Ferritin extraction was done following the method of Lane and Skopp 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 not zinc or cadmium. Constitutive expression of soybean ferritin cDNA in transgenic wheat and rice results in increased iron levels in vegetative organs but not in seeds.

Certified standards Perkin Elmer were run with every determination Watson and Robert, ; Jones et al. Moreover, constantly high iron contents in leaves indicates that iron reached the mesophyll cells and was stored in ferritin protein and, when released, is most likely used by the leaf cells themselves and not for export Walter et al.

The cp5 sequence is identical to other legume ferritin sequences such as soybean Ragland et al. A practical sampling, preparation, analysis, and interpretation guide. Analytical instruments for soils and plant analysis. Relative expression of ferritin gene.

The sample was centrifuged for 3 h at 13 rpm Heraeus Biofuge Stratos rotor and the supernatant discarded. Posttranscriptional regulation of ferritin during nodule development in Soybean.

One hundred seeds of each of four common bean cultivars: The utilized cultivars are representative of the commercial classes widely produced and consumed in Mexico. The structure of a Phaseolus vulgaris cDNA encoding the iron storage protein ferritin. Seeds had the highest content starting at stage II 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.


Ferritin synthesis in animal cells is regulated at transductional level in the presence of iron Theil et al. Ferritin genes have been documented from numerous animals, plants, and microbes Theil, ; Harrison and Arosio, ; Proudhon et al.

This is similar to frijoo 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. Structure and differential expression of the four members of the Arabidopsis thaliana ferritin gene family.

Some authors reported a close correlation between ferritin messenger and ferritin protein content with varying iron levels Van der Mark et al.

Variable amounts of translatable ferritin mRNA in bean leaves with various iron contents. There were significant differences among cultivars. Differences in iron content among plant organs are due to the fact that much of the iron in leaves, for example, is associated with the ferrodoxins required for photosynthesis as part of the reverse tricarboxylic acid cycle Fromme et al. 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.

However, similarities in subunits cp1, cp2, cp3 sequences do not imply similar expression levels. Regulation of ferritin and transferrin receptor mRNAs. Harvest Plus Technical Monograph 1.

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

Ferritin gene transcription is regulated by iron in soybean cell cultures. Iron content and ferritin gene expression in common bean Phaseolus vulgaris L.


Sequence similarities between cp5 and common bean ferritin did not represent a similar expression pattern. Nutrition of macrominerals and trace elements. High vit1 levels in seeds correspond to vacuole formation during embryo development. Purification and partial characterization of ferritin from normal and iron loaded leaves of Phaseolus vulgaris. However no correlation was observed with iron content indicating an independent event between iron concentration and ferritin expression and protein content.

Localization of iron in Arabidopsis seed requires the vacuolar membrane transporter VIT1. AH had higher levels of ferritin gene expression than the other cultivars. In legumes, iron is located mostly in ferritin Ambe et al.

Iron transport and storage in microorganisms, plants and animals. Occurrence and expression of members of the ferritin gene family in cowpeas. Registration of ‘Flor de Junio Marcela’ common bean.

Higher values in all plant organs always corresponded to AH Table 1. A simple method frrijol purifying azkfrado. Accumulation of phytoferritin and starch granules in developing nodules of soybean roots infected with Heterodera glycines. Registration of “Pinto Villa” common bean. Assessment of relative expression.

Research focusing on the analysis of the iron demand by the plant is abundant. Soil testing and plant analysis. Similarly to our observations, Ragland and Theil reported that developmental changes in ferritin protein concentrations were not coordinated with ferritin mRNA. Structure, function, and evolution of ferritins. Structure of photosystem I.

An introduction to statistical methods and data analysis.
