The effect of sulphate concentration on the uptake and incorporation of [35S]sulphate in Chondrus crispus
Keyword(s):
The effect of different sulphate concentrations (2 × 10−5 to 10−2 M) in the labelling medium on [35S]sulphate uptake and incorporation into National Research Council of Canada gametophytic strain T4 Chondrus crispus has been investigated. Sulphate uptake appears to be multiphasic as in higher plants. An apparent Km for sulphate uptake has been determined over the range of concentrations 10−4 to 10−2 M. Sulphate incorporation is also altered at different sulphate concentrations.
