major terminal
5.The major results of this study are as follows:1 .polyethyleneglycol(PEG)-magnetite (PMP) consisting of magnetite particles and PEG with terminal carboxy or amino groups and dextran-magnetite particle (DMP) were prepared. Influence of preparation conditions on effective diameters of McAb-PMP and McAb-DMP nanoparticles was unanimous. The content of magnetite of McAb-PMP was luger than that of McAb-PMP.
6.The contents of major polypeptides of 21kD(LHCP Ⅰ) and 25kD(LHCP Ⅱ)in thylakoid membranes from the ear leaves were more than those from the terminal leaves. The characteristics of both supramolecular architecture and poly- peptide components are in favour of absorbing,transferring,distributing and conversing light (?) nergy in the course of photosynthesis of the ear leaves in maize.
