Plant Biology: Distinct New Players in Processing Peptide Hormones during Abscission

Curr Biol. 2020 Jun 22;30(12):R715-R717. doi: 10.1016/j.cub.2020.04.072.


Flower organ abscission in Arabidopsis is regulated by a peptide hormone that is released from its precursor by a network of redundant subtilases. An exciting new study describes how drought-induced flower abscission in tomato is regulated similarly, but distinctly via a single, different subtilase that releases a very different peptide hormone.
