Combined analysis of ATAC-Seq and RNA-Seq reveal a potential role of WRKY34 in tomato response to cold stress [ATAC]

ABSTRACT: To further clarify the differences in the potential regulatory mechanisms of cold tolerance between wild and cultivated tomatoes, we subjected cold-sensitive cultivated tomato (Solanum lycopersicum) Ailsa Craig (AC) and cold-tolerant wild tomato (S. habrochaites) LA1777 to cold stress for 6 h, and performed ATAC-Seq and RNA-Seq, respectively.

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).

Methylketone Biosynthesis in Tomato F2 Segregant Populations

Project description:Genetic analysis of interspecific populations derived from crosses between the wild tomato species Solanum habrochaites f glabratum, which synthesizes and accumulates insecticidal methylketones (MKs) such as 2-undecanone and 2-tridecanone in glandular trichomes, and Solanum lycopersicum (cultivated tomato), which does not, demonstrated that MK metabolism in the wild species can be attributed to several loci. Comparative trascriptome analysis of the glandular trichomes of F2 segregants bulked into low- and high-MK plants identified several genes whose transcripts were either more or less abundant in the high-MK plants.

Tomato phototropin1 fruit proteome

Project description:Tomato phototropin1 mutant exhibits deep red color in the ripe fruits compared to the wild type. However, the mechanisms governing this intense fruit coloration in the mutant are largely unknown. Therefore, a proteomic approach combined with carotenoid profiling and carotenogenic gene expression was used to decipher the carotenogenesis in a tomato phototropin1 mutant with S. lycopersicum, cv. Ailsa Craig (tomato).

Comparative RNA-Seq analysis reveals potentially resistance-related genes in response to Bacterial canker of tomato

Project description:Tomato is one of the most important crops for human consumption. Unfortunately, its production is affected by diseases caused by pathogens such as the actynomicete Clavibacter michiganensis subsp. michiganens (Cmm). This pathogen is the causal agent of the bacterial canker of tomato, considered one of the most devastating tomato diseases. To date, there are not resistant varieties of commercial tomato against Cmm. However, there are wild tomato species resistant to Cmm. Using massive sequencing, we obtained the transcriptomes of the wild tomato species Solanum arcanum LA2157 and the commercial tomato Solanum lycopersicum cv. Ailsa Craig at 8 and 24 hours after Cmm challenge. We identified potential tomato tolerance-related genes by three approaches: mapping the reads to S. lycopersicum reference genome SL3.0, performing a semi de novo transcriptome assembly and a de novo transcriptome assembly. Some functional groups such as oxylipin biosynthetic process response to wounding, response to cytokinin among others, were enriched in both tomato species, suggesting a similar response, however, genes that encode proteins such as the Polyphenol oxidase E, Ankyrin and Leucine Rich Repeat receptors were overexpressed mainly in the wild tomato species, suggesting a possible role in the defense response. Here, we uncovered new candidate genes potentially related to bacterial canker tomato defense.

Microarray analysis of ripening tomato fruits with RNAi knockdown of a direct RIN-target GRAS family gene

Project description:The tomato (Solanum lycopersicum) MADS-box transcription factor RIPENING INHIBITOR (RIN) acts as a master regulator of tomato fruit ripening. We previously identified a direct RIN target gene Solyc07g052960, which encodes a putative GRAS family protein belonging to the SHORT-ROOT (SHR) branch, but its role was unknown. RNA interference (RNAi)-mediated gene silencing reduced Solyc07g052960 expression in transgenic fruits, but the fruits appeared to ripen normally. However, the transgenic fruits at the ripening stage showed a marked decrease of the expression levels of several ripening-induced genes, especially involved in cell wall modification and secondary metabolism. This suggests that Solyc07g052960 participates in the regulation of these processes as one component of the RIN-activated transcriptional cascade regulating fruit ripening in tomato. For a preliminary screening, we monitored global gene expression in tomato fruits from untransformed control (Ailsa Craig [AC] cultivar) and three transgenic lines with Solyc07g052960 knockdown by RNAi (lines T-7, T-22 and T-23) at the ripening (pink coloring) stage using microarray without biological replication.

Transcript profiling of tomato mutants producing anthocyanins in the fruit

Project description:Anthocyanins are high value plant antioxidants which are not present in the fruits of cultivated tomato. However, both the dominant gene Anthocyanin fruit (Aft) and the recessive gene atroviolacea (atv), introgressed into domesticated tomato from two different wild Solanum species, stimulate a limited anthocyanin pigmentation. Surprisingly, double mutant Aft/Aft atv/atv tomatoes are characterised by the presence of anthocyanins in the fruit peel, resulting in intensely purple pigmented fruit. We carried out a transcript profiling analysis using GeneChip® Tomato Genome Arrays, in order to identify differentially expressed genes when comparing wild type, Aft/Aft, atv/atv, and Aft/Aft atv/atv fruits. The expression pattern of several genes involved in the anthocyanin pathway was analyzed in detail. Among the fruit peel-associated differentially expressed transcripts, genes involved in phenylpropanoid pathway, cell wall composition, biotic and abiotic stress responses, sugar and hormone metabolism were overrepresented in Aft/Aft atv/atv. Transcriptomic analysis thus revealed that the activation of anthocyanin synthesis in tomato fruit was accompanied by a complex remodulation of gene expression, likely affecting important agronomic and merceological traits. Wild type (Cv. Ailsa Craig, accession number LA2838A), Aft/Aft (accession number LA1996), atv/atv (accession number LA0797) and double mutant (Aft/Aft atv/atv) were grown during the winter season in a controlled heated greenhouse. Fruits were collected at mature green, turning red and red stages of development. The transcriptional profile in Aft/Aft, atv/atv, and Aft/Aft atv/atv fruits when compared to the wild type was analyzed using the GeneChip® Tomato Genome Array.
