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 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 کاملPermanent Draft Genome Sequence of Frankia sp. Strain AvcI1, a Nitrogen-Fixing Actinobacterium Isolated from the Root Nodules of Alnus viridis subsp. crispa Grown in Canada.
Frankia strain AvcI1, isolated from root nodules of Alnus viridis subsp. crispa, is a member of Frankia lineage Ia, which is able to reinfect plants of the Betulaceae and Myricaceae families. Here, we report a 7.7-Mbp draft genome sequence with a G+C content of 72.41% and 6,470 candidate protein-encoding genes.
متن کاملDistribution of Frankia genotypes occupying Alnus nepalensis nodules with respect to altitude and soil characteristics in the Sikkim Himalayas
doi: 10.1111/j.1399-3054.2006.00872.x We investigated the distribution of Frankia genotypes with respect to three altitudinal zones in the Sikkim Himalayas. The study was carried out for 90 Alnus nepalensis trees at nine different locations from three altitudes from the east and north districts of Sikkim, India. We used a PCR-based technique to amplify the internally transcribed spacer (ITS) re...
متن کاملPhylogeny and assemblage composition of Frankia in Alnus tenuifolia nodules across a primary successional sere in interior Alaska.
In nitrogen (N) fixing symbioses, host-symbiont specificity, genetic variation in bacterial symbionts and environmental variation represent fundamental constraints on the ecology, evolution and practical uses of these interactions, but detailed information is lacking for many naturally occurring N-fixers. This study examined phylogenetic host specificity of Frankia in field-collected nodules of...
