Abstract
The vesicle transport systems in eukaryotes were found as secretion pathway starts from endoplasmic reticulum (ER). In transport vesicles, COPI (coat protein I) and COPII (coat protein II) work in the transport system between ER and Golgi apparatus. COPII coated vesicle that consists of the small GTP-binding protein, Sar1p and two coat protein complexes, sec23p/24p complex and sec13p/31p complex, are working in the transportation from ER to golgi apparatus. In this research, we examine the function of COPII components in development of Arabidopsis thaliana.
In these COPII components, we carry out the analysis of homologs of sec31p (ATSEC31), sec13p (ATSEC13), sec23p (ATSEC23) and sec24p (ATSEC24) that each ATSEC31, ATSEC13, ATSEC23 and ATSEC24. There are two homologs for each ATSEC31 and ATSEC13, are seven homologs for ATSEC23 and are three homologs for ATSEC24. In this research, we carry out the analysis of expression and localization for these homologs.
