Effect of plant growth promoting rhizobacteria (PGPR) inoculation on microbial community structure in rhizosphere of forage corn cultivated in Thailand
The results demonstrated that dominant species in microbial community structure were not interfered by PGPR, but strongly influenced by plant development. Expand
Natural abundance of 15N in tropical plants with emphasis on tree legumes
The δ 15N values of Panicum maximum and leguminous trees, except Leucaena leucocephala, were similar to those of non-N2-fixing trees, suggesting that the contribution of fixed N in these plants is negligible, and it is confirmed that these species are non-nodulating legumes. Expand
Mineral constraints to nitrogen fixation
It is concluded that the whole legume-Rhizobium symbiosis should be considered when improving legume growth and yield under nutrient stress conditions. Expand
Growth, Survival and Field Performance of Bradyrhizobial Liquid Inoculant Formulations with Polymeric Additives
Liquid inoculant has become a preferred method for inoculating legumes with bradyrhizobia. Finely ground peat has been the standard of quality for inoculants for many years. Suitable peat for anExpand
Diversity of endophytic actinomycetes in mandarin grown in northern Thailand, their phytohormone production potential and plant growth promoting activity
The results indicated that the shoot height, fresh shoot weight and fresh root weight of the seedlings were promoted by the inoculation of endophytic actinomycetes, with values ranging from 20.2 to 49.6%, and 1.6 to 102% over the control. Expand
The communities of endophytic diazotrophic bacteria in cultivated rice (Oryza sativa L.)
It is demonstrated that nifH gene expression could be differently detected in each part and growth stage of rice plants as well as being influenced by soil nitrogen status, and plant tissue type was found to dictate the endophytic diazotrophic community structure rather than the type of soil or fertilizer amendment.

The Type III Secretion System (T3SS) is a Determinant for Rice-Endophyte Colonization by Non-Photosynthetic Bradyrhizobium
The results suggest that T3SS is one of the important determinants modulating rice infection; however, type IV secretion system and peces may also be responsible for the early steps of rice infection. Expand
Survival of Cowpea Rhizobia in Soil as Affected by Soil Temperature and Moisture
From these results, it appears that rhizobial strains to be used for inoculant production should be screened under simulated field conditions for enhanced survival before their selection for commercial inoculants production. Expand
Identification of two clusters of genes involved in salt tolerance in Sinorhizobium sp. strain BL3
When two clusters of genes involved in salt tolerance were transferred to salt-sensitive Rhizobium and Bradyrhizobiam, the transconjugants showed increased tolerance to salt stress. Expand
The alternative sigma factor RpoH2 is required for salt tolerance in Sinorhizobium sp. strain BL3.
Results indicate that RpoH2 is required for salt tolerance in Sinorhizobium sp. Expand
