To make sure the health of your plants and your yields are maximized in 2020, let’s do a quick refresher on molybdenum (Mo or abbreviated as “Moly”). Molybdenum deficiency or toxicity is not very common, but its deficiency is seen more frequently in poinsettias. Molybdenum (Mo) deficiency occurs when plant growth is limited because the plant cannot take up sufficient quantities of this essential micronutrient from its growing medium.
If insufficient molybdenum is available nodulation will be … Molybdenum is essential to plant growth as a component of the enzymes nitrate reductase and nitrogenase. Molybdenum in plants and soils. In this review, the role of molybdenum in plants is discussed, focusing on its current constraints in some agricultural situations and where increased molybdenum nutrition may aid in agricultural plant development and yields. Ann. The role of molybdenum in agricultural plant production. 96 745–754 10.1093/aob/mci226 [PMC free article] Kannan S., Ramani S. (1978). (A) The molybdenum cofactor biosynthetic pathway starts with the conversion of GTP into cPMP in the mitochondria. The effect of Mo in sand cultures was evident only in grain yield; in soil cultures the element was ineffective. Molybdenum is an essential trace element for several enzymes important to animal and plant metabolism: mammalian xanthine oxidase/xanthine dehydrogenase, aldehyde oxidase, sulfite oxidase, formate dehydrogenase, nitrate reductase and nitrogenase. Legumes need more molybdenum than other crops, such as grass or corn, because the symbiotic bacteria living in the root nodules of legumes require molybdenum for the fixation of atmospheric nitrogen. Molybdenum is a plant micronutrient.Molybdenum is only required in very small amounts but it is important for nitrogen metabolism; without molybdenum, plants may be able to take up nitrogen but if it's in the form of a nitrate (NO 3 ‑) they can't process it and use it for it's intended purpose (to make amino acids and proteins for instance).
Plants also use molybdenum to convert inorganic phosphorus into organic forms in the plant. The Role of Molybdenum in Agricultural Plant Production BRENT N. KAISER*, KATE L.

Legumes need more molybdenum than other crops, such as grass or corn, because the symbiotic bacteria living in the root nodules of legumes require molybdenum for the fixation of atmospheric nitrogen. PHYSIOLOGICAL ROLE OF MOLYBDENUM IN PLANTS Molybdenum is a component of at least five distinct enzymes that catalyze diverse and unrelated reactions, namely nitrogenase, nitrate reductase, xanthine oxidase, aldehyde oxidase, and sulfite oxidase (Nicholas, 1975).
Without molybdenum, plants may be able to take up inorganic phosphorus but they will struggle to convert that phosphorus into an organic form that they can use. Molybdenum in Biology - An Essential Trace Element Essential role of molybdenum. Molybdenum is an essential mineral in the body, just like iron and magnesium.
Plant Physiol. Molybdenum in plants and soils. Molybdenum. Bot.
Molybdenum is vital for the process of symbiotic nitrogen (N) fixation by Rhizobia bacteria in legume root modules. Molybdenum in Biology - An Essential Trace Element Essential role of molybdenum. Currently, there is little information on how plants access molybdate from the soil solution and redistribute it within the plant. Rare Deficiency Considering Mo’s importance in optimizing plant growth, it’s fortunate that Mo deficiencies are relatively rare in most agricultural cropping areas. AGFACTS AGFACTS www.dpi.nsw.gov.au ORDER NO. For crops growing in soil, this may be a result of low concentrations of Mo in the soil as a whole (i.e. Molybdenum (Mo), the last of the required micronutrients, is needed in the smallest quantities by plants.
