The alteration in gene expression that occurs in plants subjected to water shortage has been documented extensively (Skriver and Mundy, 19901, and gene cloning and sequencing has shed some light on the molecular processes that may protect cells from the harmful effects of osmotic stress (Bray, 1991, 1993). Since plant hormones such as ABA and jasmonate are in some cases capable of causing expre...
Salinity is one of the most brutal environmental stresses that hamper crop productivity worldwide Approximately 10% of the total land surface is salt affected and about 10 million hectare of agricultural land is lost annually due to salinization and water logging. This study was conducted to determine the ion exchanges in Halocnemum strobilaceum and Halostachys caspica in saline conditions. The...
Natural plants consist of a hierarchical architecture featuring an intricate network of highly interconnected struts and channels that not only ensure extraordinary structural stability, but also allow efficient transport of nutrients and electrolytes throughout the entire plants. Here we show that a hyperaccumulation effect can allow efficient enrichment of selected metal ions (for example, Sn...
Fatty acid methyl ester (FAME) extracts of four halophytic plants, viz. Arthrocnemum indicum, Salicornia brachiata, Suaeda maritima and Suaeda monoica belonging to the family Chenopodiaceae, were prepared and their composition was analyzed by GC-MS. The FAME extracts were also screened for antibacterial and antifungal activities. The GC-MS analysis revealed the presence of more saturated fatty ...
The distribution and abundance of high aquatic plants in the Gorganroud River was examined at five stations in four seasons (20 samples) over one year period during 2009-2010. We identified 21 species of aquatic plants from 21 genera, belonging to 9 families. These species were determined as 3 halophytic species (14.2%) and 18 high aquatic plants (85.7%).The highest species diversity was observ...
