“…The STR and SPAD values showed significant correlation (r = 0.8423**). QTL analysis revealed a major salt-tolerant QTL on linkage group N where a salt-tolerance QTL had been previously reported in the cultivated soybean (Lee et al 2004). This QTL accounted for 68.7% of the total variance of the STR scale and 49.6% of the total variance of the SPAD values (Table 1 and Fig.…”

“…SSR markers from a genomic region on linkage group N, where a major QTL was detected by Lee et al (2004), were tested for polymorphism between the two parents and 7 polymorphic SSR markers were subsequently identified. Sequence information of the SSR markers was based on the study by Song et al (2004).…”

“…Abel (1969) reported that Cl exclusion is controlled by a single dominant gene, Ncl., however, the genomic location of the Ncl gene has not been determined. Lee et al (2004) evaluated 106 F 2:5 recombinant inbred lines (RIL) derived from a cross between soybean cultivars S-100 (salt-tolerant) and Tokyo (salt-sensitive) for salt tolerance in a saline field and a greenhouse. They identified one major quantitative trait locus (QTL) associated with salt tolerance around SSR markers Sat-091, Satt339, and Satt237 on linkage group N, and assumed that the major QTL might be the Ncl locus reported by Abel (1969).…”

In the present study, we investigated salt tolerance heredity in wild soybean, Glycine soja Sieb & Zucc., and compared the salt tolerance quantitative trait locus (QTL) of G. soja with that of Glycine max (L.) Merr. An F 2 population (n = 225) derived from a cross between the salt sensitive soybean cultivar Jackson (PI548657) and a salt-tolerant wild soybean accession (JWS156-1) was used. Evaluation of salt tolerance in the seedling stage was carried out in hydroponic culture with half-strength Hoagland and Arnon nutrient solution containing 120 mM NaCl. Visual ratings of symptoms based on leaf scorching and chlorophyll content (SPAD value) were taken for each plant 20 days after salt treatment. Both traits showed continuous distribution; however, salt-tolerant plants (i.e. plants with a high salt tolerance rating (STR) and SPAD value) were predominant. QTL analysis revealed a major salt-tolerant QTL with a large dominant effect, which accounted for 68.7% of the total variance of the STR scale, on the soybean linkage group N. Our results indicated that the salt tolerance QTL confers a large dominant effect over salt sensitivity and that the salt tolerance QTL is conserved in both wild and cultivated soybeans.

“…According to FAO (2008), there are at least 800 million hectares land subjected to salinity in the world, accounting for as much as 6% of the world's total land area. Although some of the salt-affected influences are the result of the natural causes, the considerable rest is derived from the degraded cultivated agricultural land (Lee et al, 2004;Munns & Tester, 2008). At present, the world's cultivated land affected by salinity has achieved 20% (Rhoades & Loveday, 1990).…”

The increasing seriousness of salinization aggravates the food, population and environmental issues. Ameliorating the salt-resistance of plants especially the crops is the most effective measure to solve the worldwide problem. The salinity can cause damage to plants mainly from two aspects: hyperosmotic and hyperionic stresses leading to the restrain of growth and photosynthesis. To the adverse effects, the plants derive corresponding strategies including: ion regulation and compartmentalization, biosynthesis of compatible solutes, induction of antioxidant enzymes and plant hormones. With the development of molecular biology, our understanding of the molecular and physiology knowledge is becoming clearness. The complex signal transduction underlying the salt resistance is being illuminated brighter and clearer. The SOS pathway is the central of the cell signaling in salt stress. The accumulation of the compatible solutes and the activation of the antioxidant system are the effective measures for plants to enhance the salt resistance. How to make full use of our understanding to improve the output of crops is a huge challenge for us, yet the application of the genetic engineering makes this possible. In this review, we will discuss the influence of the salt stress and the response of the plants in detail expecting to provide a particular account for the plant resistance in molecular, physiological and transgenic fields.
