Sesbania
''Sesbania'' is a genus of flowering plants in the pea family, Fabaceae, and the only genus found in tribe Sesbanieae. Riverhemp is a common name for plants in this genus. Notable species include the rattlebox (''Sesbania punicea''), spiny sesbania (''Sesbania bispinosa''), and '' Sesbania sesban'', which is used in cooking. Plants of this genus, some of which are aquatic, can be used in alley cropping to increase the soil's nitrogen content. The species of rhizobia responsible for nitrogen fixation in ''Sesbania rostrata'' is ''Azorhizobium caulinodans''. Some 60 species are currently accepted, with about 39 still unresolved. The largest number of species are found in Africa, and the remainder in Australia, Hawaii, and Asia. Fossil record Fossil seed pods from the upper Oligocene resembling ''Sesbania'' have been found in the Hungarian locality of Eger Wind-brickyard. The fossil species grew in a swampy and riparian environment.Distribution of Legumes in the Tertiary of Hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sesbania Drummondii
''Sesbania drummondii'', known as poisonbean, rattlebox and rattlebush, is a medium-sized perennial shrub in the legume family Fabaceae. It is native to the southeastern United States, from Texas east to Florida. These woody-based shrubs grow from tall. It is usually much branched in the upper portion. Branches are thin and widely spreading. The medium green leaves are alternate, deciduous, and pinnately compound. There are typically 12-24 leaflets, and occasionally as many as 60 are found. Each leaflet is oblong shaped and long. The orange-yellow, pea-like flowers occur in a drooping raceme on a long stem. They are often found with red lining. The seed pods are four-sided, four-winged, and about long. The peas rattle inside, giving this plant its common name of Rattlebush. Inside the pods, the seeds are separated by transverse partitions. These plants flower from May to October, usually retaining many of the seed pods, which remain attached until the plant dies back to gro ...

Rhizobia
Rhizobia are diazotrophic bacteria that fix nitrogen after becoming established inside the root nodules of legumes (Fabaceae). To express genes for nitrogen fixation, rhizobia require a plant host; they cannot independently fix nitrogen. In general, they are gram negative, motile, non- sporulating rods. Rhizobia are a "group of soil bacteria that infect the roots of legumes to form root nodules". Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen. From here, the nitrogen is exported from the nodules and used for growth in the legume. Once the legume dies, the nodule breaks down and releases the rhizobia back into the soil where they can live individually or reinfect a new legume host. History The first known species of rhizobia, ''Rhizobium leguminosarum'', was identified in 1889, and all further species were initially placed in the ...

Sesbania Punicea
''Sesbania punicea'' (Spanish gold, rattlebox, or scarlet sesban) is an ornamental shrub with reddish-orange flowers. It has deciduous leaves and grows to a height of 15 feet (4.5 m). This plant has a high demand for water, and thrives in swamps or wet areas. It requires a mildly acidic soil, with a pH between 6.1 and 6.5. Distribution The species is native to Brazil, Argentina, Paraguay and Uruguay. It has spread to other parts of South America and many coastal southern United States as well as to parts of Africa. Due to its high demand for water, this species is often found on marshy shorelines. It also forms dense thickets and thrives in disturbed areas. Taxonomy The genus ''Sesbania'' is within the larger family Fabaceae. The Fabaceae are divided into three subfamilies: * Mimosoideae (80 genera and 3,200 species) **Caesalpinioideae (170 genera and 2,000 species) *** Faboideae (470 genera and 14,000 species) The genus'' Sesbania'' belongs to the subfamily Faboideae, whi ...
