Webb11 apr. 2024 · Movement of Ca 2+ toward leaves and fruits can be performed in both apoplastic and symplastic pathways (White and Broadley 2003 ). Ca 2+ moves in xylem vessel in chelate form and its movement is considerably dependent on the transpiration rate. In fact, low Ca 2+ content in plant tissues is a consequence of low transpiration rate … Webb20 jan. 2024 · Calcium (Ca 2+) is a second messenger for plant cell surface and intracellular receptors mediating pattern-triggered and effector-triggered immunity (respectively, PTI and ETI).
