Conclusions and outlook 911Acknowledgements 912References 912Summary Subtilases ( SBT s) are serine peptidases that are found in all three domains of life. As compared with homologs in other Eucarya , plant SBT s are more closely related to archaeal and bacterial SBT s, with which they share many biochemical and structural features. However, in the course of evolution, functional diversification led to the acquisition of novel, plant‐specific functions, resulting in the present‐day complexity of the plant SBT family. SBT s are much more numerous in plants than in any other organism, and include enzymes involved in general proteolysis as well as highly specific processing proteases. Most SBT s are targeted to the cell wall, where they contribute to the control of growth and development by regulating the properties of the cell wall and the activity of extracellular signaling molecules. Plant SBT s affect all stages of the life cycle as they contribute to embryogenesis, seed development and germination, cuticle formation and epidermal patterning, vascular development, programmed cell death, organ abscission, senescence, and plant responses to their biotic and abiotic environments. In this article we provide a comprehensive picture of SBT structure and function in plants.
