WebJun 1, 2011 · Cytokinins (CKs) regulate plant growth and development via a complex network of CK signaling. Here, we perform functional analyses with CK-deficient plants to provide direct evidence that CKs negatively regulate salt and drought stress signaling. WebJan 1, 2012 · Cytokinins are defined as substances stimulating (at the presence of auxin) cell division (cytokinesis) ( 3 ). They are indispensable for cell cycle transition at both check points—G 2 /M and G 1 /S ( 4 ). They positively affect photosynthesis ( 5 ), delay senescence, and enhance the sink strength ( 6 ).
