HAESA and HSL2 are receptors for IDA/IDL-family signaling peptides in plants. Here the authors show that HSL1, previously shown to recognize CLE9, preferentially binds IDA/IDL peptides and regulates leaf epidermal patterning independently of CLE pept

Significance Plant reproduction relies on proper pollen tube growth to reach the female gametes. This process is highly regulated by a family of secreted signaling peptides that are recognized by cell-wall monitoring proteins to enable plant fertiliz

Multicellularity arose independently in plants and animals, but invariably requires a robust determination and maintenance of cell fate that is adaptive to the environment. This is exemplified by the highly specialized water- and nutrient-conducting

Understanding the context-specific role of gene function is a key objective of modern biology. To this end, we generated a resource for inducible cell type-specific transactivation in Arabidopsis ( Arabidopsis thaliana ) based on the well-established
