MicroRNAs are recognized as important post-transcriptional regulators in plants. Information about the roles of miRNAs common bean (Phaseolus vulgaris L.), an agronomically legume, is yet scant. The objective this work was to functionally characterize conserved miRNA: miR398b and its target Cu/Zn Superoxide Dismutase 1 (CSD1) bean. We experimentally validated a novel miR398 target: stress up-regulated Nodulin 19 (Nod19). Expression analysis genes -CSD1 Nod19- roots, nodules leaves, indicated...
Metal toxicity is a major stress affecting crop production. This includes metals that are essential for plants (copper, iron, zinc, manganese), and non-essential (cadmium, aluminum, cobalt, mercury). A primary common effect of high concentrations metal such as copper, cadmium, or mercury root growth inhibition. triggers the accumulation reactive oxygen species leading to damage lipids, proteins, DNA. The response involves several biological processes require fine precise regulation at...
La simbiosis entre leguminosas y bacterias fijadoras de nitrógeno, comúnmente nom-brados rizobios, es fundamental para proveer nitrógeno asimilable a la cadena alimenticia. Du-rante dos décadas se han estudiado intensivamente los mecanismos genéticos que controlan el es-tablecimiento funcionamiento esta simbiosis, cual afectada por disponibilidad fos-fato. Estudios en diferentes indican deficiencia fosfato reduce significativa-mente fijación simbiótica nitrógeno. A pesar estos avances,...
Aluminum (Al) toxicity is widespread in acidic soils where the common bean (Phaseolus vulgaris), most important legume for human consumption, produced and it a limiting factor crop production symbiotic nitrogen fixation. We characterized nodule responses of plants inoculated with Rhizobioum tropici CIAT899 root nitrate-fertilized exposed to excess Al low pH, long or short periods. A 43-50% reduction nitrogenase activity indicates that (Alt) highly affected fixation bean. Bean roots nodules...
Arbuscular mycorrhizal symbiosis is an association that provides nutritional benefits to plants. Importantly, it induces a physiological state allowing plants respond subsequent pathogen attack in more rapid and intense manner. Consequently, mycorrhiza-colonized become less susceptible root shoot pathogens. This study aimed identify some of the molecular players potential mechanisms related onset defense priming by mycorrhiza colonization, as well miRNAs may act regulators genes. The...
El descubrimiento de los microRNAs (miRNAs) ha revolucionado la biomedicina moderna. Estas pequeñas moléculas RNA, 18-24 nucleótidos, son reguladores clave expresión génica, actuando como "interruptores" que controlan activación o silenciamiento genes en momentos críticos. Su impacto comprensión procesos celulares y enfermedades sido reconocido con el Premio Nobel Medicina. Los miRNAs se han convertido herramientas prometedoras diagnóstico tratamiento complejas Alzheimer, diabetes mellitus...
La diabetes mellitus (DM) es una epidemia creciente que plantea gran amenaza para la salud mundial. Se estima actualmente 527 millones de personas alrededor del mundo tienen DM y en los próximos 25 años prevalencia mundial aumentará un 46%. afección grave crónica ocurre cuando se elevan niveles glucosa sangre, debido a el organismo no puede producir suficiente hormona insulina o utilizar eficazmente.
