“…Yet high soil salinity inhibits seed germination and plant growth, and causes reduction in crop yields (Dalton et al, 1997;Romero-Aranda et al, 2002). In this study, young tomato plants have been grown in the presence of increasing concentrations of NaCl, and a concentration-and time-dependent inhibition of vegetative growth has been observed, which was better shown by the reduction of the fresh weight of the plants; this was not been reported that this species lacks two enzymes required for GB biosynthesis (Goel et al, 2011). Nevertheless, exogenous application of GB to tomato plants improves their resistance to drought (Rezaei et al, 2012) and salinity (Chen et al, 2009;Heuer, 2003;Makela et al, 1998).…”

The effects of salt and water stress on growth and several stress markers were investigated in cherry tomato plants. Some growth parameters (stem length and number of leaves) and chlorophyll contents were determined every third day during plant growth, and leaf material was collected after 25 and 33 days of treatment. Both stresses inhibited plant growth; chlorophyll levels, however, decreased only in response to high NaCl concentrations. Proline contents largely increased in leaves of stressed plants, reaching levels high enough to play a major role in cellular osmotic adjustment. Despite reports indicating that tomato does not synthesize glycine betaine, the stress-induced accumulation of this osmolyte was detected in cherry tomato, albeit at lower concentration than that of proline. Therefore, it appears that the plants are able to synthesise glycine betaine as a secondary osmolyte under strong stress conditions. Total sugars levels, on the contrary, decreased in stress-treated plants. Both stress treatments caused secondary oxidative stress in the plants, as indicated by a significant increase in malondialdehyde (MDA) contents. Water stress led to an increase in total phenolics and flavonoid contents and a reduction of carotenoid levels in the leaves; flavonoids also increased under high salinity conditions.

“…As many independent studies on the tomato show, plant regeneration achieved through organogenesis is affected by several factors such as genotype, explant source, age of explants, media composition and environmental conditions (Mamidala and Nanna 2011;Namitha and Negi 2013;Sherkar and Chavan 2014;Wayase and Shitole 2014). There are many reports regarding tomato transformation and in vitro plant regeneration from different explants (including seed-cut cotyledons, hypocotyls, leaves, stem sections, pedicels, petioles and inflorescences) via organogenesis (Khoudi et al 2009;Yasmeen 2009;Goel et al 2011;Koleva Gudeva and Dedejski 2012;Rai et al 2013;Namitha and Negi 2013;Sherkar and Chavan 2014;Wayase and Shitole 2014). These reports also describe the recalcitrance of 'non-competent' tomato explants (partial or total inability to respond to in vitro culture) (Fuentes et al 2008;Mamidala and Nanna 2011).…”

“…Hence, numerous researchers focused on one or a few genetic changes to modify key metabolites (e.g. glycine betaine and proline) (Goel et al 2011;Á lvarez-Viveros et al 2013) or proteins Late Embryogenesis Abundance (LEA) (Muñoz-Mayor et al 2012) for drought resistance. Another strategy to increase the level of drought and salinity tolerance in plants consists of a transfer of genes encoding different types of proteins involved in molecular responses to abiotic stress such as osmoprotectants, chaperones, detoxifying enzymes, transcription factors, signal transduction proteins (kinases and phosphatases) and heat-shock proteins (HSPs) Mishra et al 2012;Li et al 2013).…”

Originating in the Andes, the tomato (Solanum lycopersicum L.) was imported to Europe in the 16th century. At present, it is an important crop plant cultivated all over the world, and its production and consumption continue to increase. This popular vegetable is known as a major source of important nutrients including lycopene, bcarotene, flavonoids and vitamin C as well as hydroxycinnamic acid derivatives. Since the discovery that lycopene has anti-oxidative, anti-cancer properties, interest in tomatoes has grown rapidly. The development of genetic engineering tools and plant biotechnology has opened great opportunities for engineering tomato plants. This review presents examples of successful tissue culture and genetically modified tomatoes which resistance to a range of environmental stresses improved, along with fruit quality. Additionally, a successful molecular farming model was established.
