WebStudies with sterile root materials showed that the optimum pH values of phosphatase activity in three varieties of each of corn (Zea mays L.) and soybean (Glycine max. L.) were 4 and 5, respectively. The activity on either side of the optimum pH fell sharply, and there was no activity at pH 9. Thus, these roots contain acid but no alkaline phosphatase activity. … Web33.5.3 Acid Phosphatase. Phosphatases or phosphomonoesterases are the hydrolytic enzymes that cleave the ester bond between the phosphate group and the organic residue of the organic phosphates. Based on the optimum pH for the activity, phosphatases are of two kinds: acid and alkaline.

WebRoot phosphatase activity is used as a 'do it yourself' strategy of soil P acquisition, and was found to be inversely correlated with mycorrhizal colonization, which suggests a trade-off in plant P acquisition strategies. Compared with soil and foliar nutrient status, root traits mattered most for the large inter-specific changes in RPA.

The activity of acid phosphatase secreted by the roots increased under P-deficient conditions in all the species examined. That of lupin increased most remarkably. The properties of the enzyme secreted by the roots of lupin was investigated. Many isozymes existed in the roots and … colored pencil crafts for adults
