| Research Abstract |
Uniparental inheritance of mitochondrial (mt) and chloroplast (cp) DNA is a phenomenon common to diverse taxa of plants and animals. Uniparental inheritance was long thought to be a passive outcome, based on the fact that eggs contain multiple numbers of organelles, while the contributions from male gametes are limited. However, it is likely to be more dynamic process, including the active digestion of male mt/cpDNA. In this project, Chlamydomonas mutants defective in uniparental inheritance of cpDNA were obtained and analyzed, which revealed that a homeotic gene that regulate the sexual development is also a key factor for uniparental inheritance.
