What is the role of Molybdenum in aquatic plant biology?
It seems to be the largest atom used by plants. Interestingly for such a
large atom, it is a mobile nutrient.
A reference at <http://184.108.40.206/TechBulletins/NutrientFncts2.PDF>
states: "Molybdenum (Mo) is taken up by plants as the molybdate ion (MoO4=).
It is required by plants for the utilization of nitrogen. Nitrate nitrogen
is converted to amino acids by the nitrate reductase enzyme; this enzyme
requires molybdenum. In addition, molybdenum is required for the symbiotic
fixation of nitrogen by legumes."
Another useful reference
"Nitrogen metabolism, protein synthesis and sulfur metabolism are also
affected by molybdenum."
"Molybdenum is essential to plant growth as a component of the enzymes
nitrate reductase and nitrogenase [Sequi, 1972; Ivanova, 1972; Childers and
Borys, 1962; Albrigo et al., 1966; Reisenower, 1971]."
reference contains a lot of information about Mo enzymes.
I guess I answered my own question :%)
