Plants have evolved a unique plasticity of their root system architecture to flexibly exploit heterogeneously distributed mineral elements from soil. Local high concentrations of nitrate trigger lateral root initiation in adult shoot-borne roots of maize (Zea mays) by increasing the frequency of early divisions of phloem pole pericycle cells. Gene expression profiling revealed that, within 12 h of local high nitrate induction, cell cycle activators (cyclin-dependent kinases and cyclin B) were up ...[more]

RNA-Seq of single cells from the Arabidopsis root

Project description:The definition of cell identity is a central problem in biology. Single-cell RNA-seq provides a wealth of information regarding the developmental state of individual cells. However, better methods are needed to map the identity of single cells, especially during identity transitions. We have developed a quantitative classification method that is robust to expression noise and can detect primary and chimeric identities from single-cell RNA sequencing profiles. The method uses existing transcriptome repositories of grouped cell-types to define a set of optimal cell-identity markers, which are then used to define a cell identity metric. This metric accurately classified diverse cell identities in Arabidopsis root tips and human glioblastoma cells. We demonstrate the strength of the approach to resolve a dynamic developmental process by analyzing the identity of single cells captured from regenerating Arabidopsis roots following removal of their stem-cell-niche. We discover that, apart from new niche formation at the vicinity of the cut site, cells that are distant from the injury site also undergo a transient, partial collapse of identity during the regeneration and reorganization of the root, demonstrating the usefulness of a quantitative cell identity metric. Overall design: 4 Technical replicates (pooled-and-split single QC cells), 23 cells from the QC, 3 cells from the Stele, and 4 cells from the stele, 16h following root tip decapitation

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.

Transcriptome and Metabolite Profiling of the Infection Cycle of Zymoseptoria tritici on Wheat Reveals a Biphasic Interaction with Plant Immunity Involving Differential Pathogen Chromosomal Contributions and a Variation on the Hemibiotrophic Lifestyle Definition.

Project description:The hemibiotrophic fungus Zymoseptoria tritici causes Septoria tritici blotch disease of wheat (Triticum aestivum). Pathogen reproduction on wheat occurs without cell penetration, suggesting that dynamic and intimate intercellular communication occurs between fungus and plant throughout the disease cycle. We used deep RNA sequencing and metabolomics to investigate the physiology of plant and pathogen throughout an asexual reproductive cycle of Z. tritici on wheat leaves. Over 3,000 pathogen genes, more than 7,000 wheat genes, and more than 300 metabolites were differentially regulated. Intriguingly, individual fungal chromosomes contributed unequally to the overall gene expression changes. Early transcriptional down-regulation of putative host defense genes was detected in inoculated leaves. There was little evidence for fungal nutrient acquisition from the plant throughout symptomless colonization by Z. tritici, which may instead be utilizing lipid and fatty acid stores for growth. However, the fungus then subsequently manipulated specific plant carbohydrates, including fructan metabolites, during the switch to necrotrophic growth and reproduction. This switch coincided with increased expression of jasmonic acid biosynthesis genes and large-scale activation of other plant defense responses. Fungal genes encoding putative secondary metabolite clusters and secreted effector proteins were identified with distinct infection phase-specific expression patterns, although functional analysis suggested that many have overlapping/redundant functions in virulence. The pathogenic lifestyle of Z. tritici on wheat revealed through this study, involving initial defense suppression by a slow-growing extracellular and nutritionally limited pathogen followed by defense (hyper) activation during reproduction, reveals a subtle modification of the conceptual definition of hemibiotrophic plant infection.
