Jul 20, 2005Molybdenum is a trace element found in the soil and is required for growth of most biological organisms including plants and animals. Molybdenum is a transition element, which can exist in several oxidation states ranging from zero to VI, where VI is the most common form found in most agricultural soils.
ContactMolybdenum is utilized by selected enzymes to carry out redox reactions. Enzymes that require molybdenum for activity include nitrate reductase, xanthine dehydrogenase, aldehyde oxidase and sulfite oxidase. Scope: Currently, there is little information on how plants access molybdate from the soil solution and redistribute it within the plant.
ContactFunction of molybdenum Molybdenum is an essential component in two enzymes that convert nitrate into nitrite (a toxic form of nitrogen) and then into ammonia before it is used to synthesize amino acids within the plant. It also needed by symbiotic nitrogen fixing bacteria in legumes to fix atmospheric nitrogen. Click to see full answer
ContactMolybdenum 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 (NO3‑) they can't process it and use it for it's intended purpose (to make amino acids and proteins for instance).
ContactThe functions of molybdenum in plants and other organisms are related to the valence changes that it undergoes as a metallic component of enzymes (9). With the exception of bacterial nitrogenase, molybdenum-containing enzymes in almost all organisms share a similar molybdopterin compound at their catalytic sites (7,8).

ContactJan 01, 2018Molybdenum is among the mineral elements essential for the growth and development of plants. Macronutrient availability often impacts the growth and yield in crop plants, but the efficiency in obtaining micronutrients such as Mo might have also important effects on plant productivity ( Mei et al., 2009 ).

The requirement of molybdenum for plant growth was first demonstrated by Arnon and Stout (1939) using hydroponically grown tomato. Plants grown in nutrient solution without molybdenum developed characteristic phenotypes including mottling lesions on the leaves,
ContactBackground: The importance of molybdenum for plant growth is disproportionate with respect to the absolute amounts required by most plants. Apart from Cu, Mo is the least abundant essential micronutrient found in most plant tissues and is often set as the base from which all other nutrients are compared and measured.
ContactDec 21, 2020Sandy soils and acidic soils contain less available molybdenum for plant growth. The element is crucial to the functions of nitrogenase and nitrate reductase, two enzymes important for nitrogen fixing and nitrogen reduction. Not all plants need the same amount of molybdenum. Plants like cruciforms and legumes need higher amounts of the mineral.

ContactJan 01, 2018Molybdenum is present in soils at amounts high enough (0.2-6.0 mg Kg − 1) to support its needs in plants where it appears as one of the scarcest transition elements (He et al., 2005, Kaiser et al., 2005).
