Epistatic QTL for yield heterosis in tomato
<p>Controlled population development and genome-wide association studies have proven powerful in uncovering genes and alleles underlying complex traits. An underexplored dimension of such studies is the phenotypic contribution of non-additive interactions between quantitative trait loci (QTL). Capturing such epistasis in a genome-wide manner requires very large populations to represent replicated combinations of loci whose interactions determine phenotypic outcomes. Here, we dissect epistasis using a densely genotyped population of 1400 backcross-inbred lines (BILs) between a modern processing tomato inbred (<em>Solanum lycopersicum</em>) and the Lost Accession of a distant, green-fruited, drought-tolerant wild species, <em>Solanum pennellii</em>. The homozygous BILs, each representing an average of 11 introgressions, and their hybrids with the recurrent parents were phenotyped for tomato yield components. Population-wide mean yield of the BILs was less than 50% of that of their hybrids (BILH), and correspondingly, homozygous introgressions across the genome reduced yield relative to recurrent parent while several QTL of the BILHs independently improved productivity. Analysis of two QTL scans showed 32 cases of less than additive and 48 cases of more than additive interactions. Strikingly, one epistatic interaction involving <em>S. pennellii</em> QTL on chromosomes 1 and 7, which independently did not affect yield, increased fruit yield by 20-50% in the double introgression hybrid grown in irrigated and dry fields over a period of three years and varied genetic backgrounds. Our work demonstrates the power of large, interspecific controlled population development to uncover hidden QTL phenotypes, and how rare epistatic interactions can improve crop productivity via heterosis.</p>

Raw data related to: Randomised Clinical Trial: Calorie Restriction Regimen with Tomato Juice Supplementation Ameliorates Oxidative Stress and Preserves a Proper Immune Surveillance Modulating Mitochondrial Bioenergetics of T-Lymphocytes in Obese Children Affected by Non-Alcoholic Fatty Liver Disease (NAFLD)
<p><strong>Abstract</strong></p> <p>Fatty liver disease is a serious complication of childhood obesity. Calorie-restricted regimen (RCR) is one of the e ective therapy for this condition. Aim of the study was to evaluate the effect of lycopene-rich tomato sauce with oregano and basil extracts in obese children with fatty liver on RCR. 61 obese children with fatty liver were enrolled, 52 completed the study. A randomized cross over clinical trial was performed. Participants were assigned to RCR alone or with a supplement of lycopene-rich tomato juice for 60 days; subsequently, the groups were switched to the alternative regimen for the next 60 days. Reduction in BMI, HOMA-IR, cholesterol, triglycerides, liver size, and steatosis was more profound in tomato-supplemented group. Leptin decreased in both groups whereas adiponectin raised only after tomato supplementation. RCR is associated with the impaired engagement of T-cells glycolysis and proliferation, tomato-supplementation resulted in glycolytic metabolic activation of T-cells. Tomato juice ameliorates glucose and lipid metabolism in obese children, improve oxidative and inflammatory state and modulates the mitochondrial metabolism of T-cells contributing to a maintenance of a proper immune surveillance in children, impaired by RCR. The addition of tomato to RCR could be considered a protective and preventive support to obese child.</p> <p><strong>Progetto giovani ricercatori </strong>[GR-2016-02363725] dal titolo: "Immune Tolerance, Metabolism and Multiple Sclerosis: Novel Molecular Tools to Monitor Disease Pathogenesis and Progression"</p>

Modulation of the Tomato Fruit Metabolome by LED Light (GCMS and LCMS datasets)
<p>Metabolic profiles of tomatoes change during ripening and light can modulate the activity of relevant biochemical pathways. We investigated the effects of light directly supplied to the fruits, on the metabolome of the fruit pericarp during ripening. Mature green tomatoes were exposed to well-controlled conditions with light as the only varying factor; control fruits were kept in darkness. In Experiment 1 the fruits were exposed to either white light or darkness for 15 days. In Experiment 2 fruits were exposed to different light spectra (blue, green, red, far-red, white) added to white background light for 7 days. Changes in the global metabolome of the fruit pericarp were monitored using LCMS and GCMS (554 compounds in total). Health-beneficial compounds (carotenoids, flavonoids, tocopherols and phenolic acids) accumulated faster under white light compared to darkness, while alkaloids and chlorophylls decreased faster. Light also changed the levels of taste-related metabolites including glutamate and malate. The light spectrum treatments indicated that the addition of blue light was the most effective treatment in altering the fruit metabolome. We conclude that light during ripening of tomatoes can have various effects on the metabolome and may help shaping the levels of key compounds involved in various fruit quality characteristics.</p>
Regional differences in the abiotic environment contribute to genomic divergence within a wild tomato species
<p>The wild currant tomato <i>Solanum pimpinellifolium </i>inhabits a wide range of abiotic habitats across its native range of Ecuador and Peru. Although it has served as a key genetic resource for the improvement of domestic cultivars, little is known about the genetic basis of traits underlying local adaptation in this species, nor what abiotic variables are most important for driving differentiation. Here we use redundancy analysis (RDA) and other multivariate statistical methods (structural equation modeling (SEM) and generalized dissimilarity modeling (GDM)) to quantify the relationship of genomic variation (6,830 single nucleotide polymorphisms) with climate and geography, among 140 wild accessions. RDA, SEM, and GDM each identified environment as explaining more genomic variation than geography, suggesting that local adaptation to heterogeneous abiotic habitats may be an important source of genetic diversity in this species. Environmental factors describing temporal variation in precipitation and evaporative demand explained the most SNP variation among accessions, indicating that these forces may represent key selective agents. Lastly, by studying how SNP-environment associations vary throughout the genome (44,064 SNPs), we mapped the location and investigated the functions of loci putatively contributing to climatic adaptations. Together our findings indicate an important role for selection imposed by the abiotic environment in driving genomic differentiation between populations. </p>
Data from: Tetranychus evansi spider mite populations suppress tomato defences to varying degrees
<p>Plant defence suppression is an offensive strategy of herbivores, in which they manipulate plant physiological processes to increase their performance. Paradoxically, defence suppression does not always benefit the defence-suppressing herbivores, because lowered plant defences can also enhance the performance of competing herbivores and can expose herbivores to increased predation. Suppression of plant defence may therefore entail considerable ecological costs depending on the presence of competitors and natural enemies in a community. Hence, we hypothesize that the optimal magnitude of suppression differs among locations. To investigate this, we studied defence suppression across populations of Tetranychus evansi spider mites, a herbivore from South America that is an invasive pest of solanaceous plants including cultivated tomato, Solanum lycopersicum, in other parts of the world. We measured the level of expression of defence marker genes in tomato plants after infestation with mites from eleven different T. evansi populations. These populations were chosen across a range of native (South American) and non-native (other continents) environments and from different host plant species. We found significant variation at three out of four defence marker genes, demonstrating that T. evansi populations suppress jasmonic acid- and salicylic acid-dependent plant signalling pathways to varying degrees. While we found no indication that this variation in defence suppression was explained by differences in host plant species, invasive populations tended to suppress plant defence to a smaller extent than native populations. This may reflect either the genetic lineage of T. evansi - as all invasive populations we studied belong to one linage and both native populations to another - or the absence of specialized natural enemies in invasive T. evansi populations.</p>
Tomato Protein Phosphatase 2C (SlPP2C3) influences fruit ripening onset and fruit glossiness
<p><span>Abscisic acid (ABA) plays a vital role in coordinating physiological processes during fresh fruit ripening. ABA can bind to ABA receptors which interacts and inhibits their co-receptors type 2C phosphatases (PP2Cs). However, the dissected mechanism of PP2C during fruit ripening is unclear. In this study, we identify the role of SlPP2C3, a tomato type 2C phosphatase, as a negative regulator of ABA signaling and fruit ripening. SlPP2C3 selectively interacted with monomeric ABA receptors and SlSnRK2.8 kinase in both yeast and tobacco epidermal cells. Expressions of <i>SlPP2C3 </i>were observed in all tissues, and it negatively correlated with the fruit ripening which was induced by exogenous ABA. Tomato plants with suppressed <i>SlPP2C3</i> expression exhibited enhanced sensitivity to ABA, while <i>SlPP2C3</i> over-expressed plants were less sensitive to ABA. Meaningfully, lack of <i>SlPP2C3</i> expression causes the acceleration of fruit ripening onset via the alternation of ABA signaling activity, and the fruit gloss is affected by the changes of outer epidermis structure. RNA-seq analysis found significant different expression of cuticle-related genes in pericarp between wild-type and <i>SlPP2C3</i> suppressed lines. Taken together, our finding demonstrate that SlPP2C3 plays an important role in the regulation of fruit ripening and fruit appearance quality in tomato. </span></p>
Population studies of the wild tomato species Solanum chilense reveal geographically structured major gene-mediated pathogen resistance
<p>Natural plant populations encounter strong pathogen pressure and defense-associated genes are known to be under selection dependent on the pressure by the pathogens. Here we use populations of the wild tomato Solanum chilense to investigate natural resistance against Cladosporium fulvum, a well-known ascomycete pathogen of domesticated tomatoes. Host populations used are from distinct geographical origins and share a defined evolutionary history. We show that distinct populations of S. chilense differ in resistance against the pathogen. Screening for major resistance gene mediated pathogen recognition throughout the whole species showed clear geographical differences between populations and complete loss of pathogen recognition in the south of the species range. In addition, we observed high complexity in a homologues of Cladosporium resistance (Hcr) locus, underlying the recognition of C. fulvum, in central and northern populations. Our findings show that major gene mediated recognition specificity is diverse in a natural plant-pathosystem. We place major gene resistance in a geographical context that also defined the evolutionary history of that species. Data suggest that the underlying loci are more complex than previously anticipated, with small-scale gene recombination being possibly responsible for maintaining balanced polymorphisms in the populations that experience pathogen pressure.</p>
