Use of Frankia and Actinorhizal Plants for Degraded Lands Reclamation
Degraded lands are defined by soils that have lost primary productivity due to abiotic or biotic stresses. Among the abiotic stresses, drought, salinity, and heavy metals are the main threats in tropical areas. These stresses affect plant growth and reduce their productivity. Nitrogen-fixing plants such as actinorhizal species that are able to grow in poor and disturbed soils are widely planted...
متن کاملSymbiosis between Frankia and actinorhizal plants: root nodules of non-legumes.
In actinorhizal symbioses, filamentous nitrogen-fixing soil bacteria of the genus Frankia induce the formation of nodules on the roots of a diverse group of dicotyledonous plants representing trees or woody shrubs, with one exception, Datisca glomerata. In the nodules, Frankia fixes nitrogen and exports the products to the plant cytoplasm, while being supplied with carbon sources by the host. P...

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...
متن کاملActinorhizal, mycorhizal and rhizobial symbioses: how much do we know?
The symbiotic association between certain plants and microorganisms plays an important role in soil fertilization, and improves their growth and mineral nutrition. Microorganisms implicated in this symbiotic interaction are from two groups: bacteria and fungi. The bacteria group is implicated on nitrogen fixation (for review see Pawlowski and Bisseling, 1996), while the fungal group is involved...
