- Common bean (Phaseolus vulgaris L.) has two major origins for domestication, Andean and Mesoamerican, which contributed to high genetic diversity reflected by different pod and seed characteristics and growth types. (usda.gov)
Abstract1
Protein2
- Another protein, the homologue of the transcriptional iron regulator RirA in Rhizobium legummosarum was identified and characterised in S mehloti as the new general regulator of iron responsive genes. (dcu.ie)
- Hemoglobin is an iron-containing protein in red blood cells that transports oxygen to tissues throughout the body. (cshlpress.com)
Pancreas2
- it also allows assessment of iron load in the pancreas, heart, and spleen. (medscape.com)
- Whereas most people are familiar with a lack of iron, or anaemia, iron overload is much less well known, even though it can lead to dangerously high levels and problems, particularly in the liver, pancreas, heart and joints. (dailymail.co.uk)
Abnormal2
- Other genetic conditions may contribute to anemia by causing abnormal bleeding. (healthline.com)
- the other hypothesizes that the abnormal handling of iron by the liver leads to liver injury and failure. (medscape.com)
Mechanisms3
- Findings indicate that ADHD and narcolepsy are genetically related, and there are possible common underlying biological mechanisms for this relationship. (nature.com)
- To ensure iron supply but to avoid iron toxicity, all organisms evolved sophisticated mechanisms to balance acquisition, storage, and consumption of iron. (frontiersin.org)
- Thus, understanding the interplay among environmental and genetic factors, in relation to the respective involved mechanisms, is the cornerstone of targeted interventions, both at individual and community level. (aiche.org)
Mutation3
- The G277S transferrin mutation is found to influence iron metabo lism and predispose menstruating white women to iron deficiency anaemia. (europa.eu)
- When an individual is found to be a carrier for a genetic condition, his or her relatives are at risk of carrying the same mutation. (acog.org)
- [ 4 ] H63D mutation does not result in constitutional iron overload unless it occurs as a compound heterozygote with C282Y (C282Y/H63D). (medscape.com)
Liver biopsy2
- The condition may be confirmed with a liver biopsy or genetic testing. (medlineplus.gov)
- If a blood test shows high Transferrin or Serum Iron levels, then a Liver function and Liver biopsy are used to test Liver damage and Iron levels in the liver. (wikibooks.org)
World's1
- Chickpea (Cicer arietinum L.) is the world's second most important pulse crop after common bean. (org.in)
Genotypes2
- Therefore, the aims of this study were to sequence the -Phs and FRO1 genes, to assess SNP frequencies in coding and non-coding regions of both genes, and to assess the possible use of these polymorphisms for investigating the genetic diversity of 31 cultivated genotypes of common bean and one of P. lunatus.

Diversity1
Genes2
- Additionally, the investigation of nucleotide sequences that code for important proteins, such as phaseolin and iron-reductase, encoded respectively by the Phs and FRO1 genes, should allow new and informative markers to be generated, helping us to gain a better understanding of intraspecific variation in P. vulgaris. (usp.br)
- All of the virulence-associated genes are transcriptionally upregulated during iron starvation and encode functions that are important for survival during iron starvation, which emphasizes the crucial role of adaptation to iron starvation in virulence. (frontiersin.org)
Builds up in the body1
- Iron builds up in the body. (medlineplus.gov)
Excess iron from the body2
- The goal of treatment is to remove excess iron from the body and treat any organ damage. (medlineplus.gov)
- The mainstay of treatment is venesection - blood-letting - to drain excess iron from the body. (dailymail.co.uk)
Levels7
- Most patients need to have one pint a fortnight removed until their iron levels have returned to normal - after which they have it once every three months or so. (dailymail.co.uk)
- The most common reasons are genetic male pattern baldness, stress, poor diet , or low iron levels. (transforminglives.co.uk)
- Beets are not only incredibly high in iron, but they also contain high levels of vitamin C. Beets have an earthy flavor that many people dislike, which makes them somewhat of a challenge to eat, but there are several delicious ways to enjoy beets. (progressivehealth.com)
- [5] This is as simple as donating blood at the Red Cross and the blood can be used as normal, initially phlebotomies may be needed every two weeks until Iron levels are reduced to normal, then every 12 weeks to maintain levels. (wikibooks.org)
- Common bean is an important legume crop with two major genepools that has been the focus of genetic improvement for seed micronutrient levels. (edu.au)
- Our aim was to evaluate associations between common HFE and Transferrin polymorphisms and toenail cadmium levels among older men. (cdc.gov)
- Scarring from macrophages, which contain high levels of stainable iron, may be present. (medscape.com)
Populations2
- NEW YORK - A new study has shed light on the genetic relationship between Finns and Estonians, Northern European populations that, while separated by the Gulf of Finland, have languages that are closely related, suggesting recent common ancestry. (genomeweb.com)
- According to lead author Toomas Kivisild, a population geneticist at KU Leuven, the study is part of "broader and longer-term research into the genetic origins of Finno-Ugric populations" undertaken by the Institute of Genomics in Tartu. (genomeweb.com)
Bean2
- The population had 110 lines and was derived from a high-seed iron and zinc climbing bean genotype (G14519) crossed with a low-mineral Carioca-type, prostrate bush bean genotype (G4825). (edu.au)
- The genetic map for QTL analysis was created from SSR and RAPD markers covering all 11 chromosomes of the common bean genome. (edu.au)
Nutrient2
- Iron is an essential nutrient for most bacteria. (dcu.ie)
- Iron is an essential nutrient for all eukaryotes and nearly all prokaryotes ( Kaplan and Kaplan, 2009 ). (frontiersin.org)
Concentrations2
- The objective of this study was to evaluate the inheritance of seed iron and zinc concentrations and contents in an intra-genepool Mesoamerican × Mesoamerican recombinant inbred line population grown over three sites in Colombia and to identify quantitative trait loci (QTL) for each mineral. (edu.au)
- The discovery of an important new locus for seed iron and zinc concentrations may facilitate crop improvement and biofortification using the high-mineral genotype especially within the Mesoamerican genepool. (edu.au)
