Chickpea (Cicer arietinum L.) is globally cultivated due to its high nutritional value. As with other legumes, success depends greatly on inoculation effective symbiotic rhizobial strains. Since agricultural importance as an alternative winter crop in Argentina very recent, there are limited phylogenetic studies the affiliation and origin of two strains used for here. We attempted define their ...

Our understanding of bee phylogeny has improved over the past fifteen years as a result of new data, primarily nucleotide sequence data, and new methods, primarily model-based methods of phylogeny reconstruction. Phylogenetic studies based on single or, more commonly, multilocus data sets have helped resolve the placement of bees within the superfamily Apoidea; the relationships among the seven...
