Tomatine (sometimes called tomatin or lycopersicin) is a glycoalkaloid, found in the stems and leaves of tomato plants, and in the fruits at much lower concentrations. It has fungicidal, antimicrobial, and insecticidal properties. Chemically pure tomatine is a white crystalline solid at standard temperature and pressure. Tomatine, as well as the closely related aglycon (or aglycone) derivative tomatidine have been shown to have multiple health benefits. Tomatine is sometimes confused with the glycoalkaloid solanine, which is found in potatoes. Tomatoes were brought to Europe in the 1590s. The English botanist John Gerard was one of the first cultivators of the tomato plant. In his publication Grete Herball, he considered tomatoes as poisonous due to their levels of what would later be called tomatine, plus high acid content. Consequently, tomatoes were generally not eaten in Britain until the mid-18th century. In 1837, the first medicinal tomato pills were advertised in the United States because ...
In the present study, the molecular mechanisms involved in the α‑tomatine‑induced apoptosis in human glioblastoma cell lines A172 and U‑118 MG were investigated. Wright staining and ApopTag assays were conducted to confirm the apoptosis induced by α‑tomatine treatment. Fura‑2 assay determined an enhancement in free Ca2+ intracellularly, indicating the occurrence of Ca2+‑dependent apoptosis induction. Western blot experiments were also performed to predict the apoptosis by measuring the changes in the Bax:Bcl‑2 ratio. Increase of calpain activity triggered caspase‑12 expression, which in turn further activated caspase‑9. In addition, an increase in the ratio of Bax:Bcl‑2 accounted for the mitochondrial release of cytochrome c into the cytosol for caspase‑3 and caspase‑9 activation. Elevated activity of calpain and caspase‑3 yielded spectrin breakdown products with 145 and 120 kDa, respectively. Caspase‑3 activation further cleaved the inhibitor of caspase activated ...
Abstract High temperatures affect potato production in the tropics, putting tuber yield and quality at risk and leading to increased glycoalkaloid concentration the cause of the bitter taste in potatoes and a cause for concern for human health. The International Potato Center (CIP), has developed new heat tolerant clones which are heat tolerant and also resistant to late blight. These clones offer an opportunity to evaluate yield and glycoalkaloid levels after growth under high temperature environments. We evaluated four sets of 16 full-sib families and 20 clones for tuber yield and glycoalkaloid content in order to estimate narrow-sense and broad-sense heritability respectively. We used a randomized complete block design replicated in three locations in Peru; San Ramon, La Molina and Majes At harvest, the number and weight of marketable and nonmarketable tubers were recorded. We analyzed samples of tubers from each clone for glycoalkaloid content using spectrophotometry. Narrow-sense heritability for

Steroidal glycoalkaloids (SGAs) are toxic specialized metabolites that are found in the Solanaceae. Potato (Solanum tuberosum) contains the SGAs α-solanine and α-chaconine, while tomato (Solanum lycopersicum) contains α-tomatine, all of which are biosynthesized from cholesterol. However, although two cytochrome P450 monooxygenases that catalyze the 22- and 26-hydroxylation of cholesterol have been identified, the 16-hydroxylase remains unknown. Feeding with deuterium-labeled cholesterol indicated that the 16α- and 16β-hydrogen atoms of cholesterol were eliminated to form α-solanine and α-chaconine in potato, while only the 16α-hydrogen atom was eliminated in α-tomatine biosynthesis, suggesting that a single oxidation at C-16 takes place during tomato SGA biosynthesis while a two-step oxidation occurs in potato ...

We sequenced and compared the genomes of the Dothideomycete fungal plant pathogens Cladosporium fulvum (Cfu) (syn. Passalora fulva) and Dothistroma septosporum (Dse) that are closely related phylogenetically, but have different lifestyles and hosts. Although both fungi grow extracellularly in close contact with host mesophyll cells, Cfu is a biotroph infecting tomato, while Dse is a hemibiotroph infecting pine. The genomes of these fungi have a similar set of genes (70% of gene content in both genomes are homologs), but differ significantly in size (Cfu ,61.1-Mb; Dse 31.2-Mb), which is mainly due to the difference in repeat content (47.2% in Cfu versus 3.2% in Dse). Recent adaptation to different lifestyles and hosts is suggested by diverged sets of genes. Cfu contains an alpha-tomatinase gene that we predict might be required for detoxification of tomatine, while this gene is absent in Dse. Many genes encoding secreted proteins are unique to each species and the repeat-rich areas in Cfu are ...

Aims: To isolate Fusarium oxysporum f.sp. lycopersici from infected tomato plants in selected tomato producing agroecological areas in Southwestern Nigeria and evaluate susceptibility of F1-resistant tomato hybrid (F1-Lindo) to infection, to understand the propensity of adopting the hybrid.. Methodology: Seven F. oxysporum f.sp. lycopersici were isolated from infected tomato plants collected from some tomato producing agroecological areas in the Southwestern Nigeria. The isolates were identified using their morphological features and characterized based on growth, sporulation rates, lag-time and virulence. Growth rate was estimated using a linear model for estimation of fungal growth. Conidia of five of the isolates were standardized to 1.0 x 106 conidia/mland tested for virulence against Race-1-resistant tomato hybrid, F1-Lindo. Pathogenicity of the fungal isolates were ranked according to severity of damage to the tomato hybrid.. Results: The growth, sporulation rates and the lag time of the ...
A Brazilian isolate of Fusarium oxysporum f. sp. phaseoli (F. o. f. sp. phaseoli) was used to determine the reactions of 66 lines of beans to the Fusarium yellows pathogen in greenhouse tests. The distal 1 cm of root tips of 1-wk-old seedlings grown in sterilized sand were removed, roots were dipped in a spore suspension of F. o. f. sp. phaseoli for 5 min, and the seedlings were then transplanted into pots filled with pasturized soil. As the concentration of F. o. f. sp. phaseoli spores was increased from 0 to 1 × 107 / ml, incubation time to the first disease symptom was decreased and disease severity ratings (DSR) increased on the field-susceptible cultivar IPA 1. However, only slight disease symptoms occurred at a spore concentration of 1 × 107 on the line HF 465-63-1, known to show resistance under field conditions in Brazil. Severely infected plants became defoliated and often died within 2 3 wk. The dead stem and petiole tissues were covered with pink to orange spore masses. The extent ...

The fungitoxicity of acetone extracts from the xylem of Fusarium wilt disease resistant tomato plants (cv. Jefferson) inoculated with Fusarium oxysporum f. sp. lycopersici was greatly influenced by environmental factors. Extracts obtained from plants 1 h after watering were 4-times more toxic than extracts from plants subjected to water stress for 5 h before extraction, and 10-times more toxic than those from plants after 23.5 h of water stress. Materials from plants extracted at various times during the day exhibited a striking diurnal pattern of antifungal activity. Material from plants extracted at the end of the dark period were the most toxic, and extracts obtained at the end of the light period were the least toxic. The extracts were most toxic to the pathogen in vitro at pH 4.5 and were completely ineffective at pH 6.0 and above. Monogenic resistance of tomato to race 1 of the wilt pathogen was negated by the application of 1% ethanol through the roots. Vascular and foliar disease ...

Previous reports showed that the Steroidal Glycoalkaloid Solamargine inhibited proliferation of non-melanoma skin cancer cells. However, Solamargine was not tested systematically on different types of melanoma cells and was not simultaneously tested on normal cells either. In this study we aimed to investigate the effect of Solamargine and the mechanism involved in inhibiting the growth of different types of melanoma cells. Solamargine effect was tested on normal cells and on another three melanoma cell lines. Vertical growth phase metastatic and primary melanoma cell lines WM239 and WM115, respectively and the radial growth phase benign melanoma cells WM35 were used. The half inhibitory concentration IC50 of Solamargine was determined using Alamarblue assay. The cellular and subcellular changes were assessed using light and Transmission Electron Microscope, respectively. The percentage of cells undergoing apoptosis and necrosis were measured using Flow cytometry. The different protein expression was

The compounds, sarcovagine-D, alkaloid-C and holaphylline isolated from Sarcococca saligna were found to possess immunosuppressive activities. These compounds were characterized for in-vitro inhibition on human T-cells proliferation and IL-2 production. The compounds showed significant immunosuppressive effect on IL-2 production as well as on phytohemagglutinin stimulated T-cell proliferation in a dose dependent manner. Of all the tested compounds holaphylline was found to be less toxic and safe. These compounds were then evaluated for their in-vivo hepatoprotective potential against CCl4, in which alkaloid-C and holaphylline showed markedly reduced liver inflammation and biochemical parameter (ALT, AST, and ALP) of liver injury. The decrease in the activity of hepatic antioxidant enzyme (SOD) was significantly prevented by holaphylline, likewise gradually the levels of MDA and GSH were also normalized compared to silymarin.

Biostimulants inducing plant defences is among the promising approaches to reduce the chemical pesticides use in wheat protection against Septoria leaf blotch caused by the hemibiotrophic Zymoseptori tritici. Within this scope, the effect of seed coating with the bacterium Paraburkholderia phytofirmans (PsJN strain) or thyme oil on triggering wheat systemic resistance to Septoria leaf blotch under controlled conditions was investigated using histopathological, physiological and biochemical approaches. Both products reducednecrosis, pycnidial density,associated with induction of programmed cell death, papillae accumulation in the biotrophic stage, and lowerperoxidase activity, H2O2, catalase and phenolic content in the necrotophic stage. Thyme oilinduced systemic acquired resistancewhile PsJN strain triggered induced systemic resistance to Septoria leaf blotch.
There are several potential ways in which jasmonates could mediate the early response to Xcv. First, JA may not be the active jasmonate mediating the response. We observed increased OPDA accumulation following infection, but the increase was inconsistent. It is possible that another unmeasured oxylipin may be mediating this pathogen response. Recent findings of other groups indicate that OPDA is biologically active (for review, see Blee, 2002). For example, Stintzi et al. (2001) showed that OPDA is sufficient to mount defense responses. Rather than JA alone, it has been proposed that the "oxylipin signature" is the overall determinant of a stress response (Kramell et al., 2000; Göbel et al., 2002; Howe and Schilmiller, 2002). Alternatively, sensitivity to jasmonates may be heightened following Xcv infection. Alterations in hormone sensitivity following pathogen infection are not unprecedented (Ciardi et al., 2001). In Arabidopsis, the jasmonate-signaling mutant, coi1, exhibits hyperactivation ...

We found it a very good producer, and although it came to a premature end (like every single other non-cherry tomato in the garden this year) due to septoria spot, it produced very generously compared to many of the others. The tomatoes are a very large, quite dense beefsteak type tomato - ideal for sandwiches, pizza and the like. Some of them blushed pink on the bottom as they ripened. These are a large, rangy, indeterminate plant (which is why it survived the septoria spot fairly well - all those that survived did so by out-growing it) and it will need lots of room and staking. Its a bit of a late starter, at 85 days. It is said to be crack and drought resistant, and indeed I would say so. We had a very trying year for tomatoes, with a wet, cold June followed by a hot, dry July and and hot-mostly-dry-but-intermittently-quite-wet August. In other words, the exact weather to make tomatoes crack and many of them did. Not Great White. It may have some tendency to Blossom End Rot, but we had no ...

The I-2 locus in tomato confers resistance to race 2 of the soil-borne fungus Fusarium oxysporum f sp lycopersici. The selective restriction fragment amplification (AFLP) positional cloning strategy was used to identify I-2 in the tomato genome. A yeast artificial chromosome (YAC) clone covering ~750 kb encompassing the I-2 locus was isolated, and the AFLP technique was used to derive tightly linked AFLP markers from this YAC clone. Genetic complementation analysis in transgenic R1 plants using a set of overlapping cosmids covering the I-2 locus revealed three cosmids giving full resistance to F. o. lycopersici race 2. These cosmids shared a 7-kb DNA fragment containing an open reading frame encoding a protein with similarity to the nucleotide binding site leucine-rich repeat family of resistance genes. At the I-2 locus, we identified six additional homologs that included the recently identified I-2C-1 and I-2C-2 genes. However, cosmids containing the I-2C-1 or I-2C-2 gene could not confer ...
Background: Soil-borne fungi of the Fusarium oxysporum species complex cause devastating wilt disease on many crops including legumes that supply human dietary protein needs across many parts of the globe. We present and compare draft genome assemblies for three legume-infecting formae speciales (ff. spp.): F. oxysporum f. sp. ciceris (Foc-38-1) and f. sp. pisi (Fop-37622), significant pathogens of chickpea and pea respectively, the worlds second and third most important grain legumes, and lastly f. sp. medicaginis (Fom-5190a) for which we developed a model legume pathosystem utilising Medicago truncatula. Results: Focusing on the identification of pathogenicity gene content, we leveraged the reference genomes of Fusarium pathogens F. oxysporum f. sp. lycopersici (tomato-infecting) and F. solani (pea-infecting) and their well-characterised core and dispensable chromosomes to predict genomic organisation in the newly sequenced legume-infecting isolates. Dispensable chromosomes are not essential ...

Inoculation of wheat seedlings with certain combinations of isolates of Septoria tritici resulted in marked reductions in pycnidial coverage of leaves compared with plants inoculated separately with individual components of the mixture. The effect was greater when the isolates were grown together than when grown separately and mixed before inoculation. The suppression of pycnidial formation did not depend on the ratio of the isolates in the mixtures. The addition of a culture filtrate from one isolate to the conidial preparation of another isolate resulted in marked symptom suppression. In conidial preparations where the growth medium was decanted and the spores were resuspended in fresh medium, marked reductions in pycnidial coverages were observed on all cultivars. These results suggest that S. tritici may produce substances that regulate the expression of symptoms on wheat leaves inoculated with isolate mixtures. Challenge inoculations of Kavkaz winter wheat with an isolate several days after ...

Tomato crops can be affected by several infectious diseases produced by bacteria, fungi, and oomycetes. Four phytopathogens are of special concern because of the major economic losses they generate worldwide in tomato production; Clavibacter michiganensis subsp. michiganensis and Pseudomonas syringae pv. tomato, causative agents behind two highly destructive diseases, bacterial canker and bacterial speck, respectively; fungus Fusarium oxysporum f. sp. lycopersici that causes Fusarium Wilt, which strongly affects tomato crops; and finally, Phytophthora spp., which affect both potato and tomato crops. Polygodial (1), drimenol (2), isonordrimenone (3), and nordrimenone (4) were studied against these four phytopathogenic microorganisms. Among them, compound 1, obtained from Drimys winteri Forst, and synthetic compound 4 are shown here to have potent activity. Most promisingly, the results showed that compounds 1 and 4 affect Clavibacter michiganensis growth at minimal inhibitory concentrations (MIC) values
Fusarium wilt of strawberry, incited by Fusarium oxysporum f. sp. fragariae (Fof), is a major disease of the cultivated strawberry (Fragaria xananassa) worldwide. An increase in disease outbreaks of the pathogen in Western Australia and Queensland plus the search for alternative disease management strategies place emphasis on the development of resistant cultivars. In response, a partial incomplete diallel cross involving four parents was performed for use in glasshouse resistance screenings. The resulting progeny were evaluated for their susceptibility to Fof. Best-performing progeny and suitability of progenies as parents were determined using data from disease severity ratings and analyzed using a linear mixed model incorporating a pedigree to produce best linear unbiased predictions of breeding values. Variation in disease response, ranging from highly susceptible to resistant, indicates a quantitative effect. The estimate of the narrow-sense heritability was 0.49 +/- 0.04 (SE), suggesting ...
Corky root rot (CRR) is an escalating plant disease of tomato (Solanum esculentum), caused by a soil-borne fungus, Pyrenochaeta lycopersici. During the last two decades there have almost been no progress in the understanding of the molecular mechanisms promoting infection and plant susceptibility. As there are no CRR-resistant lines of cultivated tomato on the market and no other known means for plant protection, a deeper molecular knowledge about the infection process is urgently needed. We have therefore outlined an efficient strategy to search for corky root rot-resistance genes in wild tomato. In addition, we are investigating the genetic determinants for infection and virulence of the fungal pathogen, P. lycopersici. In this review we summarize the quite limited molecular knowledge about the pathogen and the disease, and discuss the possibilities to overcome previous technical obstacles in this new era of molecular biology.. ...

W somnifera (ashwagandha), also referred to as winter cherry (family Solanaceae), grows in Africa, the Mediterranean, India, Pakistan, Bangladesh, Afghanistan, South Africa, Egypt, Morocco, Congo and Jordan [36]. The roots of the plant contain steroid alkaloids and steroidal lactone, which are the main constituents of ashwagandha; these compounds are referred to as withanolides. Among the various alkaloids, withnine is the main constituent. The other alkaloids are somniferin, somnine, somniferine, withananine, pseudowithanine, tropine, pseudotropine, cuscohygrine, anferine and anhydrine. Two acyl steryl glucosides (sitoindoside VII and sitoindoside VIII) have been isolated from the root. The withanolides contain a C28 steroidal nucleus with a C9 side chain and six-membered lactone rings. Ashwagandha root also contains flavonoids and many ingredients of the withanolide class. It has several medicinal applications (aphrodisiac, liver tonic, anti-inflammatory agent, astringent), and is used to ...
