Atlas of chromatin accessibility and translatome of tomato and rice root tip cell types

ABSTRACT: Plant species have evolved specialized cell types and regulatory programs. To understand this diversity, we profiled tomato cell type translatomes and chromatin accessibility. While cell type expression signatures are diverse, some genes exhibit robust cell type expression across time and environments. Using xylem differentiation as a model, newly described, repurposed and conserved genes illustrate this spatial variation. Data integration into regulatory networks demonstrates the function of molecularly uncharacterized cell types. Analyses of rice, tomato and Arabidopsis tissues suggest that root meristems are more conserved, while other cell types/tissues exhibit species-specific genes and processes. Several transcriptional properties observed in animals were also observed in plants and suggest cross-kingdom higher-order organizational properties. These data serve as a community resource, paving the way for engineering resilient crops.

NIMH Human Middle Temporal Gyrus (MTG) Cell Types

Project description:<p>Elucidating the cellular architecture of the human neocortex is central to understanding our cognitive abilities and susceptibility to disease. In this study, we applied single nucleus RNA sequencing to perform a comprehensive analysis of cell types in the middle temporal gyrus of human cerebral cortex. We identify a highly diverse set of excitatory and inhibitory neuronal types, many of which are relatively sparse. Additionally, we found that excitatory types are less layer-restricted than expected based prior knowledge from cell morphologies and from mouse studies. Comparison to a similar mouse cortex single cell RNA-sequencing dataset revealed a surprisingly well-conserved cellular architecture that enables matching of homologous types and predictions of human cell type properties. Despite this general conservation, we also find extensive differences between homologous cell types in human and mouse, including dramatic alterations in proportions, laminar distributions, gene expression, and morphology. These species-specific features emphasize the importance of directly studying human brain.</p> <p>This study conducted by the Allen Institute for Brain Science was supported by the Allen Institute for Brain Science and by US National Institutes of Health grant U01 MH114812-02 to E.S.L.

A glial circadian gene expression atlas reveals cell type and disease-specific reprogramming in response to amyloid pathology or aging

Project description:While circadian rhythm disruption may promote neurodegenerative disease, how aging and neurodegenerative pathology impact circadian gene expression patterns in different brain cell types is unknown. Here, we used translating ribosome affinity purification methods to define the circadian translatomes of astrocytes, microglia, and bulk cerebral cortex, in healthy mouse brain and in the settings of amyloid-beta plaque pathology or aging. Our data reveal that glial circadian translatomes are highly cell type-specific and exhibit profound, context-dependent reprogramming of rhythmic transcripts in response to amyloid pathology or aging. Transcripts involved in glial activation, immunometabolism, and proteostasis, as well as nearly half of all Alzheimer Disease (AD)-associated risk genes, displayed circadian oscillations, many of which were altered by pathology. Amyloid-related differential gene expression was also dependent on time of day. Thus, circadian rhythms in gene expression are cell- and context dependent and provide important insights into glial gene regulation in health, AD, and aging.

ATAC-seq profiling of open chromatin in the root tips of four plant species (Arabidopsis thaliana, Medicago truncatula, Solanum lycopersicum, and Oryza sativa) and two Arabidopsis thaliana cell types (root hair and non-hair epidermal cells)

Project description:The transcriptional regulatory structure of plant genomes remains poorly defined relative to that of animals. It has been unclear how many cis-regulatory elements generally exist in plant genomes, where these elements lie in relation to their target promoters, and how these features are conserved across species. We employed the Assay for Transposase-Accessible Chromatin with sequencing (ATAC-seq) in four different plant species (Arabidopsis thaliana, Medicago truncatula, Solanum lycopersicum, and Oryza sativa) to delineate open chromatin regions and transcription factor (TF) binding sites across each genome. Despite a ~10-fold variation in intergenic space among species, the majority of open chromatin regions consistently lie within 3 kb upstream of a transcription start site (TSS) in all four species. Nearly 70% of genes in Arabidopsis, Medicago, and Rice have a single putative regulatory region upstream of the TSS, while a similar percentage of tomato genes have 2-5 such elements. Despite variation in the location and number of regulatory elements within orthologous gene sets, transcriptional regulatory networks appear to be largely conserved across species. Profiling of open chromatin in the Arabidopsis root hair and non-hair epidermal cell types indicated that while the open chromatin landscapes of these two cell types were largely indistinguishable on a global scale, thousands of relatively subtle, quantitative cell-specific differences could be found. Analysis of TF binding sites in these differentially accessible regions led to the discovery of a MYB-driven transcriptional regulatory module unique to the hair cell type, which appears to control both hair cell fate regulators and abiotic stress responses. Our cross-species and cross-cell type analyses revealed common transcriptional regulatory principles among species and shed light on the mechanisms that produce cell type-specific transcriptomes during development.

Conserved pleiotropy of an ancient plant homeobox gene uncovered by cis-regulatory dissection

Project description:Divergence of gene function is a hallmark of evolution, but assessing functional divergence over deep time is not trivial. The few alleles available for cross-species studies often fail to expose the entire functional spectrum of genes, potentially obscuring deeply conserved pleiotropic roles. Here, we explore the functional divergence of WUSCHEL HOMEOBOX9 (WOX9), suggested to have species-specific roles in embryo and inflorescence development. Using a cis-regulatory editing drive system, we generated a comprehensive allelic series in tomato, which revealed hidden pleiotropic roles for WOX9. Analysis of accessible chromatin and conserved cis-regulatory sequences identified the regions responsible for this pleiotropic activity, the functions of which were conserved in groundcherry, a tomato relative. Mimicking these alleles in arabidopsis, distantly related to tomato and groundcherry, revealed new inflorescence phenotypes, exposing a deeply conserved pleiotropy. We suggest that targeted cis-regulatory mutations can uncover conserved gene functions and reduce undesirable effects in crop improvement.

A novel viral tool designed with enhancer-driven gene expression (EDGE) technology allows specific labelling of cell types in wild type rodents

Project description:The mammalian brain contains an unimaginable number of neurons, who are all intricately connected to form complex neuronal circuits. Neurons that exhibit similar properties are often defined as belonging to the same cell-type, which can be determined for example by analysing the genetic profile of the cells. A key aspect of studying brain function on a circuit level is the ability to target specific cell types, but this necessitates sophisticated molecular and genetic tools. Here, we contribute to the ever-expanding toolkit of genetic targeting approaches, by utilizing Enhancer-Driven Gene Expression (EDGE) technology to create viral tools that allow specific targeting of cell populations in the hippocampus and parahippocampus of wild type mice. We also demonstrate the applicability of our tool in wild type rats, emphasising the versatility of this technology in cross-species studies. Cell-type specific targeting in wild type animals is something that could be of great benefit to the field, also in other species than mice where transgenic lines are not common.

Identification and comparison of orthologous cell types from primate embryoid bodies shows limits of marker gene transferability

Project description:The foundation of many human-specific traits is likely established during early embryonic development. To understand these molecular processes, we compared gene expression dynamics in embryoid bodies (EBs) differentiated from iPSCs of four primate species: human, orangutan, cynomolgus, and rhesus macaque. We performed scRNA-seq on ∼ 85,000 cells after 8 and 16 days of EB differentiation, identifying diverse cell types across all three germ layers. To accurately compare cell types across species, we developed a semi-automated computational pipeline combining classification and label transfer across clusters to identify orthologous cell types. This approach allowed us to investigate cross-species reproducibility of marker genes, revealing that human markers were less effective in macaques, and vice versa. We found transcription factors to be the most conserved markers, highlighting their potential for cross-species studies. Overall, our study enhances the understanding of conserved and diverged molecular features in early primate development and we provide a well curated cell type reference for future in vitro studies using primates.

Quantitative Analysis of Transcription Dynamics in Pluripotent and Differentiated Cells

Project description:Cellular identity is a direct consequence of the transcriptional output for any given cell type. Understanding the regulatory properties of the genes that define each cell type is of fundamental importance. In this study, we performed a detailed characterization of the gene expression profiles in embryonic stem cells (ESC) and three terminally differentiated primary cell types. Using deep chromatin RNA sequencing (~500 million mapped reads), we were able to accurately quantify transcripts for genes expressed at very low levels. This provides us with the ability to distinguish genes that exhibit a broad dynamic range among cell types from those whose dynamic range of expression is more limited.

The gray phenotype in the human fungal pathogen Candida tropicalis

Project description:Phenotypic plasticity, the ability to switch between different morphological types, plays critical roles in environmental adaptation, leading to infections, and allowing for sexual reproduction in pathogenic Candida species. Candida tropicalis, which is both an emerging human fungal pathogen and an environmental fungus, can switch between two heritable cell types termed white and opaque. In this study, we report the discovery of a novel phenotype in C. tropicalis, named the gray phenotype. Similar to Candida albicans and Candida dubliniensis, white, gray, and opaque cell types of C. tropicalis also form a tristable switching system, where gray cells are relatively small and elongated. In C. tropicalis, gray cells exhibit intermediate levels of mating competency and virulence in a mouse systemic infection model compared to the white and opaque cell types, express a set of cell type-enriched genes, and exhibit both common and species-specific biological features. The key regulators of white-opaque transitions, Wor1 and Efg1, are not required for the gray phenotype. A comparative study of the gray phenotypes in C. tropicalis, C. albicans, and C. dubliniensis provides clues to explain the species differences in terms of virulence, ecological niches, and prevalence among these three species.

Tomato clade proteome - Green-fruited Solanum habrochaites lacks fruit-specific carotenogenesis due to metabolic and structural blocks

Project description:Members of the tomato clade exhibit wide diversity in fruit coloration, growth habit, leaf morphology and mating preferences. However, the mechanisms governing inter-species diversity in fruit coloration are largely unknown. Therefore, a proteomic approach combined with carotenoid profiling and carotenogenic gene expression was used to decipher the diversity in carotenogenesis in green-fruited Solanum habrochaites, orange-fruited S. galapagense, and red-fruited S. pimpinellifolium with S. lycopersicum, cv. Ailsa Craig (tomato).
