Initial stages in the morphogenesis of nitrogen-fixing stem nodules of Sesbania rostrata.
Morphogenesis of stem nodules in Sesbania rostrata was studied over a period of 6 days after inoculation with an appropriate species of Rhizobium. Nodulation sites were initially slightly raised, circular areas 0.3 to 0.6 mm in diameter and 4 to 5 mm apart in vertical rows along the length of the stem. Each site was underlaid by an adventitious root primordium. A site became susceptible to infe...
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...

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...

Nodule-enhanced protease inhibitor gene: emerging patterns of gene expression in nodule development on Sesbania rostrata.
A novel marker for the early stages of nodulation of Sesbania rostrata was found to encode a putative member of the Kunitz family of protease inhibitors (SrPI1). Its expression was enhanced during nodulation, and was not up-regulated by wounding or upon infection with wide host-range pathogens. In situ expression patterns resembled those previously described for functions that may be implicated...
