Root Nodulation of Sesbania rostrata IBRAHIMA NDOYE , ' t FRAN ( OISE
The tropical legume Sesbania rostrata can be nodulated by Azorhizobium caulinodans on both its stem and its root system. Here we investigate in detail the process of root nodulation and show that nodules develop exclusively at the base of secondary roots. Intercellular infection leads to the formation of infection pockets, which then give rise to infection threads. Concomitantly with infection,...
متن کاملEffect of Sesbania rostrata
Microplot experiments on flooded soil infested with Hirschmanniella oryzae were conducted to investigate the influence of the legum Sesbania rostrata as a rotat ion crop with rice, Oryza sativa L. cv. Moroberekan. To avoid a green manure effect f rom S. r'ostrata, all aerial parts were removed at harvest. The dry weight of paddy, culms and leaves, and n u m b e r of culms of rice following Sesb...
متن کاملEthylene-mediated phenotypic plasticity in root nodule development on Sesbania rostrata.
Leguminous plants in symbiosis with rhizobia form either indeterminate nodules with a persistent meristem or determinate nodules with a transient meristematic region. Sesbania rostrata was thought to possess determinate stem and root nodules. However, the nature of nodule development is hybrid, and the early stages resemble those of indeterminate nodules. Here we show that, depending on the env...
متن کاملImmunolocalization of antioxidant enzymes in high-pressure frozen root and stem nodules of Sesbania rostrata.
The activities and localizations of superoxide dismutases (SODs) were compared in root and stem nodules of the semi-aquatic legume Sesbania rostrata using gel-activity assays and immunogold labelling, respectively. Nodules were fixed by high-pressure freezing and dehydrated by freeze substitution. Stem nodules showed more total and specific SOD activities than root nodules because of the presen...
متن کاملEffect of Sesbania rostrata on Hirschmanniella oryzae in Flooded Rice.
Microplot experiments on flooded soil infested with Hirschmanniella oryzae were conducted to investigate the influence of the legum Sesbania rostrata as a rotation crop with rice, Oryza sativa L. cv. Moroberekan. To avoid a green manure effect from S. rostrata, all aerial parts were removed at harvest. The dry weight of paddy, culms and leaves, and number of culms of rice following Sesbania wer...
