Erythrina velutina ("mulungu") is a legume tree from Caatinga that associates with rhizobia but the diversity and symbiotic ability of "mulungu" rhizobia are poorly understood. The aim of this study was to characterize "mulungu" rhizobia from Caatinga. Bacteria were obteined from Serra Talhada and Caruaru in Caatinga under natural regeneration. The bacteria were evaluated to the amplification o...

Maize (Zea mays L.) is one of the most important cereals for Mexico and humanity. The Yaqui Valley -located in northwest Mexico- agricultural regions worldwide, it characterized by an indiscriminate use inorganic fertilizers improving crop yields, leading to increased environmental economic cost maize production. Here, a morphological, metabolic, molecular characterization native bacteria assoc...

Rhizobium leguminosarum bv. viciae RCAM1026 is a strain first isolated in 1964 from nodules of "Ramensky 77" cultivar of garden pea (Pisum sativum L.) now routinely used as a model strain in inoculation experiments on pea. Assembly with SPAdes yielded 133 contigs longer then 200 bp (N50 = 202,321, GC% = 60.84). Resulting annotated genome is 7,248,686 bp encoding 6792 genes.

in order to study the response of concentration and composition of essential oil of coriander (coriandrum sativum) to cattle manure and nitrogen fixing bacteria, an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in damavand of iran in 2010. the factors were cattle manure i...

The field experiment was conducted during Rabi season, 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. objective to study the influence Biofertilizers Phosphorous application on growth yield field- pea (Pisum sativum L.). results showed that treatment 9 [Phosphate-solubilizing bacteria (PSB) +...

Three cDNAs (ext3, ext127, and ext26), originally isolated by differential screening from a root-hair cDNA library of Vigna unguiculata, were found to encode extensin-like cell wall proteins. Transcripts homologous to these cDNAs were only detected in root hairs where mRNA levels decreased 1 day after inoculation with rhizobia. This coincided with the onset of root-hair deformation, the first m...
