Summary of results of genetic and reverse genetic analyses of Arabidopsis polyadenylation factor subunits
This table summarizes published results (from our labs and from other groups) of genetic and reverse genetic studies of plant polyadenylation factor subunits. It will be updated periodically, as new information becomes available.

homozygotes are embryo-lethal (insertion mutation) |

CPSF73(I) |
essential (insertion mutations) |
overexpression using the 35S promoter is lethal; over-expression with the "native" promoter results in male sterility |

CPSF73(II) |
essential (insertion mutations) hemizygous plants are defective in female gametogenesis |

CPSF30 |
not essential (insertion); insertion mutants are oxidative stress-tolerant, dwarfed |

FY |
essential (insertions); some mutant alleles situated near the 3' end of the gene are viable, show a delay in flowering time |
