Cadmium (Cd) can stress plants by affecting various physiological functions. Cd stress-response mechanisms were investigated in two genotypes of domesticated safflower (Carthamus tinctorius) and a population of wild safflower (Carthamus oxycantous) to explore potential differences in tolerance mechanisms of these species. A hydroponic experiment was conducted with 6-day-old safflower plants. Genotypes AC-Sterling (tolerant) and Saffire (semi-tolerant) from C. tinctorius, and Arak (sensitive) a population from C. oxycantouswere subjected to three concentrations of Cd (i.e., 0, 1, and 20 µM CdCl). Genotypic differences were detected in Cdtolerance index, Cd concentration in shoots and roots, Cd translocation to shoots, Cd bound to cell walls, superoxide dismutase (SOD) activity, lipid peroxidation, and phytochelatins accumulation in safflower plants upon exposure to CdCl. Results indicate that genotypic differences were more obvious in the presence of low (i.e., 1 µM) rather than high (i.e., 20 µM) CdCl concentrations. Comparing genotypes, root and shoot Cd accumulation was highest in the semi-tolerant genotype. Cadmium translocation to shoots was increased with increasing tolerance. The percentage of Cd bound to root cell walls was higher in the tolerant genotype, but only with low CdCl addition. Furthermore, in the tolerant genotype, SOD activity was lowest in both roots and shoots with low CdCl addition but highest with high CdCl addition, while the opposite was found for phytochelatins. Lipid peroxidation was decreased with Cd tolerance at both CdCl concentrations. We conclude that safflower relies mainly on binding Cd to the cell walls and the formation of phytochelatins in root and shoot tissues, in order to handle the Cd stress, evidenced by lessening Cd-induced lipid peroxidation.

An oily liquid extracted from the seeds of the safflower, Carthamus tinctorius. It is used as a dietary supplement in the management of HYPERCHOLESTEROLEMIA. It is used also in cooking, as a salad oil, and as a vehicle for medicines, paints, varnishes, etc. (Dorland, 28th ed & Random House Unabridged Dictionary, 2d ed)

Infection by round worms of the genus TOXOCARA, usually found in wild and domesticated cats and dogs and foxes, except for the larvae, which may produce visceral and ocular larva migrans in man.
Animals considered to be wild or feral or not adapted for domestic use. It does not include wild animals in zoos for which ANIMALS, ZOO is available.
The only extant family of the suborder Tylopoda (order Artiodactyla). Currently living members include domesticated species, DROMEDARIES (with one-hump); BACTRIAN CAMELS (with two humps); LLAMAS; ALPACAS, and wild feral camels; VICUNAS; and GUANACOS. Although they get nutrients from plants by rumination, they evolved separately from the RUMINANTS which have four-chambered stomachs. Camelidae have three-chambered stomachs.
