Analysis of salt-induced mRNA transcripts in tunisian local barley (hordeum vulgare) leaves identified by differential display RT-PCR

摘要

Salinity is one of the most serious factors limiting the productivity of agricultural crops, with adverse effects on germination, plant vigor, and crop yield (Munns and Tester 2008). Salinization affects many irrigated areas mainly due to the use of brackish water. Worldwide, more than 45 million ha of irrigated land have been damaged by salt, and 1.5 million ha are taken out of production each year as a result of high salinity levels in the soil (Munns and Tester 2008). High salinity affects plants in several ways: water stress, ion toxicity, nutritional disorders, oxidative stress, alteration of metabolic processes, membrane disorganization, reduction of cell division and expansion, and genotoxicity (Munns 2002; Zhou et al. 2012). Together, these effects reduce plant growth, development, and survival.
