donor molecule
2.The research using two glycine betaine synthesis related genes namely Choline dehydrogenase (CMO) and Betain-aldehyde dehydrogenase (BADH) from Atriplex hortensis as donor, the japonica rice and some indica hybrid rice restorer or maintainer lines as receptor, gotsome transgenic plants by using micro-particle bombardment or agri-bacterium, and proved that the target gene have been integrated into the rice genome after molecule testing. And these gene modified rice express better salt tolerance.
3.The results of experiments show that the ion--molecule association reactions taken place in the case of no electroabstracting group on the aromatic ring, andthen the adduct ions LM+ArCOJ+ and [M+ArJ+ formed. The carbonyl oxygen servesas donor atoms in this type of association reaction.
