Precise control of falling flowers and fruits is a key part of improving quality and efficiency

Abstract: The strategic implementation of measures to minimize and optimize the timing of fruit drop plays a critical role in enhancing both quality and efficiency. Recent studies in Arabidopsis have substantiated the role of a complex kinase axis, centered on BR-SIGNALING KINASE 1 (BSK1), which regulates organ abscission in plants. These findings revealed that BSK proteins may act as scaffolds for assembling HAESA/HAESA-LIKE2 (HAE/HSL2) and YODA (YDA), facilitating YDA activation by plasma membrane receptors. Once activated, YDA initiates the mitogen-activated protein kinase (MAPK) phosphorylation cascade, which ultimately triggers abscission. Furthermore, research suggests that this process involves a diverse range of transcriptional regulatory mechanisms. The findings of this study offer valuable insights for investigating similar processes in other crops, significantly advancing the field of plant abscission research.
