Molecular diversity of Frankia in root nodules of Alnus incana grown with inoculum from polluted urban soils.
ABSTRACT The establishment and growth of trees can be compromised by soil contamination which can reduce populations of key microbial symbionts. We describe the colonisation of grey alder (Alnus incana) by Frankia from 10 urban soils with varying degrees of organic and inorganic pollution. Principal components analysis (PCA) of soil chemical profiles showed a separation of remediated and unreme...
متن کاملMicromonospora lupini sp. nov. and Micromonospora saelicesensis sp. nov., isolated from root nodules of Lupinus angustifolius.
A study was conducted to determine the taxonomic status of six actinomycete strains isolated from root nodules of Lupinus angustifolius. The strains were filamentous, Gram-positive and produced single spores at the tip of the hyphae. Phylogenetic, chemotaxonomic and morphological analyses demonstrated that all six strains belonged to the genus Micromonospora. According to the 16S rRNA gene sequ...
متن کاملA freeze-fracture electron microscopic study of Frankia in root nodules of Alnus incana grown at three oxygen tensions
ABEYSEKERA, R. M., NEWCOMB, W . , SILVESTER, W. B., and TORREY, J. G. 1990. A freeze-fracture electron microscopic study of Frankia in root nodules of Alnus incana grown at three oxygen tensions. Can. J. Microbiol. 36: 97-108. Nodulated plants of Alnus incana ssp. rugosa and ssp. incana were grown with the roots exposed to 5,21, and 40 kPa 02. The nodules were studied by freeze-fracture transmi...
متن کاملBurkholderia mimosarum sp. nov., isolated from root nodules of Mimosa spp. from Taiwan and South America.
Fourteen strains were isolated from nitrogen-fixing nodules on the roots of plants of the genus Mimosa growing in Taiwan, Brazil and Venezuela. On the basis of 16S rRNA gene sequence similarities, all of the strains were previously shown to be closely related to each other and to belong to the genus Burkholderia. A polyphasic approach, including DNA-DNA reassociation, whole-cell protein analysi...
متن کاملP.B. (2015) Mesorhizobium waimense sp. nov. isolated from Sophora longicarinata root nodules and Mesorhizobium cantuariense sp. nov. isolated from Sophora microphylla root
31 32 In total 14 strains of gram-negative, rod-shaped bacteria were isolated from Sophora 33 longicarinata and Sophora microphylla root nodules and authenticated as rhizobia on these 34 hosts. Based on the 16S rRNA gene phylogeny, they were shown to belong to the genus 35 Mesorhizobium, and the S. longicarinata strains were most closely related to Mesorhizobium 36 amorphae ACCC 19665 (99.8 – 9...
