Última Arbuscular mycorrhizal fungal communities in the rhizosphere of a continuous cropping soybean system at the seedling stage BJM Cui,Jiaqi; Bai,Li; Liu,Xiaorui; Jie,Weiguang; Cai,Baiyan. Abstract Arbuscular mycorrhizae (AM) fungi play a crucial role in the growth of soybean; however, the planting system employed is thought to have an effect on AM fungal communities in the rhizosphere. This study was performed to explore the influence of continuous soybean cropping on the diversity of Arbuscular mycorrhizal (AM) fungi, and to identify the dominant AM fungus during the seedling stage. Three soybean cultivars were planted under two and three years continuous cropping, respectively. The diversity of AM fungi in the rhizosphere soil at the seedling stage was subsequently analyzed using polymerase chain reaction (PCR)-denaturing gradient gel electrophoresis (DGGE). The results showed that an increase in cropping years improved the colonization...

BACKGROUND: Big-leaf mahogany (Swietenia macrophylla King) is the woody species with the highest economic value in Latin America. Currently, it is subject to intensive exploitation, diminishing its natural populations. Due to this decline, the species is a preferred species for reforestation and establishment of commercial tropical plantations. Mycorrhizal symbiosis is a biotic factor scarcely studied in the ecology of this species. Therefore, the objective of this research was to identify the diversity of arbuscular mycorrhizal fungi (AMF) species associated with the rhizosphere of seedlings and mature trees of big-leaf mahogany growing in its natural habitat, a tropical rain forest in Los Tuxtlas, Veracruz, Mexico. Soil samples from a 20-cm depth were... Tipo: Journal article Palavras-chave: Arbuscular mycorrhizae; Morphospecies; Seedlings; Spores; Tropical trees.

Como respuesta a la estacionalidad, fenología y defoliación en el trópico seco Colegio de Postgraduados Cortés Sarabia, Jazmín. La ilama es una planta frutícola tropical, cuya distribución se encuentra restringida a México, Centroamérica y parte de Sudamérica y cuyo cultivo es de importancia local. Dado el escaso conocimiento sobre la dinámica microbiana en este tipo de cultivo, este estudio tuvo como objetivo evaluar el efecto de la estacionalidad, fenología y defoliación sobre la dinámica poblacional microbiana en filósfera y rizosfera de plantas de ilama (Annona diversifolia Saff.), en campo e invernadero. Se evaluaron plantas de tres edades en cuatro épocas del año en San Antonio de las Huertas, Guerrero. Se evaluaron las unidades formadoras de colonias (UFC) de hongos, actinomicetos, bacterias totales así como bacterias fijadoras de nitrógeno pertenecientes a los...

S.; Cardoso,E. J. B. N.. The objective of this experiment was to quantify the extramatrical mycelium of the arbuscular mycorrhizal (AM) fungus Glomus etunicatum (Becker & Gerdemann) grown on maize (Zea mays L. var. Piranão) provided with various levels of phosphate fertilizer and harvested at 30, 60 and 90 days after planting (DAP). Total extramatrical mycelium (TEM) was extracted from soil using a modified membrane filtration method, followed by quantification using a grid intersection technique. Active extramatrical mycelium (AEM) proportion was determined using an enzymatic method which measured dehydrogenase activity by following iodonitrotetrazolium reduction. At low levels of added P, there was relatively less TEM than at high levels of added P, but the AEM...
