Project description:The aim of this study was to compare the tomato global transcriptional profiles in response to host attack by ToMV and Fol in order to identify genomic differences and similarities in incompatible interactions between a foliar and a vascular pathogen. In order to identify a set of genes of interest in tomato plants infected with F. oxysporum f. sp. lycopersici (Fol) and Tomato Mosaic Virus (ToMV) a transcriptional analysis was performed. Tomato genes differentially expressed upon inoculation with Fol and ToMV were identified at 2 days post-inoculation, using an un-inoculated sample as reference.

Project description:Pepino Mosaic Virus (PepMV) consists a major pathogenic threat in the greenhouses worldwide and has a devasting impact on tomato global production. PepMV belongs to the Potexvirus genus of the Flexiviridae family. PepMV has a viral RNA genome of approximately 6400 nucleotides long that contains five open reading frames (ORFs) and 4 major genotypes have been characterized. TomCr3, an indigenous virulent PepMV strain derived from the Chilean (CH2) genotype, was isolated in Crete, Greece and was used for the mechanical infection of Belladonna F1 hybrid tomato seedlings. Here, we present the results of a deep RNA-sequencing (RNA-seq) analysis performed to characterize the dynamic expression profile of tomato genes upon PepMV infection, including tomato transcription factors.

Project description:Tomato seeds (S. lycopersicum ‘Fl Lanai’) were germinated under greenhouse conditions maintained at 24°C-29°C in flat trays (BWI Apopka, Catalog Number GPPF72S7X) filled with Sungro Horticulture soil (Metro-mix 830, BWI Apopka, Cat# TX830). Two weeks post emergence seedlings were transplanted to 4” pots using the same soil and transferred to a Conviron walk-in growth chamber (CMP6060) for the remainder of the experiment. Conviron conditions include a 14h/10h light/dark cycle maintained at 28°C, and plants were fertilized weekly (20-20-20). To prevent cross contamination, tomato plants were confined to insect proof cages at all times (BioQuip 1450NS68). Four weeks after transplanting, 40 whiteflies (B. tabaci MEAM1) were collected from virus free or Tomato Mottle Virus (ToMoV) established colonies via aspiration and moved into a clip cage placed on the 4th true leaf of each tomato plant as previously described38. Whiteflies were reared cabbage (Brassica oleracea), while viruliferous whiteflies were reared on ToMoV infected tomato from colonies established in the Polston lab. For all plants in this study, feeding was halted after 3 days of whitefly feeding (3 DPI) by gentle removal of clip cages and whitefly termination using insecticidal soap (Garden Safe, 1% of potassium salts of fatty acids). For the samples referred to as “local”, the tomato leaf bound within the clip cages was immediately removed and snap frozen for protein extraction. For the samples designated “systemic”, the plants were allowed to continue growing for 7 additional days after clip cage removal and whitefly termination, at which point the 9th leaf was excised and snap frozen. Plants used for collection of local leaves at 3 DPI were not used for the collection of systemic leaves 10 DPI. For both local and systemic leaves collected, we also included a no treatment control (NTC) that was subjected identically to clip cage and insecticidal soap applications, but without the addition of whitefly or ToMoV. Our experiment therefore consists of a no-treatment control (NTC), a whitefly treatment (+WF), and a viruliferous whitefly (+WFV) treatment for both local (4th true leaf, 3 DPI) and systemic leaves (9th true leaf, 10 DPI). The presence of ToMoV in all infected plants was confirmed via Nanopore sequencing. Briefly, Tomato genomic DNA was extracted from five systemic leaf samples using the PureGene tissue DNA isolation kit (product # 158667; QIAGEN, Valencia, CA, USA), following the manufacturer’s protocol and stored at -80°C until needed. Library preparation was performed using the Rapid Sequencing Kit RBK004 protocol (Oxford Nanopore Technologies) and loaded onto a 9.4.1 flow cell in a MinION connected to a MinIT with live base calling enabled. Resulting sequencing reads for each sample were mapped to both ToMoV A component (GenBank accession: L14460) and ToMoV B component (GenBank accession: L14461) sequences.

Project description:We constructed two independent small RNA libraries from leaves of mock and Cucumber mosaic virus (CMV) infected tomatoes, respectively, and sequenced with a high-throughput Illumina Solexa system. Based on sequence analysis and hairpin structure prediction, a total of 50 known miRNAs (32 families) and 568 potentially candidate miRNAs (PC-miRNAs) were firstly identified in tomato, with 12 known miRNAs and 154 PC-miRNAs supported by both the 3p and 5p strands. Comparative analysis revealed 79 miRNAs (including 15 novel tomato miRNAs) and 40 PC-miRNAs were differentially expressed between the two libraries. Among these virus responsive miRNAs, expression patters of some novel tomato miRNAs and PC-miRNAs in mock and in CMV-Fny infected tomatoes were further validated by qRT-PCR. Moreover, we revealed 563 potential targets for 66 tomato miRNAs by the recently developed degradome sequencing approach, including 124 targets for 7 new tomato miRNAs and 97 targets for 24 PC-miRNAs. Target annotation for the newly identified miRNA and PC-miRNAs indicated that they were involved in multiple biological processes, including transcriptional regulation and virus resistance. Gene ontology analysis of these target transcripts demonstrated that stress response- and photosynthesis-related genes were most affected in CMV-Fny infected tomatoes.

Project description:Chinese soybean (Glycine max (L.) Merr.) cultivars Rsmv1 and Ssmv1 were used for soybean mosaic virus (SMV) resistance genes screening. The Rsmv1 cultivar was highly-resistant to SMV but the Ssmv1 cultivar was highly-susceptible. We used microarrays to detail the global programme of gene expression underlying SMV inoculation and identified distinct expression genes between Rsmv1 and Ssmv1.
