Abstract:
... Fruit ripening of tomato is regulated by NAC (NAM, ATAF1/2, and CUC2) domain proteins such as NOR-like1, SlNAC1, and SlNAC4. Acts as an up-stream regulator of NAC genes, the high abundance of miR164 might eliminate the impact of NAC on the ripening of fleshy fruit. In the present study, the STTM-miR164a (silencing miR164a by short tandem target mimic) and OE-miR164a (overexpression of miR164a) tom ...

Abstract:
... Thermal stabilities of lycopene and β-carotene in tomato pulp and pink grapefruit juice were studied at 80, 95 and 110 °C. Lycopene and β-carotene degradations in both products followed to first-order reaction kinetics, but biphasic curves were obtained for β-carotene degradation. Stabilities of both pigments are highly affected by processing temperatures. For example, t₁/₂ values for lycopene deg ...

Abstract:
... Our food system is very resource and emissions intensive and contributes to a broad range of environmental impacts. We have developed cradle-to-market greenhouse gas emissions estimates of supplying fresh tomatoes to 10 of the largest metropolitan areas in the United States and applied a linear optimization algorithm to determine the optimal tomato distribution scheme that will minimize tomato-rel ...

Abstract:
... Drought management largely depends on the availability of timely, accurate and integrated information about its characteristics. Concurrently, biostimulants could represent a sustainable measure to foster the resilience of cropping systems under water-limited conditions. Nevertheless, scientific recognition of the potential of biostimulants has not grown as fast as the interest from industry: ther ...

Abstract:
... Growing conditions and agronomical inputs play a key role in determining fruit qualitative and nutraceutical traits at harvest and post-harvest. The hereby presented research investigated the effects of pre-harvest supplemental LED interlighting on post-harvest quality of hydroponically grown tomatoes (Solanum lycopersicum “Siranzo”). Three LED treatments, applied for 16 h d⁻¹ (h 8.00–00.00), were ...
... In this study, tomato seed oil conventional emulsion (7 μm) and nanoemulsion (0.146 µm) with desirable stability were prepared, then the effect of tomato seed oil addition (bulk and emulsified forms) and thermal treatment on properties of tomato juice was evaluated. Tomato juice without oil and heat treatment exhibited the lowest bioaccessibility of lycopene (17.8 %). Incorporation of oil and appl ...

Abstract:
... Aldehyde and ketone compounds are ubiquitous in the air and prone to adverse effects on human health. Cooking emission is one of the major indoor sources. Aiming to evaluate health risks associated with inhalation exposure to aldehyde and ketone compounds, 13 carbonyl compounds (CCs) released from heating 5 edible oils, 3 seasonings, and 2 dishes were investigated in a kitchen laboratory. For the ...

Abstract:
... Food safety and quality assessment mechanisms are unmet needs that industries and countries have been continuously facing in recent years. Our study aimed at developing a platform using Machine Learning algorithms to analyze Mass Spectrometry data for classification of tomatoes on organic and non-organic. Tomato samples were analyzed using silica gel plates and direct-infusion electrospray-ionizat ...

Abstract:
... NAC transcription factors (TFs) play an important role in the plant resistant response to biotic and abiotic stresses. However, the functions of the most NAC TFs are still unknown, especially in tomato. Here, we identified and functionally characterized an NAC TFs, SlNAP1, in tomato, and found that SlNAP1 was significantly induced by salt stress. Under 150 mM NaCl treatments, morphological indexes ...

Abstract:
... Agricultural production has improved with the development of water deficit (WD) irrigation technology, but the impact of the application of WD irrigation on product quality is still understudied. The effects of WD irrigation on the transcriptome and metabolome of fruit have been investigated by treating tomato plants with control or WD irrigation during the growing period. WD irrigation promoted t ...
... Iron (Fe) is a micronutrient for plant development, as constituent of several photosynthesis- and respiration-related proteins and enzymes. Consequently, Fe deficiency leads to chlorosis in leaves and plant growth impairment. It has become increasingly evident that light signals coordinate iron homeostasis in plants. To further address new insights into how light is a fundamental part of Fe defici ...

Abstract:
... Non-expresser of pathogenesis-related genes 1 (NPR1) has been demonstrated to be a master transcription factor during resistance against pathogens, the mechanisms by which regulates chilling stress, however, remain unclear. Our results revealed that the expression and protein content of SlNPR1 were dramatically induced by low temperature (4 °C). CRISPR/Cas9-mediated SlNPR1 mutagenesis aggravated t ...

Abstract:
... Pasteurization of crushed tomato in glass bottles was evaluated using a multiphysics model, aiming to understand the temperature profiles and quality losses during the heating and cooling stages of the process. In order to rigorously simulate the pasteurization process, a finite element model was built using experimentally measured product and heat transfer parameters (thermal conductivity, densit ...
... The cherry tomato (Solanum lycopersicum L.) seedling stage frequently experiences waterlogging due to heavy autumn rainfall in tropical areas, which impairs cherry tomato growth and development. In this study, we investigated the effects of exogenous spermidine and calcium on the morphological, physiological and biochemical traits of two popular cherry tomato cultivars (Hongfei6: flooding-insensit ...
... This research evaluated the inactivation of Salmonella spp. and Listeria monocytogenes inoculated onto the calyces of blueberries, stem scars of cherry tomatoes, and surfaces of grapes using gaseous chlorine dioxide (ClO₂) produced by the reaction between sodium chlorite (NaClO₂) and carbon dioxide (CO₂). The inoculated samples were treated with ClO₂ gas in a treatment chamber for 3 h. The results ...
... Recent increases in soil-borne plant disease have limited further expansion of some crops produced in protected agriculture. Soil fumigation effectively minimizes the impact of soil pathogens causing many diseases. We provide the first report of the efficacy of the Chinese fungicide ethylicin as a soil fumigant against the plant pathogens such as Fusarium spp. and Phytophthora spp., and against th ...

Abstract:
... Plants developed a series of defence mechanisms to counteract the attack of herbivores. These can impact on food‐webs at various trophic levels, in both natural and managed ecosystems, such as crops. The biochemical and ecological bases behind these processes are reviewed here by highlighting the differences in direct and indirect, constitutive and induced defences. In integrated pest management ( ...
