Color defines one aspect of quality for tomato and tomato products. Carotenoid pigments are responsible for the red and orange colors of tomato fruit, and thus color is also of dietary interest. The aims of this study were (1) to determine the relative importance of field sampling and analytical replication when measuring lycopene and beta-carotene in tomato fruit and (2) to determine the effec...

Turhan A., Ozmen N., Serbeci M.S., Seniz V., 2011. Effects of grafting on different rootstocks on tomato fruit yield and quality. Hort. Sci. (Prague), 38: 142–149. The aim of the study was to find effects of tomato grafting on another cultivar. The tomato cultivars used as scions were Yeni Talya, Swanson and Beril. Cultivars used as rootstocks were Beaufort and Arnold. Cleft grafting methods we...

Gene-to-gene coexpression analysis provides fundamental information and is a promising approach for predicting unknown gene functions in plants. We investigated various associations in the gene expression of tomato (Solanum lycopersicum) to predict unknown gene functions in an unbiased manner. We obtained more than 300 microarrays from publicly available databases and our own hybridizations, an...

to evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. in this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

The most distinctive morphogenetic feature of leaves is their being either simple or compound. To study the basis for this dichotomy, we have exploited the maize homeobox-containing Knotted-1 (Kn1) gene in conjunction with mutations that alter the tomato compound leaf. We show that misexpression of Kn1 confers different phenotypes on simple and compound leaves. Up to 2000 leaflets, organized in...

The availability of an entire plant genome allows for many new insights into areas such as chromosome architecture, gene transfer from organelles, frequency and position of transposable elements, and evolutionary relationships. The task of sequencing an entire genome still remains formidable, however the relative ease and precision of sequencing and the efficiency of subsequent annotation and o...

The tomato (Solanum lycopersicum) fruit is an excellent source of antioxidants, dietary fibers, minerals and vitamins and therefore has been referred to as a “functional food”. Ripe tomato fruits produce a large number of specialized metabolites including volatile organic compounds. These volatiles serve as key components of the tomato fruit flavor, participate in plant pathogen and herbivore d...

Understanding the development of a complex structure such as a fruit provides both an interesting developmental model and an important task for agriculture, holding the potential of improving both product quality and human nutrition (Klee, 2010). For this task, the tomato (Solanum lycopersicum) fruit has proven a tractable model system, with complex metabolism and accessible genetics and genomi...

The activity of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) and the level of its mRNA have been determined at various stages of tomato fruit development. The HMGR reaction makes mevalonate, a necessary component in the synthesis of all isoprene containing compounds, such as sterols and carotenoids. A cDNA clone encoding the active site region of HMGR has been isolated from a tomato l...
