Nitrogen fixation ofSesbania rostrata: Contribution of stem nodules to nitrogen acquisition

Role of Abscisic Acid in Flood-Induced Secondary Aerenchyma Formation in Soybean (Glycine max) Hypocotyls

“…Under flooded conditions, the phellogen also develops a homologous tissue, secondary aerenchyma, in the stems, roots, and root nodules in some plant species. Examples include some Fabaceae plants such as Sesbania aculeata (Scott and Wager, 1888), Sesbania rostrata (Saraswati et al, 1992;Shiba and Daimon, 2003), Neptunia oleracea (Metcalfe, 1931), Melilotus siculus (Teakle et al, 2011;Verboven et al, 2012), and Viminaria juncea (Walker et al, 1983). In addition, this phenomenon is observed in Onagraceae, e.g., Ludwigia spp.…”

Secondary Aerenchyma Formation and its Relation to Nitrogen Fixation in Root Nodules of Soybean Plants (Glycine max) Grown under Flooded Conditions

“…The infected tissue of the nodules in these leguminous plants is pink, and the nitrogenase activity is highly maintained, even under flooded conditions (Walker et al, 1983;James and Crawford, 1998;James and Sprent, 1999). Some research has demonstrated using 15N as a tracer that atmospheric nitrogen entered into the aerenchyma developing in the stem above the water level, and was transported to the flooded nodules via aerenchyma under nitrogen gas deficient conditions in flooded soils (Walker et al, 1983;Saraswati et al, 1992). Soybean, which is one of the important leguminous crops, is considered to be susceptible to flooding stress because the plant has a limited ability to form secondary aerenchyma (Arikado, 1954).…”

Texasweed (Caperonia palustris) Can Survive and Reproduce in 30-cm Flood

“…Similar tissue production under flooded conditions has been reported in soybean (Glycine max L.), purple loosestrife (Lathyrum salicaria L.), and sesbania (Sesbania spp.) (Saraswati et al 1992;Shiba and Daimon 2003;Shimamura et al 2003;Stevens et al 2002). The tissue was described as secondary aerenchyma and was called phellem (Shimamura et al 2003).…”
