    Opis:
    Inheritance of tomato resistance to P. infestans was studied in progenies of crosses of resistant accessions: West Virginia 700, Ottawa 30, PI224675 and the variety New Yorker and also of the variety West Virginia’63 and resistant breeding lines crossed with susceptible forms. Populations of F1, F2, parents and resistant standards were evaluated for resistance to late blight using the test on seedlings grown in liquid medium. Resistance of the accessions West Virginia 700, Ottawa 30 and PI224675 was found to be identical and determined by the same genes: Ph-1 and Ph-2. It has not been recognized if these accessions carry other genes, neither if the variety West Virginia’63 and lines of equal resistance possess other genes beside Ph-2.

    Opis:
    Mycorrhizal fungi influence the development and activity of communities of soil microorganisms. The purpose of this study was to estimate the effect of arbuscular mycorrhizal fungus Claroideoglomus etunicatum (W. N. Becker & Gerd.) C. Walker & Schüβler on the population structure of fungal colonies in the rhizosphere of tomatoes grown in a plastic tunnel. The field experiment was conducted from 2015 to 2017 at an ecological farm in Grądy, central eastern Poland. The object of study were the three tomato cultivars: ‘Antalya F 1 ’, ‘Esmira F 1 ’, and ‘Pelikan F 1 ’. Tomato seedlings were inoculated with C. etunicatum; spores were introduced about 5 cm deep in the rhizosphere of the studied plants (25–30 spores of C. etunicatum for each plant). Each year, mycological analysis of the tomato rhizosphere was conducted using Warcup’s method; structure of fungal communities of the tomato rhizosphere varied depending on the AMF applied. Saprotrophic fungi such as Trichoderma ssp., Mucor spp., and Penicillium spp. were often more isolated from the rhizosphere of plants inoculated with C. etunicatum than that of the control samples. It can be concluded that AMF directly impacted the development of fungal biodiversity in the tomato rhizosphere, particularly regarding the number of saprotrophs in the soil.

    Opis:
    A laboratory test for evaluating the tomato leaf resistance to Phytophthora infestans in the seedling stage has been developed. The test is suitable for evaluation of breeding lines and selection within large populations. The following standard varieties and accessions representing a whole range of variability of known resistance were used: Moneymaker, New Yorker, West Virginia`63, West Virginia 700 and Ottawa 30. Various P. infestans isolates were used in the tests. Tomato seedlings grown in a liquid medium were cultured and tested in a growth chamber. The infection of individual seedlings was evaluated using 9-degree logistic key and data were statistically estimated. The results were reproducible in the same growth   conditions. Ranking of infection degree was as follow: Moneymaker ≥ New Yorker > West Virginia`63 > West Virginia 700 = Ottawa 30 irrespectively of test conditions or the isolates applied. The laboratory ranking was consistent with field observations. The results of tests depended on concentration of liquid medium (lower infection at lower concentration), on the isolate used and its spore concentration. The method proposed meets all requirements necessary for breeding and research as a routine method for evaluation of the tomato leaf resistance to P. infestans.

    Opis:
    In August 2016, tomato plants grown during a hot, wet summer with heavy soil flooding, displaying symptoms of wilting, dead plant, root rot with crown and stem rot, at Beni Suef and Fayoum governorates were examined. A number of 16 fungal isolates were isolated from tomato plants displaying the above symptoms. These isolates were classified as belonging to six species, namely: Alternaria solani, Chaetomium globosum, Fusarium solani, Fusarium oxysporum, Pythium spp. and Rhizoctonia solani. Isolates of Pythium spp. were prevalent and were found to be more pathogenic than the other fungal isolates. This species causes damping-off, root rot, sudden death, stem rot and fruit rot. The pathogen was identified as Pythium aphanidermatum based on morphological, cultural, and molecular characteristics. Biogenic silver nanoparticles (AgNPs) were produced using the F. oxysporum strain and characterized by transmission electron microscopy (TEM). The size of these spherical particles ranged from 10 to 30 nm. In vitro, biogenic AgNPs showed antifungal activity against P. aphanidermatum. In greenhouse and field experiments, AgNPs treatment significantly reduced the incidence of dead tomato plants due to root rot caused by P. aphanidermatum compared to the control. All of the investigated treatments were effective and the treatment of root dipping plus soil drenching was the most effective. To the best of our knowledge, this study describes P. aphanidermatum on tomato in Egypt for the first time. Also, biogenic AgNPs could be used for controlling root rot disease caused by this pathogen.

    Opis:
    We examined the response of maturing tomato fruit exposed for 7 days to fluridone (1-methyl-3-phenyl-5-[3-trifluoromethyl(phenyl)]-4(1H)-pyridinone). Fluridone was applied in lanolin paste in the form of a 2–3 mm wide strip from the top to the base of the fruit. As a control, a similar stripe of lanolin was applied in the same way on the opposite side of the same fruit. The content of major carotenoids, as well as flavonoids, and free and bound phenolic acids were determined using a HPLC and HPLC-MS-MS methods. Fluridone almost completely blocked the biosynthesis of lycopene and substantial declined content of ß-carotene and lutein in the tomato fruit. The fluridone caused a decreased content of quercetin, rutin and naringenin, and increased level of epicatechin. The herbicide did not affect the content of p-coumaric acid, but reduced the level of caffeic acid, both free and ester form, and declined the content of free ferulic and chlorogenic acids. Changes in phenolics composition observed for the first time indicate that fluridone interferes with the biosynthesis of further products of the metabolism of p-coumaric acid, both flavonoids and phenolic acids.

    Opis:
    Processing tomato production represents an important part of the total production of processed vegetables in the world. The quality characteristics of processing tomato, important for the food industry, are soluble solids content and antioxidant content (such as lycopene and polyphenols) of the fruit. Analytical quantification of these components is destructive, time and labour consuming. That is why researchers try to develop a non-destructive and rapid method to assess those quality parameters. The present study reports the suitability of a portable handheld visible near infrared spectrometer to predict soluble solids, lycopene and polyphenol content of tomato fruit puree. Spectral ranges of 500-1000 nm were directly acquired on fruit puree of five different tomato varieties using a FieldSpec HandHeld 2™ Portable Spectroradiometer. Immediately after spectral measurement, each fruit sample was analysed to determine soluble solids, lycopene and polyphenol content. Partial least square regressions were carried out to create models of prediction between spectral data and the values obtained from the analytical results. The accuracy of the predictions was analysed according to the coefficient of determination value (R2), the root mean square error of calibration/cross-validation.

    Opis:
    Fusarium species are causal agents of fungal diseases occurring frequently in numerous agriculturally important plants, including potato, garlic and are one of the common pathogens of tomato, causing root rot in the west part of Iran. Therefore, the objectives of this study were to isolate and identify disease-causing Fusarium species from infected tomatoes based on the morphological and molecular characteristics. Twenty-five isolates of Fusarium were obtained from infected root of tomato plants collected from the fields in different regions of western Iran. Based on morphological features, the strains were classified into four following Fusarium species: F. oxysporum, F. redolens, F. proliferatum and F. verticillioides. The phylogenetic trees based on tef1 and tub2 dataset clearly distinguished closely related species. All of the isolates were evaluated for their pathogenicity on healthy tomato seedlings in the greenhouse. This is the first report on molecular identification of Fusarium species isolated from tomato plants cultivated in Iran.

    Opis:
    To compare the effect of NaCl, CaCl2 and their combinations on germination and early seedling growth stages of Lycopersicum esculentum L., were studied under pot experiments 2008. Results indicated that significant increases were recorded in percentage of germination, seedling fresh and dry weights, seedling length, water content, catalase activity and photosynthetic pigments (chlorophyll a, b and total chlorophylls as well as carotenoids) under the low level concentration (20 mM) of NaCl or CaCl and their combination (1:1). On other hand increasing salt concentration in nutrient solution caused significant decrease in all of these parameters. The great reduction occurred under high salinity level of NaCl (50 mM). Meanwhile, peroxidase activity increased significantly with increasing salinity levels from 20 mM to 50 mM of both applied salinity types. Besides, peroxidase activity under NaCl salinity showed a marked increase followed by NaCl + CaCl2 (1:1) and CaCl2 at 50 mM.

    Opis:
    The sequence of anatomical and ultrastructural events leading to the syncytium development in tomato roots infected with Globodera rostochiensis was examined. The syncytia were preferentially induced in cortical or pericyclic cells in the elongation zone of root. They developed towards the vascular cylinder by incorporation of new cells via local cell wall breakdown. After surrounding primary phloem bundle and reaching xylem tracheary elements syncytia spread along vascular cylinder. Roots in primary state of growth seemed to be the best place for syncytium induction as syncytia formed in the zone of secondary growth were less hypertrophied. At the ultrastructural level syncytial elements were characterized by strong hypertrophy, breakdown of central vacuole, increased volume of cytoplasm, proliferation of organelles, and enlargement of nuclei. On the syncytial wall adjoining vessels the cell wall ingrowths were formed, while the syncytial walls at interface of phloem were considerably thickened. They lacked of functional plasmodesmata and did not form any ingrowths. Using immunofluorescent-labelling and immunogold-labelling methods tomato expansin 5 protein was localized in nematode infected roots. The distribution of LeEXP A5 was restricted only to the walls of syncytia. The protein distribution pattern indicated that LeEXP A5 could mediates cell wall expansion during hypertrophy of syncytial elements.
