High-throughput single-cell transcriptome profiling of plant cell types

ABSTRACT: Single-cell transcriptome analysis of heterogeneous tissues can provide high-resolution windows into the spatiotemporal dynamics of developmental processes and environmental responses. Here we use the high-hroughput Drop-seq approach to profile the transcriptomes of over 12,000 individual cells from the Arabidopsis root. We identify marker genes for a diversity of cell types, capture cell-type frequency and gene expression alterations in response to sucrose, and illuminate the transcriptome changes that occur across endodermis development.

High-throughput single cell transcriptome profiling of plant tissue

Project description:Plant tissues are composed of diverse cell populations, but their individual transcriptional profiles are not well characterized. High-throughput single cell RNA sequencing technologies can deconvolute heterogeneous tissues but have not been adopted for plants. Exploiting Arabidopsis root protoplasts as a model, we used Drop-seq to profile >4,000 individual plant cells, capturing a diversity of cell types, identifying novel marker genes, and illuminating developmental trajectories of endodermis and hair cells.

Rapid and Pervasive Changes in Genome-Wide Enhancer Usage During Mammalian Development

Project description:Here we used epigenomic profiling for H3K27ac, a mark of active enhancers to examine the genome-wide in vivo utilization of enhancers in three different mouse tissues across seven developmental stages, ranging from mid-gestation through adulthood. The majority of the ~90,000 enhancers identified exhibited tightly temporally restricted activity windows and were associated with stage-specific biological functions and regulatory pathways in individual tissues. Comparative genomic analysis revealed that evolutionary conservation of enhancers decreases following mid-gestation across all tissues examined. The dynamic enhancer activities uncovered in this study illuminate rapid and pervasive temporal in vivo changes in enhancer usage underlying developmental processes and demonstrate the value of time-course chromatin profiling of relevant tissues across development. Examination of H3K27ac in mouse forebrain, heart and liver tissues collected across developmental stages.

Comprehensive gene expression profiling of the rice root system based on developmental stages and tissue types

Project description:The root system is a crucial determinant of plant growth potential because of its important functions, e.g., acquisition of water and nutrients, structural support, and interaction with symbiotic organisms. Elucidating the molecular mechanisms of root development and functions is therefore necessary for improving plant productivity, particularly for crop plants including rice. As an initial step towards developing a comprehensive understanding of the root system, we performed a large-scale transcriptome analysis of the rice root via a combined laser microdissection and microarray analysis approach. We performed comprehensive microarray analysis of a rice crown root using laser microdissection and collected a total of 13 samples (3 replicates for each sample except for one sample, 38 total microarray data) representing 8 different developmental stages along the longitudinal axis and 3 distinct tissue-types along the radial axis at 2 different developmental stages. The 8 developmental stages represent root cap, division zone, elongation zone and maturation zone_I, II, III, IV and V. The 3 tissue-types represent epidermis/exodermis/sclerenchyma, cortex, and endodermis/pericycle/stele. In the maturation zone_V, the cortex consisted largely of aerenchyma (non-living cells) and was not used for the microarray analysis.

MYB36 regulates the transition from proliferation to differentiation in the Arabidopsis root

Project description:Stem cells are defined by their ability to self-renew and produce daughter cells that proliferate and mature. These maturing cells transition from a proliferative state to a terminal state through the process of differentiation. In the Arabidopsis thaliana root the transcription factors SCARECROW and SHORTROOT regulate specification of the bi-potent stem cell that gives rise to the cortical and endodermal progenitors. Subsequent progenitor proliferation and differentiation generates mature endodermis, marked by the Casparian Strip: a cell wall modification that prevents ion diffusion into and out of the vasculature. We identified a transcription factor, MYB36 that regulates the transition from proliferation to differentiation in the endodermis. We show that SCARECROW directly activates MYB36 expression, which in turn directly regulates essential Casparian Strip formation genes. In addition, MYB36 represses extra divisions within the endodermis. Our results demonstrate that MYB36 is a critical positive regulator of differentiation and negative regulator of cell proliferation. 12 samples analyzed: 3 biological replicates each from 1) wild type (Col-0) whole root, 2) mutant (myb36-1) whole root, 3) wild type (Col-0) sorted endodermis, 4) mutant (myb36-1) sorted endodermis

Endodermis-specific Receptor-like Kinase (ERK1) is required for the deposition of lignin in the Casparian strip in the root

Project description:The Casparian strip constitutes a physical diffusion barrier formed by the polar deposition of lignin in the root endodermis. The polar deposition of lignin is thought to be mediated by the scaffolding activity of membrane bound Casparian Strip domain proteins (CASPs) and the dirigent domain-containing protein Enhanced Suberin1 (ESB1). Here, we show that the endodermis-specific receptor-like kinase (ERK1), is part of this machinery, playing an essential role in the localization of CASP proteins and in the deposition of lignin, which ultimately are required for the formation of afunctional Casparian strip. ERK1 is localized to the cytoplasm and nucleus of the endodermis, and is part of a signalling pathway that implicates the circadian clock regulator Time for Coffee (TIC). In addition, we found that loss of ERK1 and TIC disrupts the Casparian strip organisation and alters composition of the root microbiome.

Expression data from epidermis specific phytochrome B or global phytochrome B line comparing to phyB-9 mutant.

Project description:Seedling hypocotyls display negative gravitropism in the dark but agravitropism in the light. The Arabidopsis thaliana pif quadruple mutant (pifQ), which lacks four PHYTOCHROME-INTERACTING FACTORS (PIFs), is agravitropic in the dark. Endodermis-specific expression of PIF1 rescues gravitropism in pifQ mutant seedlings. Since phytochromes induce light responses by inhibiting PIFs and the COP1-SPA ubiquitin E3 ligase complex in the nucleus, we asked whether phyB can cell autonomously inhibit hypocotyl negative gravitropism in the endodermis. We found that while epidermis-specific expression of PHYB rescues hypocotyl negative gravitropism and all other phyB mutant phenotypes, endodermis-specific expression of PHYB does not. Epidermal phyB induces the phosphorylation and degradation of endodermal PIFs in response to red light. This induces a global gene expression pattern similar to that induced by red light treatment of seedlings expressing PHYB under the control of its own endogenous promoter. Our results imply that epidermal phyB generates an unidentified mobile signal that travels to the endodermis where it promotes PIF degradation and inhibits hypocotyl negative gravitropism.
