AnemiaIron deficiency caused by disease is a pervasive health problem worldwide. To solve this problem, ChinaScienceHome has made a major breakthrough: they are inCornThe discovery of an iron transport molecular switch in the grain is expected to help people in theDaily dietMedium effective ingestionIron element。December 8th,Chinese AgricultureScienceyard cropsScienceInstitute and HenanAgricultureThe university jointly released the results of this study, revealing how the gene ZMNAC78 and the metal transporter work together to form a molecular switch and controlIron elementEnterCornMechanism of the grain. ScienceHome using this gene successfully raisedCornIron content in the kernels, per kilogramCornUp to 705 mg than usualCornThe average iron content has increased by more than 2 times. At the same time, they also used this discovery to develop iron-rich onesCornThe new varieties provide new genetic resources for solving the problem of iron deficiency.
CornAs one of the most important crops in the world, it is widely used in the manufacture of many food and industrial products. However,CornThe iron content of the grains has not always been high, which is very importantIron elementThis is a big problem for people who are not getting enough intake. According to the data of the Fourth National Nutrition Survey, residents of ChinaAnemiaThe prevalence is 201%, half of which is:Iron deficiency anemia。Although iron status can be improved by taking iron supplements, for example, this method is costly. Therefore,ScienceFamilies are committed to improvingCorniron content so that people are inDaily dietBetter ingestionIron elementto improve iron status at low cost.
CornThe discovery of molecular switches for grain iron transport is of great significance. First, the findings provide a solution to the problem of iron deficiency on a global scaleNew ideasand new materials. According to statistics, about one-third of the world's population is affected by iron deficiencyAnemiaHaunt. There have been beforeScienceHome inRiceThe field has made great progress, but due toCornThe structural characteristics of the grain are different, and nutrients such as iron need to be transported through the basal endosperm and cells to enter the grain. in the improvementCornThe iron content has been an open question. Now,ScienceThe family found control by analyzing the mechanism of action of the gene ZMNAC78 and the metal transporterIron elementEnterCornThe key to the grain, which provides a solution to the nutrient absorption problem of other cereal-like crops with delivery cellsNew ideas
In addition,CornThe discovery of the molecular switch for grain iron transport also bringsCornBreeding of new varieties. ScienceThe home used this discovery to develop an iron-rich oneCornNew varieties and successfully applied to actual production. This breakthrough contributes to a radical improvementCorniron content to provide people with more nutritious food choices. For those who use toCornforStaple foodof developing countries, this progress is particularly important to help improve people's iron status, which in turn improves overall health.
Iron deficiency is a major global health challenge. Caused by iron deficiencyAnemiaIt has serious implications for human health, especially for pregnant women and children. Although iron supplementation is currently available to improve iron status, it is costly and not a long-term solution. Therefore,ScienceFamilies are committed to increasing the iron content in crops to solveIron elementThe problem of insufficient intake.
CornThe discovery of molecular switches for grain iron transport provides a solution to the problem of iron deficiencyNew ideas。By controlling the action of the gene zmnac78 and metal transporters,ScienceThe home has succeeded in increasingCorniron content in the grains, and bred to be iron-richCornNew varieties. This finding can also be used as a reference for the nutrient absorption of other similar cereal crops, and is expected to provide new ideas and methods for improving iron content in other food crops.
In addition, through researchCornGrain iron transports molecules in the process of switchingScienceSome key genes and molecular mechanisms have also been discovered. These findings can be used not only for improvementCornvariety, which can also provide clues and guidance for solving other related problems. For example, certain crops that have the characteristics of transmitting cells, such as:Wheatand so on, but also faced with the problem of nutrient absorption and transport, and these problems are inCornSome breakthroughs have been made in the research. Therefore,CornThe discovery of molecular switches for grain iron transport is of great significance for the entire field of plant nutrition, which is helpful to promote the research and application in related fields.
By discoveryCornMolecular switch for grain iron transport, ChinaScienceChina has made an important breakthrough in solving the global iron shortage problem. This discovery is not only for the solutionIron elementThe problem of insufficient intake provides new ways and ideas, and also provides a reference for the improvement and nutrient absorption of other crops. ScienceThe family used this discovery to develop an iron-rich oneCornThe new varieties provide new genetic resources for improving iron nutrition. Iron deficiency is a major global health challenge, and this breakthrough is expected to alleviate globallyAnemiaproblems, to improve people's health. We look forward to the futureScienceThe continuous efforts and breakthroughs in this field will make greater contributions to solving global nutrition problems.
