Desert plants are exposed to a combination of environmental stress conditions, including water deficit, high temperature and high irradiance. We focused on antioxidative protection systems of C4 desert plant Haloxylon ammodendron and C3 desert plant Hedysarum scoparium within arid dune ecosystem with artificial controlling water availability. The activities of antioxidative enzymes (SOD, POD an...

The prominent feature of rhizobia is their molecular dialogue with plant hosts. Such interaction is enabled by the presence of a series of symbiotic genes encoding for the synthesis and export of signals triggering organogenetic and physiological responses in the plant. The genome of the Rhizobium sullae type strain IS123T nodulating the legume Hedysarum coronarium, was sequenced and resulted i...

Desertification is a global environmental problem, and arid dunes with sparse vegetation are especially vulnerable to desertification. One way to combat desertification is to increase vegetation cover by planting plant species that can realize fast population expansion, even in harsh environments. To evaluate the success of planted species and provide guidance for selecting proper species to st...

Poor growth during parasitic infection may be due to a redistribution of amino acids away from skeletal muscle protein synthesis to the intestinal site of infection. The effect of a Trichostrongylus colubriformis infection on whole-body amino acid kinetics and tissue fractional protein synthesis rates were determined in lambs fed fresh Sulla (Hedysarum coronarium; 800 g DM/d). Lambs were dosed ...

Samples of unifloral sulla (Hedysarum coronarum L.) honey from Sardinia (Italy) were analysed. To investigate the chemical composition of the honey volatiles two solvent systems were used for ultrasonic solvent extraction (USE): 1) a 1:2 (v/v) pentane and diethyl ether mixture and 2) dichloromethane. All the extracts were analysed by GC and GC/MS. These procedures have permitted the identificat...

Sulla genus (Hedysarea) includes six Mediterranean species constituting an important phytogenetic patrimony primarily used to promote feed production chiefly in arid and semi arid regions. In order to perform a phylogenetic analysis of Sulla species, both morphological and molecular data were used. The morphological data was comprised of 10 characters, while the molecular characters were compri...
