Detailed explanation-1: -Molybdenum in Plants Within the plant, Mo is primarily used in the production of “molybdoenzymes” that regulate various plant functions. The most well known of these Mo-containing enzymes regulate nitrogen (N) nutrition. In non-legumes, Mo-enzymes regulate the conversion of nitrate into proteins (nitrate reductase).
Detailed explanation-2: -Molybdenum is vital for the process of symbiotic nitrogen (N) fixation by Rhizobia bacteria in legume root modules. Considering molybdenum’s importance in optimizing plant growth, it’s fortunate that Mo deficiencies are relatively rare in most agricultural cropping areas. Image: Molybdenum deficiency in wheat.
Detailed explanation-3: -Molybdenum acts in the assimilation of N in plants through the nitrate reductase enzyme. Mo also acts directly on the photochemical phase of photosynthesis through chlorophyll biosynthesis and stability of the photosynthetic apparatus.
