Genetic diversity is of primary importance, not only because it has been the substrate of natural selection, but also because it represents a reserve of alleles and phenotypes which may become useful in the future in view of unpredictable climatic and other environmental changes. Even though several studies have been presented on gene variation in widely different environments (1), few attempts have been made to correlate variability in the genes which are relevant to environmental stress responses with adaptation to these environments. Being important factors that affect the distribution and limits of the species, environmental stresses such as extremes of temperature, water deficiency, excess of salts, pollutants and pathogens induce, among other responses, the expression of specific genes and the accumulation of specific proteins (1).
