Excited to see my latest project finally published! 🎉 We identified BSK proteins as regulators of IDA signaling and abscission 🍃. Our genetic work also points at a generalized mode of action for BSK1 across RLK pathways (HAE, FLS2, ERECTA, BRI1). www.cell.com/current-biol... #PlantScience

A multifaceted kinase axis regulates plant organ abscission through conserved signaling mechanismswww.cell.com Galindo-Trigo et al. show that BSK1 and BSK2 regulate floral organ abscission in Arabidopsis. BSK1 localizes to the plasma membrane and interacts with HAE/HSL2. A hypermorphic allele of BSK1 activates...
