Understanding the expression dynamics of symbiont rhizobial nifH and nitrogen assimilatory NR and GS genes in dry bean (Phaseolus vulgaris L.) genotypes at various growth stages
Abstract:Selection of dry bean (Phaseolus vulgaris L.) cultivars based on their symbiotic nitrogen fixation (SNF) could reduce the fertilizer N requirement. The nifH gene in the bacterial symbiont facilitates the organic N assimilation by N‐assimilatory enzymes, nitrate reductase (NR), and glutamine synthetase (GS). Fertilizer‐N recommendation of legumes could be adjusted with the relative potential of bacterial nifH gene expression. We hypothesized that quantification of bacterial and plant marker gene expression coul… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
