Phloem tissue specific genome-wide open chromatin state in Arabidopsis thaliana.

ABSTRACT: Transformation of undifferentiated stem cells into cells with special functions is central for organismal development. The phloem tissue mediates long-distance transport of energy metabolites along plant bodies and is characterized by an exceptional degree of cellular specialization. How the phloem-specific developmental program is implemented is, however, unknown. Here we reveal that the ubiquitously expressed PHD-finger protein OBERON3 (OBE3) and the phloem-specific SUPPRESSOR OF MAX2 1-LIKE 5 (SMXL5) protein form a central module for establishing phloem identity in Arabidopsis thaliana (Arabidopsis). By phloem-specific ATAC-seq analyses, we show that OBE3 and SMXL5 proteins establish a phloem-specific chromatin profile.

Transcription profiling of Arabidopsis phloem

Project description:This sudy focuses on the identification of transcripts in the shoot phloem of the model plant Arabidopsis thaliana. Transcripts expressed in the phloem tissue (parenchyma cell, companion cell, sieve element) were excised by laser microdissection pressure catapulting (LMPC). These were compared with transcripts isolated from leaf phloem exudates by EDTA-chelation technique. Optimization of sample harvest resulted in RNA of high quality from both sources. Modifications of the RNA amplification procedure obtained RNA of sufficient yield and quality for microarray experiments. Microarrays (Affymetrix, ATH1) hybridized with RNA derived from phloem tissue by LMPC or phloem sap allowed us to differentiate between phloem located and mobile transcript species. The datasets provide a search criterion for phloem-based signals and will facilitate reverse genetic studies and forward genetic screens for phloem and long distance RNA signaling mutants. Experiment Overall Design: Arabidopsis plants were cultivated under short day conditions (8 h light) until flowering. Phloem tissue was isolated by Lasermicrodissection and Pressure Catapulting (LMPC) and phloem exudate by EDTA-chelation technique. In both experiments poly-A-RNA was extracted and amplified before hybridization of microarrays (Affymetrix, ATH1). For both experiments three LMPC-derived phloem tissue (LMPC-derived phloem_1-3) and three phloem exudate samples (Phloem exudate_1-3) were analysed. Precise protocols of plant growth, sample harvest, RNA extraction and amplification are provided in Deeken et al., 2008.

Phloem-specific transcriptome profiling links gene expression, physiological characterization with phloem function in the pedicle and fruit of cucumber (Cucumis sativus L.)

Project description:Phloem is essential for higher plant development and survival by transporting photosynthetic products and systemic signals from source to sink organs. To date, most phloem studies were performed with the phloem exudate for physiological, transcriptomic or proteomic analyses. However, as yet, no transcriptomic profiling was performed to the phloem tissue itself, probably due to the technique difficulties to access the phloem tissue inside the plant body. In this study, laser microdissection combined with RNA-Seq technology was used to gain phloem-specific transcript profiling in three different organs (pedicle, stalk and fruit) of cucumber, a model plant species for phloem research. We found that transcription factors and biotic/abiotic stress related genes are highly enriched in the sink organs, while cell growth via calcium ion, hormone actions and cell cycle control was largely restricted in the pedicle and stalk, and genes implicated in transporting amino acids and sugars are mostly up-regulated in the pedicle. Further, we found excellent corroboration between phloem-specific gene expression, and physiological characterization with phloem function. In addition, we identified 432 cucumber-unique genes and several phloem-specific markers for future functional studies. This study provides new insights into the molecular genetics of the function of phloem tissue in cucumber, rather than the conventional phloem sap analyses.

Project description:As a prerequisite for constant growth, plants can produce vascular tissues at different sites in their postembryonic body. In particular, the formation of vascular tissues during longitudinal and radial expansion of growth axes differs fundamentally with respect to its anatomical configuration. This raises the question to which level regulatory mechanisms of vascular tissue formation are shared throughout plant development. Here, we show that, similar as primary phloem formation during longitudinal growth, the cambium-based formation of secondary phloem depends on the function of SMXL genes. Using promoter reporter lines, we observe that SMXL4 and SMXL5 activities are associated with different stages of secondary phloem formation in Arabidopsis stems and that specific loss of SMXL5 function results in the absence of secondary phloem. Interestingly, the additional disruption of SMXL4 activity increases cell proliferation rates in the cambium region without forming secondary phloem. Based on genome-wide transcriptional profiling and expression analyses of phloem-related markers we conclude that early steps of phloem formation are impaired in smxl4;smxl5 double mutants and that additional cambium-derived cells fail in establishing any phloem-related feature. Our results show that molecular mechanisms determining primary and secondary phloem share important features but differ slightly with SMXL5 playing a more dominant role in the formation of secondary phloem.

A molecular circuit that creates the phloem pattern

Project description:The vascular system of plants consists of xylem, phloem and procambium in a specific pattern. The phloem consists of sieve elements, the apparatus for bulk flow of photo-assimilates, and companion cells, which mediate transport of photo-assimilates between the sieve elements and surrounding cells and support the biological activities of the sieve element cells. The regulatory mechanisms of vascular development are being uncovered. Here we show that PHLOEM EARLY DOFs (PEARs) and related genes (collectively phloem-Dofs) not only regulate the number of procambium cell files, but also positively regulate phloem differentiation. Overexpression of phloem-Dofs induced cells that expressed either sieve element or companion cell marker genes, which are mutually exclusive. Conversely, disruption of phloem-Dofs caused loss of phloem. Phloem-Dofs induce CLAVATA3/EMBRYO SURROUNDING REGION-RELATED25 (CLE25) and CLE26 peptides, which in turn inhibit expression of phloem-Dofs and phloem formation, forming a negative feedback loop. Disruption of multiple genes for either phloem-expressed CLEs, BARELY ANY MERISTEM (BAM)-class receptors, or their coreceptors, CLAVATA3 INSENSITIVE RECEPTOR KINASEs (CIKs), caused excess formation of phloem cell files. We further show that phloem-Dofs are under positive self and mutual regulation. These positive and negative feedback loops create the proper phloem pattern.

Tobacco mosaic virus infection alters phloem associated translatomes in Arabidopsis thaliana

Project description:In this study we used vascular specific promoters and a translating ribosome affinity purification strategy to identify phloem-associated translatome responses to infection by tobacco mosaic virus (TMV) in the systemic host Arabidopsis thaliana ecotype Shahdara. Three different promoter:FLAG-RPL18 lines were used. These included two phloem specific promoters (pSUC2 and pSULTR2;2) as well as the more ubiquitously expressed cauliflower mosaic virus 35S promoter (p35S). Immunopurification of ribosome-mRNA complexes was accomplished by the method described in Reynoso et al. (Plant Functional Genomics: Methods and Protocols, 185-207; 2015). The dataset includes samples from the leaves of 5-week-old plants inoculated with TMV (1 mg/mL) or mock inoculated with sterile water.

Transcriptional analysis of phloem-associated cells of potato

Project description:To better understand the function of the phloem in plants, we have combined laser capture microdissection (LCM) and RNA-seq for an in-depth transcriptional profile of phloem-associated cells of both petioles and stems of potato. Out of the 27k transcripts assembled that we identified, approximately 15K were present in phloem-associated cells of petiole and stem with greater than ten reads. Approximately 22% of the transcripts in phloem cells contained at least one binding motif for Pumilio, Nova, or polypyrimidine tract-binding proteins in their downstream sequences. Highlighting the predominance of binding processes identified in the gene ontology analysis of active genes from phloem cells, 78% of the 464 RNA-binding proteins present in the potato genome were detected in our phloem transcriptome. As a reasonable alternative when phloem sap collection is not possible, LCM can be used to isolate RNA from specific cell types, and along with RNA-seq, provides practical access to expression profiles of phloem tissue.

Phloem and non-phloem associated translatomes during plum pox virus infection in Prunus domestica L.

Project description:In this study we used a translating ribosome affinity purification strategy to identify phloem and non-phloem associated translatomes in Prunus domesitca L during PPV infection. Three different promoter:His6FLAG-RPL18 lines were used. These included two phloem specific promoters (pSUC2 and pSULTR2;2) as well as the more ubiquitously expressed cauliflower mosaic virus 35S promoter (p35S). Immunopurification of ribosome-mRNA complexes was accomplished by the method described in Reynoso et al. (Plant Functional Genomics: Methods and Protocols, 185-207; 2015). The dataset includes samples from plum leaves taken at 2, 4, 6, and 12 weeks post cold induced dormancy.
