DETERMINATION AND QUANTIFICATION OF SALT STRESS RELATED GENES IN FABA BEAN (Vicia faba)

Salt stress is one of the major environmental factor that affecting plant growth and development. High salt content in the soil causes accumulated stress to the cultivated plants in some areas. Plants may be modified genetically to tolerate these effects that lead to some physiological and morphological modification too (Shanon, 1986; Fisher and Turner, 1978). These interacted changes and modifications are not that simple and a lot of response pathways are required to overcome the unfavorable conditions (Neumann, 1997; Yao, 1998; Hasegewa et al., 2000; Munns, 2002). In salty habitat, some plants tolerate these effects and grow in full capacity. These plants have a unique genetic profile tolerating the crucial environment. Bad drainage and high temperature are affecting the agricultural lands that lead to accumulation of salt in the soil (Zhu et al., 2005). These problems are common in most of eastern and southern Mediterranean Sea countries including Syria, Lebanon, Jordan, Egypt, Libya, Tunisia, Algeria and Morocco. In Egypt, bad drainage has bad environmental impacts in the north of Nile delta and the west north coast (FAO, 2005).
