tropical legume supplementation influences microbial protein synthesis and rumen ecology.	four rumen-fistulated male swamp buffaloes, 5-year-old with initiated live weight at 360 ± 12 kg, were randomly assigned according to a 4 × 4 latin square design to investigate the effect of feeding high level of dried leucaena leaf (dll) on feed intake, fermentation efficiency and microbial protein synthesis. the dietary treatments were the feeding levels of dll at 0, 2, 4 and 6 kg/head/day. all buffaloes were supplemented with concentrate mixtures at 0.1% of body weight, and rice straw was fed ...	2016	27079697
nrcr, a new transcriptional regulator of rhizobium tropici ciat 899 involved in the legume root-nodule symbiosis.	the establishment of nitrogen-fixing rhizobium-legume symbioses requires a highly complex cascade of events. in this molecular dialogue the bacterial nodd transcriptional regulators in conjunction with plant inducers, mostly flavonoids, are responsible for the biosynthesis and secretion of nod factors which are key molecules for successful nodulation. other transcriptional regulators related to the symbiotic process have been identified in rhizobial genomes, including negative regulators such as ...	2016	27096734
comparison of the effects of mesquite pod and leucaena extracts with phytoestrogens on the reproductive physiology and sexual behavior in the male rat.	mesquite (prosopis sp.) and leucaena leucocephala are widespread legumes, widely used to feed several livestock species and as food source for human populations in several countries. both mesquite and leucaena contain several phytoestrogens which might have potential estrogenic effects. thus, the aim of this study was to evaluate the effects of mesquite pod and leucaena extracts on several aspects of behavior and reproductive physiology of the male rat. the effects of the extracts were compared ...	2016	27163522
native rhizobia from zn mining soil promote the growth of leucaena leucocephala on contaminated soil.	plants on contaminated mining soils often show a reduced growth due to nutrient depletion as well as trace elements (tes) toxicity. since those conditions threat plant's survival, plant growth-promoting rhizobacteria (pgprs), such as rhizobia, might be of crucial importance for plant colonization on te-contaminated soils. native rhizobia from mining soils are promising candidates for bioaugmented phytoremediation of those soils as they are adapted to the specific conditions. in this work, rhizob ...	2017	27409290
a putative 3-hydroxyisobutyryl-coa hydrolase is required for efficient symbiotic nitrogen fixation in sinorhizobium meliloti and sinorhizobium fredii ngr234.	we report that the smb20752 gene of the alfalfa symbiont sinorhizobium meliloti is a novel symbiotic gene required for full n2 -fixation. deletion of smb20752 resulted in lower nitrogenase activity and smaller nodules without impacting overall nodule morphology. orthologs of smb20752 were present in all alpha and beta rhizobia, including the ngr_b20860 gene of sinorhizobium fredii ngr234. a ngr_b20860 mutant formed fix(-) determinate nodules that developed normally to a late stage of the symbios ...	2017	27727485
ensifer shofinae sp. nov., a novel rhizobial species isolated from root nodules of soybean (glycine max).	two bacterial strains isolated from root nodules of soybean were characterized phylogenetically as members of a distinct group in the genus ensifer based on 16s rrna gene comparisons. they were also verified as a separated group by the concatenated sequence analyses of reca, atpd and glnii (with similarities ≤93.9% to the type strains for defined species), and by the average nucleotide identities (ani) between the whole genome sequence of the representative strain ccbau 251167(t) and those of th ...	2017	28209394
potential of different am fungi (native from as-contaminated and uncontaminated soils) for supporting leucaena leucocephala growth in as-contaminated soil.	arbuscular mycorrhizal (am) fungi inoculation is considered a potential biotechnological tool for an eco-friendly remediation of hazardous contaminants. however, the mechanisms explaining how am fungi attenuate the phytotoxicity of metal(oid)s, in particular arsenic (as), are still not fully understood. the influence of as on plant growth and the antioxidant system was studied in leucaena leucocephala plants inoculated with different isolates of am fungi and exposed to increasing concentrations ...	2017	28214191
fungal planet description sheets: 469-557.	novel species of fungi described in this study include those from various countries as follows: australia: apiognomonia lasiopetali on lasiopetalum sp., blastacervulus eucalyptorum on eucalyptus adesmophloia, bullanockia australis (incl. bullanockia gen. nov.) on kingia australis, caliciopsis eucalypti on eucalyptus marginata, celerioriella petrophiles on petrophile teretifolia, coleophoma xanthosiae on xanthosia rotundifolia, coniothyrium hakeae on hakea sp., diatrypella banksiae on banksia for ...	2016	28232766
proteomic characterization and schizophyllan production by schizophyllum commune istl04 cultured on leucaena leucocephala wood under submerged fermentation.	in this study schizophyllum commune istl04 was grown on leucaena leucocephala wood (llw) for secretome analysis and schizophyllan production. there is no report on extracellular protein profile and schizophyllan production on woody biomass by this fungus under submerged fermentation conditions. leucaena leucocephala, a promising bioenergy crop having high holocellulose content was used as substrate without pretreatment. the maximum sugar, extracellular protein and exopolysaccharide (eps) product ...	2017	28390274
