Nitrogenase Activity and Amounts of Nitrogenase Proteins in a Frankia-Alnus incana Symbiosis Subjected to Darkness.
Effects of prolonged darkness on nitrogenase activity in vivo, nitrogenase activity in vitro, and the amounts of nitrogenase proteins were studied in symbiotic Frankia. Plants of Alnus incana (L.) Moench in symbiosis with a local source of Frankia were grown for 9 to 10 weeks in an 18/6 hour light/darkness cycle. After 12 hours of a light period, the plants were exposed to darkness for up to 40...
متن کاملAssessing the phylogeny of Frankia-actinorhizal plant nitrogen-fixing root nodule symbioses with Frankia 16S rRNA and glutamine synthetase gene sequences.
Actinomycetes from the genus Frankia induce nitrogen-fixing root nodules on actinorhizal plants in the "core rosid" clade of eudicots. Reported here are nine partial Frankia 16S rRNA gene sequences including the first from host plants of the rosaceous genera Cercocarpus and Chamaebatia, 24 partial glutamine synthetase (GSI; glnA) sequences from Frankia in nodules of 17 of the 23 actinorhizal ge...
متن کاملMolecular 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 کاملRegulation of nodulation in the absence of N2 is different in actinorhizal plants with different infection pathways.
Root nodulation in actinorhizal plants, like Discaria trinervis and Alnus incana, is subject to feedback regulatory mechanisms that control infection by Frankia and nodule development. Nodule pattern in the root system is controlled by an autoregulatory process that is induced soon after inoculation with Frankia. The final number of nodules, as well as nodule biomass in relation to plant biomas...
