Outline of Final Research Achievements

Charophycean green algae are the closest living relatives to land plants. To understand how plant transcription factors (TFs) diversified in Charophycean algae, we investigated genome in a unicellular charophycean alga, Closterium peracerosum-strigosum-littorale complex. We found that 75% of "land plant-specific" TF families that not found in Chlorophycean algae present in Closterium genome. We also found a Closterium TF, named CpMinus1, only present in mating-type minus genome. Transformation analysis indicated that the CpMinus1 is responsible for the sex determination in Closterium.
