Project description:The occurrence of Tomato chlorosis virus (ToCV) disease seriously damages tomato growth and yield, and there is no effective way to control ToCV transmission. So far, no studies have reported exploring the interaction between ToCV and tomato at the single cellular level. In this study, single cell RNA sequence was performed on a total of 26720 individual cells from healthy and ToCV-infected tomato leaves. We through identifying cell types, the first tomato leaf cell atlas was successfully constructed. In situ hybridization experiments identified specific marker genes that can be used to identify tomato cell types. Moreover, we have characterized transcription factors that may play a key role in tomato response to ToCV infection, and described the trichome differentiation trajectory during ToCV infection through pseudotime analysis. In conclusion, we proved the feasibility of single-cell sequencing to study the response of plants to biotic stress, and put forward new insights into the interaction between ToCV and tomato from the cellular level. Our data will lay the foundation for following studies between ToCV and plants, and will also provide a valuable reference for future research on non-model plant single cells.

Project description:In order to identify targets of the transcription factor AUXIN RESPONSE FACTOR5 / MONOPTEROS (ARF5/MP), we compared transcriptomes of mp-B4149 mutant seedlings (9 day-old) and seedlings carrying the dexamethasone-inducible version of the MP inhibitor protein BODENLOS (GR-bdl). Without dexamethasone (DEX) treatment, this line is identical to the wild-type, while DEX treatment leads to strong inhibition of ARF-dependent transcription. To remove all endogenous MP-inhibiting Aux/IAA proteins, we treated mp or GR-bdl seedlings during 1 hour with auxin (50 micromolar Indole-3-Acetic Acid), either with or without a pretreatment with 10 micromolar DEX for 1 hour. Genes that are activated by MP are expected to br downregulated in mp seedlings and in the GR-bdl line afer DEX treatment. We used biological duplicates for each of the three treatments. Keywords: Transcriptional profiling of transcription factor targets

Keywords: Transcriptional profiling of transcription factor targets Mp mutant and GR-bdl seeds were germinated on solid 1/2MS media, and transferred to liquid medium after 9 days of horizontal growth. Duplicate cultures were generated for mp mutants, and quadruplicates for the GR-bdl line. 10 micromolar DEX was added to both mp cultures and to two of the GR-bdl cultures, and seedlings were gently shaken during 1 hour. Then, 50 micromolar IAA was added to all 6 cultures and seedlings were incubated with gentle shaking for another hour. Total RNA was isolated from the seedlings using a QIAgen RNeasy kit, and reverse transcription, in-vitro transcription, cRNA labling and fragemntation was done according to established methods (Schmid et al., Nature Genetics [2005] 37, 501-506). Labeled cRNA was hybridized to Arabidopsis ATH1 arrays.

The array was designed to include all the known tomato genes retrieved from TIGR and Sol Genomics public databases. Following filtration for redundancies, 25,591 known genes and 7,335 uncertain or unknown genes were retrieved The data were transferred to Roche NimblGen company (http://www.nimblegen.com/) who has generated a 60-mer oligonucleotide array where each of the ~30,000 tomato genes is represented by at least two specific probes, and unrelated controls. Each slide contains four arrays of ~70,000 oligos. TYLCV resistant and susceptible lines infection with TYLCV and LeHT1 silenced TYLCV resistant line infected with TYLCV

Project description:The targets of AUXIN REPONSE FACTOR5/MONOPTEROS (ARF5/MP) were reported in many studies which mainly concerned to the flower initiation. But most of these targets are expressed in periphery zone (PZ), how MP regulate the stem-cell activity is unclear. In order to specifically identify the targets of MP in stem cells, as clv3 mutant enrich lots of stem cells, thus we performed transcriptomes of clv3 and mpclv3. This method will enhance the resolution of MP targets specific in stem cells. And it will also avoid the severe morphologic difference between WT and mp single mutant.

Project description:In order to find the specific promoter of tomato exocarp, we extracted RNA extraction from the red ripe exocarp, red ripe mesocarp, mature green exocarp, mature green exocarp and leaf cells, and then performed RNA seq to find the differential genes from the Transcriptome data. Our data provides gene expression data for three tissues of tomato during the red ripe and mature green stages, laying the foundation for the search for differential genes

Project description:Gene-to-gene coexpression analysis is a powerful approach to infer function of uncharacterized genes. To perform non-targeted coexpression analysis of tomato genes, we collected a developmental gene expression dataset using various tissues of tomato plant. Expression data are collected from 24 different tissue types including root, hypocotyl, cotyledon, leaf at different stages, and fruit tissues at 4 different ripening stages from 4 different Solanum lycopersicum cultivars. Fruits were separated to the flesh and the peel. These two tissue types indeed showed remarkably different gene expression profiles. We also collected data from 4 different ripening stages (mature green, yellow, orange, and red) to detail the changes during ripening. By using this gene expression dataset, we calculated pair-wise Pearson’s correlation coefficients, and performed network-based coexpression analysis. The analysis generated a number of coexpression modules, some of which showed an enrichment of genes associated with specific functional categories. This result will be useful in inferring functions of uncharacterized tomato genes, and in prioritizing genes for further experimental analysis. We used Affymetrix GeneChip Tomato genome Arrays to detail the global gene expression change using 24 different tomato tissue types (67 hybridizations).
