“…Plant salinity resistance genes that present greater levels of tolerance towards salt stress, have been identified, isolated and transferred (for more detailed information see Kolodyazhnaya, 2009). To increase salt tolerance, the gutD gene of Escherichia coli was used to confer salt resistance in corn plants (Liu et al, 1999). It has also been demonstrated that transgenic tomato plants accumulating polyamines are capable to tolerate high temperature stress (Cheng et al, 2009).…”

R. García-Gonzáles, K. Quiroz, B. Carrasco, and P.D.S. Caligari. 2010. Plant tissue culture: Current status, opportunities and challenges. Cien. Inv. Agr. 37(3): 5-30. In the last two decades plant biotechnology applications have been widely developed and incorporated into the agricultural systems of many countries worldwide. Tissue culture tools have been a key factor to support such outcomes. Current results have allowed plant biotechnology and its products-including transgenic plants with several traits-to be the most assimilated technology for farmers and companies, representing several benefits such as: 125 millions ha of transgenic crops in 2008, the reduction of pesticides application by up to 9% in the last ten years, transgenic plants with a better nutritional quality, mass propagation of selected and healthy plants, and the production of proteins for industrial or therapeutic use. The rapid and extensive assimilation for this technology has improved the competences of the agricultural systems both in industrial and in developing countries, based on the proper application of research programs. Several theoretical and practical aspects supporting plant tissue culture applications, as well as the main results and current status of the technology are discussed in this review. The reader will find key elements to evaluate the potential of plant tissue culture tools for the development of agriculture, livestock, human health and nutrition, and human well being in general.

“…Crops with resistance to viruses, pathogenic bacteria and fungi, and nematode and insect pests are nearing release (for example, Murray et al, 2002;Sharp et al, 2002). Newer technologies include: improved crop resistance to limiting environmental factors such as drought, salinity and toxic metals (de la FuenteMartinez et al, 1997;Liu et al, 1999;Garg et al, 2002;Song et al, 2003); enhanced nutrient content (Goto et al, 1999;Lucca, 1999;Bovy et al, 2002), including nutriceuticals; pharmaceutical or 'pharm' crops (Thanavala et al, 1995;Stoger, 2000); crops that bioaccumulate toxins for use in soil remediation (Song et al, 2003); and crops that produce industrially useful products, such as starches and plastics.…”

“…Using these technologies, drought-resistant soybean varieties (De Ronde et al, 2001) have been created, as has rice that is both drought and salt tolerant (Garg et al, 2002). Salt-tolerant maize, tomatoes, oilseed rape, and tobacco have been engineered by Liu et al (1999), , and Singla-Pareek et al (2003), respectively. Plants genetically manipulated to withstand the high levels of aluminium typical of increasing soil acidity due to improper land management have also been created (de la Fuente-Martinez et al, 1997;de la Fuente-Martinez and Herrera-Estrella, 1999).…”

Since the first commercial release of a transgenic crop in 1994, the land area planted to these crops has expanded to over 90 million ha worldwide, with approximately 8.5 million farmers in 21 countries cultivating transgenic crops. Public apprehension has mounted apace. Concerns include: (i) the potential for gene flow into wild plant populations or soil organisms; (ii) adverse effects on non-target organisms; (iii) gene products or crop residues persisting in the environment with deleterious effects and, for insecticidal crops; (iv) resistance developing in target pest populations. Numerous studies on the environmental risks of transgenic crops are published. Gene flow to a crop's wild relatives has been demonstrated in the field; hence, the use of these crops is restricted to regions where wild relatives are not endemic. Gene flow to soil organisms is yet to be demonstrated under field conditions and is unlikely given the safeguards employed, but not impossible. The weight of the evidence suggests that there is little risk to non-target soil organisms, but reduced numbers of non-target beneficial insects have been reported with the use of insecticidal crops in some systems. Population effects on non-target insects associated with the use of insecticidal crops are significantly less extensive than those experienced using chemical pesticides, and it has yet to be determined if observed population changes are ecologically significant in these cropping systems. Resistance of target pests to insecticidal crops is possible and eventually likely, but after nearly a decade of use has yet to be detected under field conditions. Several strategies to reduce potential ecological impacts are either under development or near release. Ecological risks posed by new technologies under development and the need for in-country risk assessment and post-release monitoring are discussed.

“…A recently discovered halophytic plant species, Thellungiella halophila (also known as T. salsuginea), has emerged as a new model plant for the molecular elucidation of abiotic stress tolerance [77]. The gutD gene from Escherichia coli can also be used to provide salt tolerance [79]. A salt tolerance gene isolated from mangrove (Avicennia marina) has been cloned, and can be transferred to other crop plants [78].…”
