采用35 SO 42-示踪剂交换动力学的房室分析方法，对热带豆科植物Macroptiliumatropurpureum离体根和叶组织中的单向通量和房室含量进行了估算。在切下的根组织中，只有5%的硫酸盐穿过质膜被还原为有机形式，而在切下的叶组织中，约20%被还原。因此，有必要将实验过程中硫酸盐的代谢纳入房室模型
Compartmental analysis of 35 SO 4 2- tracer exchange kinetics has been used to estimate unidirectional fluxes and compartment contents in excised root and leaf tissue of the tropical legume, Macroptilium atropurpureum. In excised root tissue only 5% of the sulphate taken up across the plasmalemma was reduced to organic forms whereas in excised leaf tissue approximately 20% was reduced. It was necessary, therefore, to incorporate the metabolism of sulphate during the course of the experiment into the compartmental models
