Diversity, Phylogeny and Plant Growth Promotion Traits of Nodule Associated Bacteria Isolated from .

spp. are widely used as a forage to improve pastures, and inoculation with elite rhizobial strains is a common practice in many countries. However, only a few species have been studied in the context of plant-rhizobia interactions.

Characterization of sub-nuclear changes in Caenorhabditis elegans embryos exposed to brief, intermediate and long-term anoxia to analyze anoxia-induced cell cycle arrest.

Background: The soil nematode C. elegans survives oxygen-deprived conditions (anoxia; <.001 kPa O2) by entering into a state of suspended animation in which cell cycle progression reversibly arrests.
