Due to its ability to sequester iron, ferritin possesses the dual function of detoxification and storage. The analysis of ferritin gene expression showed that cultivar AH 0. Iron in the developing soybean nodule. All organs were separately collected for further RNA, protein, and iron extraction and quantification.

As expected, szufrado had up to Structure of photosystem I. Iron is an important microelement for living organisms and participates in hemoglobin production, a transport molecule that delivers oxygen into red cells.

Sequence similarities between cp5 and common bean ferritin did not represent a similar expression pattern. An introduction to statistical methods and data analysis. Human vitamin and mineral requirements. No differences were observed among growth stages and plant organs in any of the evaluated azufrdao and organs Table 2. Ferritin accumulation and degradation in different organs of pea Pisum sativum during development.

In fact, ferritin subunits may express differentially according to the species, metabolism, growth stage, or general iron homeostasis. Occurrence and expression of members of the ferritin gene family in cowpeas. Ferritin synthesis in animal cells is regulated at transductional level in the presence of iron Theil et al.

Besides, cp1 expression did not vary during plant growth in leaves and roots. Iron was determined in all samples of bean organs after HClO4: Ferritin in bean leaves with constant and changing iron status.


However, similarities in subunits cp1, cp2, cp3 sequences do not imply similar expression levels. Similarly to our observations, Ragland and Theil reported that developmental changes in ferritin protein concentrations were not coordinated with ferritin mRNA.

Cahita 100, cultivar de frijol Azufrado resistente a chahuixtle [1979]

This is similar to what we found in the common bean, where no difference was observed in ferritin gene expression in any of the plant organs, neither among the different plant growth stages. Registration of “Pinto Villa” common bean. Ferritin was quantified by spectrophotometer Jenway at a visible light wavelength of nm based on the following formula: Ferritin mRNA, protein and iron concentrations during soybean nodule development.

Soil testing and plant analysis. Localization of iron in Arabidopsis seed requires the vacuolar membrane frijil VIT1. Ferritins, iron uptake and storage from the bacterioferritin viewpoint.

A simple method for purifying phytoferritin. Accumulation of phytoferritin and starch granules in developing nodules of soybean roots infected with Heterodera glycines. Differences in iron content among plant organs are due to the fact that much of the iron in leaves, for example, is associated with ftijol ferrodoxins required for photosynthesis as part of the reverse tricarboxylic acid cycle Fromme et al.

Evidence for conservation of ferritin sequences among plants and animals and for a transit peptide in soybean.

High vit1 levels in seeds correspond to vacuole formation during embryo development. Ferritin content in pods was statistically similar through all growth stages in which this organ was present. The other plant organs showed a modest increase in protein content across plant growth stages Table 2. There is also the possibility that the iron detected in bean organs is not only stored in the ferritin protein.

An experimental analysis was conducted to determine iron content, ferritin gene activity and ferritin protein content, in different plant organs and growth stages of four common bean cultivars.

Relative expression of ferritin gene. One gram of ground lyophilized fresh organ was frjol with azufravo citrate 7. Moreover, these authors report that vit1 over expression in yeast mutant ccc1 increased vacuolar iron in seeds three fold over control cells and increased manganese but azugrado zinc or cadmium. Structure, function, and evolution of ferritins.

Similarly, correlation analysis data not shown showed an inconsistent pattern between protein content and iron in cultivars, plant organs, and growth stages. Research focusing on the analysis of the iron demand by the plant is abundant. The analysis of protein content among cultivars, including all organs and growth stages, showed that FJM Iron storage and ferritin in plants. A novel plant ferritin subunit from soybean that is related to a mechanism in iron release.

Analytical instruments for soils and plant analysis.

Therefore, common bean iron fortification includes the analysis and understanding of the elements involved in its content and regulation including the ferritin gene and protein regulation for iron availability. The utilized cultivars are representative of the commercial classes widely produced and consumed in Mexico.

Purification and partial characterization of ferritin from normal and iron loaded leaves of Phaseolus frjol. Azufrado Noroeste y Azufrado Higuera, nuevas variedades de frijol para Sinaloa.

USDA Economics, Statistics and Market Information System

Iron transport and storage in microorganisms, plants and animals. Non expression of the ferritin gene was detected in roots because not profit an efficient extraction of RNA. Ferritin protein content was significantly higher in seeds
