영문 초록

The relationship between ADP-glucose pyro-phosphorylase (AGP) activity and the characteristics of related pod setting in developing seed of soybean cv. Pung-sannamulkong, Iksannamulkong, Geumjeongkong #1 and Danpaheuk was studied. AGP activity during the accumulate of the majority of dry matter in all cultivars suggested that this enzyme might be associated with this process. At the Vn and R1 stages, AGP activity of full-grown leaves of Pungsannamulkong, Iksannamulkong, Geumjeongkong #1 was the highest and then decreased progressively. However AGP activity of Danpaheuk was the lowest and also had lower seed weight. So regulation of matter accumulation in developing soybean seeds may also depend on AGP activity. AGP capacities as expressed by AGP activity seem to have a good predicting value for the dry matter of leaf and seed at R1 to R5 stages in our series of R3 stage genotypes. Western blots probed with antibody specific to the subunit of potato AGP revealed a single 60KD immunoreactive band that changed in intensity during the growth cycle in association with changes in total AGP activity.
