Summary

Apical maximal acidity (shown by subapically increasing pH) and maximal concentration of inorganic phosphate (shown by a subapically decreasing gradient of yellow phosphomolybdate) contrast with the subapical, mainly mitochondrial sequestration of calcium ions. Such gradiential control of calcium concentration appears to be the requisite for the Ca++ sensitive gelation of the apical hyaloplasm preventing the mitochondria from entering into this continuosly elongating zone of growing hyphae.
