Aeschynomene Aspera L., Nitrogen Fixing Stem Nodulation Plant From Manipur
نویسنده
چکیده
Aeschynomene aspera L. is a wild annual legume growing in periodically waterlogged soils in Manipur, India with profuse stem nodulation. Nodules are formed on the stem at the emergence of lateral root primordia, called nodulation sites. They are distributed on vertical rows all along the stem and branches. Stem nodules are hemispherical in shaped, dark green outside and contain a red-pigmented central zone. Stem nodules exhibit high nitrogen-fixing potential being detected by micro Kjeldahl method. The amount of Nitrogen (N) content (%) found in term of kg N per kg dry weight was as 2.4x10-7 ± 1x10-7 kg from the 45-50 days old stem nodules. Because of nitrogen fixing potential and its ability to grow in waterlogged conditions, A. aspera L. could be introduced as organic manure into the rice cropping system in Manipur.

NodD1 and NodD2 Are Not Required for the Symbiotic Interaction of Bradyrhizobium ORS285 with Nod-Factor-Independent Aeschynomene Legumes
Photosynthetic Bradyrhizobium strain ORS285 forms nitrogen-fixing nodules on the roots and stems of tropical aquatic legumes of the Aeschynomene genus. Depending on the Aeschynomene species, this symbiotic interaction does or does not rely on the synthesis of Nod-factors (NFs). However, whether during the interaction of Bradyrhizobium ORS285 with NF-independent Aeschynomene species the nod gene...

Nitrogen fixation in the legume-rhizobium symbiosis is a crucial area of research for more sustainable agriculture. Our knowledge of the plant cascade in response to the perception of bacterial Nod factors has increased in recent years. However, the discovery that Nod factors are not involved in the Aeschynomene-Bradyrhizobium spp. interaction suggests that alternative molecular dialogues may e...

We investigated the presence of endophytic rhizobia within the roots of the wetland wild rice Oryza breviligulata, which is the ancestor of the African cultivated rice Oryza glaberrima. This primitive rice species grows in the same wetland sites as Aeschynomene sensitiva, an aquatic stem-nodulated legume associated with photosynthetic strains of Bradyrhizobium. Twenty endophytic and aquatic iso...

Nodulation ability of 15 Rhizobium strains isolated from root and stem nodules of tropical Aeschynomene species was studied on 20 different Aeschynomene species and four other legumes-Arachis hypogaea, Stylosanthes guianensis, Macroptilium atropurpureum, and Sesbania rostrata. The results of this investigation showed that Aeschynomene species could be divided into three groups according to the ...
