Webb1 sep. 1990 · At present, the mechanisms of entry into the symplast and subsequent phloem transport of phosphonate are unknown. Phosphonic acid is negatively charged at physiological pH due to the pKa values of 1.3 and 6.7 of its hydroxyl groups (2), and so would not be expected to readily diffuse across the plasmalemma to enter the symplast.
