Roots of seedlings of the "beefwood" tree, Casuarina cunninghamiana Miq. grown in nitrogenfree nutrient solution were inoculated with a suspension prepared from crushed root nodules taken from mature plants. Marked deformation of root hairs was evident but no infection threads were observed in root hairs. The mode of infection remains undetermined. Root nodules were initiated within three weeks...

8 strains of endophytic actinomycetes were successfully isolated from root nodules of Elaeagnus angustifolia by the methord of nodule-slicing respectively on three mediums S, FTW and DPM. And these strains were analyzed by 16S rDNA phylogenetic studies, the result showed that 5 of these strains belonged to Micromonospora, and the other 3 strains was Nonomuraea, Pseudonocardia and Planotetraspor...

UNLABELLED PREMISE OF STUDY A survey of the root-nodule symbiosis in Astragalus and its interaction with selenium (Se) has not been conducted before. Such studies can provide insight into how edaphic conditions modify symbiotic interactions and influence partner coevolution. In this paper plant-organ Se concentration ([Se]) was investigated to assess potential Se exposure to endophytes. • ...
