Self-incompatibility in the genus Prunus is controlled by two genes at the S-locus, S-RNase and SFB. Both genes exhibit the high polymorphism and high sequence diversity characteristic of plant self-incompatibility systems. Deduced polypeptide sequences of three myrobalan and three domestic plum S-RNases showed over 97% identity with S-RNases from other Prunus species, including almond, sweet cherry, Japanese apricot and Japanese plum. The second intron, which is generally highly polymorphic between alleles was also remarkably well conserved within these S-allele pairs.

Developmental timing genes catalyze stem cell progression and animal maturation programs across taxa. Caenorhabditis elegans DRE-1/FBXO11 functions in an SCF E3-ubiquitin ligase complex to regulate the transition to adult programs, but its cognate proteolytic substrates are unknown. Here, we identify the conserved transcription factor BLMP-1 as a substrate of the SCF(DRE-1/FBXO11) complex. blmp-1 deletion suppressed dre-1 mutant phenotypes and exhibited developmental timing defects opposite to dre-1.
