| Outline of Final Research Achievements |
To reveal the biological function of soybean PEX1, I focused on the homologues of PEX1 in Arabidopsis, AtPEX1a, AtPEX1b and AtPEX1c, and planned to conduct functional analysis of AtPEX1s. Although single mutation in AtPEX1a,b,c did not show any detectable phenotypes, Atpex1ab double mutant significantly accumulated starch in their shoots. On the other hand, overexpression of AtPEX1a or b did not affect shoot starch accumulation.
