Research ArticleOpen accessEvery word in the titleISOLATION AND CHARACTERIZATION OF RHIZOBIA AND PLANT GROWTH-PROMOTING RHIZOBACTERIA AND THEIR EFFECTS ON GROWTH OF RICE SEEDLINGSK. Z. Tan, O. Radziah, M. S. Halimi et al.Biofertilizer is a relatively safer, environmentally friendly and cost-effective approach as an alternative to reduce chemical fertilizer usage. The selection of bacterial strains with multiple beneficial characteristics are important to maximize the effectiveness on the host plant. Due to aforementioned interest, several Plant Growth-Promoting Rhizobacterial (PGPR) and rhizobial strains were isolated from rice and legume roots, respectively, at four locations … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 15 Apr 2014 · 10,904 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleResponse of Root Properties to Tripartite Symbiosis between Lucerne (Medicago sativa L.), Rhizobia and Mycorrhiza Under Dry Organic Farming ConditionsM. R. Ardakani, G. Pietsch, A. Moghaddam et al.Problem statement: It is generally considered that root turnover is a major contributor to organic matter and mineral nutrient cycles in organic managed agroecosystems. Approach: This study designed to investigate whether microbial activity could affect on root properties of Lucerne in an organically managed field under dry weather conditions. The trial was laid out as a factorial experiment in the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,504 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEnhanced Survival and Nodule Occupancy of Pigeon pea Nodulating Rhizobium sp. ST1 expressing fegA Gene of Bradyrhizobium japonicum 61A152Falguni R. Joshi, Dhwani K. Desai, G. Archana, Anjana J. DesaiProblem statement: Rhizobial isolates belonging to genera (Rhizobium sp. and Mesorhizobium sp.) in our laboratory produced only catecholate type of siderophores. Although FhuA and FegA (ferrichrome receptors) homologs were found to be present in the sequenced genomes of few rhizobia (e.g., 1 in R. etli and 2 in Mesorhizobium sp. BNC1), laboratory isolates of the corresponding genera failed to utilize … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 30 Jun 2009 · 7,865 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAgro-Process Intensification through Synthetic Rhizosphere Media for Nitrogen Fixation and Yield Enhancement in PlantsG. Akay, D. R. BurkeProblem statement: In order to combat global warming and the emerging Food, Energy and Water shortages (FEWs), several approaches have been adopted, including genetic engineering and farming practices. Biomass based energy technology will further stress food and water resources and hence novel holistic approaches to FEWs should be designed. Approach: A novel technique (Agro-Process Intensification, A-PI) which simultaneously addresses FEWs … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 15 Mar 2012 · 8,599 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGrowth Enhancement and Disease Reduction of Soybean by 1-Aminocyclopropane-1-Carboxylate Deaminase-Producing PseudomonasEdi Husen, Aris Tri Wahyudi, Antonius Suwanto, GiyantoProblem statement: 1-Aminocyclopropane-1-Carboxylate (ACC) deaminase-producing bacteria have been known to ameliorate the inhibition-effect of increase concentration of ethylene in higher plants, which can be triggered by high concentration of indole-3-Acetic Acid (IAA) and/or by the presence of plant pathogens. This study examined the potential use of Pseudomonas isolates producing ACC deaminase as well as IAA to enhance soybean growth and … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 7,911 accessesView PDF Cite
