and constitutively expressed genes. Accordingly, the genes are classified into highly variable, variable, and constitutive groups. To isolate the organ-specific promoters, several genes were selected and validated in planta using reporter gene analysis. We found that the Os01g0702500, Os11g0211800, and Os01g0257300 promoters were active in the calli, germinating seeds, and roots, respectively. The Os08g0135500 promoter was shown to drive transgene expression in various organs of the mature flowers, such as the anther, lemma, and palea, whereas the Os03g0369100 promoter was only active in the anther. Lastly, the Os09g0553100 promoter induced high levels of reporter gene expression in all organs. The gene expression data from representative organs could put a frame work for large dataset collections and then subsequent profiling by subdivision of organ/tissues might be more efficient to find appropriate promoters. A total of 14 chips were used for microarray. Total RNAs were extracted from rice 7 tissues or organs of Oryza sativa L. cv. Dongjin including calli, regenerating calli, germinating seeds, leaves, roots, and flowers (before and after pollination. Experiments were duplicated.

Project description:Peromyscus leucopus transcriptomes of various organs and tissues
| PRJNA799627 | ENA
Project description:Transcriptional programs are important for the development of complex eukaryotic organisms. Suites of genes expressed with temporal and spatial controls by regulatory networks in response to environmental cues are the cornerstone for achieving the specification of morphology and physiology of the tissue or organ systems. Thus, an important issue of developmental biology is to define the subsets of expressed genes and their expression patterns that are related to the organ or tissue system. Rice is a model plant for cereal genome research. Although large amounts of data of whole genome expression have been generated in recent years in rice, the majority of the studies were designed to identify differentially expressed genes between controls and treatments with certain experimental conditions such as biotic, abiotic or light, or to investigate the comparative expression patterns between wild type and mutants of certain genes. Only in a few cases were the datasets designed for studying the transcriptomes of a limited number of organs and cell types. Thus, there is still insufficiency in the available datasets that would allow for the establishment of expression patterns for suits of genes during the developmental processes of rice. In this study, we collected 39 tissues/organs covering the life cycle of the rice from two indica varieties Minghui 63 and Zhenshan 97, and the Affymetrix GeneChip Rice Genome Array was used to investigate the transcriptomes of these organs. The objective was to develop a genomic resource of genome-wide dynamic transcriptome of the rice plant, which could be used as the reference gene expression map for rice and other cereals. Also, the dataset is used to identify the candidates of genes with potential functions in regulating the development of rice or breeding practice. Keywords: rice, expression profiling, life cycle, development, inflorescence To dissect the developmental transcriptomes of rice, a total of 39 tissues covering the entire tissue culture process and life cycle were sampled from two indica varieties Minghui 63 and Zhenshan 97. And the Affymetrix Genechip rice Genome Array was used to investigate their dynamic transcriptomes. Two independent biological replicates were sampled from most tissues, except two seedling and three panicle tissues, for which three independent biological replicates each with two technical replicates were sampled, resulting in a dataset of 190 microarrays.
