    ..Although there are clearly functional redundancies among related sub-family members, those redundancies cannot be inferred simply based on the amino acid identity of the family members. ..

    ..Taken together, our results suggest that UBP16 is involved in salt tolerance in Arabidopsis by modulating sodium transport activity and repressing cell death at least partially through modulating SMH1stability and activity. ..

    ..Our results indicate that cold stress responses in Arabidopsis are attenuated by a ubiquitination/proteasome pathway in which HOS1 mediates the degradation of the ICE1 protein. ..

    ..Our results imply that SUVR4 is involved in the epigenetic defense mechanism by trimethylating H3K9 to suppress potentially harmful transposon activity. ..

    ..Whereas transgenic plants expressing HisUb showed insignificant enrichment of ubiquitinated proteins, transgenic Arabidopsis lines expressing HisUbK48R gave a much better yield. ..

    ..The question of whether SUVR proteins act as both readers of monoubiquitinated H2B and writers of histone PTMs is discussed. ..

    ..These data suggest that the E3 ubiquitin ligase AtCHIP may function upstream of PP2A in stress-responsive signal transduction pathways under conditions of low temperature or in the dark. ..
