Notes

[back to top]


  • The rho gene is often misannotated as a polarity suppressor. Mutations in rho suppress polarity.[5][6][7][8][9] Wild type rho is the source of polarity.
  • rho has been shown to be an essential gene (Das, 1976; Bubunenko, 2007).[4]
  • rho is required to maintain genomic integrity by resolving transcription/replication conflicts [10]
