eLife assessment This manuscript presents valuable findings on the role of a plant peptide in coordinating developmental and immune responses signaling. The evidence supporting the claims, while mainly descriptive and somewhat limited due to the main conclusions being drawn from overexpression lines, is mostly solid. The findings are interesting, they align with existing models, and they are of relevance to plant pathologists and developmental biologists.

New Results doi: https://doi.org/10.1101/761346 Abstract The abscission of floral organs and emergence of lateral roots in Arabidopsis is regulated by the peptide ligand INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) and the receptor protein kinases HAESA (HAE) and HAESA-LIKE 2 (HSL2). During these cell separation processes, the plant induces defense-associated genes to protect against pathogen invasion.
