Abstract/Contents:"The uptake of 59Fe(II)SO4, 59Fe(III) phytosiderophores and the release of phytosiderophores (PS) in a Ni-tolerant mutant and its wild type of ryegrass (Lolium perenne L.) were examined. The results showed that the uptake rates of 59Fe2+ in the mutant were about 2-fold lower than those in the wild-type independently of the Fe nutritional status (+/- Fe preculture) and Ni supply levels. In contrast, the uptake rates for 59Fe(III)PS were higher in the mutant than in the wild-type, paticularly under Fe deficiency. The high Ni supply decreased 59Fe(III)PS uptake rate by 40% for the wild-type and by 20% for the mutant under Fe deficiency. However, the rate of PS release was significantly lower in the mutant than in the wild-type. These results indicated that the relatively high sensitivity of Ni-tolerant mutant to Fe deficiency is obviously due to a lower rate of Fe2+ uptake and PS release. Further studies are needed to understand the relationship, between uptake and translocation of Ni and acquisition and translocation of Fe within the mutant."
