In: Egyptian Journal of Genetics and Cytology 2010.v.39(1)Summary: Abscisic acid (ABA), a plant growth hormone, is synthesized through the carotenoid biosynthetic pathway (Xiong et al., 2002). In 1963, the role of abscisic acid was first identified and characterized by Addicott et al. (1968). ABA plays a key role in many physiological and developmental processes such as water relations, seed dormancy and germination (Kermode, 2005). Environmental challenges such as freezing, water stress caused by either high osmotic, salt or drought and wounding increase endogenous ABA levels in plant cells (Thaler and Bostock, 2004). Content of endogenous abscisic acid (ABA) is increased in rice plants under salt stress (Seo et al., 2005). Vicia villosa is one of the Vicia sp. found in the north coastal region of Egypt, as well-known desert with its difficult climate. So, it is considered a good genetic pool for studying and isolating stress-related genes. This species is a weak-stemmed climbing annual and winter active legume (Aly and Hassan, 1993).
