NEET BIOLOGY

Detailed explanation-1: -Causes. Molybdenum cofactor deficiency is caused by mutations in the MOCS1, MOCS2, or GPHN gene. There are three forms of the disorder, named types A, B, and C (or complementation groups A, B, and C).

Detailed explanation-2: -High levels of Zn, Mn, K, chlorides are also among the causes of nitrogen deficiency in plants. Soil salinity negatively impacts nutrient absorption due to osmotic pressure and decreases N access.

Detailed explanation-3: -Necrosis is due to deficiency of N, K, S and Mo. Inhibition of cell division is due to deficiency of N, K, S and Mo, and delay of flowering is due to the deficiency of N, S and Mo.

Detailed explanation-4: -Where the plant has insufficient molybdenum the nitrates accumulate in the leaves and the plant cannot use them to make proteins. The result is that the plant becomes stunted, with symptoms similar to those of nitrogen deficiency.
