Summary

Tomato is considered one of the most economically important vegetable crops in the world, particularly in temperate areas. Abiotic stresses as those promoted by salt accumulation and water deficiency entail significant losses of productivity. Despite the great efforts for increasing tolerance in such species of agronomic interest as tomato, the results so far obtained both with conventional breeding methods and with some biotechnological approaches have been rather scarce due to the complexity of the response to salt and drought stress. Moreover, only a small number of genes playing important roles in tolerance mechanisms to drought and/or salinity have been identified so far. Thus, novel tomato genes involved in abiotic stress tolerance need to be isolated and functionally characterized to help increase the level of salt and drought tolerance by means of gene transformation. This chapter focuses on the applications of genomic tools to the genetic dissection of those complex traits in tomato and related halotolerant wild species. First, the opportunities and limitations of the genome-wide expression profiling approaches to identify the genes associated with the stress response are discussed. Likewise, the advances achieved through forward and reverse genetics approaches such as insertional and chemical mutagenesis, TILLING, and other gene tagging approaches are reviewed. Hopefully, the combined use of all these genomics tools will lead to important advances in the genetic and physiological mechanisms of tolerance to drought and salinity in tomato, thus allowing the proper design of future breeding programs.
