Abstract
The synthesis of organic compounds is necessary for growth of the plant bodies and survival of the heterotrophic organisms. Chloroplasts have their own genome which encodes a small proportion of the components required for their function. Chloroplasts have developed their own complex system to regulate gene expression in response to environmental signals and their developmental state.
Chloroplast/plastids have unique elliptical structure. Only some proteins are reported to concern determination of the size of plastids through plastid devision or protein import system. Few have been known about molecular mechanism of plastid biogenesis. We are studying mutants including variegation and white cotyledonous phenotypes, that will provide insights to the mechanism controlling biogenesis and maintainance of structure of plastids. We will present some of new findings and discussion about them.
