  Dominance in self-compatibility between subgenomes of allopolyploid Arabidopsis kamchatica shown by transgenic restoration of self-incompatibility

  Self-incompatibility in diploid Arabidopsis relatives is determined by a dominance relationship that is epigenetically regulated. Using transgenic methods, this study demonstrates that the dominance relationship between subgenomes of the allopolyploid species Arabidopsis kamchatica underlies it’s self-compatibility.

  Breakdown of self-incompatibility due to genetic interaction between a specific S-allele and an unlinked modifier

  Breakdown of self-incompatibility in plants is often attributed to S-locus mutations. Here, by crossing between populations of Arabidopsis lyrate that differ in their breeding system, the authors propose that a modifier unlinked to the S-locus causes self-compatibility by disrupting S-locus function.

  VviPLATZ1 is a major factor that controls female flower morphology determination in grapevine

  Unlike wild Vitis species, which produce either female or male flowers, modern grapevine cultivars form hermaphrodite flowers for self-pollination. Here, the authors report that the VviPLATZ1 (plant AT-rich sequence-and zinc-binding protein1) transcription factor functions in controlling female flower morphology determination.

  A nonS-locus F-box gene breaks self-incompatibility in diploid potatoes

  Diploid potatoes are typically self-incompatible, complicating efforts to breed diploid cultivars. Here the authors report map-based cloning of the S-locus inhibitor (Sli) gene in potato which encodes a non S-locus F-box protein that is expressed in pollen and can functions like a general S-RNase inhibitor to overcome self-incompatibility.

  Neofunctionalisation of the Sli gene leads to self-compatibility and facilitates precision breeding in potato

  The S-locus inhibitor (Sli) gene could allow potato breeding by facilitating production of diploid inbred lines. Here the authors show that Sli encodes an F-box protein with a promoter insertion enhancing expression in pollen can overcome pollen rejection in the styles of diploid potato.

  Mechanism of self/nonself-discrimination in Brassica self-incompatibility

  Self-incompatibility responses in Brassica are induced by haplotype-specific interactions between the pistil-expressed SRK receptor and pollen-expressed SP11 ligand. Here, via crystal structures and molecular dynamic simulations, the authors provide a model to explain why binding of cognate partners is favoured and how haplotypes can be distinguished.

  Parallel evolution of dominant pistil-side self-incompatibility suppressors in Arabidopsis

  In Brassicaceae, interaction between the pollen-derived peptide ligand SP11 and the pistil-expressed receptor kinase SRK leads to self-incompatibility. Here the authors provide evidence that in Arabidopsis dominant self-compatibility inducers evolved at least twice via insertion of inverted repeats in the SRK locus.
