abstract：:Using tissue blotting and immunocytolocalization, we have investigated the appearance and accumulation of polygalacturonase (PG) during tomato (Lycopersicon esculentum Mill.) fruit ripening. Results show that PG first appears in the collumella region followed by sequential appearance in the exopericarp and endopericar...

abstract：:A wide diversity of isoprenoids is produced in different plant compartments. Most groups of isoprenoids synthesized in plastids, and some produced elsewhere in the plant cell derive from geranylgeranyl diphosphate (GGPP) synthesized by GGPP synthase (GGPPS) enzymes. In Arabidopsis (Arabidopsis thaliana), five genes ap...
