4. We propose a model where BSKs may act as signaling facilitators of the activated plasma membrane RLKs:

3. We found that BSK1 can be found in proximity of the abscission receptors HAE/HSL2 in the plasma membrane of abscission zones, and that YDA is necessary and sufficient to induce abscission.

2. Next, we genetically characterized BSK1, BSK2 and BSK3 as redundant positive regulators of floral organ abscission.

Here are some highlights:

1. An ems-mutagenesis screen on ida mutants and a mapping-by-sequencing approach identified a novel hypermorphic allele of BSK1 as the causative mutation for the abscission phenotypic reversion:

Very happy to see this part of my postdoc in
Melinka's lab out as a preprint! 🤩

We investigated how the transcriptional control of the IDA gene integrates many of the cues that can induce floral organ abscission 🌷🍃🍃
