The wheat dehydrin DHN-5 represents one of the members of the LEA (Late Embryogenesis Abundant) group 2 family. It has been previously shown to play a fundamental role in plant response and adaptation to abiotic stresses. It has also exhibited heat-protecting effect on enzymatic activities. In the present work, we report a number of findings resulting from(More)
Much is now known about proline multifunctionality and metabolism; some aspects of its biological functions are still unclear. Here, we discuss some cases in the proline, structure, definition, metabolism, compartmentalization, accumulation, plausible functions and also its implication in homeostasis and organism physiology. Indeed, we report the role of(More)
The coat protein (CP) gene of the Potato virus Y common strain (PVYo), rendered untranslatable by introduction of a stop codon immediately after the initiation codon, was cloned into an Agrobacterium tumefaciens transformation vector. The regenerated transgenic tobacco plants were analyzed for the presence of the CP gene. Although transgene transcripts were(More)
The aim of this study was to compare immunogenic and toxic gluten peptides related to celiac disease (CD). 100 accessions of genotypes selected during the 20th century in Tunisia were in vitro digested and then analyzed by UPLC/ESI-MS technique using an isotopically labeled internal standard. The first MANOVA confirmed a high variability in the content of(More)
Durum wheat (Triticum turgidum ssp. durum) is one of the main species of cultivated wheat. In arid and semi-arid areas, salinity stress reduces durum wheat productivity. This study used 26 durum wheat accessions from semi-arid regions in Tunisia to analyze plant tolerance to salt stress. Salt stress was experimentally applied by regularly submerging pots in(More)
Baker's asthma is a serious airway disease triggered by wheat protein CM3 α-amylase/trypsin inhibitor. The purpose of the present study was to investigate the impact of genotype and crop year on allergen CM3 α-amylase/trypsin inhibitor associated with baker's asthma. A historical series of Tunisian durum wheat (100 accessions), derived from three crop(More)
