“…As an economically important vegetable, tomato plays an important role in balancing people's diets. Tomato fruits are rich in sugars, dietary fiber, minerals, essential amino acids, and vitamins (Olaiya, 2011). Tomato also contributes to the experimental sciences such as in studies on defense regulation against stresses, breeding, fruit development, and ripening (Klee and Giovannoni, 2011; Schauer et al, 2008).…”

Tomato yellow leaf curly virus (TYLCV), transmitted by the whitefly (Bemisia tabaci), causes leaf curling and yellowing, plant dwarfism, and growth inhibition in tomato (Solanum lycopersicum L.). The APETALA2 (AP2) and ethylene response factor (ERF) transcription factor (TF) family, the largest plant-specific TF family, was identified to function in plant development and pathogen defense. Our study aimed to analyze the mechanism underlying the function of S. lycopersicum ERF (SlERF) TFs in response to TYLCV infection and improve useful information to increase the resistance to TYLCV in tomato. A total of 22 tomato AP2/ERF TFs in response to TYLCV were identified according to transcriptome database. Five ERF-B3 TFs were identified in cultivars Hongbeibei (highly resistant), Zheza-301, Zhefen-702 (both resistant), Jinpeng-1, and Xianke-6 (both susceptible). Interaction network indicated that SlERF TFs could interact with mitogen-activated protein kinase (MAPK). Expression profiles of five ERF-B3 genes (Soly19, Soly36, Soly66, Soly67, and Soly106) were detected by quantitative real-time-polymerase chain reaction (qRT-PCR) after TYLCV infection in five tomato cultivars. Soly106 expression was upregulated in five tomato cultivars. The expressions of three genes (Soly19, Soly67, and Soly36) were upregulated in Zheza-301 and Zhefen-702. Soly66 and Soly36 expressions were downregulated in Hongbeibei and Xianke-6, respectively. Yeast one-hybrid showed that the GCC-box binding ability of ERF-B3 TFs differed in resistant and susceptible tomato cultivars. Expression profiles were related to the GCC-box binding ability of SlERF TFs in resistant and susceptible tomato cultivars. The defense mechanism underlying the tomato's response to TYLCV involved a complicated network, which provided important information for us in breeding and genetic analysis.

“…Due to the large variation in yield of openfield tomatoes, it is necessary to seek for genotypes more resistant to climatic conditions. A well chosen cultivar and application of modern cultivation technologies are helpful in obtaining high-quality yield and favourably affect the profitability of production (Legańska & Balcerzak 2000, Elkner et al 2004, Jędrszczyk 2010, Olaiya 2011. Cultivar is a genetic factor that determines the characteristics of morphological, physical, chemical, uniform ripening, suitability for mechanical harvesting, fertility and susceptibility to diseases and pests (Bąkowski 1999).…”

SummaryExperiment took place in the open field in the Vegetable Experimental Station of Agricultural University near Cracow in the years 2008-2010. In the experiment twelve, polish-bred determinate tomato cultivars: Sokal F 1 , Batory F 1 , Rejtan F 1 , Hetman F 1 , Babinicz, Luban, Mieszko F 1 , III A F 1 , Awizo F 1 , Ondraszek, Talon and Hubal were used. In the end of growing season, morphological features of plant were measured, concerning: height of plant, number of lateral shoots, length and thickness of the internode and the number of inflorescences per plant. Harvesting was performed once, at the stage of maturity of individual cultivars. The yield and its structure was calculated. The results were statistically analyzed using NIR Fisher's test, with p=0.05. The dependences of the marketable yield and total yield of tomato plants from morphological characteristics that may affect the yield were analyzed, using multiple regression. The amount of total and marketable yield was negatively correlated with an extensive vegetative growth of tomato plants. Among all the tested cultivars Ondraszek was characterized by the most preferred morphological features and creates one of the highest yields. Cultivars Ondraszek, Sokal F 1 and Batory F 1 were characterized higher marketable yield, than 'Hetman F 1 '. Total and marketable yield depended about 40% on tomato plant morphological features.
