The RNA subunit of telomerase is an essential component whose primary sequence and length are poorly conserved among eukaryotic organisms. The phytopathogen Ustilago maydis is a dimorphic fungus of the order Ustilaginales. We analyzed several species of Ustilaginales to computationally identify the TElomere RNA (TER) gene ter1. To confirm the ident...

Antecedentes y Objetivos: Las coníferas, como los pinos, establecen en sus raíces simbiosis obligadas con hongos ectomicorrízicos y con determinados grupos de bacterias. México posee una alta diversidad de especies del género Pinus, que en este país está representado por 72 taxa. Sin embargo, actualmente son escasas las investigaciones relacionadas...

Se evaluó el desarrollo y producción de la col (Brassica oleracea var. Royal vantage) en invernadero, bajo diferentes presiones osmóticas de la solución nutritiva Steiner y biofertlizada con consorcios bacterianos. Se estableció un diseño factorial 4 × 3, donde los factores fueron cuatro niveles de presión osmótica (0.18, 0.36, 0.54 atm y un testig...

em>Burkholderia es un género ambivalente debido a que algunas de sus especies establecen relaciones simbiótico-mutualistas con las plantas, y simbiótico-patogénicas con plantas, animales y humanos. Desde que la bacteria fitopatógena B. cepacia fue reportada como oportunista nosocomial, asociada a la fibrosis quística, surgió la preocupación de posi...

The diseases found in Pinus patula, a species present in the forest area of Puebla, Mexico cause foliage loss and damage to trees and we consider that fungi could be involved. The objective of the current investigation was to study the nutrients of the soil and the fungi associated with the lesions on the needles of Pinus patula in Tetela de Ocampo...

Antecedentes: Pese a su amplia distribución y ubicuidad en diferentes ambientes, Cenococcum geophilum ha sido poco estudiado en México, en particular su asociación con especies en peligro de extinción, como es el caso de Pinus maximartinezii. Objetivo: Caracterizar morfológica y anatómicamente a Cenococcum geophilum asociado en condiciones natural...

Development of highly sensitive molecular sensors is of immense current interest for biomedical diagnosis. Although the possibility of single molecule detection through plasmonic sensors based on surface enhanced Raman scattering (SERS) has been demonstrated, the practical application of such devices is hindered due their complex fabrication strate...

El trabajo se realizó con el objetivo de evaluar el efecto de dos biofertilizantes en la producción de maíz, solos y combinados con dos fórmulas de fertilización química. El experimento se realizó bajo un diseño experimental de bloques al azar, con nueve tratamientos y cuatro repeticiones, conformando un total de 36 unidades experimentales. Los bio...

Introduction: Ectomycorrhiza and mycorrhiza helper bacteria are essential to the nutritional recycling of forest ecosystems. Objective: Growth, photosynthetic rate, chlorophylls, carotenes, root colonization and N, P and K contents were evaluated in Pinus montezumae plants inoculated with the edible ectomycorrhizal fungus Hebeloma mesophaeum (Hm),...

Zea mays L. ssp. mexicana (teosinte) is a naturally occurring grass related to maize. The two plants have developed foliar fungal diseases that can be controlled with beneficial bacterial antagonists. While the beneficial effects on stem and root development of the application of bacteria of the genus Azospirillum is widely known, the effects of th...

Cocoa plant (Theobroma cacao L.) is native from South America and it represents one of the most significant "bio-cultural" resources of Mesoamerica, since it is a region where it was domesticated and had a relevance as ritual drink and as currency in many pre-hispanic cultures until the arrival of the Spaniards who spread its use worldwide, and bec...

The chitinase enzyme was identified in isolated bacteria of maize rhizosphere as well as its potential for the biological control of fungi associated at seeds of the same plant. The production of chitinase enzyme was found in the genera identified as Acinetobacter, Bacterium, Burkholderia, Paenibacillus, Pseudomonas, Rhizobium, Shewanella, Sphingom...

Background and aims A major problem in all restoration and rehabilitation projects is to restore the function of the ecosystem. Nitrogen, next to water, is the most limiting factor for productivity of arid terrestrial ecosystems. Methods We used a successful restored area, completed 10 years earlier, in comparison with an undisturbed scrubland area...

Maize is a plant of great value to humanity, so the bacterial diversity in association with the cultivation is equally important. Various protocols have been developed for studied bacterial diversity associated with maize from the cultivable bacterial diversity to nonculturable bacterial diversity. In this article the importance of maize, microbial...

The rhizospheric soil interacts with substances of low molecular weight such as carboxylic acids, among other substances, whose sorption dynamics of mineral particle surface is unknown. Adsorption of water and volatile carboxylic acids from plants and bacteria (methane, ethane, propane and butane) was determined by the chromatographic method in an...

El maíz es una planta de gran importancia para México y el mundo. Es muy diverso su uso y características, por lo que resulta de interés realizar estudios de las poblaciones microbianas asociadas. El objetivo fue determinar la variabilidad bioquímica y genética de bacterias asociadas a la rizosfera de maíz, criollo amarillo, maíz criollo rojo, maíz...
