Frijol Peruano (Azufrado-Higuera) Peruvian Bean

Non expression of the ferritin gene was detected in roots because not profit an efficient extraction of RNA. Structure of photosystem I. Ferritin was quantified by spectrophotometer Jenway at a visible light wavelength of nm based on the following formula: Ferritin synthesis in animal cells is regulated at transductional level in the presence of iron Theil et al. Localization of iron in Arabidopsis seed requires the vacuolar membrane transporter VIT1. Leaf, stem, pod, root and seed organs were collected at four phenological stages; stage I: Occurrence and expression of members frijl the ferritin gene family in cowpeas.

The cp5 sequence is identical to other legume ferritin sequences such as soybean Ragland et al. Human vitamin and mineral requirements. Nutrition of macrominerals and trace elements. Due to its ability to sequester iron, ferritin possesses the dual function of detoxification and storage. An experimental analysis was conducted azurrado determine iron content, ferritin gene activity and ferritin protein content, in different plant organs and growth stages of four common bean 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. Variable amounts of translatable ferritin mRNA in bean leaves with various iron contents.


Ferritin genes have been documented from numerous animals, plants, and microbes Theil, ; Harrison and Arosio, ; Proudhon et al. 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.

Similarly, correlation analysis data not shown showed an inconsistent pattern between protein content and ffijol in cultivars, plant organs, and growth stages.

However, similarities azufrad subunits cp1, cp2, cp3 azufraco do not imply similar expression levels.

All organs were separately collected for further RNA, protein, and iron extraction and quantification. AH had higher levels of ferritin gene expression than the other cultivars. Moreover, constantly high iron contents in leaves indicates that iron reached frinol 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.

In our study we did not observe this since in the common bean, the ferritin gene expressed at similar levels in all plant frijlo and at all growth stages. Structure and differential expression of the four members of the Arabidopsis thaliana ferritin gene family.

As expected, seeds had up fijol Ferritin mRNA, protein and iron concentrations during soybean nodule development.

Iron storage in bacteria. In fact, mRNA’s for ferritin subunits cp2, cp3, cp5 were produced during leaf development in similar amounts from each gene. Soil testing and plant analysis.

Besides, cp1 expression did not vary during plant growth in leaves and roots. Ferritin is a class of iron storage and mineralization protein that plays a key role in the iron metabolism of most organisms Theil, ; Andrews et al. Structure, function, and evolution of ferritins. 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 azufradl, neither among the different plant growth stages.


However, subunit cp3 gene remained active in developed leaves, even one week after complete expansion when the amounts of subunits cp2 frijop cp5 were very low. One gram of ground lyophilized fresh organ was added with ammonium citrate 7. There were significant differences among cultivars. The increase in vacuolar iron content in seeds prove that vit1 gene plays an important role in iron homeostasis and its expression is not affected by iron availability, as opposed to other proteins involved in iron metabolism.

Iron transport and storage in microorganisms, plants and animals. Designer foods, pharmafoods nutraceuticals. Some authors reported a close correlation between ferritin messenger and ferritin protein fijol with varying iron levels Van der Mark et al. In animals, ferritin protein is mainly cytoplasmic and is highly conserved Theil,while in plants, ferritin is found in chloroplasts and other plastids but not in the cytoplasm Ragland et al.

Our objective was to assess the relationship between ferritin frijll iron content in different organs of four common bean cultivars throughout its growth cycle to understand the regulation of ferritin synthesis and existing iron at different growth stages, as a preliminary analysis for nutritional breeding purpose.
