MIZU-KUSSEI1 (MIZ1)TropismRoot hydrotropism is the directional growth of roots toward a source of moisture in response to a water potential gradient. Root hydrotropism is therefore one of the most important factors for efficient water acquisition under water-limited conditions. However, the ...
Here, we employed the Arabidopsis ( Arabidopsis thaliana ) hydrotropism-specific protein MIZU-KUSSEI1 (MIZ1) as bait and found that calcium-dependent protein kinases 4/5/6/11 (CPK4/5/6/11) interacted with MIZ1 in vitro and in vivo. The cpk4/5/6/11 mutant exhibited increased sensitivity...
