Bradyrhizobia from wild Phaseolus, Desmodium, and Macroptilium species in northern Mexico.
rRNA genetic markers were analyzed in 97 isolates of nodule bacteria from six legume species in Chihuahua, Mexico. The most common genotypes were widely shared across host species and had 16S rRNA sequences identical to those of strains from an eastern North American legume (Amphicarpaea) that are closely related to Bradyrhizobium elkanii.
متن کاملNative bradyrhizobia from Los Tuxtlas in Mexico are symbionts of Phaseolus lunatus (Lima bean).
Los Tuxtlas is the northernmost rain forest in North America and is rich in Bradyrhizobium with an unprecedented number of novel lineages. ITS sequence analysis of legumes in polycultures from Los Tuxtlas led to the identification of Phaseolus lunatus and Vigna unguiculata in addition to Phaseolus vulgaris as legumes associated with maize in crops. Bacterial diversity of isolates from nitrogen-...
متن کاملTwo new species of Chiropterotriton (Caudata: Plethodontidae) from northern Mexico.
Species of the genus Chiropterotriton are distributed through much of northern and eastern Mexico. The genus has presented taxonomic difficulties, with a number of species waiting to be described. We describe two new species, Chiropterotriton cieloensis sp. nov. and Chiropterotriton infernalis sp. nov., from the Mexican state of Tamaulipas based on both molecular and morphological data. We pres...
متن کاملMolecular diversity of native bradyrhizobia isolated from lima bean (Phaseolus lunatus L.) in Peru.
The diversity of a collection of 21 bradyrhizobial isolates from Lima bean (Phaseolus lunatus L.) was assayed by molecular methods. Moderately high to high genetic diversity was revealed by multilocus enzyme electrophoresis (MLEE) analysis of seven enzyme loci and genomic fingerprints with ERIC and BOX primers. Two groups with differences in growth rate were found among the isolates and their d...
