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.
