Gene Expression Profiling during Male Gametophyte Development in Rice

ABSTRACT: To investigate the potential function of miRNAs during male gametogenesis in rice, we first obtained gene expression profiles by using Affymetrix microarray technologies. In genome-scale, we found a common characteristic shared by rice and Arabidopsis, which vast of genes are down regulated from Pb to Pc stage. next, a total of 13363 genes were detected during the gametophyte development in rice, which contains 2925 pollen-enriched/-specific genes including 107 transcription factors. We also analyzed the microarray-based expression patterns of genes in miRNA pathways, and found 3 pollen-specific AGO genes (AGO12, AGO13 and AGO17). This subseries contains three datasets of gene expression in pollen development stages: uninucleate microspore (UNM/Pa), bicellular pollen (BCP/Pb) and tricellular pollen (TCP/Pc)

Plant microRNAs (miRNAs) act as negative regulators of gene expression by slicing target transcripts or inhibiting translation. A number of miRNAs play important roles in development. In order to investigate the potential function of miRNAs during male gametogenesis in rice, we obtained both gene and small RNA expression profiles by combining microarray and high-throughput sequencing technologies. From the microarray datasets, 2,925 male gametophyte-specific genes were identified, including 107 ...[more]

Profiling of small RNA populations in uninucleate microspores and bicellular pollen of rice

Project description:There are multiple types of small RNAs that may affect rice pollen’s development. To investigate the small RNA populations’ change during rice pollen development, 13-40 nt RNA were extracted from uninucleate microspores (UNM) and bicellular pollen (BCP) for high throughput sequencing. Together with our laboratory’s previous published rice tricellular pollen (TCP) small RNA sequencing data (GSM722128), sharp increase of tRNA fragments (tRFs) in BCP stage and a slightly decreased tRFs in TCP were found. Among which, new lengths of tRFs were also discovered. Our work accomplished the knowledge about tRFs in rice pollen development.

RNA sequencing of Oryza sativa japonica control and OsRALF17/19 knockout mutant in mature rice anthers

Project description:Pollen tube growth is essential for successful fertilization and stable crop yields. We constructed loss-of-function/knock-out mutants that simultaneously target two rice genes using the CRISPR/Cas9 mutagenesis system. The selected OsRALF17 and OsRALF19 genes are strongly expressed in rice bicellular/tricellular pollen and have essential functions in the pollen tube growth. For the corresponding transcriptomic analysis, we sampled mature pollen anthers from a control group and an OsRALF17/19 knock-out mutant.

Separated Transcriptomes of Male Gametophyte and Tapetum in Rice

Project description:In flowering plants, the male gametophyte, the pollen, develops in the anther. Complex patterns of gene expression in both the gametophytic and sporophytic tissues of the anther regulate this process. The gene expression profiles of the microspore/pollen and the sporophytic tapetum are of particular interest. In this study, a microarray technique combined with laser microdissection (44K LM-microarray) was developed and used to characterize separately the transcriptomes of the microspore/pollen and tapetum in rice. Expression profiles of 11 known tapetum specific-genes were consistent with previous reports. Based on the spatiotemporal expression patterns and gene ontology (GO) categories of anther-expressed genes, some noteworthy expression patterns are discussed in connection with various important biological events of anther development. The separated transcriptomes of rice microspore/pollen and tapetum were measured at the premeiosis, meiosis, tetrad, uninuclear, bicellular, and tricelluar stages by using laser microdissection (LM)-mediated microarray.

MicroRNA Profiles and Their Control of Male Gametophyte Development in Rice

Project description:Plant microRNAs (miRNAs) act as negative regulators of gene expression by slicing target transcripts or inhibiting the translation, and a number of miRNAs play important roles in development. In order to investigate the potential function of miRNAs during male gametogenesis in rice, we obtained both gene and small RNA expression profiles by combining Affymetrix microarray and high-throughput sequencing technologies. In genome-scale, we compared arrays and sRNA-Seq datasets in different stages/organs of rice by applying computational and statistical approaches. Subsequently, we identified 13363 expressed genes and 104 expressed unique miRNAs in pollen, thus, we constructed an interaction network of miRNA-target basing on two datasets. By employing enrichment analysis, we found miRNA-regulated targets involved in both up and down pathways, but predominantly in down pathways including 30 GO biological processes and 34 KEGG pathways. Our findings indicated that miRNAs plays a broad regulatory role during male gametophyte development in rice. This SuperSeries is composed of the following subset Series: GSE29080: Gene Expression Profiling during Male Gametophyte Development in Rice GSE29178: Profiling of small RNA populations in tricellular pollen of rice

Characterization of the small RNA populations of developing Arabidopsis thaliana pollen.

Project description:Small RNA diversity and function has been widely characterized in various tissues of the sporophytic generation of the angiosperm model Arabidopsis thaliana. In contrast, there is limited knowledge about small RNA diversity and their roles in developing male gametophytes. We thus carried out small RNA sequencing on RNA isolated from four stages of developing Arabidopsis thaliana pollen. Spores from 4 stages of pollen development (UNM: Uninucleate microspore M-bM-^@M-^S BCP: Bicellular pollen M-bM-^@M-^S TCP: Tricellular pollen M-bM-^@M-^S MP: Mature pollen) were isolated using a percoll gradient-based method (Honys and Twell, 2004) and the small RNA fraction for each sample was isolated and sequenced by Illumina technology.

Global gene expression profiles among five independent cytoplasmic male sterile lines.

Project description:We employed a microarray-based transcriptomic status comparison of rice cytoplasmic male sterile (CMS) lines in order to categorize the nuclear gene expressions upon cytoplasmic substitution. In anthers at the uninucleate and bicellular pollen stages, we found that 8,199 genes significantly changed their expression in at least one of the CMS lines. We categorized the genes into 100 clusters by k-means clustering, and common obvious expression patterns were observed in W11, LD and BT.
