- Abstract
The shedding, or abscission, of plant organs occurs in four stages at specialized junctions in the plant called abscission zones (AZs). Premature abscission can pose a problem for farmers by reducing crop yield. Studies in Arabidopsis thaliana have identified organ boundary genes BLADE-ON-PETIOLE1/2 (BOP1/2) as essential for the formation of AZs. However, downstream effectors of BOP1/2 in this process are unknown. To execute developmental programs in inflorescences, BOP1/2 require TGA basic leucine zipper transcription factors for recruitment to DNA and TALE homeodomain proteins ATH1 and KNAT6 for boundary patterning. How these factors contribute to abscission is unclear. Here, I show that TGA and TALE transcription factors contribute to BOP-dependent formation of AZs. I also begin to explore a role for this module in organ separation. Collectively, my work reveals a role for boundary genes at different steps of abscission for potential application in crops.
