Abstract

Several hypotheses concerning consequences of selenium deficiency on iodine metabolism can be proposed on the basis of experimental studies in rats and from epidemiological and experimental studies in humans. By decreasing intracellular GSH peroxidase activity, selenium deficiency may increase hydrogen peroxide ([H.sub.2][O.sub.2]) supply and lead over several weeks to the thyroid atrophy observed in myxoedematous cretins. By improving thyroid hormone synthesis and by decreasing peripheral thyroxin ([T.sub.4]) deiodination, selenium deficiency could protect fetal brain [T.sub.4] Supply and thus prevent neurologic cretinism. Selenium deficiency may protect against iodine deficiency by decreasing [T.sub.4] metabolism--and thus iodide leakage and--perhaps also by increasing [H.sub.2][O.sub.2] supply and thyroid hormone synthesis and thus thyroid efficiency.

Abstract

10 p., Despite the high economic value of safflower (Carthamus tinctorius), the potential of several wild related species as genetic resources is still poorly studied, in particular with regards to drought tolerance, a priority in safflower improvement. This situation is partially explained by the numerous and still discussed uncertainties in phylogenetic relationships within the safflower species complex. In this study, we focused on two rare Algerian wild species, Carthamus strictus and Carthamus chouletteanus. We aimed at: (i) clarifying their taxonomic status, and determining their phylogenetic relationships with safflower and other Mediterranean species of Carthamus sensu lato (s.l.) (Carthamus sensu stricto (s.s.) and Carduncellus genera) by using nucleotide diversity within the internal transcribed spacer region (ITS) and (ii) assessing the water use efficiency (WUE) of these species by determining their carbon isotope composition. Our results support the existence of two well supported different clusters among the safflower species complex: Carthamus s.s. including Eastern annual species and the vast Carduncellus group constituted by Western perennial species, including the two studied Algerian species. Also, significant differences for carbon isotopic composition between Carthamus s.s. and Carduncellus were revealed. Carduncellus species displayed significantly higher δ13C values (i.e., higher WUE) than Carthamus s.s. species. Carthamus chouletteanus displayed the highest average value of δ13C (highest WUE) among the species studied. Our data encourage for further studies on the possibility of hybridisations between species of the two genera and suggest that Carduncellus should be considered as potentially more interesting genetic resources to improve the WUE of safflower, rather than Carthamus s.s. species., The authors gratefully acknowledge the Laboratory of Ecology, Systematics and Evolution at the University of Paris-Sud (Orsay, France) for funding the nucleotide sequences analysis and the isotopic analyses, the platform “Metabolism-Metabolome” of the IPS2 (Orsay, France) for completion of isotopic analyses, and the Technical Institute for Industrial and Vegetables Crops (ITCMI) Staouali (Algeria) for allowing the realisation of experiments in the field.
