Abstract
SummaryCytokinins (CKs) are important plant hormones that regulate a variety of biological processes implicated in plant development and stress responses. Here, we summarize the most recent advances in discovering and characterizing the membrane transporters involved in long‐ and short‐distance translocation of CKs and their significance in CK signal activity. We highlight the discovery of PUP7 and PUP21 tonoplast‐localized transporters and propose potential mechanisms for CK subcellular homeostasis. Finally, we discuss the importance of subcellular hormone transport in light of the localization of histidine kinase receptors of CKs at the endoplasmic reticulum and plasma membrane.
