    ..In suf4 mutants, however, only FLC expression is suppressed. These data are consistent with a model in which SUF4 may act to specifically recruit EFS and the PAF1-like complex to the FLC locus. ..

    ..This finding lends support to the proposal, based on studies of irradiation-generated pollen-part mutants of solanaceous species, that duplication, but not deletion, of the pollen S, causes breakdown of pollen function...
