Transcriptome profiling in reciprocal hybrids and tetraploids constructed from subspecies japonica and indica of Asian rice (Oryza sativa L.)

ABSTRACT: Hybrids and allopolyploids typically exhibit radically altered gene expression patterns relative to their parents, a phenomenon termed âtranscriptomic shock.â To distinguish the effects of hybridization from polyploidization on coregulation of divergent alleles, we analyzed expression of parental copies (homoeologs) of 11,608 genes using RNA-seq-based transcriptome profiling in reciprocal hybrids and tetraploids constructed from subspecies japonica and indica of Asian rice (Oryza sativa L.)

Hybridization and polyploidization are prominent processes in plant evolution. Hybrids and allopolyploids typically exhibit radically altered gene expression patterns relative to their parents, a phenomenon termed "transcriptomic shock." To distinguish the effects of hybridization from polyploidization on coregulation of divergent alleles, we analyzed expression of parental copies (homoeologs) of 11,608 genes using RNA-seq-based transcriptome profiling in reciprocal hybrids and tetraploids const ...[more]

Oryza sativa Transcriptome or Gene expression

Project description:A biological phenomenon in which hybrids exhibit superior phenotypes from its parental inbred lines known as heterosis, has been widely exploited in plant breeding and extensively used in crop improvement. Hybrid rice has immense potential to increase yield over other rice varieties and hence is crucial in meeting increasing demand of rice globally. Moreover, the molecular basis of heterosis is still not fully understood and hence it becomes imperative to unravel its genetic and molecular basis. In this context, RNA sequencing technology (RNA-Seq) was employed to sequence transcriptomes of two rice hybrids, Ajay and Rajalaxmi, their parental lines, CRMS31A (sterile line, based on WA-CMS) and CRMS32A (sterile line based on Kalinga-CMS) respectively along with the common restorer line of both hybrids, IR-42266-29-3R at two critical rice developmental stages viz., panicle initiation (PI) and grain filling (GF). Identification of differentially expressed genes (DEGs) at PI and GF stages will further pave the way for understanding heterosis. In addition, such kind of study would help in better understanding of heterosis mechanism and genes up-regulated and down-regulated during the critical stages of rice development for higher yield.

Epigenetic variation through the breeding processes of maize

Project description:The concurrent epigenetic changes during this period of remarkable improvement in maize grain yield remain unknown. Here, we performed MethylC-seq and RNA-seq on 4 related inbred lines with known pedigree information. Analysis of epigenetic changes over the course of historical maize breeding is a valuable new avenue in the exploration for crop improvement. These data lead us to suggest that novel epihaplotypes, in addition to DNA variation, are a substrate of selection during breeding, and that epigenetic variation between parents may also contribute to heterosis in hybrids.

Zea mays Transcriptome or Gene expression

Project description:In many eukaryotes, reproduction involves contributions of genetic material from two parents. At some genes there are parent-of-origin differences in the expression of the maternal and paternal alleles of a gene and this is referred to as imprinting. The analysis of allele-specific expression in several maize hybrids allowed the comprehensive detection of imprinted genes. By comparing allelic expression patterns in multiple crosses, it was possible to observe allelic variation for imprinting in maize. The comparison of genes subject to imprinting in multiple plant species reveals limited conservation for imprinting. The subset of genes that exhibit conserved imprinting in maize and rice may play important, dosage-dependent roles in regulation of seed development. In this study, deep sequencing of RNA isolated from 14 days-after-pollination (DAP) endosperm tissue of five reciprocal hybrid pairs was performed to identify imprinted genes.

Physcomitrella patens cultivar:Gransden Transcriptome or Gene expression

Project description:In this study we used single-cell type transcriptomics to identify more than 4,000 differentially expressed (DE) genes that distinguish uniplanar protonematal tip cells from multiplanar gametophore bud cells in the moss Physcomitrella patens. While the transcriptomes of both tip and bud cells harbor molecular signatures of proliferative cells, the bud cell transcriptomes exhibit a wider variety of upregulated genes. Our data suggest that the combined expression of genes regulating shoot patterning and asymmetric cell division accompanied the transition from uniplanar to triplanar meristematic growth in moss.

Detection of large intergenic non-coding RNA

Project description:Members of the ARGONAUTE gene family are known to have roles in RNA-mediated silencing during development. One of these, MEL1, was shown to be germ-cell specific and essential for progression through sporogenesis at both premeiotic mitosis and meiosis. To understand how the MEL1 gene product is responsible for these effects requires analysis of the changes of the transcriptome. The mel1 gene was identified by TOS 17 insertion mutagenesis of Oryza sativa Japonica, cultivar Nipponbare. The TOS 17 insertion line of mel1 and the wild-type parent were the sources of RNA. RNA was extracted from rice panicle (3 cM) of rice grown under natural conditions in rice fields. Small RNAs associated with MEL1 and small RNAs in total RNA were sequenced by Illumina GAII.

Physcomitrella patensTranscriptome or Gene expression

Project description:We used heat shock (HS) treatments and high-throughput mRNA sequencing to obtain HS transcriptomes in the moss Physcomitrella patens. Besides revealing differential gene expression at the transcriptional level, a transcriptome survey identified abundant AS events in the single-cellâtype, undifferentiated, moss protonemal cell. For preparing RNA-seq samples, protonemal colonies were grown at 38Â°C for 1 h (1st HS), recovered at 25Â°C for 5.5 h, and then grown at 38Â°C again for 1 h (2nd HS). Cells remaining at 25Â°C were collected as the control. Note: All samples in SRA were assigned the same sample accession (SRS402930). This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Transcriptional profiling during OSH1 induction

Project description:In flowering plants, knotted1-like homeobox (KNOX) transcription factors play crucial roles in establishment and maintenance of the shoot apical meristem (SAM), from which aerial organs such as leaves, stems and flowers initiate. We report that a rice (Oryza Sativa) KNOX gene Oryza sativa homeobox1 (OSH1) represses the brassinosteroid (BR) phytohormone pathway through activation of BR catabolism genes. Inducible overexpression of OSH1 caused brassinosteroid insensitivity, whereas loss-of-function showed a BR-overproduction phenotype. Genome-wide identification of loci bound and regulated by OSH1 revealed hormonal and transcriptional regulation as the major function of OSH1. Among these targets, BR catabolism genes CYP734A2, CYP734A4 and CYP734A6 were rapidly up-regulated by OSH1-induction. Furthermore, RNAi knockdown plants of CYP734A genes arrested growth of the SAM and mimicked some osh1 phenotypes. Thus, we suggest that local control of BR levels by KNOX genes is a key regulatory step in SAM function.
