Absorption and Function of Zinc in Plants Zinc is taken up predominantly as a divalent cation (Zn 2+), but at high pH it is probably absorbed as a monovalent cation (ZnOH +) .Zinc is either bound to organic acids during long distance transport in the xylem or may move as free divalent cations. 27, 939–950. J. Agr. Function of Copper. Plant Physiol. (Manu Solanki 2016) As zinc is a limiting factor for crop production, this study on zinc solubilization by bacteria has an immense role in zinc nutrition to plants. Rahimi A and Schropp A 1984 Carbonic anhydrase activity and extractable zinc as indicators of the zinc supply of plants. Your body’s first line of defense (known as the innate immune system) relies on a steady supply of zinc. Manganese (Mn) and zinc (Zn) play essential roles in plants. Zinc deficiency also increases membrane leakiness by inhibiting the activity of enzymes involved in the detoxification of membrane damaging oxygen radicles. Thus, zinc may play a role in controlling gene expression. Zinc is also involved in the synthesis of auxin, a plant hormone that helps plants determine whether to focus on growing tall or becoming bushy. J. Agric. 52, 229–232. Shrotri C K, Tewari M N and Rathore V S 1978 Morphological and ultrastructural abnormalities in zinc deficient maize chloroplasts Nutritional deficiencies. Zinc deficiency occurs when plant growth is limited because the plant cannot take up sufficient quantities of this essential micronutrient from its growing medium. Absorption and Function of Zinc in Plants Zinc is taken up predominantly as a divalent cation (Zn 2+), but at high pH it is probably absorbed as a monovalent cation (ZnOH +) . 179, 187–191. Powerful Micronutrient. The most common fertilizer sources of Zinc are Zinc chelates (contain approximately 14% zinc), Zinc Sulfate (25-36% zinc) and zinc oxide (70-80% Zinc), where Zinc Sulfate is the most commonly used source of zinc. Recent evidence suggests that zinc plays a key role in stabilizing RNA and DNA structure, in maintaining the activity of DNA synthesizing enzymes and controlling the activity of RNA degrading enzymes. It helps our blood clot, makes proteins and DNA, helps our wounds to heal, and supports the function of a healthy immune system. Zinc is essential for proper immune function. Takaki H and Kushizaki M 1970 Accumulation of free tryptophan and trytomine in zinc deficient maize seedling. 32, 433–442. Zinc is an essential plant micronutrient. Plant Mol. Adv. Zinc plays an important role in basic cellular functions in all the group of living organisms and is also play important role in human immune system. This means that zinc contained in grains and plants is not as well absorbed as zinc found in seafood and meat. Res. Sci. Forest Ecology and Management 37, 187–205. J. Bot. Reed H S 1940 Effects of zinc deficiency on phosphate metabolism of the tomato plant. Kitagishi K, Obata H and Kondo T 1987 Effect of zinc deficiency on 80S ribosome content of meristematic tissues of rice plant. J. Bot. J. Agr. Zinc is present in a wide variety of foods, but it is important to remember that phytates (the major storage form of phosphorous) can bind zinc and inhibit its absorption. Salami A U and Kenefick D C 1970 Stimulation of growth in zinc-deficient corn seedlings by the addition of tryptophan. Zinc, a nutrient found throughout your body, helps your immune system and metabolism function. © 2020 Springer Nature Switzerland AG. Miyazaki Univ. Why Apply Zinc to Rice? Soil conditions that can result in zinc deficiency include: Visual observation can be a quick diagnostic tool to identify zinc deficiencies. Hanas J S, Hazuda D J, Bogenhagen D F, Wu F Y H and Wu C W 1983 Xenopus transcription factor A requires zinc for binding to the 5S RNA gene. Although Zn is required in small amounts, high yields are impossible without it. In the following review we summarize the current knowledge of the physiology of zinc and illustrate areas in which our knowledge remains incomplete. Immune Function. Fridovich 11986 Biological effects of the peroxide radical. Your second line of defense (your adaptive immune system) also relies on zinc. Function of Zinc Zinc activates enzymes that are responsible for the synthesis of certain proteins. Hu H and Sparks D 1990 Zinc deficiency inhibits reproductive development in ’Stuart’ pecan. Do you want to receive updates and interesting articles every day? Leave your email and always receive new articles in our weekly newsletter. It is needed by plants in small amounts, but yet crucial to plant development. Pasteur 28, 21–68. Many of the physiological perturbations resulting from zinc deficiency are associated with the disruption of normal enzyme activity, thus zinc-deficiency induced inhibition of photosynthesis is coincident with a decrease in activity of key photosynthetic enzymes. 35, 172–179. As a component of proteins, zinc acts as a functional, structural, or regulatory cofactor of a large number of enzymes. Bot. 35, 721–727. Copper activates some enzymes in plants which are involved in lignin synthesis and it is essential in several enzyme systems. 27, 1010–1012. By subscribing to the newsletter you agree with Privacy Policy & Terms and Conditions. The essential micronutrient zinc occurs in plants either as a free ion, or as a complex with a variety of low molecular weight compounds. Defense-Related Functions of Zinc in Plants Zinc is a catalytic and structural protein cofactor in hundreds of enzymes (Hambidge et al., 2000) and has key structural functions in the protein domains that interact with other molecules. What Are the Benefits of Zinc? 5, 89–96. It plays an important role in a wide range of processes, such as growth hormone production and internode elongation. Zinc is also present in animal-based foods, and that’s because the animals have already digested plants that contain zinc. Biophys. Recommends the ideal fertilizer mixture/ blends, Comprehensive data on hundreds of crop varieties, Interprets test results for any extraction method. Click here to learn more. Eds. 245, 2656–2666. Nat. As a component of proteins, zinc acts as a functional, structural, or regulatory cofactor of a large number of enzymes. Zinc is one of the eight essential trace elements that plants need for normal growth and reproduction. Regular soil or plant testing is the best practice to determine if zinc application is required and to ensure that zinc does not accumulate in the soil to undesirable high levels. Form: Molybdenum is primarily taken up as MoO 4 2-(molybdate ion). Kitagishi K and Obata H 1986 Effects of zinc deficiency on the nitrogen metabolism of meristematic tissues of rice plants with reference to protein synthesis. Vodkin M H and Vodkin L O 1989 A conserved zinc finger domain in higher plants. Aust. King S W and Fife T H 1983 Effects of metal ion substitution on carboxypeptidase A catalized hydrolysis of O-trans-cinnamoyl-L-ß-phenyllactate. 33, 423–429. The essential micronutrient zinc occurs in plants either as a free ion, or as a complex with a variety of low molecular weight compounds. If a plant is deficient in zinc it will not be able to mature as fast as other non-deficient plants. Also you can download a pdf file with a list of crops here. Zinc (Zn) is taken up by plants as the divalent Zn²⁺ cation. Your success is our goal, you could receive special offers and start saving up to 60% on your fertilization costs!
