ISOLATION AND IDENTIFICATION OF KEY GENES CONTROLLING SALT TOLERANCE IN GREY MANGROVE (Avicennia marina) AL-NABQ PROTECTORATE, EGYPT.

The article highlights the study related to the isolation and identification of key genes controlling salt tolerance in grey mangrove. Topics discussed include information on the toxic effects of salt stress on the plants; discussions on the metabolic changes due to the salt stress in plants such as the loss of chloroplast activity, decreased photosynthetic rate and increase photorespiration rate; and the information on the importance of the antioxidant enzymes in dealing with salt stress.
