Target-Cell Contact Activates a Highly Selective …

Cells that responded to JYs also released less Ca 2+ when treated with TG than cells in the same experiment that did not respond to targets (data not shown). These results confirm that contact with JY targets releases Ca 2+ from the TG-sensitive Ca 2+ stores that control CCE, which is consistent with the idea that CCE participates in the response to target cells.

Calcium: A Central Regulator of Plant Growth and …

EARLY STUDIES ON PLANT CALCIUM Ca 2+ is an essential element; however, its role is elusive. When examining total Ca 2+ in plants, the concentration is quite large (mM), but its requirement is that of a micronutrient (μM). Ca 2+ is not usually limiting in field conditions, still there are several defects that can be associated with low levels of this ion, including poor root development, leaf
