Gene expression profiling for early rice stamen

ABSTRACT: Plant organ formation, or organogenesis is the process in which the primordium derived from shoot apical meristem develops into an organ with a given shape and proper function, through a series of cell division and differentiation. To decipher the genetic program underling plant organ formation, we targeted early rice stamen development that covers most important events in male organ formation and germ cell initiation in plants. Totally, seven samples were used in this experiment. Stamens of stages 2-6 was collected through microdissection under microscope. And to ensure the stamen primordia collected are at corresponding stages, rice panicles were cut in half longitudinally, one half for paraffin sectioning to confirm developmental stages and the other half for preparing GEP samples. Samples of primordial and just-expanded third leaves were used as controls because leaf and stamen are homolog organs. RNA was extracted and amplified with Two-Cycle Eukaryotic Target Labeling Assay kit, and then hybridized to microarrays. Three biological replicates were applied for each sample.

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.

Project description:Gene expression throughout the reproductive process in rice (Oryza sativa) beginning with primordia development through pollination/fertilization to zygote formation was analyzed. We analyzed 25 stages/organs of rice reproductive development including early microsporogenesis stages with 57,381 probe sets, and identified around 26,000 expressed probe sets in each stage. Fine dissection of 25 reproductive stages/organs combined with detailed microarray profiling revealed dramatic, coordinated and finely tuned changes in gene expression. Decrease of expressed genes in the pollen maturation process was observed in a similar way with Arabidopsis and maize. An almost equal number of ab initio predicted genes and cloned genes appeared or disappeared coordinated with developmental stage progression. A large number of organ-/stage-specific genes were identified; notably 2,593 probe sets for developing anther, including 932 probe sets corresponding to ab initio predicted genes. Analysis of cell cycle-related genes revealed that several CDKs, cyclins and components of SCF E3 ubiquitin ligase complexes were expressed specifically in reproductive organs. Cell wall biosynthesis or degradation protein genes and transcription factor genes expressed specifically in reproductive stages were also newly identified. Rice genes homologous to reproduction-related genes in other plants showed expression profiles both consistent and inconsistent with their predicted functions. The rice reproductive expression atlas is likely to be the deepest and most comprehensive dataset available, indispensable for unraveling functions of many specific genes in plant reproductive processes that have not yet been thoroughly analyzed. Keywords: developmental stage comparison, tissue comparison, platform comparison Anther development of rice from hypodermal archesporial cells formation to tri-cellular mature pollens were divided into eight stages. Three or four biological replicates at each stage were analyzed with Affymetrix Rice Genome Array, and total number of samples in this series is 26.
