This article explains everything you need to know about zinc, its functions, benefits, the risk of deficiency and potential side effects. Zinc Deficiency (Hudda disease - Pakistan, Khaira disease - India). However, since a decrease in the serum concentration is only detectable after long-term or severe depletion, serum zinc is not a reliable biomarker for zinc status. Control Fed. Bronzing symptoms of zinc deficiency on rice leaf. N ENE (1) was the first to show that a foliar application of zinc sulfate corrects a disorder of the rice plant long known as Khaira disease in North-Central India. Areas with zinc deficient soils are often regions with widespread zinc deficiency in humans. 53–57 (1972). Background: Zinc (Zn) deficiency is one of the most widespread soil constraints affecting rice productivity, but the molecular mechanisms underlying the regulation of Zn deficiency response is still limited. Zinc (Zn) is an indispensable element for rice growth. Agron. Studies on two varieties differing in susceptibility to zinc deficiency. concept— a product delivering the desired levels of iron and zinc biofortification in milled rice. Several studies have investigated how rice plants respond to Zn deficiency and examined the differences between Zn-efficient (ZE) and Zn-inefficient (ZI) genotypes. Y. L. N ENE (1) was the first to show that a foliar application of zinc sulfate corrects a disorder of the rice plant long known as Khaira disease in North-Central India. “[So we believe that rice containing higher zinc levels] should be considered for populations that consume mostly parboiled or highly polished rice, [and also that] despite some known nutritional benefits of parboiled rice, for populations with high zinc deficiency it is prudent to promote the consumption of non-parboiled over parboiled rice.” and Plant Nutrition (Japan) 17, 83–87 (1971). Zn deficiency can be caused by many factors, e.g. Am. Thorne, W., Zinc deficiency and its control. Symptoms When the zinc concentration was decreased to a level of less than 100 ppm, disorders of the nitrogen metabolism appeared. Soils particularly prone to zinc deficiency include: • Neutral and calcareous soils containing large quantities of bicarbonate. Zinc (Zn) deficiency is one of the leading nutrient disorders in rice (Oryza sativa). H idden hunger, or micronutrient deficiency, is a leading global problem. Proc. Soc. 24, 301–307 (1967). Soil Manure, Japan 40, 415–519 (1969) (In Japanese). International Rice Research Institute. Caroll, M. D. and Loneragan, J. F., Response of plant species to concentrations of zinc in solution I. Because zinc plays such an important role in your body, the symptoms of a deficiency can show up in a hundred ways. Those who can afford meat do not need to worry, meat has the necessary zinc required. Zn is only slightly mobile in the plant and quite immobile in soil. and Plant Nutrition 15, 75–80 (1969). (3)College of Resources and Environmental Sciences, Nanjing Agricultural University, Nanjing, 210095, China. Subscription will auto renew annually. Iron deficiency anemia (IDA) can affect productivity and cause serious health Paddy soil conditions are usually not favorable for the availability of zinc and hence zinc deficiency has been reported countrywide in rice soils (Bhatti and Rashid, 1985). ), The International Rice Research Institute, Los Baños, Philippines) pp. It can also be found in plant sources like tofu, hemp seeds, lentils, shiitake mushrooms, tahini, pumpkin seeds, wild rice, cashew, soybeans, and chia seeds. Dark brown to reddish spots appear on the slightly chlorotic young leaf. Sc.) Under severe Zn deficiency, tillering decreases or may even stop. Navrot, J., and Ravikovitch, S., Zinc availability in calcareous soils: III. Incidence of the deficiency appears more closely related to zinc availability than to total zinc content of the soil, and spontaneous recoveries of affected crops are common. 26, 144–147 (1962). Its occurrence has increased with the introduction of modern varieties, crop intensification, and increased Zn removal. Soil Sci. Zinc deficiency is a particular problem in rice because of the chemistry of submerged rice paddy soils, which results in Zn being extremely insoluble in many rice soils and therefore hard for the plants to … Stunted, uneven growth. 89, 296–302 (1960). It is by Donald Groth at Louisiana State University AgCenter. Pratt, P. F., Carbonate and bicarbonate In Diagnotic Criteria for Plants and Soils (H. D. Chapman Ed., Univ. It means many people who depend on rice as a staple food are effectively being starved of essential micronutrients such as iron, zinc and pro-vitamin A.. Nutritionists call it "hidden hunger." DiLallo, R. and Albertson, O. E., Volatile acids by direct titration. Soc. Rice is sensitive to Zn deficiency; it is the most widespread micronutrient disorder in rice. Solution culture studies with the variety IR8 showed that with a bicarbonate concentration of only 15 mM, transport of zinc to the shoots was reduced by more than 70 per cent. Tanaka, A., Shimono, K. and Ishizuka, Y., (Zinc deficiency as the cause of the “Akagare” in the rice plants). Aerobic rice is currently bred by crossing lowland with upland rice genotypes, for growth in an aerobic cultivation system, which is saving water and producing high yields. Soc.

Here, we report a detailed study of the impact of Zn deficiency on crown root development of rice genotypes, differing in their tolerance to this stress. - 104.171.4.183. Reasons Results of the present study indicate that transient peaks in the concentration of bicarbonate and possibly of organic acids in the soil solution following soil submergence may induce temporary zinc deficiencies. H. D. Chapman, Univ. These consequences necessitate the design and evaluation of effective programs and policies for reducing micronutrient deficiencies. In Pakistan, the most recent national nutrition survey indicated that over 40% of women are zinc deficient. Y.) Zinc deficiency in rice. As depicted in figure 1, the morphological changes i.e., length of radical and plumule was shown in response to Zn NP treatment when subjected to 0 … Zinc (Zn) is an essential micronutrient for living organisms, and understanding the molecular mechanisms of Zn deficiency may help to develop strategies to mitigate this problem. Zinc-deficient soils constrain rice production and cause Zn-malnutrition. pp. Part of Springer Nature. Ind. Enhancing this Fe 3+ reduction via mutational‐reconstructed ferric chelate reductase improves yields and confers improved tolerance to iron deficiency when rice plants are grown in calcareous soil (Ishimaru et al. Proc. 10, 35–36, 39–40 (1970). pp. 119–146 (1967). This article explains everything you need to know about zinc, its functions, benefits, the risk of deficiency and potential side effects. Its occurrence has increased with the introduction of modern varieties, crop intensification and increased zinc removal. Soil factors associated with the deficiency, Plant and Soil Fe and Zn deficiencies are widespread and affect millions of Filipinos across ages and social strata with health and economic consequences. Using a chelated Zn source allows any of the Zn that does not contact rice leaves to be mobile in the soil and move downward towards the rice roots where it can also be actively taken up by the plant. Now the fifth leading factor in widespread disease worldwide, zinc deficiency is responsible for a rise in mortality rates in undeveloped nations due to connections to childhood diarrhea and pneumonia. A., Effect of the pH and salt concentration on Zn sorption by soils. Hodgson, J. F., Chemistry of the micronutrient elements in soils. The research initiated within the JIRCAS abiotic stress project led to the identification of several QTL associated with tolerance to Zn deficiency. Soil Sci. 19, 446–448 (1955).

Zinc fortified rice for India and Bangladesh (2013) A., Ammonium bicarbonate in plant nutrition. Zn deficiency can be caused by many factors, e.g. Zinc (Zn) deficiency was first identified as a field problem in rice in 1966 ().It is now widely recognized as one of the most widespread soil constraints in rice production, with as much as 50% of all lowland rice soils prone to Zn deficiency (Sillanpaa, 1990, White and Zasoski, 1999).In a survey of 14 sites in the Philippines, Van Breemen et al. Zinc (Zn) deficiency was first identified as a field problem in rice in 1966 ().It is now widely recognized as one of the most widespread soil constraints in rice production, with as much as 50% of all lowland rice soils prone to Zn deficiency (Sillanpaa, 1990, White and Zasoski, 1999).In a survey of 14 sites in the Philippines, Van Breemen et al. Zinc deficiency is the most widespread micronutrient disorder in rice. 2007a). Zinc (Zn) deficiency is the most prevalent micronutrient disorder in rice and leads to delayed development and decreased yield. Zn NP induced antioxidant changes of germinating rice seeds Zinc availibility decreases after flooding. Many studies have identified Zn-efficient rice genotypes, but causal mechanisms for Zn deficiency tolerance remain poorly understood.

However at pH 4.5 the same concentrations of acetic acid reduced uptake by more than 90 per cent. Many studies have identified Zn-efficient rice genotypes, but causal mechanisms for … But most cannot in Bangladesh. The researchers were aiming to increase that to at least 13 ppm to address iron … Zinc is an immobile nutrient in the soil and for early season or post-flood applications the rice typically has not fully canopied and much fo the soil surface remains exposed. Causes of Zinc Deficiency . Agr. Common symptoms include increased rates of diarrhea. Some plants like grains and beans contain phytate or phytic acid which binds to zinc and prevents its absorption. Zinc (Zn) deficiency is one of the most widespread soil constraints affecting rice productivity, but the molecular mechanisms underlying the regulation of Zn deficiency response is still limited. No. Studies have suggested a simple way to overcome zinc deficiency in humans is by applications of zinc to crops like rice. Zinc deficiency is more common among older people who live in institutions and people who are homebound. Zinc (Zn) deficiency is the most widespread micronutrient disorder in rice (Oryza sativa), but efforts to develop cultivars with improved tolerance have been hampered by insufficient understanding of genetic factors contributing to tolerance.

Rice grains usually contain just 2-5 parts per million (ppm) of iron. Duffner, A. ; Hoffland, E.; Stomph, T.J.; Boonstra, A.; Bindraban, P.S. Since much of the Philippines is derived from lime-stones and coral reefs, zinc deficiency of rice ought to occur in the Philippines. “[So we believe that rice containing higher zinc levels] should be considered for populations that consume mostly parboiled or highly polished rice, [and also that] despite some known nutritional benefits of parboiled rice, for populations with high zinc deficiency it is prudent to promote the consumption of non-parboiled over parboiled rice.” International Rice Research Institute. - Excessive liming. Sta., No. (In Japanese). Developing tissues such as meristems and reproductive organs require high zinc, but the molecular mechanisms of how zinc taken up by the roots is preferentially delivered to these tissues with low transpiration are unknown. Under neutral to alkaline conditions, acetic acid at 10 me/l produced only slight reductions in zinc uptake and transport to the shoots. Plant Soil 42, 537–550 (1975). Zinc Deficiency (Hudda disease - Pakistan, Khaira disease - India). Australian J. Agr. S. M. Impa, Sarah E.

Rice is one of the most important staple crops worldwide and a growing world population will lead to an increasing demand for food in the upcoming years. Zn deficiency resulted in a marked decrease in shoot dry matter production of most genotypes after 28 days of growth. Zinc deficiency scenario . Despite these differences, the two varieties appeared equally susceptible to zinc deficiency during the first four weeks of growth under field conditions. Zinc (Zn) deficiency in rice has been widely reported in many rice-growing regions of the world. - Precipitation of ZnS in anaerobic conditions. Queensland J. Agr. Zinc deficiency is the most widespread micronutrient disorder in rice. Zn deficiency results in brown blotches and streaks 2 to 3 weeks after transplanting, as well as stunting, reduced tillering, and low productivity of rice plants. Zinc deficiency remarkably depressed the zinc concentrations in the meristematic tissues of rice plants. In Lectures on the Inorganic Nutrition of Plants. Zinc Deficiency Do S.
