TI  - MAA3 (MAGATAMA3) helicase gene is required for female gametophyte development and 
      pollen tube guidance in Arabidopsis thaliana.

AB  - The female gametophyte plays a central role in the sexual reproduction of 
      angiosperms. We previously isolated the maa3 (magatama3) mutant of Arabidopsis 
      thaliana, defective in development of the female gametophyte, micropylar pollen 
      tube guidance, and preventing the attraction of multiple pollen tubes. We here 
      observed that the nucleolus of polar nuclei is small, and that the fusion of 
      polar nuclei often did not occur at the time of pollination. The MAA3 gene 
      encodes a homolog of yeast Sen1 helicase, required for RNA metabolism. It is 
      suggested that MAA3 may regulate RNA molecules responsible for nucleolar 
      organization and pollen tube guidance.
